Setting custom resolutions (ATI) via Registry

post #1 of 3
Thread Starter 
People have been having issues for some years now concerning setting custom resolutions for their AMD Cards. I used to have such issues since for some reason, newer version of CCC do not give me the 1600x900 @60Hz resolution ( on both my 1080p displays). So, here is a short tutorial on how to set custom resolutions via the Registry ( Note: This is done in windows 7)

(I have not tried this with an Nvidia card so this is primarily targeted towards AMD card users. If it works with Nvidia cards, let me know so I update the thread accordingly)

1) Open regedit:

2) Go to Edit->Find. And Do a search for "DALNonStandard":

3)Hit Enter to begin searching the registry. When you get the first hit, it should look something like this:

reg1.png

4) Double-click on the highlighted "DALNonStandardModesBCD1" to open the "Edit Binary Value" Box shown below:

5)There should be a line with a header ( in this case, 0020 ) without corresponding values like the others. On that line, enter your desired resolution.
Important: The resolutions listed above have a particular format. Be sure to follow those when entering your desired resolution. Also, please note that the resolutions already there do NOT represent all the resolutions your monitor is cable of displaying. Check with windows/CCC and only add the ones NOT listed in the windows graphics settings.

The arrow shows the line I added. The forma is as follows:
*) The for 4 pairs of numbers are for the horizontal resolution x vertical resolution. So 1600x900 will be represented as 16 00 09 00 and NOT 16 00 90 00 (This is 1600x9000 ... I'm pretty sure you don't want that res ... )
*) The next 3 pairs of numbers should be 00 00 00
*) The final pair of numbers represents your desired refresh rate at that resolution. I have mine at 60 (for 60Hz). After that entry, the cursor should automatically move to the next line with a new 4-digit header (0028 in my case). Add as many resolutions as you desire. Push okay to accept the change when done.

6) Hit "F3" to continue the search until the next hit. it should have the same value name: "DALNonStandardBCD1". Repeat resolutions you added above (preserve order) until you are done searching the registry and changing everything.

7) Reboot your computer and go to "Screen Resolutions" (Win 7) in windows and you should see your custom resolutions shown now. Like this:

IMPORTANT:
I assume everyone using this guide will know better than setting resolutions beyond your monitor's maximum resolution. You should also backup your registry before making any changes to avoid damage.

Hope this helps those with questions. Have fun playing with resolutions!

Thanks a lot mate! I think I know what you're referring to; problem is, I have tried different laptops with multiple installs of windows ( and drivers) and I never find the option there. I think it is mostly with laptops that I find missing resolutions ... and since its plagued myself and other users for years, I decided to throw this here to help someone out biggrin.gif

Merci!
