Sorry if not correct thread. I'm desperate for help! Long story short, for the longest of times my laptop (HP 2000, Windows 7, Vision AMD) hooked up to my 26" Dynex LCD screen via VGA. It does not seem to work anymore. I either get "no signal" or "mode not supported". It will switch between the two messages about every 2-3 min, even without me changing any settings. I've played with all the settings, I.e res. refresh rate,and so on. I have tried every conceivable idea I have gotten. I have hooked my laptop up to other monitors with the same cable, no problems at all. I have also tried hooking up a diffrent pc to this TV and they will work. I have no idea why my laptop wont work for this screen anymore.
