Oculus did pick the right display device for DK2
//EDIT// Studied the forum and got over my portrait mode problem, using extended OK now and looking forward to direct mode applications. Using Virtual Desktop now, very excellent work. ---------...
There's a good post on the Pyra forums (Pyra is a handheld linux gaming mini laptop by the creators of the Open Pandora) that goes over the issues that Oculus would also be facing:

Basically, they need a landscape screen (it's an NDS style clamshell design). But the only small screens you can still get are either portrait mode or low res.
Their possible solutions:
- get a low res screen (not acceptable)
- use the rotation features of the omap5 soc, but this introduces performance problems
- do OS level rotation. Fine for desktop apps, but anything going low level will need to be rewritten to not be sideways
- use a screen addressing rotation chip. Apparently no performance hit, but the only one they could find can't handle higher than 1280x720
So they are (or at least were, I haven't been keeping up on it much recently) going with the last option.
There's just no demand for small landscape hd panels, everything is for phones. The dk2 is using the panel from the samsung galaxy note 3 phone, which is probably the best they could get at the time with all of the requirements (5", low persistence, capable of 75Hz, 1920x1080 res).
