I made an interface to connect a custom screen via the HDMI. The screen resolution is 320x240.
The minimum resolution of HDMI is 640x480, but option
Code: Select all
framebuffer_width = 320 framebuffer_height = 240
in the /boot/config.txt file can reduce the resolution of the system.
But my problem is there is a sort of anti-aliasing applied during the up-scaling between the system 320X240 resolution and the minimun 640x480 HDMI reslution. Making the image blur, and not really exact.
Is someone know if there is a way to have a simple pixel doubling, and not a smoothing ?
Thank a lot !
