i.MX6 HDMI driver will automatically detect supported resolutions based on information stored in EDID. By configuring the kernel as described below the detected values will be ignored and custom settings applied. This can be used in case custom DVI monitors or custom LCD panels are used.
This document describes how to force these HDMI (DVI) resolutions:
- VGA -> video=mxcfb0:dev=hdmi,640x480M@60,if=RGB24,bpp=32
- WVGA-> video=mxcfb0:dev=hdmi,800x480M@60,if=RGB24,bpp=32
- SVGA-> video=mxcfb0:dev=hdmi,800x600M@60,if=RGB24,bpp=32
- XGA-> video=mxcfb0:dev=hdmi,1024x768M@60,if=RGB24,bpp=32
- SXGA -> video=mxcfb0:dev=hdmi,1280x1024M@60,if=RGB24,bpp=32
