If you want one keyboard and mouse to control two computers, a monitor with a built-in KVM can cut down on desk clutter and make switching between a work laptop and desktop easier. My picks serve different setups: the LG 34WQ73A-B pairs its KVM with 90W USB-C charging for a work-focused desk, while the 34-inch Fast IPS ultrawide adds a 165Hz refresh rate for mixed gaming and productivity. For a much wider workspace, either Deco Gear 49-inch model can replace a dual-monitor arrangement.

The key tradeoffs are screen area, laptop charging, and refresh rate. A 49-inch 32:9 display gives you more room for side-by-side windows, but needs a large desk; LG’s 34-inch option offers the strongest USB-C charging but is limited to 60Hz. The two Deco Gear models share much of their core specification, so I distinguish them by the listed speaker and stand details rather than treating them as separate performance classes.
Key Takeaways
Best work-focused USB-C setup: The LG 34WQ73A-B supplies up to 90W over USB-C, more than the 65W listed for the other three picks.
Best gaming and multitasking mix: The 34-inch Fast IPS model reaches 165Hz over DisplayPort, making it the refresh-rate pick in this group.
Most screen area: Both Deco Gear 49-inch models offer 5120 × 1440 resolution in a 32:9 format, giving you room for two broad work zones.
Best fit for a compact desk: The LG and 34-inch Fast IPS models provide ultrawide workspace without the footprint of a 49-inch screen.
Check the connection path: The 34-inch Fast IPS model supports 165Hz through DisplayPort, while its HDMI input is limited to HDMI 2.0; match the port to your computer before choosing.

More Details on Our Top Picks
LG UltraWide QHD 34-Inch Curved Computer Monitor 34WQ73A-B
I rank the LG first for a desk built around switching between a work computer and another device, especially if a laptop is one of them. Its 90W USB-C power delivery is the highest listed here, so a compatible laptop can receive more power through the same connection used for display and data. Four USB ports and the integrated KVM support a shared-peripheral setup, while the 34-inch 3440 × 1440 curved IPS screen gives you useful side-by-side workspace without taking up the breadth of either 49-inch Deco Gear.
The compromise is speed. At 60Hz with a 5ms response time, this is a work-first monitor, not the pick for high-frame-rate gaming; the 34-inch Fast IPS option reaches 165Hz, and the Deco Gear models reach 120Hz. LG also lists one HDMI input, so check that your device connections fit your arrangement. HDR10 compatibility and 99% sRGB coverage round out the image features, but the stated 300 cd/m² brightness and 1000:1 contrast ratio set a more modest display profile than the Deco Gear VA panels’ listed 3000:1 contrast. Choose LG for USB-C charging and focused work, and skip it if gaming speed or a flat panel is a priority.
Pros:- USB-C delivers up to 90W to a compatible laptop.
- Built-in KVM and four USB ports support shared peripherals.
- 34-inch 3440 × 1440 IPS screen with 99% sRGB coverage.
- Reader Mode and Flicker Safe are included for long work sessions.
Cons:- 60Hz refresh rate and 5ms response time are less suited to fast-paced gaming than the 165Hz and 120Hz alternatives.
- Only one HDMI input is listed.
- OnScreen Control requires a separate software download for mouse-based adjustments.
Best for: People switching between a work laptop and another computer who want the strongest listed USB-C charging and a 34-inch work screen.
Not ideal for: High-refresh-rate gamers, buyers who need multiple HDMI inputs, or anyone who requires a flat display for precise alignment.
- Screen:34-inch curved IPS
- Resolution:3440 × 1440
- Refresh rate:60Hz
- Response time:5ms
- USB-C power delivery:Up to 90W
- KVM:Built-in
- Color coverage:99% sRGB
- Other features:HDR10, Reader Mode, Flicker Safe
Our verdict“I’d choose the LG for a work-centered two-computer desk where 90W USB-C charging matters more than gaming speed.”
34″ Ultrawide Monitor, 3440×1440 UWQHD 165Hz IPS Flat with USB-C KVM
This 34-inch Fast IPS model is the refresh-rate choice: it combines an integrated KVM with a 165Hz panel over DisplayPort. That makes it a better fit than the 60Hz LG for someone who shares a desk between work and gaming, while its 3440 × 1440 resolution and 21:9 format retain plenty of room for work windows. Its USB-C port offers 65W power delivery, and the built-in USB hub, KVM, and PBP/PIP support give two-device workflows more flexibility than a simple display input switch.
