De-stretch with a multiplier and then calibrate. You need to map 520 back to 480 and lose some pixels in the process.
Some Android devices (Chuwi 8) have massive reported distortion. So a calibration screen is necessary since you cannot figure it out by querying the GPU. md On 4/19/2016 12:30 AM, Callum Coe wrote:
I’ve an embedded device with a physical screen resolution of 800 x 480, but the pixels themselves are actually wider than they are high. The entire GUI therefore appears stretched, so it looks like a 800 x 480 GUI stretched to fill 800 x 520 screen. How am I best to handle this, so my GUI does not appear wider than it should?
