Hi all,
I have a Haswell and Radeon hd 7990 set up.
I have just purchased a Sony 55 inch 4K screen (XBR-55X900A ) but am currently unable to to set up PC UHD through the HDMI port.
Does anybody know what limitations these setups are currently presented with??

Is it a matter of having to wait for HDMI 2.0 (which the Sony will support through a hardware upgrade).
Or should this be possible for me to do now?

Any response would be greatly appreciated.
Thanks
 
You sill have to wait for HDMI 2.0 otherwise you're limited to 3840×2160p @ 24 Hz. Have you tried putting the refresh rate down to 24 or 30hz?
Does it have any other interfaces?

Thanks for helping Rossi.
I have realised HDMI 1.4a can go only to 24fps, so I will try that now.
I anticipated it would be more straightforward. I should have realized it would not be so..

... Switching to 24fps through catalyst does nothing to help my cause.
and therefore the tv is only picking up a 60hz full hd signal through the hdmi cable.


catalyst is advising the maximum resolution and refresh rate to be 1920p and 60hz.
mmm...
 
...update

Plenty of videos on the net showing the display,

None showing it hooked up to a pc though, at least not what I can find.
I'm wondering if the displays software may be at fault??
 
Update..
I have reverted to Intel Iris HD4600 Igpu and I get full 4k resoltuion,. At least now I can test out 1920p passive 3D and upscaled blurays etc.

However, no matter what AMD catalyst I try I get nowhere.

The whole reason I purchased the Screen was to ready myself for 4K gaming.

AMD, you have done well this year and I am a fan, but please don't let everyone down just as 4K starts to become mainstream.

I will forgive you if the next beta driver offers 4K support and the support for this monitor at least. The KD-55X9005A.
:-S
 
how do you game on a pc monitor which is 55"?

surely a 30" hazro or dell would have been a much better buy?

i'm all for big tv's but for pc gaming when your sitting within 1 metre of the screen, it does become pointless after 30" imo.

plus they are probably going to be much better supported res wise as well, plus you could have saved yourself a few grand.

I just watched Tokyo drift upscaled from 10 feet back. Trust me, you notice the difference.

And playing games on a large screen realaxing on the sofa is great.
Just hoping AMD fix things soon with 4k support.

Kudos goes to Intel for supporting it on Haswell.

Opps, the info from those links suggests a budget 640GT will work, maybe swap to Nvidia?

yeas but most PC monitors are used within 1 metre

I have a proper 4K clip so i know what the difference is quality wise. it just seems overkill. especially since 4K has not got an official standard yet.

More to the point I don't think 55" really needs more resolution than 1080p, my screen looks fantastic with HD content I don't think 4k would bring any wonderous gains at that size.

Just my 2c

55"-60" is about the borderline for tv 4k use , you are correct (some may be able to spot the difference but unlikely)
 
We just got the Samsung uhdtv in the office.
Looks superb in the metal..
Just need to get some uhd content on there so I can fully test it out.
Will do a side by side with a 95 inch lfd and hopefully the new curved oledwhich is due in this week too :)

Yes but in this case he is using it from a suitable distance
 
Tada!

HDMI 2.0, which is backwards compatible with earlier versions of the HDMI specifications, significantly increases bandwidth up to 18Gbps and adds key enhancements to support continuing market requirements for enhancing the consumer video and audio experience. New functionality includes:
• 4K@50/60, (2160p), which is 4 times the clarity of 1080p/60 video resolution
• Up to 32 audio channels for a multi-dimensional immersive audio experience
• Up to 1536kHz audio sample frequency for the highest audio fidelity
• Simultaneous delivery of dual video streams to multiple users on the same screen
• Simultaneous delivery of multi-stream audio to multiple users (up to 4)
• Support for the wide angle theatrical 21:9 video aspect ratio
• Dynamic synchronization of video and audio streams
• CEC extensions provides expanded command and control of consumer electronics devices through a single control point
HDMI 2.0 does not define new cables or new connectors. Current High Speed cables (Category 2 cables) are capable of carrying the increased bandwidth.

I'm attending IBC in Amsterdam next week (I work for a large TV/Set Top Box manufacturer) so I'll be sure to get any interesting pics for everyone ;).
