Dear all,

 

i have seen that in 3-14 imx6 kernel,  the mode 1280x800 for hdmi (have Adafruit hdmi lcd with this mode) is no more supported. Kernel allows only cea mode 1280x720.

 

Setting 1280x800M60 in kernel boot params,

 

Kernel 3.11 was still allowing 1280x800 reso:

[system@localhost ~]$ cat /sys/class/graphics/fb2/mode

U:1280x800p-60

 

while 3.14 not, so i ged a stretched image in the hdmi display

[user@localhost ~]$ cat /sys/class/graphics/fb2/mode

S:1280x720p-60

 

If i set 1280x720M60 as kernel params, nothing changes. Every help is appreciated.

 

Best regards
