Best Controller for Monitors Under $300 That Fits Your Desk (2026)

A monitor that is hard to adjust or hard to share between two computers can slow a workday, because the controls sit behind the screen or cables never match the desk. The best controller for monitors under 300 in this guide solves that with a desktop dial or a switch box, so you can change settings or computers without reaching behind it.

Quick verdict on the best controller for monitors under 300

If you want one starting point, choose the BenQ Hotkey Puck G2, because it puts brightness, contrast, volume, and color mode controls on a desktop dial with three assignable function keys. It suits a BenQ DesignVue or PhotoVue monitor owner who changes color modes often and wants the on-screen menu within easy reach.

For two computers sharing one screen, choose the TESmart HKS201-P23-V2, because it carries 4K video at 60Hz with a USB 3.0 hub and EDID support for one monitor. The UGREEN CM664 15707 is the closest rival for a faster USB hub, while the ATEN CS22H suits a simple desk with built-in cables and a wired remote selector.

Quick comparison table

Use this table to narrow the list before you read the detailed sections. It compares the control type, the monitor setup, the top video resolution, and the buyer each controller fits best. Six of the seven picks are KVM switches, and one is a dedicated monitor control puck.

How we selected these monitor controllers

This guide started with the limits in the search itself: a real device that controls a monitor or the computer that drives it, a design positioned in the 300-dollar tier, and specs that suit everyday desks. Every pick meets those limits, and each adds a different strength, such as a desktop dial, dual monitor output, or a faster USB hub.

The keyword is ambiguous, because a search for a monitor controller can mean a dial that changes monitor settings or a switch that changes which computer uses the monitor. This guide covers both meanings and keeps them separate, so a buyer who wants easier brightness control does not buy a KVM switch by mistake, and a buyer who wants to share a screen does not buy a puck that only works with one monitor brand.

What a monitor controller actually controls

A monitor controller controls one of two things: the settings inside a monitor, such as brightness, contrast, volume, and color mode, or the source that feeds the monitor, such as a work laptop and a home desktop. A control puck handles the first job, while a KVM switch handles the second job, and the two devices do not replace each other.

A puck connects to a compatible monitor and opens its on-screen menu from the desk, so the user can turn a dial instead of pressing small buttons on the back or the bottom edge of the screen. A KVM switch sits between two computers and one or two monitors, and it moves the keyboard, the mouse, and the video signal from one computer to the other with a button press or a hotkey.

Knowing which job you need matters more than any single spec, because a puck cannot switch computers and a KVM switch cannot change a monitor color mode. Read the product sections with that split in mind, and match the device to the friction you feel most often: reaching for monitor buttons, or swapping cables between computers.

Why a puck and a KVM solve different problems

A puck solves a reach and speed problem, because monitor buttons are small, hard to see, and often placed where a hand cannot find them without turning the screen. A dial on the desk lets a designer switch from sRGB to Adobe RGB, lower brightness for evening work, or raise volume for a video call in a few seconds, without losing focus on the image.

A KVM switch solves a sharing problem, because two computers on one desk would otherwise need two keyboards, two mice, and either two monitors or a daily cable swap. A switch box lets one keyboard, one mouse, and one or two monitors serve both computers, so a work laptop and a personal desktop can share the same screen and the same desk space.

The two devices can also work together on one desk, because a BenQ monitor owner can use a puck to change color modes and a KVM switch to change computers. That combination suits a designer with a work laptop and a home desktop, but most buyers only need one of the two, so start with the problem that costs you the most time each day.

When a single monitor switch is enough

A single monitor switch is enough when one screen, one keyboard, and one mouse can serve both of your computers, because that is the most common home office setup. A work laptop and a personal desktop, a desktop and a laptop, or a desktop and a small media computer all fit this pattern, and a two port KVM switch handles the swap with one button.

A dual monitor KVM switch is worth the extra cabling only when both screens must follow the same computer at the same time, such as an extended desktop for spreadsheets, code, or video editing. If the second screen can stay on one computer while the main screen switches, a single monitor switch plus a direct cable to the second screen is simpler and easier to set up.

A puck is enough on its own when you have one computer and one compatible monitor, and your only complaint is the monitor menu. In that case a KVM switch adds cables and a box you do not need, so spend the desk space on the dial instead and keep the setup as simple as it already is.

