Rockchip RK3288 - Not true 4K picture/video?
If you Google rk3288 not really 4k, the first result shows an article or investigation about whether RK3288 really ouputs true 4K.

Title
Can Rockchip RK3288 Android TV Boxes Play Videos at True 4K UHD / 2160p Resolution?


Can someone confirm or deny these results?

Please, could you point to where this has been clarified on the XBMC forum ? I am about to purchase the Open Hour player, but waiting to confirm it can output true 4K resolution.

The 4K Video will play in 4K resolution in Open Hour Chameleon.

To read 4K pictures 1:1 with Open Hour you can install other software on the Google Play Store
https://play.google.com/store/apps/detai...c&hl=fr_FR

For video See my tests here with the Open Hour
http://forum.openhourlab.com/showthread....61#pid3761

Conclusion beware you incomplete tests and see elsewhere

Of course not - the Android "desktop" can't be configured to a 4k display resolution resolution* - Apps not aware of the special GPU (like the Rockchip player) can make use of the "native" Android display resolution only.

*of course I can have missed something here

Yes you are right, if a App is made for 720P or 1080P then it will not give you a 4K resolution, it will then be upscaled to 4K, so not real 4K.

the app claims full screen on 4K if you set the android resolution to 4K
