Review on CKL KVM Switch Dual Monitor DisplayPort 4 Port 4K 60Hz 4:4:4 by Jessie Burgos

Part number: CKL-623DP sold by Revain.com Services LLC for $389. Unfortunately I am returning this unit after losing several nights of sleep trying to troubleshoot this unit. I have a custom built gaming PC and a Lenovo laptop in a docking station for work. For the past few years, I've hooked them up to a three-monitor system, with two 2160p60 displays flanked by a 1080p240 screen. To switch between them, I had to manually switch two monitors. - Ported StarTech Dual Screen KVM for 4K displays and switched the center screen between HDMI (laptop) and DisplayPort and then finally switched the USB 3.0 switch for my peripherals. I was hoping that this KVM from CKL would allow me to put all three screens on one KVM, no less with a wired remote, handle and y peripherals. Unfortunately, I've never been able to get my average monitor to wake from sleep mode, no matter what cables, port combos, or connections I use. My side monitors worked, but only at 1440p60, with one of the two constantly flickering. I made sure all the cables were ok and there were no issues connecting directly or using the old KVM. I've also tried multiple power supplies, rearranged ports and cables, bought different adapters, and even bought a portable monitor to test. Probably 2/3 of the time I couldn't show anything at all. Definitely not worth the price.
