2310 HDMI Problem

Question

I bought an Acer computer and a junk LCD monitor that died on me in less than a week and I had to return.  I went with the HP 2310m instead.  Got it hooked up and the desktop is about a half an inch too big all around when HDMI output is set to 1920 x 1080.  If I lower resolution to 1776 x 1000 it all fits with some extra black around edges.
The VGA connection works fine on 1920 x 1080.  The HDMI worked fine on the junk monitor I returned.  I called Acer and they ran me through a couple of tests and said it must be the monitor, called HP and they ran me through a couple of tests and said it must be the computer.
It's an intel integrated G45/G43 Express chipset.  I've tried downloading most recent intel driver and no luck.  I don't have a DVI device to try.
Any ideas would be appreciated. 

Answer 1

I decided to give tech support one more try tonight since I really like the look of this monitor (except when I can't see 3/4 inches of the edges in HDMI mode).
Of the three calls, they all told me it was my graphics card, but couldn't explain why the signal from the DVD player hooked directly into the HDMI input also had the edges cut off since it did not invovle the computer at all.  (It's not the cable, I've tried two.)
The tech on the first call was useless.  On the second call I told the tech that I couldn't access the "CUSTOM SCALING" adjustment in the "IMAGE CONTROL" section of the menu which, according to the manual, should fix this sort of thing.  It's greyed out and I can't get to it.  He said that didn't sound right and asked me to hold.  After 10 minutes he came back and said they were having the same problem on a monitor in their office and they were trying to solve the problem.  Another 10 minutes went by and he said they couldn't figure it out and I should call back in two hours.
I called back, got a different guy who told me there was no way to hook me back up with the second guy.  He did end up offering to have me sind it in for repair.  I told him I think it's more than a problem with just this monitor because the one in the second guy's office was doing it, and the one on display at Office Max did it when I went back to test it a few days ago. 
I guess I'll exchange it and see if the new one does it, too.  The picture is so good that I don't want to give up if it's a tech problem that can be solved.
