Graphics Card: AMD Radeon r9 270x
Screen : Samsung F5000 series 32 inch LED Full HDTV.
Cable : HDMI cable connected to my graphics card's HDMI slot, and to my screen's HDMI slot.
OS: Windows 8.1 x64
The max resolution I can set and still see screen is 1920×1080 30Hz…
In CCC driver settings it shows that TV is capable of full HD 1080p 60hz (and I know it, because I can easily connect my NB with GT540m with no problem) and it lets select it, but when I set this setting, TV shows that there is no signal or Resolution not supported (Actually it auto sets 1080p 60hz after Catalyst driver install so I had to boot windows in low resolution mode to change that 1080p to something lower) . Hovever everything works just brillian (1080p 60hz) just after fresh windows (8.1) install until at least windows native amd display drivers are installed. Any solution how can I use proper Full HD with this graphics card? As clearly 1920×1080 30hz is totally unusable so Im currently running on 1680×1050@60hz which is not what I paid for.
UPDATE:
After Driver update to 14.1 beta (was using 13.10) even 1680×1050 60hz stopped working. SO now max 60 hz resolution I Can get is 1600×900 60hz… Everything above works on 30hz only. Same with 13.12 drivers..

Inside the catalyst control center, there is a options to add the resolutions which are currently unavailable, add your required resolution with refresh rate, then apply it.
