Downsampling Made Simple With Custom Resolution Utility (CRU)

Downsampling The Easy Way With Custom Resolution Utility (CRU)-Running On AMD

CRU-the program you need:

http://www.monitortests.com/cru-1.1.1.zip

Before you do anything, create a System Restore point, it's a handy fallback to use in Safe Mode should your monitor go out of range.

Run CRU as administrator, allow it through smart screen if need be(W8).

1. Untick 'Include extension block'

2. Click 'Add'

3. Input Horizontal

4. Input Vertical

5. Optional if you have a 120Hz/+ panel, Input Refresh rate.

6. Press OK, and restart PC.

Check and see if it worked:

It really is that simple and the results speak for themselves:

Crysis 3 screenshot on max everything@1440p:

4K is working on my 120Hz Sammy 3D panel@30Hz, the resolution for input is - 3840/2160

I'm only posting a simple guide to get it working, full credit goes to the author of CRU:

Notes:

I had to unplug my second display as it wouldn't work with both plugged in-your mileage may vary though.

I would advise leaving your native resolution on the desktop and using in game settings to change individual game resolutions as the screen goes blurry when running out with your native res.

Superb

Do you think it will be possible to run 1440p @120hz on my BenQ XL2420T?

Try it, you'll find out.

shankly1985 · 5 Mar 2014 at 03:36

O wow it look so dam good lol but max I could get at 1440 was 75hz going to try 1200p

Ok just heads up guys i'll be staying well clear of this haaa just had a scare there needed to remove drivers ect.

Games glitched out where even after I reset the program it looked like Memory damage. Driver removal and thank god its fine.

I get signal distortion running anything higher then my native resolution.

Sucks balls... I just used super sample in the CCC anyway.... Works in most games tbh...

Does super sampling have the same affect?

Which games does it work in? Do you use over ride or enhance?

Great guide Tommy. Mixed success for me though.

I've overclocked my monitor safely to 66hz at 1440P, that's the max it well go sadly. Tried 3840x2160 @30Hz but i get a black/blank screen when i enable it in say BF4 for example. Think it might work if i lowered the refresh rate some more but don't want to run it that low.

So does this work now?

Not as well as the foreigners downsample (Which frankly let us do anything res wise, could do 4K etc)
This is no different to trying to use CRU last year?

I still won't try CRU etc.

Right, thanks. i will try both.

You can't do the other down sample, amd stopped it a while back with a driver update, hence why anything with amd down sample is big news.

Diddums · 5 Mar 2014 at 09:04

Never heard of downsampling before. This looks very interesting although the mixed results are making me a bit reluctant.

If you still have that gtx 770 in your sig you can make a custom resolution in nvidia control panel , Same as this but saves downloading another program

Diddums · 5 Mar 2014 at 09:46

Crap, I'll update my sig

Diagro · 5 Mar 2014 at 10:04

Will that program let me try and overclock my hazro display?

It did work but then I think I messed up somewhere and thought I damaged my GPU's. So I tuck it as a warning lol

Did you apply the AMD pixel clock patch?

Something I don't quite get though. If you're using downsampling to get 1440p @ 75hz on a 1080p 120hz monitor then surely you would have been better off just getting a 1440p monitor to begin with?

It was just for I test

I wouldn't give up 120hz for no resolution

Am waiting for the new Asus 1440p 120hz. But I did test this. Had BF4 running @ 1440p 75hz
So then tried to get 120hz @ 1200p and it worked showing up in game etc, but when I applied it my screen went all mad. I quit and loaded up GPU-z test and it even done it on there, Restart the same "Gutted" lol
Full driver restart was my only fix.

You cannot damage your GPU doing this, it will more likely damage your monitor. Your GPU is a 290 model right? Which can support upto 4k resolutions. But I know what you mean with the scary looking memory damaged sort of picture because I got it as well and had to boot into safe mode just to get past it.

It will just damage your monitor if anything
