help Display resolution issue

[aliasdred]

 

Monitor: BenQ 1080p-144hz monitor (XL2411p) connected via Display Port

GPU: GTX 1050Ti

When I started my pc everything worked fine, but then after starting and closing a game or even alt-tabbing a game would change my resolution to 1024-768@60hz and launching the game again wouldn't solve my problem........resolution in-game would use the one set by game with ref rate also being the one set by game or set in game launch options..

When I went to change resolution in Windows(right click desktop>Display Settings) 1stly it wont change to 1920-1080, even when I select it - screen goes black comes back as 1024-768 with black bars even tho 1080 is selected.

2ndly even if it somehow accepted my 1500 consecutive requests to take 1080p as desktop resolution, it would default back to black bars 768p@60hz as soon as I touch the ref rate to change back to 144hz under "Display Adapter Properties for Display 1". Desktop resolution changes back to 1024-768 even when I try to minimize the display settings window.

Like every self-taught IT tech/Comp Sc Graduate, my 1st instinct was to turn my PC off and then on/restart.

While coming to desktop after a restart, Settings were still at 1024x768 and everything I Didn't Want it to stay at. But, my request to change to 1920x1080 and then 144hz was granted on my 1st try.

And I would continue on launching CSGO but as soon as I close the game/alt-tab resolution would change to 1024-768@60hz, and I'd be at square one.

Tried the restart and change again but this time started PUBG instead to see if this was a CSGO problem. Nope, alt-tab on PUBG starts the same problem

Now, I decided to go step by step and try to find the cause.

Firstly, I turn off the monitor and wait 1minute, then turn on monitor, nothing happens.

This is when I notice my Advanced Display Settings tab to report Desktop Resolution to be 1024x768 but Active Signal Resolution to be 1920x1080.

Then I think it must be Nvidia and their world-class driver support. So I decide to boot to safe mode>DDU-remove drivers>restart and then fresh install new/most recent drivers.

Fresh install helped. 1 restart later I could change settings to whatever I wanted.

So, now I decided to google more to understand what actually happened and why was my Desktop resolution different from Active Signal Resolution. The posts/results online don't help, no one had a comparable conundrum. But online search does confirm that its Windows Scaling Settings that results in Desktop Resolution and Active Signal Resolution to be different.

This whole nuisance was previously a once-a-month scenario, recently however it's upgraded itself to once-a-week kinda nuisance.

Pls Help

You need to install the monitor drivers (it says generic monitor)

[Constantin]

Go via Nvidia Control Panel to do the settings

Did, is unresponsive. Doesn't even change the resolution. Blacks out, comes back as 1024-768 no matter what I select.

Windows Display Settings work. But dont last and die exactly when I click on other window/taskbar/start then it changes back to 1024-768.

Did a Update Driver from Device manager after I bought the monitor 2 months back. Monitor name/model number comes up but yes, does also show as Generic PnP Monitor....

 

Oh np, found drivers on Benq's website..... Installed/updated with the ones they have on their website..

 

Is this what you were saying?

[Faisal A]

@aliasdred Yes, that is what I meant. Now go on to the monitor tab and try to change refresh rate

I went thru my usual routine just b4 I started the thread.... reinstalling drivers works(can change resolution and ref rate both after reinstall)... but works just until the next time the issue strikes.....

Monitor driver installed now its a waiting game.... if the issue doesn't resurface for the next week or so, then I'd consider this as solved.

DP and HDMI are very sensitive cables, try another one.

I don't have a 2nd DP cable...... but their official spec says DVI can do 1080p@144hz.....should I try that 4 a few days??

Did you found a solution ?

[aliasdred]

@Gary99Yes actually.

Stopped using vibranceGUI, stopped playing games with Digital Vibrance/Saturation cranked. Problem solved.

On the other hand. I now own 3 DP cables, 1 DVI-D and 1 6M fat high bandwidth HDMI.

All because vibranceGUI is a C**T

Summary: vibranceGUI is a very simple and old product, but is an absolute C**T when it comes to refresh rate changes.
