Review on 🔌 Monoprice 114196 HDMI High Speed Active Cable - 15 Feet - Black, 4K@60Hz, 18Gbps, HDR, 36AWG, YUV 4:4:4 - Ultra Slim Active Series: Superior 4K Video & Audio Transmission! by Erica Shine

Bought this cable for my 4K projector that my computer is connected to. I found that the cable only supports 4K @ 30Hz with RGB. In the Nvidia control panel, if you set the refresh rate above 30Hz with the default settings, no image is displayed. Setting the digital format to YCbCr 4:2:0 allows 4k@60hz but loses the ability to enable HDR. Other formats are locked at 30Hz with no ability to enable HDR. At first I thought it was a limitation of my GPU/cable, so I bought a 15ft RevainBasics CL3 4K cable just to be sure. Revain supports 4K@60Hz with HDR enabled, so I can only conclude that this cable doesn't support true 4K@60Hz, at least with RGB/YcbCr4:4:4. You can get by with movies just fine, but if you're used to gaming at 60Hz and higher, you'll notice lag.
