Worked as expected
great price

Great video quality using this Fiber Optic HDMI 100? cable with my Sony VPL-XV7000ES projector.

Wanted to play desktop games on my TV, without moving PC from my Office. I have been waiting for a HDMI 2.1 graphics card for 6 months, and once I was able to order a card, I ordered this cable. At first I thought it wasn't working, until I went into the settings on the Q90T and enabled 'Input Plus' under 'External Devices' on HDMI Input 4 (only HDMI 2.1 input on the Q90T). Screen flickered, as the GPU automatically changed to 4K 120hz. I haven't tested VRR yet, but HDR 10bit and full sound appears to work. I don't have a way to test eARC+HDMI2.1 so I can't confirm it will work, but based on how well this cable is working now, I have no doubts.

I also tested it with my PlayStation 5, and all features are also listed as supported and available, although I don't yet have a game that does 4K 120hz.
