and toastyX ; on my nvidia cards i did use CRU to get that lightboost without gpu scaling to work. i wish i remembered how. i'm new to messing around with resolutions like this. like i heard falkentyne say something about double strobe and all this other terminology. any way i can get something close to what i used to have? or at least get it to actually stretch the screen? i guess faking the VT and HT or something so it sets it to 1440x1080 but the monitor thinks its something lower? maybe?


EDIT: i'll just give up on my 4:3 dreams and use 120hz lightboost 1920x1080p

Hi,
I'm not sure what the problem is here.
I just tested this just now on my AMD Card and it's working exactly as ToastyX said it would.

As long as the lightboost resolution exists and the normal resolution e.g. the normal 100hz or 120hz is not there, just the lightboost one, if you enable GPU scaling and switch to 1440x1080, it will be lightboost GPU scaled. You will know because the monitor wont "refresh" or shut off and resync....the existing 1920x1080 lightboost resolution will be instantly "resized". That's GPU scaling.

if FORCING gpu scaling in the driver doesn't work, then selecting a refresh rate you didn't manually create should automatically gpuscale it for you (see below):

I don't even NEED to enable gpu scaling. All I have to do is select the lightboost resolution and refresh rate as long as 1440x1080 exists in the EDID override.

You can do it like this.
Create a 1440x1080@60hz resolution in CRU.
Try front porch 48,3
sync width 32,5
hor: 2080
VT: 1125

Save it and restart the driver.
(if for some reason the monitor shuts off, try front porch 88, 4
sync width 44,5
Hor: 2200
VT: 1125)

Now switch to your 1920x1080 lightboost resolution @100hz or @120hz.

Then switch to 1440x1080@120hz.

It should resize the screen and the monitor will still think it's 1920x1080 and won't resync or anything. Bam: 1440x1080 lightboost.

Are you saying this doesn't work?
If you created a 1440x1080@100 or @120 resolution already, DELETE it. Try the 60hz one. That way all the other refresh rates (except 60hz) will be GPU scaled.
