When I connect my 23" monitor (1920x1080) to my pc through HDMI, I encourage some problems.

It's not full screen

That's it. There are ~1cm black borders on right and left side and ~0,5cm black borders on the top and the bottom of the monitor. That's pretty frustrating. I tried adjusting overscan, but I can't mannualy type the % of overscan that I need. I can only select between ex. 8 and 10% in AMD Vision Engine Control center, but what I need is 9%. Next, even if i select 10% and the image fits all the corners, but after log off all the settings are lost and I have to do it again and again.

Text, images, everything looks blurry

That surprised me a lot. Should'nt HDMI quality be better than VGA's one? When connected through HDMI, the text isn't readable. It's like a very low refresh rate, although i'm running at 60Hz. Also the text has something like little shadows, very very annoying.

Are there any tips to get the same quality as with VGA, with HDMI ? (running on integrated ATI Radeon HD4200, which, appearently, is the best card I have ever seen in terms of integrated ones)
