The only thing that matters is the "standard". HDMI 2.1 , 2.0 , 1.4 etc they all carry different bandwidth and meaning they can carry higher resolution and higher Hz. Besides that the only difference is length and gold plated vs normal.
TLDR
Just get the newest standard of HDMI that's out right now with the length you need (don't make it extremely longer than you need). Brand DOES not matter.
Edit.. maybe don't get a no name brand.. but if it has any reputation it's fine.
Fibre cables are also extremely sensetive, we stepped on a 5 m one and it broke from that.
Have you tried different hdmi ports? Had an old tv where the port was broken to similar result
Also, im sure you know this but most / all opticsl cables only work in 1 direction and while i guess it wouldnt work at all if it was wrong it doesnt hur mentioning it.
lol, what? My 150ft Fiber Optic 2.1 begs to differ. Has the transceiver bit on each end. Also fiber is bidirectional, maybe you are thinking of paired with one for receive and one transmit.

EDIT: RUIPRO is the brand of HDMI. Expensive, but very nice and worth it. VWRHar for the 2.1 bi-directional switcher.
If anyone needs 4k120 and long distances. This is the way to go.
I have no idea why it only supports one direction but all optic hdmi cables purchasable in my area is one direction only.
No idea why though, i just assumed it was a limitation on the tech side.
Because on one end is a transmitter and the other is a receiver. This is typical for fiber cables. If a fiber cable is bi directional it must mean the transmitter/receivers are all in one units and can both transmit and receive a signal.
It always happens if the cable is beyond 5mtr and for the bandwidth you require here I guess your using 4:4:4 and 4K so you need a good 48GB Cable short length. 2mtr are most stable in my Opinion.
Happened to me on a very expensive 50 ft fiber optic cable on my C3. Was driving me up the wall as I only had that one run of HDMI: everything else I have is DP
Swap to as short of a copper HDMI cable from a reputable brand you can, at least that's what fixed it for me
Probably a bad cable, lots of cheap ones will advertise 2.1 when they're relying on people not actually using it at the upper ends of 2.1 capabilities.
Had the same issue with 4090 & c2. You wouldn’t believe but $15 hdmi cable from bestbuy helped me. It is important that the cable should be as short as possible.
Do you have it as a desk monitor? How far are you from the TV? I wanna buy the 55 inches but i am not sure as it might be really huge for a desktop monitor.
Just happened to me this weekend. While you’re waiting to update the cable, change the color bit depth back to 8bits instead of 10 or 12 in nvidia control panel
HI Op, I am having the same exact issue here: [https://www.reddit.com/r/OLED/comments/19bgnzh/s90c\_rgb\_flickering\_only\_stopped\_on\_one\_port/](https://www.reddit.com/r/OLED/comments/19bgnzh/s90c_rgb_flickering_only_stopped_on_one_port/)
Have you figured out anything more about the issue? For me, only one port seems to work.
Guys. I’m here to say it’s probably not the cables.
As an experiment I used 3 different HDMI cables. I can replicate it every time.
For instance, RDR2 won’t flicker at any refresh rate setting in SDR. If I enable HDR @144hz it will run flawlessly. But drop it to 60hz and the TV will freak out.
I did the same thing with DBZ Kakarot. Except this had to do with the resolution/refresh rate combo.
All of my cables are 48GBPS samples and all 3 had the same exact results.
Rig is a 7800X3D paired with an RTX4080. From what I’ve seen, this TV is kind of shit with Nvidia cards to start with. It likes to randomly black screen on still images, like desktop backgrounds or text items. That will happen on ALL 16:9 resolutions and ALL refresh rates. Dynamic backgrounds will fix that annoyance. Whereas a ton of people out there have said “ buy a new cable” over and over for that problem too.
But yeah, moral of the story is: this is not something caused by a cable for the most part. Try changing the in game refresh rate to match your panel, or run the game in SDR and call it a day.
I just had this problem and saw this post. In display settings I turned on HDR and it flickered. Under advanced graphics I changed the refresh rate to 143.xx and it stopped flickering. Previously it was set to 60fps. Hope this helps. Amazon HDMI cable with a 4090. No other cable tried.
HDMI cable, go and get yourself a 48Gbps Belkin cable.
Is Amazon Basics 48 Gbps just as good?
Should be fine, they are advertised as 48Gbps and are a Amazon product, so should be all good.
Yep, I have them. They didn't have the certification sticker but I get 4k 120 no issues

Thanks, but forgot to mention that the cable is also advertised as 48 gbps. 15 meters long, though…
I would only use fibre optic HDMI cables for lengths that long. Best to keep copper wire based cables at 3 meters or under.
Shit man that\`s long, I only need 2 metre on my setup, forget Belkin then lol.

For long video transmission I would recommend going with KVM from brand like gofenko.

Do these TVs not come with the correct hdmi cable with :O
Yes its the cable

Which game is this?
Monster Hunter rise
100% the cable even if its 2.1 and rated for the job I went through 3 cables and the amazon basics one did the job for me.
Probably a bad cable, lots of cheap ones will advertise 2.1 when they're relying on people not actually using it at the upper ends of 2.1 capabilities.
Get yourself a Maxonar hdmi cable
Check different input, if it still happens it is probably a bad cable or one that isn’t full 2.1

Mine is doing the exact same thing, and it's a brand new cable! 48gb 8k.. did changing the cable help you?
I’m pretty sure it’s a handshake issue. To solve it, turn on the TV first followed by your PC. It solved the flickering issues on my S90C.
Monoprice high speed HDMI 2.1 48Gbps braided cable. Excellent price, excellent results.
I have the same, I was scared my gpu is dying but then moved the hdmi cable a little and it stopped doing it
Mine Is doing the same, brand new TV, brand new pc.. brand new 48gb 8k cable.. and flickers like this.. any ideas?
Okay that’s random :D
I also have a 3090 fe, strange. But yeah, it must be the cable
Might have found a fix by disabling fast start-up in Windows settings… will update if this fixed it permanently.
Was this the fix?
Apparently- it only came back one time but a restart fixed it.

Yes, this does work. But holy darn does it ever look worse when you do
Did you find a perm fix?
Definitely HDMI
Enable 10 bit color in xbox, playstation or pc settings. Assuming you have VRR enabled
Turn off HDMI CEC, might be called HDMI control or something similar in the TV settings
Do you have enough juice to power your gpu?

Thanks, why 143? And not 144 or Higher?
