Another dumb-*** idea that provides no user benefit. When Acer developed its LCD monitors with DVI and HDCP support it decided to leave quality control in the drawing room. The annoying message "Input Not Supported" when it is obviously supported eliminates the potential for using their monitors with cable TV boxes and many game boxes. http://www.4rails.com

That is because the resolution is incorrect for the monitor.

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.

My assumtion is that the monitor is not displaying in 1920x1080 but has defaulted to a resolution that it can handle so as to display something. Step down the resolutions on the monitor until the gray box disappears. If you're satisfied with the picture your watching then hopefully you will be happy when you find the resolution the monitor is actually displaying.
Good luck!

You get the message because the game try to run at the PC video resolution that you monitor cannot display/support. You need to run your game at native resolution of the monitor.

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.
