I have this cable hooked up to my PC and finally bought an Nvidia RTX3080 to hook up to my LG G1 and the best I can get is 2560x1440 at 120fps or 4k 10bit color at 60fps. This could possibly be down to a configuration issue but I haven't had time to explore that yet.

The connection with my OLED CX with 4k/60 HZ is better, motion is imoroved, and switching programs is almost immediate. Highly recommended.

Does not support 4K120 nor HDR or VRR, at least as confirmed after checking with Monoprice Support. I could only get this cable to work at 4K60. And yes, all other devices in my setup support those features, I have everything working now (4K120 HDR G-Sync) with another brand's fiber cable.

I purchased this cable awhile back in anticipation of Nvidia's RTX3000 series of GPUs. After finally getting a chance to truly test it out, it's given me nothing but trouble. Setting my monitor to 4k/120Hz causes the screen to flash black. Eventually, the signal is dropped entirely. Same deal if I try to enable 10-bit color or G-Sync. My only recourse is to unplug the cable, plug it back in, and quickly set the display back to 60Hz and 8-bit color before the signal crashes out on me again.

It's possible there is some other underlying hardware issue going on that I'm unaware of, and if that's the case, I'll revise my rating. But for the time being, I kind of feel like a sap for spending a considerable sum of money on an HDMI cable that works no differently than any of the free ones I've acquired over the years.

Although a little pricey, they're sure worth it. For the length of run I needed, I still get great color and sound. HDR also is quite noticeable with these cable compared to other brands.