The seven controllers in detail

Each section below follows the same pattern, so you can compare the controllers side by side. It starts with who the controller fits best, then covers the control method, the video limits, the ports, and the main trade-offs. Each profile also notes when to buy it and when to skip it.

BenQ Hotkey Puck G2

This puck fits BenQ DesignVue and PhotoVue monitor owners who change color modes, brightness, or volume often during the day. The BenQ Hotkey Puck G2 is a wired desktop dial with three single function keys and a rotation key, and the dial adjusts brightness, contrast, and volume through the monitor on-screen menu.

The puck works as a remote for the monitor menu, so the user can assign the three function keys to the features used most, such as sRGB, Adobe RGB, or M-Book mode, and the rotation key opens more shortcuts. The dial turns to move through menu items and to raise or lower a value, which is faster than pressing a row of small buttons on the monitor bezel.

BenQ lists the Hotkey Puck G2 as an included accessory with monitors such as the PD2705U and the PD3220U, and with the photographer monitor SW270C, so buyers should confirm that their own monitor model supports the puck before ordering one on its own. The puck connects to a dedicated port on the monitor, and it is not a universal controller for monitors from other brands.

The puck also suits a desk where the monitor sits far back or on an arm, because the controls move to the front of the desk within easy reach. A designer who switches color modes between a print job and a web job gains the most, while a buyer who only sets brightness once a month gains little from a dedicated dial.

Pros: A desktop dial with three assignable function keys and a rotation key, direct control of brightness, contrast, and volume, and quick color mode switching on supported BenQ monitors.

Cons: Works only with supported BenQ monitors, does not switch between computers, and does not add ports or a USB hub to the desk.

Buy it for a supported BenQ monitor where fast color mode and brightness changes matter most. Skip it if your monitor is from another brand or you need to share one screen between two computers.

TESmart HKS201-P23-V2

This switch fits buyers with two computers and one monitor who want 4K video and a fast shared USB hub. The TESmart HKS201-P23-V2 is a two port single monitor HDMI KVM switch with a USB 3.0 docking station, and it supports up to 3840 x 2160 at 60Hz with 4:4:4 color.

The switch shares one HDMI monitor, a keyboard, and a mouse between two computers, and the shared USB 3.0 hub runs at up to 5Gbps for drives, printers, and other peripherals. EDID emulation is built in, which helps each computer keep the correct display information, so windows stay in place when you switch back to a computer.

Each computer connects with one HDMI video output and one USB connection, and the single HDMI output feeds the monitor. The switch uses HDMI 2.0 with HDCP 2.2, HDR10, and Dolby Vision support in the published spec, and the front panel button and hotkey switching give two ways to change computers without reaching behind the desk.

The HKS201-P23-V2 also suits a desk that mixes a work laptop and a home desktop, because the USB hub means a printer or an external drive does not need to move between computers. A buyer who needs two monitors should look at the dual monitor TESmart model below instead, because this model drives one screen only.

Pros: 4K at 60Hz with 4:4:4 color, a USB 3.0 hub at up to 5Gbps, EDID emulation, and HDMI 2.0 with HDCP 2.2 and HDR10 support.

Cons: Drives one monitor only, needs a 12V power supply, and needs one HDMI output plus one USB connection from each computer.

Buy it for two computers sharing one 4K monitor with a shared USB hub. Skip it if you need two monitors to follow one computer, or if either computer has no free HDMI output.

TESmart HKS202-E23

This switch fits buyers with two computers and two monitors who want an extended desktop on either computer. The TESmart HKS202-E23 is a two port dual monitor HDMI KVM switch, and it supports up to 3840 x 2160 at 60Hz on each of its two HDMI outputs.

The switch connects two computers to two monitors, and it supports extended, mirrored, or one computer per monitor display modes, so a spreadsheet can span two screens on the work computer and then move to the home computer with one switch. The published spec also lists 3440 x 1440 at 100Hz and 1920 x 1080 at 240Hz as lower resolution options for wide or fast screens.

Each computer needs two HDMI video connections and one USB connection to use both monitors, which is the main setup cost of a dual monitor KVM switch, so buyers should confirm that each computer has two free video outputs before ordering. EDID emulation is built into each input port and is available in Display Mode 1, which helps keep window layouts stable when switching.

