I’m interested in buying this active adapter from Club3D https://www.jimms.fi/fi/Product/Show/163613/cac-1085/club-3d-displayport-1_4-hdmi-2_1-aktiivinen-adapteri-musta
I have a RTX 2080 Super and LG C9. I want to be able to output 4K 120Hz to my OLED but my GPU’s HDMI output is only 2.0b. I’ve heard this adapter cannot support HDR alongside Variable Refresh Rate but that’s a compromise I’m willing to swallow.
I watched this video though: https://youtu.be/C8Hg3eq1izM and heard the signal becomes more or less non-existant if the cable is long after the adapter (3 meter and up doesn’t work apparently) mentioned around the 8:20 mark in the video.
What I’m curious about, as there’s 5 meters between my PC and TV, can I buy myself a 5 meter DisplayPort 1.4 cable (male x female) between the GPU’s output and the adapter’s input, hook the adapter to leech power off my TV’s USB port, then attach, say, a short 0.5m HDMI 2.1 (male x male) cable between the adapter and TV and get it to work?
That way the length of the cable would come before the adapter; instead of after. I’d lean towards “Yes, it will work”, but it seems like a relatively expensive endeavour just to test with.
Thanks for any answers I may get upfront!
