ATEN and UGREEN make KVM switches that let one keyboard and mouse control more than one computer, but their product ranges suit different desks. ATEN covers more connection types and specialist setups, while UGREEN focuses on straightforward switches for sharing a monitor and USB accessories. For Black Friday 2026, the right choice depends on your display, computer ports and how many devices you need to connect.
I researched and compared specs, reviews and owner feedback to identify useful picks across both brands. My pick for most people is a 2-port HDMI model with 4K at 60Hz support, provided both computers and the display have compatible HDMI connections. Check the full model specifications before buying: KVM switches differ in video standards, USB speeds, included cables and supported resolutions.

Is ATEN or UGREEN better for a 2-computer desk?
ATEN and UGREEN both offer 2-computer KVM switches, but ATEN provides more variety in display connections and setup types. ATEN CS22U supports VGA, ATEN CS1922M uses DisplayPort, and ATEN CS1822 serves HDMI users who need 4K at 60Hz. UGREEN's featured models focus on HDMI and one shared monitor.
For a simple desk, compare the UGREEN 2-Port HDMI KVM Switch 4K 60Hz with 4 USB 3.0 Ports against ATEN CS1822. Both target HDMI setups, while the UGREEN model lists 4 USB 3.0 ports. For dual displays or a DisplayPort-based workstation, ATEN has the clearer fit among these picks. Choose by the equipment already on the desk, not by brand alone.
Which KVM switch works with a 4K monitor?
ATEN CS1822, ATEN CS1922M and UGREEN 2-Port HDMI KVM Switch 4K 60Hz with 4 USB 3.0 Ports support 4K at 60Hz when the connected computer, switch, cables and monitor all support the required signal. ATEN CS22H also lists 4K support, so check its exact refresh-rate details against the display.
A resolution label by itself does not guarantee the refresh rate, HDR features or other display functions you need. Check the product specification for the exact model and confirm that both computers output the same video connection the switch accepts. An 8K-rated switch is only useful when the rest of the setup supports 8K.
When is a DisplayPort KVM better than an HDMI KVM?
ATEN CS1922M and ATEN CS1942DP are better fits than HDMI models when a workstation uses DisplayPort monitors and compatible computer outputs. ATEN CS1922M supports one DisplayPort display, while ATEN CS1942DP is designed for a dual-view setup with 2 monitors.
A connection mismatch is a decisive reason to skip a model: HDMI plugs do not connect directly to DisplayPort ports without suitable conversion equipment. Check the number of video outputs on each computer, the number of displays you need to share and the required resolution. UGREEN's selected models suit HDMI, not a DisplayPort-only desk.
What should you know about KVM USB ports?
UGREEN 2-Port HDMI KVM Switch models with 4 USB 3.0 ports suit desks that share a keyboard, mouse and additional accessories between 2 computers. ATEN CS1822 and ATEN CS1922M also list USB 3.0, while the compact ATEN CS22U and ATEN CS22H are simpler cable-style options.
USB ports on a KVM are for sharing connected peripherals, not for adding video connections. Check the switch's USB standard and the power or bandwidth needs of devices such as storage drives, webcams and audio equipment. Plug high-demand gear directly into a computer when the switch's specifications do not cover the device's requirements.
Buying Guide
1. Match the video connection
Choose HDMI, DisplayPort or VGA based on the ports on both computers and the monitor. ATEN CS22U suits VGA equipment; UGREEN's listed switches are HDMI options. A physical port match avoids extra adapters.
2. Confirm resolution and refresh rate
Match the KVM's exact resolution and refresh-rate support to the monitor. A 4K at 60Hz setup calls for a model that lists both figures, such as ATEN CS1822 or UGREEN's 4K 60Hz switch.
3. Count displays and computers
The selected products connect 2 computers, but ATEN CS1942DP supports a dual-display workflow. Count the displays and video outputs each computer needs before settling on a single-monitor KVM.
4. Count shared USB devices
List every keyboard, mouse and accessory that needs to move between computers. UGREEN's featured HDMI models list 4 USB 3.0 ports. Confirm port count and device requirements on the exact product listing.
