Hi, i've been following the instructions in this thread since it started and they have always worked, however I can't seem to get it working with the 14.1 betas. I create the custom resolution 1920*1081 to force creation of the registry entry, I export that entry and amend the values and then add this file back into the registry but when I reboot there aren't any new resolutions. I'll show you the registry file after it's been edited, hopefully someone can spot what's wrong as I don't pretend to understand what any of the values actually mean.

i have the same problem!!! i just installed 14.2 beta 1.3 e downsampling is gone. And the same procedure with registry hack don't do nothing, i can't see any new resolution! I have a smart tv ue55f7000 samsung e i can downsample without any problem to 1920x1080 to 2560x1440. I don't know what to do! I hate you so much AMD!!! :bang::bang::bang:

What for Tools do I need to Downsample ?
I have uploaded all the tools you need in this Download link.
http://www24.zippyshare.com/v/69050434/file.html

What are the Requirements to Downsample?
-Of course an AMD GPU.
-DVI connection is preferred, on my Rig HDMI and Displayport works also.

First Steps:
Installing a Modified Monitor Driver is Required (which you will find in My Download Pack)
In order to install the Modified Monitor Driver, deactivation of the Windows Driver Signature enforcement is required. If you use Windows 8 or 8.1 deactivating the automatic driver installation is also required.

How to add a Custom Resolution:
1. First of all execute the “list.bat” and a little Command line Window will appear and will show some values which are really important. The Most important values are “AdapterIndex” and “DisplayIndex”, please write them down.
2. Now Open the resolution.txt which looks like this:

Code:

[B]AdapterIndex ? DisplayIndex ?[/B] TimingStandard 1 PossibleStandard 14 [B]RefreshRate ? Width ? Height ?[/B] TimingFlags 0 HTotal 0 HDisplay 0 HSyncStart 0 HSyncWidth 0 VTotal 0 VDisplay 0 VSyncStart 0 VSyncWidth 0 PixelClock 0 HOverscanRight 0 HOverscanLeft 0 VOverscanBottom 0 VOverscanTop 0

3. The Bold values and question marks are going to get replaced.
-the written down AdapterIndex/DisplayIndex from the “list.bat”
- Refreshrate is the Native of you display Mostly 60 Hz, so put 60 Hz there
- for Width use “1920”
- for Height use “1081”
- now save the Document.

4. Execute the “resolution.bat”, the screen will go black or blank and will restore again.
Check in Control panel/Display if the resolution is available.
If for some reason an error appears change the refresh rate in the “resolution.txt” like to 57 Hz. Don’t forget later to modify the refresh rate again in the Registry key.

Code:

57 Hz = 39 60 Hz = 3C 65 Hz = 41 70 Hz = 46 75 Hz = 4B 80 Hz = 50 85 Hz = 55 90 Hz = 5A 95 Hz = 5F 100 Hz = 64 105 Hz = 69 110 Hz = 6E 115 Hz = 73 120 Hz = 78 125 Hz = 7D 130 Hz = 82 135 Hz = 87 140 Hz = 8C 144 Hz = 90

5. Start regedit and go to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet" press CTRL-F and search for "ModeTimingOverrides”. The key that should be found will look like "ModeTimingOverrides_DVI_ConnXXXX" where XXXX is a random number that is different for everyone. Export that key and save it because we will need it to modify it.

6. Open the Saved Registry File and start Modify it according to the values and picture bellow. Save it and Doubleclick/Confirm to install it. Restart the Computer and see if the Resolution is available.

Code:

Resolution Hex Numbers 1920x1080 @ 2560x1440 Width = 00 0A Height = A0 05 HTotal = 20 08 HSyncStart = 30 HSyncWidth = 20 VTotal = 57 04 VDisplay = 38 04 VSyncWidth = 05 PixelClock = E0 22 02 ------------- 1920x1080 @ 2720x1530 Width = A0 0A Height = FA 05 HTotal = 20 08 HSyncStart = 30 HSyncWidth = 20 VTotal = 57 04 VDisplay = 38 04 VSyncWidth = 05 PixelClock = E0 22 02

I hope this will help you abit guys. I translated and modified this Guide from a German Forum.

Thanks it works for me! I don't understand what was wrong with my precedent reg key saved. Maybe something is changed!

No matter what I do, I cant get it to work in any method on Windows 8. I really, really miss downsampling. I only care for it on older games. Playing NFS Shift in 3200x1800 res was just awesome with my 560ti 448. Ive tried using HMDI, DVI, and even just 1440p on Analog.

First of all, thanks for taking the time to translate the German guide, I tried following it before and just got lost.

I have the custom resolution in, 2560x1440 downsample to 1080p, but when I apply it of course its out of range on my screen. On Nvidia I enabled GPU scaling to solve this, but when I enable it in CCC the resolution is no longer available.
What do I do? Also how do I install the custom monitor driver, right click and Install doesn't work, neither does using "update driver" in the device manager.
Is it automatically installed by the .bat files when you run them?
I've disabled driver signature enforcement already.
Sorry if I'm making some dumb noob mistakes here, downsampling is much easier with Nvidia :/
I'm running 14.2 beta 1.3 drivers.