There are connection caveats to account for. The full 165Hz refresh rate is supported through DisplayPort, not HDMI, and FreeSync must be enabled in the on-screen menu. Its 65W USB-C charging is less than LG’s 90W, which may matter for a laptop that needs more power. Compared with either 49-inch Deco Gear, this screen takes up less desk width but has substantially less horizontal resolution and screen area. I’d put it first for a mixed-use setup that benefits from high refresh and color coverage; a laptop-first work desk may be better served by LG.
Pros:- 165Hz refresh rate over DisplayPort.
- Built-in KVM, USB hub, and USB-C with 65W power delivery.
- Fast IPS panel with 100% sRGB and 93% DCI-P3 coverage.
- PBP/PIP and FreeSync support.
Cons:- 165Hz is available through DisplayPort, not HDMI.
- FreeSync must be enabled manually in the on-screen menu.
- USB-C power delivery is 65W, below the LG’s listed 90W.
Best for: People who want one monitor for two-computer switching, productivity, and high-refresh gaming, with DisplayPort available for the gaming device.
Not ideal for: Laptop users who need more than 65W charging, or gamers whose device can connect only through HDMI at the highest refresh rate.
- Screen:34-inch flat Fast IPS
- Resolution:3440 × 1440
- Aspect ratio:21:9
- Refresh rate:Up to 165Hz via DisplayPort
- USB-C power delivery:65W
- KVM:Built-in
- Ports:USB-C, HDMI 2.0, DisplayPort 1.4, 2× USB-A, 1× USB-B
- Other features:FreeSync, PBP/PIP
Our verdict“I’d pick this 34-inch model for a two-computer desk where high-refresh gaming matters alongside KVM convenience.”
Deco Gear 49-Inch Curved Ultrawide Monitor
This Deco Gear takes the wide-screen route to multi-device work: its 49-inch, 5120 × 1440 display gives you the horizontal space of a dual-QHD setup, while the built-in KVM lets a shared keyboard and mouse serve two connected computers. It also lists USB-C with 65W power delivery, so a compatible laptop can connect and charge from the display. Among this group, it stands out for including built-in speakers and a stand with height, tilt, and swivel adjustment, which makes it the more self-contained of the two 49-inch options.
The 32:9 VA panel, 120Hz refresh rate, 1ms MPRT, and 3000:1 contrast ratio make it a broad all-purpose screen, but it asks more of the desk than either 34-inch monitor. Its listed connections include one HDMI 2.0 input, one DisplayPort, USB-C, two USB-A ports, and one USB-B port; the single HDMI connection may constrain a setup with several HDMI-only sources. The B0H1VFKC84 Deco Gear shares the key 49-inch display, refresh, contrast, and charging specifications and explicitly lists PIP/PBP support. Pick this model for its speakers and adjustable stand; consider the other Deco Gear if its listed split-screen features matter more to your workflow.
Pros:- 49-inch 5120 × 1440 screen provides a wide dual-QHD workspace.
- Built-in KVM and USB-C with 65W power delivery.
- 120Hz refresh rate, 1ms MPRT, and Adaptive Sync.
- Built-in speakers and height, tilt, and swivel stand adjustment are listed.
Cons:- The 32:9 screen requires substantial desk width.
- Only one HDMI input is listed.
- USB-C power delivery is 65W, below LG’s 90W.
Best for: People with room for a 49-inch curved screen who want built-in speakers, adjustable stand positioning, and a KVM for two computers.
Not ideal for: Small desks, users with multiple HDMI-only sources, or anyone who prefers a conventional 16:9 or 21:9 shape.
- Screen:49-inch curved VA, 1500R
- Resolution:5120 × 1440 (Dual QHD)
- Aspect ratio:32:9
- Refresh rate:120Hz
- Contrast ratio:3000:1
- USB-C power delivery:65W
- KVM:Integrated
- Other features:HDR400, built-in speakers, height/tilt/swivel stand
Our verdict“I’d choose this Deco Gear when a wide workspace, integrated speakers, and an adjustable stand matter more than compact dimensions.”
