So I just purchased this new monitor (the Samsung T220HD) and am generally happy with it but am having one very annoying problem. When I'm displaying a picture from an HDMI source, it restricts some of the picture settings I can adjust; namely the sharpness and color saturation levels. Curiously, they can still be altered by changing the preset picture settings but it prevents me from adjusting them manually (on the menu, the adjustment bars just appear greyed out). I am able to do so when using component video or VGA but not with HDMI. Is there some logical reason for this? It can't imagine one and I'd really like to set the color saturation higher than 50% when using my Xbox. Has anyone else experienced something similar?
I'm still yet to get to hdmi (got a gtx 295 coming next week though) But I think the problem is that you are dealing with a digital signal (HDMI) instead of an analogue one (VGA). This is just my conjecture however but it seems to me that in a digital signal as the data sent can only be 0's and 1's there shouldn't be any need for adjustment as the source media should be reproduced perfectly. A classic example of this is how my screens here let you do an 'auto config' while connected via VGA but there is no option while connected via DVI as the picture is always perfectly centred and produced. Correct me if I'm wrong anyone however.