The switch also has a shared USB 2.0 peripheral port for a drive, a printer, or a scanner, plus dedicated keyboard and mouse ports with pass-through support for wired, wireless, and gaming keyboards and mice. A 3.5mm audio jack with a built-in DAC chip gives stereo audio output from the switch, which suits a desk with powered speakers.

Pros: Two HDMI monitor outputs at up to 4K at 60Hz, extended and mirrored display modes, EDID emulation in Display Mode 1, and dedicated keyboard and mouse ports.

Cons: Each computer needs two HDMI outputs for dual monitor use, the shared USB port is USB 2.0 only, and the box is larger than a single monitor switch.

Buy it for a dual monitor desk where both screens must follow the active computer. Skip it if either computer has only one video output, or if you only use one monitor.

UGREEN CM571 90478

This switch fits buyers who want a compact 4K KVM switch for two computers and one monitor on a small desk. The UGREEN CM571 90478 is a two port HDMI KVM switch, and the manufacturer manual lists support for up to 3840 x 2160 at 60Hz through HDMI 2.0.

The switch lets two computers share one HDMI monitor, a keyboard, a mouse, and USB accessories, and it has four USB 2.0 Type-A ports for the shared devices. Switching uses a button on the unit or a wired desktop controller, so the control can sit on the desk while the switch box stays near the computers.

The unit measures about 95mm by 57mm by 24mm in the published spec, which makes it one of the smallest switches in this guide and easy to fit on a crowded desk. It is driver free on Windows, macOS, and Linux in the published spec, so setup is a matter of connecting the HDMI and USB cables and pressing the button to change computers.

One point needs care: some regional listings for this model number state a lower 4K refresh rate, while the manufacturer manual lists 4K at 60Hz, so buyers who need 4K at 60Hz should confirm the rating printed on their own unit and use cables rated for that speed. The switch suits office work, study, and media use where a small box and simple switching matter most.

Pros: Compact size at about 95mm by 57mm by 24mm, 4K at 60Hz in the manufacturer manual, four USB 2.0 ports, and button or desktop controller switching.

Cons: USB 2.0 only with no USB 3.0 hub, some regional listings conflict on the top 4K refresh rate, and it drives one monitor only.

Buy it for a small desk where two computers share one 4K monitor. Skip it if you need USB 3.0 speed, dual monitors, or a guaranteed 4K at 144Hz output.

UGREEN CM664 15707

This switch fits buyers who want the same single monitor KVM job as the CM571 but with a faster USB hub. The UGREEN CM664 15707 is a two port HDMI KVM switch, and it supports up to 3840 x 2160 at 60Hz with HDMI 2.0 and HDCP 2.2 in the published spec.

The switch shares one HDMI monitor, a keyboard, and a mouse between two computers, and its shared USB hub has three USB-A 3.0 ports plus one USB-C port at up to 5Gbps. That hub suits an external drive, a printer, and a phone cable on the same desk, because the faster ports move files far quicker than the USB 2.0 hub on the smaller UGREEN model.

Each computer connects with one HDMI input and one USB-B 3.0 connection, and the single HDMI output feeds the monitor. Switching uses a top button on the unit or a wired desktop controller, and the unit takes aux power through a USB-C input, with the supply not included in the published spec, so buyers should plan for a spare USB-C power source.

The CM664 also lists backward compatibility with 4K at 30Hz, 1440p at 120Hz, and 1080p at 240Hz in the published spec, which covers a fast 1080p gaming screen as well as a 4K office screen. It suits a mixed desk where one computer edits video and the other handles office work, because the USB 3.0 hub serves both without moving cables.

Pros: 4K at 60Hz output, a USB 3.0 hub with three USB-A ports plus one USB-C port at up to 5Gbps, button or wired desktop controller switching, and HDMI 2.0 with HDCP 2.2.

Cons: Drives one monitor only, aux USB-C power supply not included, and it needs a USB-B 3.0 connection from each computer.

Buy it for two computers sharing one monitor where USB 3.0 file transfers matter. Skip it if you need dual monitors, or if you want a switch that runs without any aux power source.

ATEN CS22H

This switch fits buyers who want a simple cabled KVM switch with the cables built in and a remote selector on the desk for a tidy office. The ATEN CS22H is a two port USB 4K HDMI cable KVM switch with a remote port selector, and it supports up to 4096 x 2160 at 60Hz.

