4K @120hz HDR/VRR

I have been reading the last couple of days that some tvs are struggling with those settings, and that the LG OLEDS are having a problem with the gamma too.

I have a 2020 Samsung Q80T, and apparently those are having display problems also. But on the other hand, I have read about people on 2020 LG nanocells that don't have problems and people with 2020 sony tvs also saying that everything is fine.

I will be picking up my console in a couple of hours and will report back my findings. But if anyone else is having problems or not, please post them.

Yeah it is quite depressing. TV manufactures just can't get it working well.



Sonys x900h (xh900x in europe) 120Hz mode seems to be there for PS5, so it seems they ignored the HDMI 2.1 specification just to get it working. But it should be updated in the next few month ... well I guess this means years or never.

I have an Oled 65E9....anyone having problems with this model? Ain't no way I'll buy a new TV soon.
 
I have a CX and a series x. I set it up with 4k@120hz enabled in the menu and activated VRR.

I only tried Sekiro so far and there are 0 issues with VRR. I did get a firmware update today that was supposed to fix some issues though.

I think with my Q70R I'm going to have to make due with 4K/60 with HDR..
I can live with that. It can do 120 at 1440P so I have options I suppose.

Just checked for an update on my c9, but nothing. although it does have auto-updates set up so it may have already pulled it.

Same set I use for gaming and I'm not massively fussed about 4k/120hz for now since so few games will actually support it and there's no current GPU on the market that can drive that framerate at that resolution in modern games with all the eyecandy turned up.

1440p/120hz is a perfectly fine compromise for me at the moment, especially at normal distances from the screen.

VRR fucks with the near black gamma values on 2019/2020 OLEDs. Best case you "just" get washed out blacks, worst case you get flickering parts on the screen. This gets worse the lower the VRR has to regulate the HZ. So ironically now you need higher fps to have a stable/good image which is exactly what VRR was supposed to fix to get around VSYNC.

VRR is fucked on all 2019 and 2020 OLEDs because LGs panels which all manufacturers use are at fault.
LG CX series has VRR issues with gamma which cannot be fixed, Sony Xh 90 has 4K@120 FPS issues with resolution which cannot be fixed etc etc. It's to early to jump onto the Hdmi 2.1 TV wagon.

Note quite, the higher end 2020 Samsungs also can work with 4K 120Hz HDR FreeSync/VRR, tested it with my XSX and Q950TS.
Sounds good. Although my tv is the one below yours. I am just about to get my XsX now

New firmware updates for Samsung TVs it seems.
[/QUOTE]
In Europe, when I checked this morning, the latest firmware was 1403.1. My tv has it installed. Is there a new one? If so, what is the number please?

The X900H I have apparently has issues with blurriness at 4K120, though I believe Sony is working on an update per some customer services responses posted on AVS forums.

I don’t really care personally as 120fps and the other HDMI 2.1 stuff didn't really factor into my purchasing decision. The X900H was just the best sub (barely) $1K 65” TV I could find after some research based on black levels, input lag, and no image retention risk as a paranoid person who regularly has ESPN on all day, games for hours on end etc.

I mostly play cinematic, single-player console games and opt for graphics over performance most of the time so I won’t be playing many things that offer 120fps anyway.

Glad I'm waiting for next year. The low peak brightness on these tvs and minor hdmi 2.1 issues and some lacking ports just doesn't hit all the buttons for me to purchase right now.

This is exactly why you have to wait a few years to get a TV which can maximise the assets of new consoles.

Everyone going on about how the C9, CX etc. are future proof the past few years needs a reality check.

I doubt OLED will be any brighter next year and the gamma bug will probably still be present.

Yeah, I am hoping that's not the case but I understand the reasoning behind the lower peak brightness on OLED. Gamma bug is possibly fixable , adjusting the cruves but does seem to be a large undertaking, best would need a full revision of LG TVs.

I think it speaks volumes to how awesome Nextgen is when both consoles actually exceed what most high end TV's are capable of.

Damn feel like i dodged a bullet here... hopefully they get this sorted for next year's TV releases (As everyone else here said)

I'm an LG C9 65" owner and may be upgrading to the 77" CX.

Xbox series won't fluctuate much at the desired frame rate so doubt it will be noticed at either 60fps or 120fps.

