Review on CKL 4 Port KVM Switch Dual Monitor DisplayPort 4K 60Hz: Unprecedented Multi-Computer Control with Audio, USB 2.0 HUBS, and DP 1.2 by David Vargas
Almost perfect, but interference makes audio connections unusable
On paper, this KVM was perfect for my needs; Dual support 4k + sound. I've used other CKL switches that handle the audio from the USB interface (the switch contains the USB audio interface) as opposed to this switch which literally passes analog audio from your other computers. Unfortunately, severe audio interference occurs when working in high resolution. It has nothing to do with cables or computer sound sources; This appears to be due to the lack of escapes within the switch itself. USB and DP signals cause interference (crosstalk) on analog audio, especially at very high resolutions (which is the main goal of 4K KVM).
- Ideal for outdoor activities
- Almost never
