I setup a custom resolution for one of my computers (Intel DH67CF/Pentium G620T) connected to an older Sharp LCD TV. It is 1366 x 768. I did get it to work, but it didn't work right away... I had to restart the computer before the custom resolution took hold. Worth a try...
Thanks for replying...your solution worked for me! Although the resolution I put in didn't take effect on restart, after restart it did appear in the dropdown list of resolutions in General Settings, and I was able to switch to it with no problems. I had also gone back to the latest Intel drivers in the meantime so if anyone sees this in the future that would be the way to go. Thanks again.
