I’m using SDL 1.2 on a small embedded device running a derivate of Debian Jessie. The device has a TFT with 480x272 screen size.
The problem is that SDL only reports these supported screen resolutions:
(1600, 1200) (1280, 1024) (1024, 1024) (1280, 960) (1152, 864) (1024, 768) (800, 600) (768, 576) (640, 480)
Since my desired resolution of 480x272 is missing, the next higher one 640x480 is used, and my application is scaled down and centered on the screen, leaving a big black border all around. Since the screen is already rather small it is not usable this way.
How can I get SDL to support 480x272? Is the list of supported resolutions compiled into SDL, and if not, how can I modify that list without rebuilding SDL?
I’m using the standard SDL 1.2 Debian package. Actually I am using it indirectly through pyGame, but after looking at the pyGame sources and writing a little SDL-test in C I realized that the problem stems from SDL, not pyGame (pyGame is build upon SDL) - my SDL test shows the same defect. The hardware I’m working on is a modified Raspberry Pi 2 (the device is called an Armadillo 43T).
Thanks and best regards,