Deco Gear 49-Inch Curved Ultrawide Monitor with Dual QHD (5120×1440), HDR400, 120Hz, Adaptive Sync, 1ms MPRT, USB‑C 65W PD, KVM and PIP/PBP
This 49-inch Deco Gear is built around screen area and flexible layouts. Its 5120 × 1440 resolution across a 32:9 VA panel creates room for broad side-by-side work zones, and listed PIP/PBP support lets you view content from multiple sources at once. The KVM switch and USB-C with 65W power delivery address the other half of a multi-device desk: switching shared peripherals and connecting a compatible laptop with fewer cables. At 120Hz with Adaptive Sync and 1ms MPRT, it also has a higher refresh ceiling than the work-focused LG.
Its central tradeoff is size: the 49-inch curved screen can replace a pair of monitors, but it needs the desk width to do so comfortably. Compared with the 34-inch Fast IPS option, it offers far more workspace but not that model’s 165Hz refresh rate or IPS color gamut figures. The listed VA panel has 3000:1 contrast and 100% sRGB coverage; there are no built-in speakers, so plan on separate audio. The other Deco Gear 49-inch listing also offers 120Hz, 65W charging, and a built-in KVM, while specifying speakers and an adjustable stand. I’d choose this version when PIP/PBP is the deciding workflow feature and external audio is already part of the setup.
Pros:- 49-inch 5120 × 1440 display can replace a dual-monitor layout.
- Built-in KVM with USB-C power delivery up to 65W.
- PIP/PBP supports multi-source viewing.
- 120Hz refresh rate, Adaptive Sync, and 1ms MPRT.
Cons:- No built-in speakers are listed.
- Large 32:9 format needs significant desk space.
- USB-C power delivery is lower than LG’s 90W.
Best for: People with a large desk who want a 49-inch dual-QHD workspace, PIP/PBP viewing, and KVM switching between computers.
Not ideal for: Buyers with limited desk space, those who rely on integrated speakers, or users whose priority is a 165Hz gaming display.
- Screen:49-inch curved VA, 1500R
- Resolution:5120 × 1440 (Dual QHD)
- Aspect ratio:32:9
- Refresh rate:120Hz
- USB-C power delivery:65W
- KVM:Integrated
- Contrast and color:3000:1 contrast, 100% sRGB
- Other features:HDR400, Adaptive Sync, PIP/PBP
Our verdict“I’d choose this version for PIP/PBP and a broad workspace, provided the desk fits it and external audio is available.”
How We Picked
I ranked these monitors by how useful their built-in KVM is in a real two-computer setup, then weighed the surrounding features that affect daily use: USB-C power delivery, available ports, screen format, refresh rate, and picture-by-picture support. A KVM switch is most convenient when the monitor can also connect the computers and share peripherals cleanly, so I gave weight to USB-C charging and the listed USB hubs rather than treating the KVM label as sufficient on its own.
The order reflects different buyer priorities. LG leads for a work laptop because its listed 90W USB-C power delivery exceeds the 65W offered by the others, though its 60Hz refresh rate makes it less suited to fast gaming. The 34-inch Fast IPS model follows for users balancing productivity with high refresh gaming. The two 49-inch Deco Gear screens rank for buyers who value screen area most; their listed core display and KVM specifications are alike, while the B09VWHWYPJ listing adds speakers and an adjustable stand and the B0H1VFKC84 listing emphasizes PIP/PBP support. Product details here are based on the supplied specifications, so I avoid assuming unlisted capabilities.
| monitor with built in kvm | KVM | Other features |
|---|---|---|
| LG UltraWide QHD 34-Inch Curve | Built-in | HDR10, Reader Mode, Flicker Safe |
| 34" Ultrawide Monitor | Built-in | FreeSync, PBP/PIP |
| Deco Gear 49-Inch Curved Ultra | Integrated | HDR400, built-in speakers, height/tilt/swivel stand |
| Deco Gear 49-Inch Curved Ultra | Integrated | HDR400, Adaptive Sync, PIP/PBP |
Factors to Consider When Choosing Monitor With Built In Kvm
I’d choose a KVM monitor by matching its switching, charging, and screen layout to the computers I actually plan to connect. A KVM can share a keyboard and mouse between systems, but the cables and ports determine how convenient that arrangement is day to day.
Check what the KVM shares
Look at the monitor’s USB connections as well as its video inputs. A KVM needs a way to associate the shared keyboard and mouse with each computer; these picks list USB-A and USB-B connections or USB-C alongside their KVM feature. Confirm the cable arrangement required for your computers and peripherals before buying. PIP/PBP, listed on both Deco Gear B0H1VFKC84 and the 34-inch Fast IPS option, adds the ability to show multiple sources together. That is useful when you want to monitor two systems at once, while ordinary KVM switching is enough if you mainly alternate between them.
