How To Fix Legacy AMD GPU Underscan, Windows 10

My front desk computer inside shop has an Athlon 64 a 2 fitted with a Radeon High-definition 4550 graphics card, which today is known as a legacy GPU and although drivers are for sale to Windows 7 and 8, a good HDMI connection to the monitor can an underscan. That is to say, the desktop won’t fill the entire exhibit and is underscanned by around 15%. Whenever using an HDMI/DVI adapter cable the following underscanning doesn’t occur (or D-SUB VGA as an example) and it’s taken me a despite the fact that to figure out how to solve the puzzle. It’s also worth talking about that the underscan only occurs in Home windows 10 from some obvious inability of the OS to learn the correct model of GPU. None does Catalyst Control Heart open fully with the legacy of music drivers and shows some sort of cut-down version with minimal options. But there are some methods accessible for fixing the problem and as standard, I happened upon most effective route last of all.

Option One C Get into The Registry

Making changes in the Windows Registry isn’t really for the faint-hearted and before every changes are made it’s always preferable to make a Registry backup simply by running Regedit (as Administrator), visiting file>export, and selecting export range>all as per a diagrams below.

Then select?HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlVideo to get the long key (out of three) with three subscription keys 0000, 0001 and Video as per your diagram below.

Right-click the key 0000, strike find and input 19201080 while in the search box (or the resolution you will want) and if 1080 is the resolution of your monitor the key?DALR6 DFP1920x1080x0x60 will be pointed out in blue which you will need to then double-click and change every entry to zero.

Carry out the same workout on the 0001 key, close Regedit, alter your resolution to 1080 and you should find that the underscan has now gone. In my case, these keys wasn’t present so I moved on so that you can option two.

Option Two C Power Install The Drivers

Again, in my case I’m just using a Radeon HD 4550 and, making use of Display Driver Uninstaller, I removed all the AMD drivers in safe method, rebooted normally and located AMD Catalyst 13.9 legacy drivers which in turn I’d downloaded previously by just selecting Windows 7 x64 on the AMD web site, even though I’m running Glass windows 10. I then right-clicked on the drivers package, set compatibility for you to Windows 7 and clicked on run as administrator. I then let the package extract to C:AMD yet didn’t continue with the installation by just cancelling the next procedure.

I subsequently went to device manager, chosen the graphics card and clicked update driver, browse my computer, let me pick from any list, selected the HD 90 model, clicked have disk and then specific to the extracted AMD package. You could follow these diagrams one after the other and follow the tree, which usually in my case was?C:AMDSupport13-9-legacy_vista_win7_64_dd_cccPackagesDriversDisplayW76A_INF.

After clicking have disk I selected the .inf file in the list plus Windows installed the correct vehicle driver.

Once this was completed, I put in the Catalyst driver inside normal way but with interface with Windows 7 along with Administrator rights, hoping that Catalyst Control Center (CCC) would function normally and allow me to adjust a annoying underscan. Unfortunately, this didn’t operate and so I then moved on for you to option three.

Option Three C Obtain Catalyst Control Center (CCC) Manually

It’s arguable whether this should be done in conjunction with possibility two. Either way, CCC.exe was easy to find at: C:Program Files (x86)ATI TechnologiesATI.ACECore-Staticccc.exe once the Prompt software had been installed in addition to again, I set being compatible and Admin rights, using the program opening normally considering the functions available, including the all important underscan (Scaling Options).

I found the following to be by far the easiest method, particularly as I’ve employed the scaling feature ahead of on Windows 7 as soon as i connected a PC to a 32 TV. The difference here is that if you don’t dig down to find CCC.exe (Catalyst Control Centre) the driver deal installs a cut down type of AMD Vision Engine Control Focus with no entry for My A digital Flat Panels, requiring users to compromise the registry as per alternative one. Of course, if I might known where to find CCC.exe in the first place I would personally have saved myself major time. There are numerous pages on AMD boards and other tech sites focused on solving this underscan problem and also from what I’ve read, people end up with different results, however it is certainly a lot simpler to observe option two and three than coughing the registry, as the chances of something going wrong globally is less.
