Hi guys

Something very strange happened today. I have a monitor connected to the DVI port of my card (amd hd6770) and a HDTV connected to the HDMI port. The HDTV is not always on, half the time I'm just working on the monitor.

Today I left the computer in game for a long period of time (about 3-4 hours) and when I came back the monitor wasn't getting any image. The computer worked normally, but no image showed on screen, even after reboot. I connected my laptop to the monitor and it worked fine, and I connected the HDTV to the DVI port and it worked fine too.

So I booted with the HDTV in the DVI port, and then disconnected the cable and connected it to the monitor and the monitor started working, but now the HDTV doesn't get any image.

If I go to windows settings and extend, it works: I can move the mouse to the "other" screen, but no image shows. If it matters, before this happened the monitor was treated as the 2nd monitor on Windows settings, but now its the 1st.

I already cleaned and re-installed the graphic drivers but the problem remains.
