Specifications are manufacturer rated as listed, collected 23 October 2026. Two of the five state a warranty term.
How we scored them
The Office Score weighs performance (stated resolution, USB speed and port count, and switching options), build (housing material, size and included cables), value for the stated specs, safety and warranty. For a KVM switch, safety would mean stated overcurrent, ESD or surge protection on the listing; none of the five listings names any, so no safety points were given. Two listings state a warranty term: CMSTEDCD at 2 years and Hearvo with a lifetime Protection Plan. How we pick explains the weights.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| CMSTEDCD 8K KVM Switch | 9.7 | 32 | 22 | 20 | n/a | 3 |

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. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
How to choose the best kvm switch for 4 computers
Start with the resolution you actually run
Match the switch to the monitor. The CMSTEDCD lists 8K@60Hz and 4K@120Hz on HDMI 2.1, the Hearvo and PVBCTCSID list 4K@60Hz, the DGODRT lists 4K@30Hz, and the VGA model tops out at 1920×1440. The CMSTEDCD notes that computers, monitor and cables must all support 8K or 4K120Hz to reach it. Check the monitor’s own spec first, then buy the switch that matches it. Dual-monitor desks should look at the More picks instead: both ATLAHET models run 4 computers to 2 monitors at up to 8K@60Hz with extend and duplicate modes.
Count the USB ports and their speed
Three of the five list 4 USB ports at up to 5Gbps: the CMSTEDCD, the Hearvo and the PVBCTCSID. The Hearvo splits its four into 3 USB-A and 1 USB-C, which suits a newer laptop dock setup. The two DGODRT models list 3 USB devices each, and the VGA one is USB 2.0. If the printer, webcam and headset all need a home, count devices before you buy, and pair the switch with the keyboards and mice and mouse pads guides.
| KVM Switch | Resolution | USB | Warranty |
|---|---|---|---|
| CMSTEDCD 8K KVM Switch | 8K@60Hz, 4K@120Hz | 4 x USB 3.0 | 2 year |
| Hearvo S7415H KVM Switch | 4K@60Hz | 3 USB-A + 1 USB-C | Lifetime Protection Plan |
| PVBCTCSID 4K KVM Switch | 4K@60Hz | 4 x USB 3.0 | Not stated |
| DGODRT 4K@30Hz KVM Switch | 4K@30Hz | 3 USB devices | Not stated |
| DGODRT VGA KVM Switch | 1920×1440 | 3 x USB 2.0 | Not stated |
Check what is in the box
Cables decide the real setup cost. The two DGODRT models include 4 2-in-1 KVM cables each, the Hearvo includes 4 USB cables and 1 HDMI cable, and the CMSTEDCD and PVBCTCSID include 4 USB cables each plus power adapters. The CMSTEDCD box also holds a 12V1A power supply and an after-sales card.
Switching style and desk placement
Every pick switches by panel button and ships with a remote or desktop controller, so the box can sit behind the monitors. The PVBCTCSID notes hotkey switching is not supported, so plan on the remote or the buttons. The CMSTEDCD, Hearvo and PVBCTCSID list EDID support to keep display settings stable when switching computers.
Read the warranty line
Two of the five state a warranty term: CMSTEDCD lists a 2-year term and Hearvo includes a lifetime Protection Plan card. The other three state no warranty term. A KVM switch is a box of ports and cables, so a stated term is worth more than a vague service promise.
Frequently Asked Questions
Do I need a KVM switch for 4 computers?
If one keyboard, mouse and monitor must serve four machines, yes. A 4-port KVM like these five switches the shared set between all four computers without replugging cables.
What resolution do I need on a KVM switch?
Match the monitor. These five span 1920×1440 on the VGA model to 8K@60Hz on the CMSTEDCD, with 4K@30Hz and 4K@60Hz in between.
Do KVM switches need external power?
Some do. The CMSTEDCD and PVBCTCSID include power adapters, while the two DGODRT models state no external power supply is required. The Hearvo listing names no power adapter.
Can I use a KVM switch with a laptop?
Yes. The DGODRT listings name laptops as compatible devices, and the CMSTEDCD notes all four computers need HDMI ports. Check the ports on each machine first.
What is EDID on a KVM switch?
EDID lets the switch report the monitor’s settings to each computer so windows do not rearrange when you switch. The CMSTEDCD, Hearvo and PVBCTCSID list EDID support.
Can a KVM switch run two monitors?
The five main picks are single-monitor switches. For two monitors, the More picks list two ATLAHET dual-monitor models with extend and duplicate modes.
