Hi all

I'm trying to sort out a proper connection from my 3090 (Display Port) to my TV (HDMI) but so far I've tried 2 adapters and neither were up to the job. GPU only has 1 HDMI out and that's used by my main monitor.

It's a 4m cable distance and I haven't been able to find a cable of similar length that will convert which is why I'm trying the adapter route instead.

Needs to support at least 4K HDR@60hz.

First adapter I tried would only support 4K@30 so sent that back.

Second one I tried produced a picture at 60hz, but with HDR enabled it was just a garbled mess so completely useless and now having to send that back too.

Close to giving up.

Anyone got any recommendations?
 
Main monitor is an OLED TV and only has hdmi inputs.

But would it be better then to use a DP to Hdmi converter cable to the main monitor thus freeing up the hdmi GPU output for the other TV then? It would mean I could get a much shorter cable for that screen so easier to get ahold of at least.

I guess my main concern is not causing any signal degradation or quality loss to main monitor by using a converter cable as that's where most of the magic happens. Is that a concern or should be fine?

Thanks all

Seems some mistakes being made here and why the issues. I use the following on my 3090 and works great to the TV in the living room with a 20M active fibre optic HDMI 2.1 cable below and the DisplayPort 1.4 to HDMI 2.1 adapter.

The converter you will need is named (google it) :-

Cable Matters 8K DisplayPort 1.4 to HDMI Adapter with 4K@120Hz or 8K@60hz, Unidirectional (DP 1.4) Display Port to HDMI port 8K Cable Adapter in Black, Support for RTX 3080/3090, RX 6800/6900 and More​


The HDMI cable you need is (google it) and get the length you need and remember these are directional when you wire it up :-

FIBBR 8K HDMI Fiber Optic Cable 20M, 48Gbps 8K HDMI 2.1 Cable/AOC Support 8K@60Hz, 4K@120Hz/144Hz HDR eARC Dolby Atmos HDCP 2.2&2.3 Compatible with PS5, Xbox Series X, PC, TV​



Both items you will find at the same store, when you google the names of them.

Hey thanks very much for these suggestions. I've ordered the suggested adapter and will see if that solves it. If not I'll order the cable you suggested too!
