How we scored them
The Office Score weighs performance, build, value, safety and warranty. For KVM switches, safety means stated certifications and switching that cannot mix inputs; only one pick states a certification. Three of the five picks state a warranty term. How we pick explains the weights.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| IOGEAR GCS22U KVM Switch | 9.6 | 30 | 21 | 20 | 0 | 4 |

| TCRAYCH 2-Port KVM Switch | 9.4 | 28 | 19 | 21 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best kvm switch vga
Count the computers first
Most desks need 2 ports, and four of the five picks here switch exactly two computers. The MT-VIKI is the exception with 4 ports plus a 3-port USB hub, so it suits a desk that may grow a third or fourth machine. If two is plenty, the 2-computer KVM switches roundup has more options. The 3-port USB hub on the MT-VIKI also shares a printer or drive across all four machines, which the 2-port picks cannot do.
Check the resolution against the monitor
Both IOGEAR picks list 2048 x 1536, the highest resolution stated here, while the other three list 1920 x 1440. Match the switch to the monitor: a 1920 x 1440 switch will not show more than its stated maximum. If the monitor takes HDMI instead, see the KVM switches with HDMI roundup. Compatibility runs downward too: the listings note backward compatibility with lower resolutions, so a higher-rated switch still drives a smaller monitor.
Pick the switching method
The GCS22U switches from a wired remote button on a 6 ft cable, the DGODRT from a wired desktop controller, and the GCS72U, MT-VIKI and TCRAYCH from buttons on the unit itself. A remote or controller keeps the switch box tucked away; a panel button keeps everything in one small box. None of the five list keyboard hotkey switching.
Audio is rare here
Only the IOGEAR GCS72U lists audio switching, with 2.1 stereo output and microphone support alongside its 2048 x 1536 video. The other four move video, keyboard and mouse only. If the desk shares speakers between machines, the GCS72U is the only pick here that carries sound.
Mind the cables and power
Every pick includes its KVM cables: molded-in 3 ft cables on the GCS72U, included sets on the rest, and 4 cables with the MT-VIKI. The GCS22U, GCS72U and TCRAYCH state that no power adapter is required, and the MT-VIKI draws power through its USB connector. Fewer wall warts means a cleaner desk. The listings that state a cable length keep it short: 3 ft molded-in on the GCS72U and a 6 ft remote cable on the GCS22U.
| If you need | Look for | Example pick |
|---|---|---|
| Highest resolution | 2048 x 1536 stated | IOGEAR GCS22U, GCS72U |
| Four computers | 4 ports and a USB hub | MT-VIKI |
| Switch from your chair | Wired remote or controller | IOGEAR GCS22U, DGODRT |
| Audio too | Stated audio and mic support | IOGEAR GCS72U |
Setup Notes
- Measure cable runs: the GCS72U includes 3 ft molded-in cables and the GCS22U a 6 ft remote cable, so plan the desk layout around the shortest run.
- Confirm VGA ports on every computer before ordering; each pick here is VGA in and VGA out.
- Plug the USB head in too: on combo cables the USB connector carries power and data.
- Place the switch where its button or remote is reachable; the TCRAYCH switches on its panel.
- Label each KVM cable at the computer end, so a re-plug after moving the desk goes to the right machine.
- Keep the remote or controller on the desk: the GCS22U remote rides a 6 ft cable and the DGODRT controller is wired, so both need a cable path back to the switch.

Yes on all five. The GCS72U has 3 ft molded-in cables, the GCS22U lists included cables, the MT-VIKI includes 4 KVM cables, and the TCRAYCH and DGODRT each include 2 KVM cables.
Do these need a power adapter?
The GCS22U, GCS72U and TCRAYCH state that no power adapter is required. The MT-VIKI draws power through its USB connector, so plug the USB head in.
