my old pc had Radeon 6870. Had no Problems with Video or Audio output on a Samsung LED-TV.
Before a week i build a new Pc with XFX-R9-280x #extreme happy . I can see an Output during Booting. But loosing signal right before Windows-Login-Screen appears. ( Windows 7 64Bit ).
Ive tried this with every resolution. But i always loose signal at login screen. Tested with the last 2 Catalyst Versions.
Ive tried alot of other settings, options and third party softwares without any results.
Maybe somebody had the same Problem or have an idea where the problem might be?
My new System:
i5 4670k, xfx r9 280x, 8gb kingston hyper-x, asus z87 gryphon, corsair 850watt ps, windows 7 64bit. Everything else is the same like on my old system (cable, distance, resolution, ...).
You would make me happy with any small advice or an idea
Until than i will continue experimenting.
Marry Christmas and Happy new year!!
