Hello community,
I find myself in a strange situation:
I've got a PC with Windows 8 -MSI R9 280X graphic card- connected using HDMI to a UE55F8000 Samsung LED TV, as an extension of the main screen, which is an Acer V203H, connected using DVI.
I describe what is connected and where:
Samsung UE55F8000
HDMI 1: Set-top Box Vu+Duo2 (recognized and working fine)
HDMI 2: PC - Connectedt to HDMI port of MSI R9 280X (not working)
HDMI 3: Xbox 360 (working fine)
PC Windows 8 - Windows Update Manual installation - nothing automatic
MSI Radeon R9 280X
Motherboard Z87 G43
Main screen Acer V203H - using DVI
Extended screen Samsung UE55F8000 - using HDMI (not working)
No other wires. No antenna, no RJ45. Just power supply 230V.
This configuration for HDMI 2 has been working already some years, but yesterday suddenly stopped working.
The TV recognizes that something is connected but the screen remains black.
On the computer, on the device manager there is nothing recognized (no unknown devices)
I tried connecting other HDMI cables, but the result is the same: black screen.
I also tried connecting another PC (Laptop ACER) through the same HDMI cables, and with all of them the result was succesful.
I also successful connected from the MSI R9 280X using the same HDMI cables to another LED TV (Toshiba Rezga 32AV555DG).
I tried unplugging the MSI R9 280X, connecting the PC to the UE55F8000 through the HDMI port on the motherboard and using the integrated Intel Graphics. This connection was successful either.
So the only unsuccessful case is the connection between UE55F8000 and R9 280X through HDMI.
After this issue, I also tried updating the firmware of the TV to the latest. But it didn't solve the issue.
I also tried unplugging the UE55F8000 from the power supply many hours to discard that it was a loop ground issue. It didn't help.
I also uninstalled the drivers of the R9 280X, rebooted, installed the newest drivers again (AMD), and connected the HDMI to the UE55F8000 again. The result in this case was also dissapointing, no solution.
So, I don't understand why is issue happening, as I didn't modify any software before.
I've even formatted the C: disk (Win). After a clean reinstall of Windows 8 it's not working anyway.
Could anybody help me?
I don't know what else I should try to solve this.
I'm really desperated...
