I have a tablet with Windows 10 on it. It has an Intel Cherry Trail processor with integrated graphic card. I installed several games on it (Warcraft 3, C&C: Generals, NFS: Most Wanted, UT2004, DOOM 3, Flat Out 2, Counter Strike 1.6). While some of the games (Flat Out 2, NFS: Most Wanted, DOOM 3, Counter Strike 1.6) run fine, the rest of the games is trying to display in portrait mode:
I have not been able to find out how to fix this. Only option is Windowed mode with Warcraft 3, but the tablet can't handle 2048x1536 resolution fluently, so I would have to change my desktop resolution anytime I want to play it. Also you can not really move around the map in the game by touching the side with mouse, as it is in windowed mode.
Funny think also is, that it displays rotated, but the controls (or touch input) reacts as it is displayed correctly. From my investigation it seems to be DirectX 8 related problem and that games that runs on higher DirectX are ok.
I also tried compatibility mode, disable scaling, different resolutions but without any success. Since I did not found the solution I decided to create this question.
EDIT: My girlfriend bought this netbook recently. It has the same processor as my Onda, so I tried some game on her tablet. I actually only tried Warcraft 3, but there was no problem with screen rotation. So it might be an error specific only to my ONDA tablet, or maybe I have some bad GPU drivers or something like that. Still no sollution though :(
