After a good amount of searching and reading through posts on these forums of people replying in an irritated way that the 4000 series is outdated and isn't supported and wont work with Windows 10, I found a fix that was posted/works. I'm reposting it here so that others may hopefully find it easier. Also as a note to those who just said buy a new card or go back to windows 7, don't give up so easily, if you don't know the answer you don't have to post something. If you have an idea that may help, post that, but there's no need to get frustrated because people ask the same question over, just ignore it or help them find the answer they're looking for. Thanks!
I believe this will remove the overscan/underscan for any AMD card but I have only tested it on a Radeon HD 4800.
TRY AT YOUR OWN RISK, editing the registry can cause serious problems.
On to the fix!
- In windows 10 click Cortana, search for "regedit", and run it.
- Click File, Export and save as "backup" to wherever you want, just in case something goes wrong you can revert it back.
- On the left navigate to the path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\
- In this folder there will be multiple folders with long names, look for the one with a folder inside named "0000", there will be a ton of other settings, on the right, once you find the right one.
As an example the folder name my "0000" was located in is "{55038BE3-BCB9-4757-9ACF-05AC30F7CBF9}"
- Next right click the "0000" folder and click "Find", search for the resolution you are using, in my case it was 1920x1080.
- It will highlight it on the right, for me it was "DALR6 DFPI 21920x1080x0x59", the last number is the refresh rate for the screen, look for the refresh rate you use if the first one it highlights is not the one.
- Right click the highlighted name and click Modify
- Here we want to change all the numbers on the right to 00's, put your cursor before the number you want to change, press the "Del" key, then press "0".
- Click OK, minimize the registry and right click the desktop, Display Settings, Advanced Display Settings, and change the resolution to anything else, then back to the resolution you edited in regedit. Your underscan should be gone! (Edit: If changing resolution doesn't work, try rebooting.)
