Have been using -
i3 2105 (Sandybridge),
and Win 7HP on a Samsung LN40A550 via HDMI for some two years. Works very well.
Curios for Windows 8.1 and I have now made a fresh, UEFI install. A few minutes into the second boot (I was entering the WMC add-on code) the screen goes blank. TV reports : "No Signal". Reboots would display the POST and Windows loading screen, but blank at login. I took a D-Sub and I now get a picture.
Used this to install the latest HD3000 drivers for Win 8.0 from Intel's website. HDMI works now, but at 640x480@60Hz (I didn't know so low was still possible). Changing to a higher resolution gives blank screen. turns out, the driver was sending at 59Hz which my TV does not understand. Changed it to 1080p@60p and all is well.
I now go to WMC to configure my network tuners. Works great until I fullscreen WMC. Then all goes blank and I need to shutdown and reboot. What is wrong here? No problem when I plug the D-Sub back.
The system is still fresh. No drivers installed apart RST and IGD.
All input appreciated.
