1024x768 gone (1024x600 availble) on HDMI, yesterday it worked?

When I try to play a game called F-22 Total Air War 2.0 I get an error which says that the resolution 1024.768 is unsupported by the harware.. so I look into my desktop options and it looks like there is an option for 800x600, 1024x600, 1152x648 and higher wide screen resolutions but the 1024x768 is gone? I did play the game yezterday, I disconnected the HDMI, got upstairs, played a few more games, came back downstairs, plugged in the HDMI, launched the game and bam I got the error! I have a ATI Radeon Mobility HD5470 and the newest ATI Catalyst Center downloaded 3 days ago. How can I 'enable' the 1024x768 resolution again? Without it I can't play the game on my Big TV and I will be stuck with my little laptop screen.

try shutting down turning off tv
then in this sequence
make sure HDMI is pluged in
turn TV on
turn PC on

that should fix it.

Have you tried updating your graphic cards drivers to the latest version? Also what game is it?

Yes I Did, the game is F22-TAW 2.0. On other games the 1024x768 resolution won't work either anymore (Need for Speed Underground 2 keeps returning back to 800x600)

Any cuts/frays in the HDMI cord?

other HDMI cables behave the same way.

Have you tried an older graphics card driver?
