Custom Resolution Utility (CRU)

[Suszter]

Hello good sir,
First of all i am thankful for your work, i was surprised to see you still actively supporting the project and users. Secondly i have a question about changing the image size in the screen size block. My TV is overscanning in hdmi mode but not in dvi mode, i suspect it is because of the wrong data in this block but i seem to not be able to change it. I edit the bin file in EEditGold, export it, import in cru editor and upload it, but the next time i export the edid it is changed back to the wrong size. Is this like a security feature, or does it simply not let me override this part of the edid? Also do you perhaps know the reason why the overscanning only happens when hdmi support is added and not in dvi mode?
Greetings!
