Can I downscale on a mirrored second monitor?

[CalDaMan]

Hi, is it possible to have a 1440p game running on one monitor and mirror it to a second 1080p monitor and have it downscaled to fit the screen? I'm on windows 10.

Thanks

Edit: Basically I want to play a game and mirror it on two different resolution monitors. I know I could just play the game in 1080p and mirror that, but I'd like to play at full res on the first monitor if possible.

I think you can game off the larger resolution monitor but mirroring on the smaller resolution might be awkward or not happening. You could try Display Fusion or apps of the same nature as listed here.

Might want to include the make and model of your monitors and your GPU.

It doesn't work like that.
Original and mirrored image has same resolution. 1080p monitor can't show 1440p signal.
Only way to accomplish this is to run 1080p signal on both monitors.

Well, is there a way to get the image on another monitor without mirroring?

Edit: My GPU is a GTX 1080, the 1440p monitor is an Acer Predadator (running 1440p 16:9, not 3440x1440p 21:9), the other monitor is an old LG TV.

Actually Windows 10 does allow you to run a duplicated desktop at the resolution of the highest display now. The lower resolution screen will display a downscaled version of the image. For example I can run a 1440p monitor and 1080p monitor in duplicate mode, and set the desktop to 1440p.

So the answer to the main question:

Yes, you can do that.

Hmm, I stand corrected.
Just tried it. Yes, it works.

Downscaled image on 1080p screen looks rather blurred though.
Which windows update added this?

Doesn't work very well. 4k screen gets locked to 30Hz. Also not possible to set 120Hz on 1080p screen anymore.
