Mode Not supported stems for an resolution clash between the device connected and the tv. The most common issue when an tv is hooked up via hdmi to an device which does not support 480 i.

Are you using hdmi cord with your pc connection?

If your using an vga cable if so make sure the pc is set the optimum resolution. per the user manual (pc section)

If it worked a day ago, there could be a few issues at play here.

First of all, I always recommend checking to make sure you have the latest BIOS (strange I know, but it works!) and the latest driver for your laptop's video card.

Does toggling the FN+F8 (or monitor out) key send the signal to the television?

Are you using the supported resolutions outlined in the manual?

Keep me posted!

I have a laptop that I connect to my lna550 via the RGB connection. Until about a week ago it display beautifully at 1920x1080. Now when I select that resolution it says "Mode Not Supported". Now it will display in a lot of different resolutions but none of them look nearly as good as 1920x1080. I'll try updating my BIOS.

Any other ideas?
