Hey all, i have exhausted my knowledge so i turn to your accumulated wisdom for help.
I have a Samsung LCD (LE26R73) and a Dell Vostro 1500 Laptop. I have had the two connected via Belkin VGA cable for a few months now, with no problems.
The desktop extended fine, laptop res @ 1440x900 and Tv res @ 1360x768.
However last week I turned on the TV and in PC Mode the picture was "jumping vertically". I tried turning it on and off etc, no luck. Later on it got a bit worse and would disappear entirely, the come back.
The next day when i tried it simply said "Mode not supported" on screen in PC mode. And Today it goes to standby after a few seconds of a totally black screen.
This to me indicates it's not "recieving" a signal from the laptop? I have tried another VGA cable with no luck.
However if i connect the TV to my flatmates Desktop with the same VGA Cable, i can get the TV to work as the main monitor perfectly. I can't try it as a extended screen as the Desktop only has the one VGA out.
So..any ideas as to what may be going wrong? The only thing i can remember doing is a few windows updates. But any updates before..2 days ago arent showing so i can't uninstall them?? And also system restore appears to have deleted any restore points beyond..24 hours or so ago.
So, i turn to thee, the forum for wisdom... Please Help!
