Getting 4k HDR signal to my LG C8 TV

[Edgar_S]

Hey guys,

 

so, what would be the best way to get a high quality, high refresh rate HDR signal from my computer (running 2080Ti) to my 4k OLED TV with minimal input lag? My googleing skills are failing me here, i dont see a good widely adopted solution here. Help!

An HDMI-cable.

Lovely, thank you. I lacked that piece of sarcasm. I am not aware of any HDMI cables that car get 4k HDR signal at 100Hz any further than 2-3 meters. I need it to go at least 8 meters.

It's not a 100hz tv. It's a 60 or 50hz panel with motion smoothing that gets advertised as twice the refresh rate then. So quite frankly any semi decent hdmi cable will do.

Maybe you should have mentioned such details in your post then? You were only asking how to get a 4K HDR-signal to your TV, to which I replied ackordingly.

 

If you need a long HDMI-cable, you should look into active HDMI-cables, that get extra power from a wall-wart or a USB-port in order to maintain signal-quality over longer distance.

No, the LG C8 is actually a 120hz display, theoretically even capable of 4k@120hz.

However no current graphics card supports hdmi 2.1 so all you can do is either 4k60 or 1440p120 but in both cases a standard HDMI cable should do the trick. 

I'm not sure if 8 meters Is that much of a problem here. My brother runs a 10m cable to his 4k TV just fine. No HDR though.

My bad. Seems I found the wrong information then.

Indeed.

HDMI 2.1 is required for 4k 120hz, so cant be done currently due to there being no GPU's with HDMI 2.1

ALSO, the C8 uses HDMI 2.0 anyway so cant do 4k 120hz.

 

It does have a 120hz capable panel however and can do 1080p 120hz via HDMI 2.0.

As of right now i no not believe the C8 can do 1440p 120hz.

 

If u want 4k 120hz u may want to consider either buying a newer C9, or wait for the smaller but newer CX 48" to release sometime this year.

It will have added gaming features and is directed towards gamers.

It will support 4k 120hz via HDMI 2.1 (so ull need a newer 2020 GPU when they release that has HDMI 2.1), and has VRR and BFI along with low input latency ~ 5ms.

Went for a optical hybrid hdmi for now that enables all hdmi 2.0 features at 20m plus. Getting 4k @60hz with HDR (18Gb link)