Match USB-C charging to your laptop
USB-C power delivery can reduce desk cables by carrying video, data, and power through a compatible connection. The LG lists 90W, while both Deco Gear models and the 34-inch Fast IPS option list 65W. Check the power needs of your laptop: a lower-wattage connection may charge more slowly or may not suit every system under load. If you use a desktop without USB-C charging, refresh rate, screen size, and the port combination may matter more.
Choose screen size for your desk and work
The two Deco Gear monitors offer 49 inches and 5120 × 1440 resolution in a 32:9 shape. That layout can replace two separate screens and reduce the gap between work areas, but the display needs ample width. The LG and Fast IPS picks use a 34-inch 3440 × 1440 21:9 format, offering ultrawide space in a less expansive footprint. I’d measure the desk and viewing distance before deciding that more screen area will be more comfortable.
Set priorities for gaming and image work
For fast games, the 34-inch Fast IPS model lists up to 165Hz through DisplayPort; the Deco Gear monitors list 120Hz, and the LG lists 60Hz. Keep the input limitation in mind: the 34-inch model does not support 165Hz through HDMI. For color-oriented work, compare the stated panel and gamut figures as well as your software and calibration needs. The Fast IPS model lists 93% DCI-P3, while LG lists 99% sRGB; the supplied Deco Gear details list 100% sRGB. Those figures describe different coverage ranges and do not alone determine which screen will suit a specific production workflow.
Compare the two 49-inch Deco Gear listings carefully
The supplied details show both Deco Gear models with 5120 × 1440 resolution, a VA panel, 120Hz refresh, 65W USB-C charging, and an integrated KVM. The B0VWHWYPJ listing specifies built-in speakers and a stand with height, tilt, and swivel adjustment, while B0H1VFKC84 explicitly lists PIP/PBP and says it has no built-in speakers. I’d base the choice on which listed detail matters to your setup, and verify the exact model and included features on its listing before purchase.
Frequently Asked Questions
What does a built-in KVM switch do in a monitor?
A built-in KVM switch lets you use one keyboard and mouse with more than one computer connected to the monitor. You switch the active computer through the monitor’s KVM controls, with the exact cable setup depending on its ports and the devices you connect. It can make a two-computer desk easier to manage, but check which USB connections and peripherals the monitor supports.
Can USB-C connect and charge a laptop while using the KVM?
It can when the monitor, laptop, and cable support the needed video, data, and power functions. In this group, the LG lists up to 90W USB-C power delivery, and the other three list 65W. Compare that figure with your laptop’s power requirements, and check whether the USB-C connection provides the data path your KVM setup needs.
Which of these monitors is best for gaming?
The 34-inch Fast IPS monitor is the refresh-rate pick, with up to 165Hz through DisplayPort. The two 49-inch Deco Gear models list 120Hz, while the LG lists 60Hz. If you connect the Fast IPS monitor over HDMI, its 165Hz mode is not available, so check the graphics device’s outputs and the monitor’s supported input modes.
Do the two Deco Gear 49-inch models offer the same features?
The supplied specifications overlap on the main display and KVM features: both list 5120 × 1440 resolution, 120Hz, a VA panel, 65W USB-C power delivery, and an integrated KVM. The B09VWHWYPJ listing specifies built-in speakers and an adjustable stand; the B0H1VFKC84 listing explicitly specifies PIP/PBP and no built-in speakers. Check the exact listing to confirm the feature set for the model you are considering.
Should I get a 34-inch or 49-inch monitor for two computers?
A 34-inch ultrawide is a practical fit for desks where you want extra workspace without giving over as much width. A 49-inch dual-QHD display gives you a broader area for simultaneous windows or a dual-monitor-style layout, but it needs more room. For two computers, also decide whether you need to see both sources at once through PIP/PBP or mainly want to switch the KVM between them.
Conclusion
I’d choose the LG 34WQ73A-B for a work laptop and a second computer when stronger USB-C charging is the priority. For a shared gaming and productivity desk, the 34-inch Fast IPS model brings the highest listed refresh rate, provided DisplayPort is available. If the goal is replacing two screens with one expansive display, I’d look at the 49-inch Deco Gear models: B09VWHWYPJ lists speakers and an adjustable stand, while B0H1VFKC84 lists PIP/PBP. Match the model to the space, connections, and way you want to switch between computers.
