I would just "move the damned box closer" and use a shorter, good quality cable.
Troubleshooting an HDMI Problem with a Gaming PC
I decided to experiment with sending my PC game signal to my wall-mounted Sony HDR 4k TV in another room. My TV is, I believe, a Sony XBR 850. This was only really ever intended for use console gaming and this TV hit the sweet spot in terms of price when I bought it 2 years ago...HDR, thin so it wall mounts nicely (its edge lit but still had impressed reviewers with its black levels) and most of all it did great with gaming at 4k with HDR turnef on or off, with low input lag running in game mode. Its only negative was about 500 nits on the HDR brightness.....so punchy but not the bright you'd get with a real backlit HDR set.
I digress. When I send the signal from my 1080 Ti over that lengthy 30 foot HDMI cable, I get a great 4k/60 picture. Ok so...why the post!?
If I use the 2 ports that are enhanced (aka: HDR enabled for 18gpbs) I get no signal at all.
Windows sees the TV. It sees its HDR enabled and will allow me to turn the feature on in Windows.
But I get nothing on the screen, nada, zilch, not even a glitched image.
But as soon as I plug the cable into one of the regular HDMI ports that are not enhanced, I get a perfectly usable 4k/60 image....just no HDR
What are we thinking guys....HDMI cable just a bit too long to deal with 18gpbs but ok to deal with 10gb 4k/60? Think one of those fiber optic cables will provde less resistance? Thing that sucks there is....that's $80 bucks just to turn on HDR. Or...I could just move the damned box closer, I gotta say I hate being "so close"
I even forced HDR 10 on while playing Forza Horizon 4....the colors looked electric but I knew I was cheating....at least I don't think it's supposed to look quite that cartoony (this is forcing HDR on in the TV so it's doing, I guess, some sort of tone mapping on its own regardless of the signal being passed?).....
Anyhow thanks for the read.

Move the box closer just to test the if the issue is actually the cable, just make sure you have a short, genuine certified 2.0 cable. A 6' one can be had for $7. This won't make you feel better about price but it's good reference data: https://www.avsforum.com/forum/168-...operly-reliably-support-18gbps-hdmi-2-0b.htmlWhat are we thinking guys....HDMI cable just a bit too long to deal with 18gpbs but ok to deal with 10gb 4k/60?

I have similar weird issues with my PC and my LG C9. If I set an input on the C9 to HDR enabled, I cannot get any picture (just black screen). If I set it to standard, then the desktop will display and I can get HDR (both Windows and the C9 will then display HDR enabled) 15m of HDMI cable in my case.
Thanks for the reply.
Indeed, when I turn off the HDR Enhancement on my 2 "active, enhanced" HDMI ports I get a perfectly good 4k/60 picture, but windows doesn't see this as an HDR enabled display when I do that. I basically said "why am I agonizing over this" and gave up Windows 10 HDR = mockery in almost every post I read on the subject, I decided it wasn't worth my time.
My Sony display is edge-lit, so the HDR impact is somewhat minimal. As an example: With HDR turned on with my Xbox X, playing Ghost Recon Wildlands.....which is HDR enabled....I get a more washed-out image (as the backlight is maxed) and then I see things like headlights and spotlights look brighter, the sky becomes brighter and sunlight is brighter...but I'm basically getting white crush.
If I dial down the gamma/black/white levels, I'm left with an even less impressive HDR result. Translated: My display does HDR, but it just makes lightning-flashes and headlights stand out I watch zero movies on this display so I can't comment on anything but gaming.
I can force an HDR mode on the TV, and then games like Forza Horizon 4 take on a truly impressive level of color pop, but its artificial...I mean its not clipping, it's not ugly to look at, but it's clearly cartoonish. My solution? Set my backlight to 25 out of 50, set my gamma to a notch down, set my black levels a few notches down and then push color from 50 to 55.....good enough for me, poppy colors without the washed-out look of a 100% backlight.
If there's another way to go about this, and I'm sure there is, I haven't stumbled upon it yet but in the end I decided this was pretty much good enough for me for now.
