My monitor is connected to the CPU with a hdmi cable, when I change the input source from DVI to HDMI using the menu, the screen blacks out for a second and revert back to DVI (either that or it stays in DVI). I have tried changing to HDMI dispaly sevral times but to no avail. Any help will be appreciated!
What CPU?, CPU means Zero. (in truth it is CHIP only. !)
are you in India where they say everything is a CPU, (falsely)
?????
you are posted to computers, (and no COMPUTER stated at all)
Desktops,laptops, notebooks, netbooks, all-in-one junk., PADs
and lots more. what?
are you using HDMI adapters?
are you trying a 2nd HDMI cable (yours is bad)
the computers, (unstated) is it running windows or linux or what?
if windows, are the video card drivers correct, (if not HDMI will fail)
HDMI also runs sound on a PC.
GPU drivers, what ever computer in hand.
As other poster stated test the monitor on many HDMI sources
Computers, of vast types with HDMI ports.
Blue ray players.
Hi, maybe there's no video coming out from CPU HDMI port , and that's why monitor returns to DVI input, to test monitor HDMI input you can use another HDMI video source, as a DVD or Bluray player.

The cable box is probably outputting a resolution the monitor is not compatible with. Computer monitor and television resolutions are usually different, and not cross compatible in some cases.
For example, wide screen monitors are usually 16:10 aspect ratio, while TV is usually 16:9 aspect.
The AL2216wbd is a 1680x1050 display, while HD TV is either 720p (1280x720) or 1080i (1920x1080).
If your cable box is set to 1080i that would be too high for the monitor. You will need to set it to output at 720p, and even then you will probably get a vertically stretched picture since the monitor has a taller aspect.

I don't think your doing nothing wrong, but I may be wrong. I would just stick with the other connections. HOpe this helps!?
Please rate solution - Thanks.

Not Good..
After you've checked that the video cable is connected properly, make sure that all the pins in the video cable plugs are straight and not broken off. Then test on another PC. Make sure your CMOS battery has not gone flat, as some PC's will fail to load basic drivers if CMOS memory is lost. The battery should show no less than 2.5v, if it's marked 3 volts when tested on a multimeter. If you can't test it, just buy a new one at the supermarket or hardware, usually around $4.00.
Next thing to try is your Video Card . If it is an on board one like most are now, there isn't anything you can do but try another card in an expansion slot or fit a new motherboard. At this point, I'm sad to say, you're better taking it to a PC shop where they will have a few things at their disposal to try.

The cases these days are hard to open, they use plastic finger hooks types, they go in easy but real hard to remove without damageing them.
Use thin flat blade to crack open at the bottom edge so the scratches will not be so noticeable, and work your way around, look out for cables attached to the front bezel also.
