AMD Radeon outputs only 1080i (1920x1080@30hz) on Full HD TV

Question

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 1920x1080 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 1920x1080 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 1680x1050 60hz stopped working. SO now max 60 hz resolution I Can get is 1600x900 60hz... Everything above works on 30hz only. Same with 13.12 drivers..

Solution

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.

is running 1080p and 1080i that big of an issue for you? you can actually see a difference? i find it hard to believe you can.

You probably didnt knew.. but (1080i) 30hz refresh rate means that TV wont display more than 30 fps... Do you think I bought r9 270x to play games on 30 fps? :)

just a nitpick, but 720i is "full" HD. You just want 1080p

The needed resolution IS listed in settings and IS shown as available. However when I switch to it Im getting black screen with HDMI not connected error.

Just check in your tv setting, if there is a gaming mode, turn it on while switching resolution. In my Toshiba TV it was there named noise reduction. According to my knowledge, The Full HD TV have some image Post processing job, so the tv processor decodes every single frame. This job can't be done at high resolution because these processor are not so powerful. So turning off this post processing may solve your issue. Please note that this kind of setting varies from tv to tv, model to model. Usually they can be found as gaming mode or nose reduction.

Tried all possible formats. Still no use.
