Scaling down 27 inch display to 24.5 inches (PG27AQDP specific question too)

Post by 99muppets » 27 Nov 2024, 03:33

This is a very specific (And probably strange question), but I'm unsure if it is possible. Lets say I have a 27 inch 1440p monitor for example. And I want to scale the image to ~24 inches, it's not too difficult to setup, i've done it on my own monitor, simple just running the scaling mode to "center" and reducing the pixelcount to fit the size I want.

However, would I then be able to use custom resolutions within games, to rescale the display within that pixel limit. If this doesn't make sense i'll give an example. 27 inch monitor, only displaying pixels in a 24 inch size in the same standard 16:9 ratio (black bars around edges and top). However, within this 24 inch 16:9 display, I would want to use, say a 4:3 resolution within a game, stretching the game's scaling while still maintaining 16:9 ratio of pixels displayed. I could not figure out how to do this on my random 1440p 27 inch samsung.

Basically just running stretched res on a 24 inch screen with a 27 inch monitor. Is this possible? Further, with the pg27AQDP, since there is actually a setting within the monitor ITSELF to just use a 24.5 inch display, without needing to fuck with any scaling bullshit (apparently), would this be possible / easier?

If anyone has a pg27AQDP specifically, I would really love to know if you are able to play stretched resolution in games whilst on the 16:9 24.5 inch mode too. With regards to the pg27AQDP, and in general, how would DSC affect this?

Doing some further reading, the 27 480hz LG monitor that is being released soon, I was very excited to see DP2.1, turns out its only UHBR13.5... so we need DSC anyway, so generally, is this possible WITHOUT dsc? and is this possible WITH dsc, are there any circumstances where this is possible.



After some fucking around in CRU (I kind of don't know what im fkn doing) I've managed to seemingly remove 2560x1440p from the monitors display settings and ran 2272x1278 (16:9 res that is approx 23.8inches diagonal). However, no matter what scaling mode I use on my AMD panel, whether it be preserve aspect ratio, full panel OR centering, the monitor set @ 2272x1278 will just fill all 27 inches, and when I try to use say 1920x1080, it will sit in a smaller block on the screen (black bars above and to the sides) EVEN ON FULL PANEL SCALING MODE, which to me, makes absolutely no sense at all. I'm trying to have the monitor treat 2272x1278 as the "DEFAULT" res, so when using the full scaling option, it will continue to treat 2272x1278 as the desktop res, and allow me to play games using stretched resolutions, just stretching to fit into the 2272x1278 pixels. Added is what my current CRU looks like, i've removed all the detailed resolutions. The second image also shows that when I select a random other resolution, the active signal mode shows 2272x1278 and the desktop mode is 1600x900, which for whatever reason regardless of the scaling mode, just only shows 1600x900 pixels (NOT SCALED to the 2272x1278 pixel size on my monitor). Any help would be awesome

2366x1331 (no scaling) = 24.5 inch
2318x1303 (no scaling) - 24 inch

I've been able to do this will no scaling so it works fine without custom resolutions then in game, however, I am trying to use CRU, in order to just TREAT my monitors default resolution to be 2272x1278 or 2288x1288 (apparently divisible by 8 is the best? don't understand the specifics, but the first res is exactly 16:9 and the second is very very close but div 8).

I'm trying to figure this out using CRU, to remove default / detailed resolutions but I can't find any info about this, so if anyone would have some advice trying to do this, dm me on discord or reply to this post would be awesome :).