The switch uses a patented all-in-one design with integrated cables, so each computer connection is a single lead that carries HDMI, USB, and audio, which cuts cable clutter behind the desk. The remote port selector has a 1.8m cable in the published spec, so the switch button can sit on the desk while the switch box stays out of the way.

One USB keyboard, one mouse, and one HDMI monitor control two HDMI computers, and the console ports include one HDMI output, two USB Type-A ports, and 3.5mm audio jacks for speaker and microphone. The switch is bus powered by the connected computers through USB in the published spec, with an optional USB Micro-B power port for setups that need extra power.

The CS22H supports Windows, Mac, and Linux, and it supports USB hot plugging, so a keyboard or a drive can be added without restarting a computer. It suits a tidy office desk where built-in cables and a small remote button matter more than a USB 3.0 hub or a second monitor output.

Pros: Built-in 1.2m KVM cables for each computer, a wired remote port selector with a 1.8m cable, up to 4096 x 2160 at 60Hz, and bus power with no bulky adapter in most setups.

Cons: Drives one monitor only, the shared USB ports are USB 2.0, and the integrated cables cannot be swapped for longer ones.

Buy it for a tidy desk where built-in cables and a remote button matter most. Skip it if you need dual monitors, a USB 3.0 hub, or longer cables than the built-in 1.2m leads.

IOGEAR GCS62HU

This switch fits buyers who want a proven cabled KVM switch for office work and 1080p screens at a shared office desk. The IOGEAR GCS62HU is a two port USB HDMI cabled KVM switch with audio, and it supports up to 1920 x 1200 at 60Hz in the published spec.

The switch shares one HDMI monitor, a USB keyboard, and a USB mouse between two computers, and it has 2.1 stereo sound plus microphone support through 3.5mm jacks. Port switching uses a remote pushbutton, hotkeys, or a three button wired USB mouse, so the user can change computers without reaching for the switch box itself.

The KVM cables are built in at 4ft in the published spec, and the remote switch cable runs 6ft, which gives room to place the remote button on the desk while the box sits near the computers. The switch is HDCP compliant and plug and play with no software in the published spec, and it supports Windows, Mac, Linux, and Unix systems.

IOGEAR backs the GCS62HU with a 3-year warranty and free lifetime technical support in the published spec, which is the longest warranty stated among the KVM switches in this guide. The switch also supports USB 2.0 peripheral sharing through the mouse port with a powered USB hub, with mouse emulation off for that feature in the published spec.

Pros: Remote pushbutton, hotkey, and mouse switching, 2.1 stereo sound plus microphone support, built-in 4ft KVM cables with a 6ft remote cable, and a 3-year warranty.

Cons: Top resolution is 1920 x 1200 at 60Hz with no 4K support, the shared USB is USB 2.0 only, and it drives one monitor only.

Buy it for office work and 1080p screens where a long warranty and simple switching matter most. Skip it if you need 4K video, dual monitors, or a USB 3.0 hub.

Buying guide for best controller for monitors under 300

Start with the job you need done, because a puck and a KVM switch solve different problems and the wrong type wastes desk space. Then match the video resolution and the ports to your computers, check the switching method against your desk layout, and leave room for the second computer or second monitor you plan to add next.

Matching the controller to your monitor and computers

Match the controller to your monitor first, because the BenQ puck works only with supported BenQ monitors, while a KVM switch works with any monitor that has the matching video input. A buyer with a BenQ DesignVue or PhotoVue monitor can use the puck, while a buyer with a monitor from another brand should start with a KVM switch instead.

Then match the video ports to your computers, because each computer needs a free HDMI output for most switches in this guide, and a dual monitor switch needs two free video outputs from each computer. A laptop with only USB-C video needs an adapter or a dock before a HDMI KVM switch can work, so confirm the laptop video output before you order.

Also match the USB ports, because a KVM switch needs one USB host connection from each computer to move the keyboard and mouse, and a USB 3.0 hub needs USB 3.0 host ports to reach full speed. A switch with USB 2.0 ports still works for a keyboard, a mouse, and a printer, but it will not move large files quickly.

Setting up a KVM switch without losing your display settings

Set up a KVM switch one computer at a time, because connecting both computers at once makes it hard to tell which cable belongs to which machine. Connect the first computer, confirm the monitor shows its picture at the right resolution, test the keyboard and mouse, and only then connect the second computer and repeat the same test.

