[rickchu]

Hi,

Can any one share HDMI 1920x1200 parameters in iMX6?

In current source codes does not have 1920x1200 resolution support yet, need help to this feature request.

From "VESA and Industry Standards and Guidelines for Computer Display Monitor Timing (DMT)" specification, DMTv1r11.pdf, there are some 1920x1200 timing parameters, maybe you can use them.

Hi,

I couldn't find DMTv1r11.pdf file. Could someone share 1920x1200 HDMI parameters (mxc_cea_mode item) to add in mxc_edid.c kernel module?

thank you, regards

Andrea

Hi Rick,

Note that you'll lose audio support (or it won't operate properly) since the mode isn't one of the standard "CEA" modes supported by the driver:
