You have the TV connected to the cable box with an HDMI cable, I'll bet. The problem is with the cable box. If you unplug the cable box and plug it back it it will reboot and proabably work. You should connect the cable box to the TV using component cables and you won't have this problem again.

SOURCE: Unsupported video signal
It is possible that Jewelquest changes the screen resolution to one that is not supported by the TV. I am not familiar with Jewelquest, but the typical reason for the unsupported message is a resolution outside of the supported range. The supported resolutions should be listed in the owner's manual.

Check your resolution output from laptop it maybe set to high for the TV to handle, also go to the Display Properties and ensure that the second monitor out is enable. Good luck!!