Pc players need to be making sure the settings used are enough to hit desired fps majority of the time ie 4k@60fps or 4k@120fps or drop down to 1440p@120fps like I do.

This way any gamma issues won't be noticed and to be honest variable refresh rate isn't a miracle worker that can jump between 40 fps and 120 fps without a user noticing so always best to try to get the frame rate you want using settings on any screen.

Exceed ?.. how come ? if NG console has those game at 4k 120hz with VRR + HDR turned on ? where would they test it ? CX ? X900H/Q80T those with 120 hz/vrr issue ?

The consoles provides those features just for the sake of providing it but not yet fully tested. I would not call it exceed, coz they are not proven yet.

It means consoles providing those features / or support vrr bla bla.. not yet fully tested.

No - it's that even people who bought really high end TV's can't keep up with what the consoles themselves can do.
I mean it was not that long ago I got a TV and went with a pricey 75" Q70R - I'll be gaming at 4k/60 with HDR10
the limitations are mostly on the side of the TV not the console and that is awesome and is a first AFAICT.
 
Don't have my hands on my new Xbox yet but delivery looks set for today. I'm hoping that it works at 1440p120hz on my Asus PG279Q.. I know it won't get VRR, and the HDMI port on this thing is 1.4 so I know it has to run a lower color spec to hit full res and 120hz. The bright spot for missing out on the PS5 (which last I heard won't output 1440p, and my monitor won't accept 4k) pre-orders is that theoretically I don't need to get something 4k120hz just yet and can see how reviews shake out. Also a good chance I'll need an HDMI->Optical extractor in the long term, and I'm not sure any of the readily available options will do the trick and preserve the whole HDMI 2.1 spec out the other side. So hopefully that's another thing I can let the community in general science out before I commit.

No issues with my lg oled....runs fine and was easy to setup
It is using 4k VRR 120Hz the issues.
Do you have a device like the new consoles that output in that resolution with 120fps and VRR?

Because all 2019 and 2020 OLED LG models have the same hardware issue.

Is that really the case? If so, do you have a source? I'm not saying I don't believe you; I've just seen other people say that there'll be a fix.
Most tech guys thinks it is not possible to fix via firmware but nobody is LG that is doing the code of the firmware... so it could be possible to fix.

Yeah, there's some hope, I guess. I've seen threads where people say LG have completely denied it and some where they say they're sure it's hardware and that it can't be fixed. I have a 65" CX arriving later this week so I'll be keeping an eye on this stuff. I have a fairly good return window if I change my mind. To be honest, I'm not desperate for a new TV right now so if I knew it'd be fixed in a few months with a new model I'd potentially wait. Sadly, there's probably no chance anyone outside of LG knows if that's the case. Thanks for the reply anyway.

What we need is a Digital Foundry video on this topic. I know John loves his CX and has a Series X so it'd be nice to get his input but I don't believe it's been mentioned in any of their videos.

Well, for my Q95T (EU) 1403.1 has been released just yesterday. So I'd figure there shouldn't be any more new ones at this time.

Hadn't heard of him, but I did check him out. He seems angry about OLEDs. When deciding on the CX, I used a multitude of sites, RTINGS.com being the main one. Wirecutter, CNET, and some youtube channels like FOMO and HDTVtest. I think there are TVs that will do better color than the CX, but not better blacks. I have had my CX for 2 weeks and have not adjusted the color setting yet, but I am extremely satisfied with it. Everything looks amazing so far. I will calibrate it when I get the time, but for now it looks good without it.

One thing as consumers we get into is the tearing down of what we did not get so we can feel good about what we did get. If you want a Samsung go get it. I want a TV with HDMI2.1, I think that matters, and the best gaming TV out there right now acording to the most sites is the CX.

Yep, I have the same firmware.

Anyway, I will download gears and give the 120hz multiplayer a spin tonight. But in the dash, 4K 120hz with VRR works no problem. I quickly loaded up a game and checked a 60hz native game, and everything was tip-top. Well pleased so far. I will report back on gears at 120hz
 
This would be an appropriate thread for this question I think, I've got an LG 65CX and a RTX3080 connected together with a HDMI 2.1 cable. It seems to work fine most of the time, a few handshaking issues now and then but on the whole it's ok. But on certain dark screens I notice the screen is flickering, wasn't there something to do with lowering the refresh rate slightly to 119hz or was I imagining that?
