Nvidia Image Scaling not working on primary display. But works fine on the TV.

[Obsessive Power]

Got a weird problem and I'm at loss of how to fix it. Today I noticed that NVIDIA image scaling isn't working on my primary display (A Gigabytes M32U) connected via Display Port, but works perfectly fine on my second display (which I play most of my games on) a LG C2 OLED connected via HDMI

When I enable the NIS overlay that tells you if the scaling is working, it's not showing on the M32U (even if I turn off the TV). But it's showing fine on the TV and games running at lower resolutions look soft on the monitor, but sharp on the TV.

I've only just recently used DDU to clear the display drivers, so I can't see how that will fix it. Seriously thinking about installing Windows 11 again from scratch next week as it's currently an upgrade install over Windows 10. NIS was working in Windows 10.

Any ideas?

Your mean NVIDIA DSR?

Win11 is sorely bugged after the recent major update. It basically breaks nvidia stuff right now.

Not DSR. Image scaling (NIS) as in this:

Working on my TV, but not on my monitor. Have tested without the TV connected (So Windows only sees the monitor) still not working.

What's the screen native res on the Monitor?

What do you have the NVCP setting for that set to?

A TV can do that on its own. For the Monitor you must configure the NVCP for that.

[Obsessive Power]

The monitor is 4K, same as the the TV. I have tried to configure NVCP for the monitor, it says on in control panel, but it's not on.

Unplugged the TV from the PC and restarted. Tried again to turn it on, but despite saying it's on, it clearly isn't. It worked on my old 1440P LG monitor when I had Win 10, it's not working on the Gigabyte display with Windows 11.

OK did you apply the latest Feature Update from Windows Updates for Win11?

[Obsessive Power]

Running 21h2 build 22000.978. However, I'm sure I've had this issue for the past two months. Not a new issue.

Let's start off by having just the DP Monitor plugged in. Open Nvidia Control Panel, restore default settings and apply

[Obsessive Power]

I will have try this tomorrow now. Will get back to you.

Disconnected the HDMI. Pressed the restore button on NVIDIA settings, rebooted, tried it again still not enabling on the primary display. Do I need to run DDU again?

[Bad 💀 Motha]

Then try this.
Re-run the DDU app.
Go to Options, enable the options for.
> Wipe out all of my Displays
> Enable Safe Mode option

Then close the options and the ddu app and relaunch it. Select Safe Mode + Restart options.

Once in safe mode, DDU should auto-launch. Then select each GPU brand, one at a time and on each, click Clean but do not restart/shutdown.

Tick the box for "Disable Windows auto driver installer"
^ This just makes it so the OS doesn't auto download/install drivers via Windows Updates without asking, which is how Windows handles things by default.

Then once all 3 gpu brands are cleaned out, restart Windows normally.

Then be sure to go download the very latest driver for your Motherboard Chipset and GPU(s). Install those one at a time. If asked to restart at the end of one of them, do that, then continue on until all are installed. NVIDIA just put out a driver approx 24 hours ago to address issues for Win11, so please go get that.

My guess here is you are using the wrong in-game display mode. NVIDIA says that NIS only works in full-screen mode. In other words, NOT in borderless fullscreen window which is a popular setting for some games and also for dual screen systems.
I must confess I haven't tested that, ever since I started using NIS I stopped using dual screen.

[Obsessive Power]

I believe I've got it working now, although it doesn't work on this monitor like it did on the previous display.

On the older LG 1440 monitor I could set it to 4K and choose the scaled resolution in-game. But for some bizarre reason, I have to set the scaled Res in Windows first. But on the TV this is not the case, it just works no matter what.

All my games are in full screen and don't have Windows set in dual display mode when gaming. It's either one or the other.

Strange. I use it all the time with a Alienware monitor and I never have to select anything in windows. It just offers the lower resolutions in all games and I select whatever is appropriate and it just works! Funny thing is that I wouldn't have thought it was anything to do with the monitor but, well, obviously it is.

The lower resolutions aren't the problem, it's the higher DSR ones that are.
If my Desktop is set to 1920x1080 and I enable 4.00X DSR (which is 2160p / 4K when the native is 1080p) and I do not set the Windows Desktop to 2160p, it wont work in games usually. While the game might offer the visible option of 2160p for example, but when applied is not actually changing the scaling as my Desktop is still set to 1080p and thus the game is still actually displaying at 1080p.

I don't think he is using DSR, he's using NVIDIA Image Scaling (NIS). Well, that's what I use and am talking about. It pops in three lower resolutions in to your in-game resolution selections and if you use one then it up-scales the image from that resolution to the native resolution of your monitor or TV.