Then set the refresh rate and resolution in the operating system display settings, because a monitor may start at 60Hz or at a lower resolution until you change it. EDID emulation on the TESmart models helps each computer remember its display layout, but it does not replace a manual check that both computers use the same resolution and scaling.

Also label the cables and the switch inputs, because two identical HDMI leads are easy to swap by mistake when you move the desk. A short label on each lead saves a long fault-finding session later, and it makes the switch far easier to use when someone else sits at the same desk.

Mistakes to avoid at this budget tier

The most common mistake is buying a KVM switch for a monitor problem, because a switch cannot change brightness, contrast, or color mode, and a puck cannot change computers. Decide which job you need first, and buy the device that does that job, because the two types look similar in a search result but serve different needs on a desk.

Another common mistake is ignoring the video limit, because a 1080p switch such as the IOGEAR GCS62HU cannot carry a 4K signal, and a single monitor switch cannot drive two screens at once. Check the top resolution, the number of monitor outputs, and the number of video outputs each computer must supply, and match all three before you order.

A third mistake is forgetting power and cables, because some switches need a 12V adapter, some need aux USB-C power, and some run from USB bus power alone. Read the power note and the cable list for your pick, and keep a spare USB-C power source or a free wall outlet ready before the switch arrives.

Frequently asked questions

The questions below cover the choices that cause the most confusion after buyers have read the product sections. They focus on pucks versus KVM switches, video limits, and dual monitor use, because those three points decide most purchases in this group, so read them before you buy.

Is a KVM switch the best controller for monitors under 300 for two computers?

Yes, a KVM switch is the best controller for monitors under 300 for two computers, because it moves one monitor, one keyboard, and one mouse between two machines with a single button press or hotkey. A puck cannot do that job, since it only changes settings inside one compatible monitor and has no computer switching function at all.

Choose a single monitor KVM switch when one screen serves both computers, and choose a dual monitor KVM switch such as the TESmart HKS202-E23 when both screens must follow the active computer. Confirm that each computer has the video outputs the switch needs, because a dual monitor switch needs two video outputs from each computer.

A KVM switch also keeps the desk tidy, because one keyboard and one mouse replace two sets, and the shared USB hub can serve a printer or a drive from either computer. For a two computer desk, that sharing is the main gain, and it is the reason a KVM switch leads this guide for that use case.

Will a KVM switch lower my monitor resolution or refresh rate?

A KVM switch can limit resolution or refresh rate, because the video signal passes through the switch and must fit the top rating in its published spec. A 4K at 60Hz switch keeps a 4K office screen at full resolution, while a 1080p switch such as the IOGEAR GCS62HU caps the picture at 1920 x 1200 at 60Hz even when the monitor can show more.

Check the top resolution in the published spec before you buy, and use cables rated for that speed on every side of the switch. A cable rated for a lower speed can cap the picture even when the switch itself supports a higher resolution, so the cable, the computer output, and the monitor input must all match.

Also set the resolution and refresh rate in the operating system after setup, because the monitor may start at a lower setting until you change it. If the picture still looks soft after that check, test the monitor with a direct cable to confirm whether the switch or the cable is the limit.

Can one controller manage two monitors at once?

Yes, one controller can manage two monitors at once, but only a dual monitor KVM switch such as the TESmart HKS202-E23 is built for that job in this guide. It has two HDMI outputs and supports extended, mirrored, or one computer per monitor modes, so both screens can follow the active computer or split between the two machines.

A single monitor KVM switch cannot drive two monitors from one switch output, so buyers with two screens need the dual monitor model or a second direct cable for the second screen. The second screen can stay on one computer while the main screen switches, which suits a desk where only the main screen needs to change computers.

A control puck also cannot manage two monitors, because it connects to one compatible monitor and controls that screen only. For a two monitor desk, start with the dual monitor KVM switch, and add a puck only if one of the monitors is a supported BenQ model and you change its color modes often.

Conclusion

Choose the BenQ Hotkey Puck G2 for color mode and brightness control on a supported BenQ monitor, the TESmart HKS201-P23-V2 for two computers on one screen, the HKS202-E23 for a dual monitor desk, the UGREEN CM571 for a compact 4K switch, the CM664 for USB sharing, the ATEN CS22H for built-in cables, or the IOGEAR GCS62HU for 1080p office use.