EDIT

WELL.... I figure that it's my HTotal that is the issue. If I try 20 08, then its simply a black screen. If I use 98 08, then it gives me the shifted image! :bang:

Edit: FIXED IT!!!! :banana:

The issue was simply HSyncStart and HSyncWidth. Thank you!!!

THANKS!! This worked straight away, you're a lifesaver man! :banana: Been sitting watching my housemate running Far Cry 3 downsampled all day on my old 660ti, getting increasingly tempted to get a Nvidia card :bang:

If you've done it previously on the older 14.1 beta, then the downsampling settings should stick on 14.2

This was the case for me anyway.

I just hope someone comes up with a way of doing it easy, because it was a hell of trial and error for me before the 14.1, and I haven't being able to make it work since 14.1... maybe in a future version of RadeonPro or something like that?

i was able to get downsampling to work on a r9 290 using the registry entry. thanks for the help here. using 2560x2048 and it looks much better. 13.11 b6 driver. Pretty easy to do.

1. install monitor driver. reboot

2. use list.bat, resolution.bat, & resolution.txt to create the new resolution +1 on horizontal.

3. export modetiming reg file, edit width, height, & vstart. add reg, reboot.

I know some people have problems over 2700x1500 on 7000 cards, but with my 7970 i was able to use crysis 1 dx10 tommit SSAA tool to internal render 8000x3000 pixels. Took some tiled screenshots via crysis console at 120,000 x 90,000 resolution. 300mb image files.

Rendered game at 14,000x6000 (5 fps)... hehe just to text maximum resolutions and frame buffer. Maximum playable was 8000x3000 resolution which was selectable in the game menu.

so far on the 290 i have this 1280x1024 monitor @ 2560x2048 but it may go higher, i might test later. FPS is down to 20-30 at this resolution, so no need.

I never tried 14.1.

Had 13.11 Beta before and thought I should may be try 14.2 Beta because the change logs mentioned that it solves certain application/game crashes.

Lost the resolution updates (which was added via regkey back then) and couldn't see/add more resolution the same way in 14.2 Beta.

So I just downgraded to 13.12 WHQL currently.

Note: I didn't try the other method thou, just a bit wary about loosing my monitor color profile I took time to set.

13.12>14.2= no more downsampling possibility :cry:
Same issue I saw on another forum:

"just installed 14.2 beta 1.3 and downsampling is missing! And with the registry change i get many ModeTimingOverrides in various locations in the registry and the old one in the old location, changing that don't do nothing! Any clues ? :/ "

Did anyone succeed??

Hi everyone, I just recently managed to achieve 4K@60hz on an old 6870 running Catalyst 13.12 and an ASUS VW246H through hdmi, Win 7 x64.

I have 2 questions so far:

1) there seems to be a problem with resolutions above 1440p (1620p, 1800p), they just don't look as crisp as 1440p, the aliasing is evident in game, not so on screenshots.
I suspect this has to do with the scaling but since it must be disabled on CCC to allow for the other resolutions to show up in Windows I'm at a loss as to how to fix it; that 1440p looks as intended is even more headscratching.

2) 4K on the other hand trims everything nicely, but since I have to previously switch to a lower resolution (1440p) for it to fit in the screen, I've noticed these vertical lines (currents) running down the monitor. These do not show up when I select 4K directly, but obviously there's little that can be done with 1/4 of your screen at any one time.

thanks in advance for any help, fellas!

EDIT: managed to fix #2, had to lower the pixel clock rate from an automatically assigned 140000 down to 129600 (2160x60)
I'll try to manually add pixel clocks for the rest of the resolutions and see if that settles #1.

If you have making your own reg.file for the old 13.xx drivers, you must change it a little bit.
With the old drivers in ModeTimingOverrides every data block for a resolution ends with: 01,00,00,00,c0,00,00,00.
You must change it with 01,00,00,00,00,00,00,00,80,00,00,00.
For example, this was my reg.file for the resolutions 2560x1440, 2720x1530 and 2880x1620 with the 13.xx drivers:

After changing, downsampling works without a problem for me with the new driver AMD Catalyst 14.2 BETA 1.3.
I´ve tested it with 3 monitors:
1. LG W2442
2. BenQ GL2450HM
3. Asus VS248H
No problems with all 3 monitors.
Sorry for my bad, bad english.

Strange, I just did a clean install of 14.2 beta 1.3 from the 13.12 WHQLs using DDU. Followed the Anypaper's post here:
http://forums.guru3d.com/showpost.php?p=4771086&postcount=653

Didn't even install the modified monitor driver as suggested and it worked perfectly, just like the 13.12s previously. Now let's just hope it works out again next week when the new betas roll out.
