Can you run a 1080P monitor at 4K in Windows desktop?

[lufihengr]

Ok, so I have one 4K monitor and one 1080P monitor, my problem is that Windows does not work well with the mismatch.

I would like to run the 1080P monitor at 4K kind of like DSR in games, but at the desktop. Then when I drag windows between the monitors, it would be the same size on both and I could drag the windows over from any point on the border, not just the top half.  Is this possible at all? I couldn't find any answer.

 

As a stop gap I use a tool called little big mouse which lets me drag the windows over from any point, but keeps crashing and does not fix scaling issues.

 

Another acceptable solution would be like I have it in MacOS with HiDPI so that both are scaled to 1080P, but the 4k monitor is still at 4K res and super sharp, if that makes sense. 

 

Apppreciate any help

Yes, VSR lets you do this easily, I've done it myself before  

I assume Nvidia's DSR would work as well but that is not something I could ever confirm for myself

You can with NVIDIA DSR or the AMD equivalent.

 

This is a problem inherit in desktop composition in general. I don't think it'll be fixed natively.

Yes with DSR and it works fine.

Oh, I will have to try it!

But why?

Because I want it to be perfect. Without spending money on another 4K monitor.

It works! Wow! Although it is a bit blurrier than before, and my cursor is 4x the size when I move it to the other monitor. Thanks!

The cursor thing has to do with it being hardware accelerated. Something about the desktop gets rendered, then downsampled, then the cursor gets rendered which since DSR already made a pass, doesn't do it again.

 

I'm not sure if there's a way to disable that universally.

It shouldn't be 4 times the size, it should be smaller not bigger, did you set the resolution on both monitors or just the 1080P monitor only?...because you should have only changed the 1080p one, it will be a bit blurrier but that is because your monitor is a 1080p and i am sure a TN panel because it looks a bit less blurry on an IPS panel.

Both are at 4K resolution now, when I change the window scaling to 200% it's not as blurry. Also DSR smoothness at 0% helps. It's a TN yes.

 

The mouse size is much less annoying than the other issues that I had though

It's because DSR compensates for cursor size so it doesn't get smaller. But then if you turn on Windows scaling it also makes the cursor larger to compensate, without realizing that the cursor was already the correct size with DSR.

When i enable mine, with scaling off because i never use scaling, my cursor stays the same but the windows, icons and folders get smaller and some text is choppy.

In the picture, both screens are 1080p and i only applied DSR to the Acer, my mouse is the same to me.but doesn't show in the screenshot.

Yeah, that's because DSR enlarges your mouse so it doesn't shrink with everything else. If you turn on Windows scaling it also enlarges your mouse to compensate for high pixel density, so if you use DSR and Windows scaling at the same time your mouse will be enlarged twice, which overcompensates for the shrinking, and your mouse will appear larger than it should.

Interesting, I know AMD's VSR does not enlarge the mouse (I'm doing it right now).

Here is a comparison in the mouse size. Both are at 150% scaling, at 100% on the 1080P (DSR 4k) monitor, the mouse shrinks, but it's still bigger than the real 4k one.

Right, remember i said i don't use scaling so this is where the difference in cursor size is happening.
