New OLED monitor makes PC unresponsive sometimes

[MxPhenom 216]

This may seem like a total mystery of a question, but I just hooked up a new OLED monitor yesterday and I noticed it caused certain things to be really laggy. Like opening windows settings, or when logging in from a boot up or locked screen. PC was not like this with my IPS. Anyone have any ideas or experience with such behavior? Was going to try updated my GPU drivers and maybe chipset first.

Doesn't make any sense that a monitor would cause this.

how are you connecting the said monitor to your system? is it a new cable? maybe swap the cable and check.

Yeah that is another thought. Im using a 10ft dp cable I was using with the last monitor (it's a off brand one from Amazon lol). Will try the one that came with the monitor later today.

Definitely, try a good cable first.

100%, The included cable is 'expected' to be sufficient, but it wouldn't be the first instance it ended up being not.
In case you end up needing to try another,
Club3D makes reliable cables, and is my go-to recommendation when a display cable is in-question.


I've also had a similar issue come up from a failed PSU in a display, that shorted low-current ~60VAC to ground (and into PC chassis/GPU).
It caused weird performance issues with the system and eventually BSODs and hard locks.

Replacing the display remedied the problem w/ the PC (GPU seemed to have survived)
Replacing the PSU in the display, restored function of the display.

Thirding the cable suggestion. If the included one is too short for your needs - acquire something that suits you from Club3D or UGreen or any other reputable company, they are usually not that expensive. If that still doesn’t solve the issue I would just not waste time with arcane troubleshooting and just RMA the thing.

Oh fun. Alright I'll try cable later. It might be too short but I might be able to make it work for now

Does this issue occur if you lower the refresh rate to 240 Hz?

I'm thinking this might be a DSC bug as that has plagued Nvidia cards for awhile.

Didn't think about that. Also I guess there is a firmware update for the thing too

The cable is important, especially if you are running high bandwidth. Make sure to get a VESA certified cable, keep it to 2 meters (6.56 ft) or below if it can be helped

Roger that. Was just reading up on VESA certs and how much harder it is to meet certifications on longer cables. My hope is the one that it came with is adequate. It's 6.6ft, and perhaps my 10ft one is just buns

Usually shouldn't hurt to do that as well.

The cable that comes with the monitor is usually good. If you need 10ft, here is a certified 10ft cable (I use this one so I can vouch for it): https://www.amazon.com/dp/B07KCZDZXC?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_3&th=1

So different cable didnt change things. Still very laggy when the monitor is connected when doing certain things like Windows Settings > System > Power or trying to log in, after reboot. Disconnect the monitor and system is responsive in all of that again

I don't know the answer but I had a similar problem a while back. I connected my Windows 10 PC to my TV using a 2 metre HDMI cable, I used the TV as the only monitor. The picture was fine but if I tried to play a game or watch a movie there was intermittent lag which didn't occur when using my regular monitor. I have no idea why because the cable is known good and works flawlessly with an Xbox or PlayStation console on the same TV. Same refresh rate (60Hz) as well. But it just didn't play ball with my graphics card for some reason. But another HDMI cable in the same HDMI port on the graphics card works with my PC monitor. Go figure.

What monitor is this dude? The ASUS ROG XG27ACDNG listed in your System Specs?

I might try a driver update just as a last shot ditch effort. Otherwise, ill return it

Right

Does it happen both over DP and HDMI?

just tried with HDMI. Still kinda of laggy when clicking through things. Its odd it seems to be mostly when im doing stuff through Windows.

Many modern OLEDs are limited to DP1.4 spec over DP but support 48Gbps HDMI2.1. My LG 32" 4K Dual-Mode OLED, is one of those.
-and, it appears to be the case on theirs, as well.

Could it be a GPU power state thing? -something nV's done to help keep high-hz high-res displays from upping idle GPU power*?
What was your old display that worked fine?
Are there still power options in nvidia control panel, or whatever it's called today?

*My 7900XTX esp. and my RX 9070 XT lesser so, both see noticeable idle power consumption differences relative to set refresh rate.
I know AMD got ragged-on for idle power consumption on high-hz displays. But, I have to wonder if nVidia's 'fix' is compromising instantaneous responsiveness in Windows Explorer, etc?

I had a Asus IPS that did 240Hz

 

[LabRat 891]

I had a Asus IPS that did 240Hz

1440p also, I assume?
-so, no. It's likely not a power saving thing.
If it didn't do it @ native res+240hz on your old display, it shouldn't be doing it here (at also-tested 240hz).

Only other things I'd be willing as a customer to pursue (before exchanging/returning) would be a firmware update/contacting support and/or trying it on another PC. -maybe, even a game console.

 

[evernessince]

Question, does this monitor exhibit the same issue across multiple systems? This would allow you to isolate the issue to just the monitor or the specific system you were / are using.

I don't have access to another system to try

Sure, I just wondered if the same behavior would happen when using the other port type.

I was reinforcing that. Plus, another user mentioned a potential DSC issue.
There's reason here that HDMI might be 'better' than DP, and I was expanding on that.

no worries

Ideally to test (to see if it is DSC-related),
Try 1440p 10bit @ 240hz (or less) over HDMI 2.1. That, shouldn't need DSC at all, but 360hz does.

Yeah it does do the same thing. Under System if i go into Power mouse freezes up for a bit nothing happens, then it loads. So far the only part of windows settings i have been able to recreate the issue. Itll do it on Display too sometimes. There is one comment on rtings of someone who has the same problems. But no responses to their comment.

EDIT: Did the firmware update. No change in behavior

Might just return this thing
