Hi everyone. I have a Geforce 8600GT on a Dell Vostro 200. I have been running it with dual monitors (Dell 19" and Samsung 40in HDTV). For some reason the HDTV is now saying no signal and my computer sees it (tells me that I have 2 monitors) but when I tell it to clone or extend my desktop it won't work anymore. I have all the latest drivers and when I run Linux it works but its bugging out on me for XP for some reason. Any ideas?
