Hi all,
I have an VGA displayer connected to my board , I want to output 1366x768 resolution on the displayer. In mxc_edid.c file I've add the lines:
{
NULL, 60, 1368, 768, 12232, 274, 48, 17, 2, 32, 5,
0, FB_VMODE_NONINTERLACED, FB_MODE_IS_VESA,
},
When I used this resolution the displayer display 1280x768 resolution I think there are some wrong with the IPU drivers, Any ideas about this ?

Hi kenny
first you need to make sure that your monitor supports 1366x768,
try this from Linux command line:
cat /sys/class/graphics/fb0/modes
Note i.MX6 HDMI module natively does not support this mode,
supported modes are given in Table 33-3 Video Modes IMX6DQRM
Chapter 18 MX53UG shows how to add new resolution to VGA LCD
Connected to IPU Display Port 0 (Example 18-2), also
one needs to add kernel command line like 1366x768M@60
Best regards

Hi igorpadykov
Thank you for your reply, I use the 1360x768 reslution instead of 1366x768, the monitor display 1366x768 reslution. I don't know the reason.
