Poll: ** LG 27GP950 AVAILABLE TO PRE-ORDER NOW - LIMITED AVAILABILITY **

[shankly1985]

Hello, I am also an owner of this monitor and I just wanted to mention that turning DSC off is not a general solution - I have a 1080 Ti, so I am limited to 4k120Hz no-DSC by design and the issue is still present.
In my case FreeSync turned on seems to be the only constant when the black screen occurs.

You not the first person to tell me this. So far I am yet to have a black screen in my time playing however I also have not played much dark souls either.

In my case it might just be very less often like 144hz I could go days without a black screen but enabling 160hz a black screen would happen daily.

Something else I have done is turn off local dimming do you have this enabled?

So I have just bought this from the rainforest, Cable Matters DisplayPort Repeater and a 1m cable matching what I have now that will come tomorrow.

So I am thinking these black screens are due to the limitation of the cable 3m pushing max refresh rate and resolutions. I also think the reason for the cable in the box saying 5k on it is a given that is also not good enough for the total max of this display and the reason for the ultra HDMI included in the box is LG recommend using that.

Now this is all speculation on my part but has anyone in here ran this monitor without a black screen on the HDMI port? also, have you guys tried just 120hz? Because for few days now its not happened at 120hz 4k.

I will report back if these thing works out but given the nature of my black screens I have set a two week if I can last that long I will say its fixed.

If not well rainforest is excellent for returns and I will just return it and added it to the long list of what I have tried and pass this onto LG when I hit them with a replacement unit, this is the last thing I am trying with this monitor and tbh I think I have gone long enough now and most users would have been already demanding a replacement by now.

Yep, I think you are right.

Firstly I'm just using the monitor on basic settings without HDR. Just set to fast with DAS on which was default for my monitor.

So I bought an 8k cable from the rainforest which should be fine. I was getting black screen flickering literally every second, I had to put it on 60hz from 144hz and then it seemed stable... so not sure if that is the cable or monitor.

But, I tried the 5k cable supplied with the monitor... everything seemed fine until I started playing a game (was playing diablo 2 resurrected) and I would get the blackscreen like once every few hours. While that isn't terrible, I can't have my monitor basically turning off and on again.

So now I am just using a high quality hdmi cable and running it at 120hz. No black screen including while gaming for some hours so far, but need to test a little longer.

Definitely something up here... This in theory should be totally fine and it seems that many people have this issue, this is basically a defective model at this point and LG need to do something as they are selling a product that doesn't work properly. If anyone knows of a display port cable that has never given them issues at 144hz even after lots of gaming, a link would be appreciated.

So my GP950 that I received on 09/08/21 has developed a fault. It has only been powered on for 95 hours. I get horizontal lines and ghosting on both HDMI and DP. I tried plugging in both my laptop and PS5 and can't even get a picture via HDMI. After about 20 seconds the screen then goes blank and I have to power it on again. I called Currys and was told to call LG as I have had it more than 30 days. Spoke to the LG customer service people who say an engineer is going to call me and then arrange to come to my house to fix it, which seems odd and unlikely he/she will be able to do anything. I'm really annoyed and assume i'll be without a working monitor/replacement for quite a while.

I was loving the monitor up to this point. Cyberpunk in 4K HDR looked amazing.

LG monitor warranties are turning out to be quite awful then...

Good luck with LG, they're known to hate fixing/returning this specific monitor.

Well they would have a hard job denying that there is something wrong with it.

Bold of you to assume they'll respond at all

Well a local repair company working on behalf of LG rang me today to say they are coming to my house next Wednesday to look at it. I'll post an update after this.

Seems like a lot of hassle really after spending £800, so glad I returned both of mine 3 months ago for the black screen effect and got the GP850 instead for £399

This looks very similar to the issue I had, although I was only getting it on one half of the panel.

QC on these monitors is terrible it would seem. Coupled with the black screening issue and having had a refund, I'm going to pass on the GP950 and wait for the next gen of 4k, 144hz - seems this one is just a minefield for reliability.

I'd take a refund and have a Gigabyte M28U instead, assuming I could find one in stock of course.

Not the best solution or anything but as a result of a process of elimination and such, this is so far what seems to be stable for me for no black screens.

-I am using a high quality HDMI 2.1 cable and using the monitor at 120Hz.
-I am not using HDR, monitor is set to "Fast" and "DAS" is on. Standard default settings on the monitor for me.
-I turned on GSync in the nvidia control panel, and am using Freesync Extended setting on the monitor.
-I swapped the plug used so the monitor is using a newly bought decent power extension cable with essentially only the monitor on it (just one of my audio monitors is plugged in there too which uses very little power, my pc, other monitors etc are running off of a different power socket and extension).

So far, not one black screen with many hours of gaming, perhaps 20 hours or so, at max graphics on a 3080ti played. I may try to move over to display port at some point and see if the problem still exists there, although all I'm really gaining is 24Hz which is about 1ms improvement, so not a lot gained really... most newer games don't get to 120fps at 4k max settings either too.

Apart from it maybe being a display port issue with the monitor which is maybe the issue... I wonder if it was just because I had GSync in nvidia control center off, or, it could have been because I was running off an old extension cable with lots running off of it. I read that old power extensions and socket with poor quality old capacitors could actually affect the monitor, don't know if that is really true.

It has been 8 days since my last black screen after I switched to 120hz DSC off, I also set the local dimming to off so I should defo check 144hz or 160hz again with local dimming on.

There seems to be a fair few good 32" 4k 144hz options coming fairly soon, which I might hold out for. The dream would be an Asus ROG Swift PG32UQX, but I'm not quite ready to drop 3k on a monitor.

Yeah they can go suck a dick at that price, MiniLED is not costing that much apparantly!

2k would be still major amount for its flaws and weaknesses.

For example response times just aren't up to modern level.
And despite of hype that FALD still has heavy bloom/halos around compact high contrast objects on dark background.
No doubt excarberated by that insane nuclear explosion brightness.
We would simply need like 100+k backlight zones for FALD to start keep blooming/halos under control.


Unfortunately also other 32 inchers seem to be somewhat so and so.
PG32UQ's panel is also average in response times and variable overdrive feature advertised by Asus seem to be badly adjusted/bugged:
In TFTcentral review response time actually improved slightly at low hertzes, but overshoot creeps in already at 100Hz.
Hopefully Asus can fix that with firmare update and lower overdrive starting from 100Hz and slightly increase overdrive above that.
(same panel using Viewsonic XG320U should have similar response times according to Chinese review)

Innolux panel FI32U has better response times... With too agressive overdrive making overshoot rear up its ugly head if refresh rate drops even to 100Hz!
And only lower overdrive option is disabling it which makes it again slow at 144Hz.
Also colour gamut is only mid wide behind 27" LG and especially AU Optronics panel.


In this situation one can only be seriously disappointed to panel and monitor manufacturers.
They've been promising for years that high refresh rate 4K monitors are under work.
And now when they start appearing it looks like they're some old tech from rear rooms of warehouses.

Unbelievable. Only had 2 black screens since purchasing mine until today. 17 black screens in 25 minutes playing Days Gone. Now I've been playing this for a month on this monitor and as I said, only the 2 black screens previously. Same hardware, no new installations of updates so I can't see what has changed. Damn. Just got another black screen as I was typing this.

Are these black screens like for a few seconds and resume like normal?

You also black screen on the desktop without no game running?
