HDMI 1280x800 on UDOO QUAD / Android

Dear All,
I bought this LCD monitor able to display at 1280x800@60 (I tested it as external hdmi screen and it worked with 1280x800@60):

Using U-BOOT I set the env in this way:

Code:

setenv bootargs console=ttymxc1,115200 init=/init video=mxcfb0:dev=hdmi,1280x800@60,if=RGB24,bpp=32 video=mxcfb1:off video=mxcfb2:off fbmem=28M vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale mem=1024M

and then

Code:

saveenv

Nevertheless the Android boots at 640x480@60 regardless the setup.
This is what happens at kernel boot:

Code:

MIPI DSI driver module loaded
mxc_sdc_fb mxc_sdc_fb.0: register mxc display driver hdmi
mxc_hdmi mxc_hdmi: Detected HDMI controller 0x13:0xa:0xa0:0xc1
imx-ipuv3 imx-ipuv3.0: IPU DMFC DP HIGH RESOLUTION: 1(0,1), 5B(2~5), 5F(6,7)
mxc_sdc_fb mxc_sdc_fb.1: Can't get fb option for mxcfb1!
mxc_sdc_fb mxc_sdc_fb.2: Can't get fb option for mxcfb2!

Any suggestion?

Thank you for the answer.
Unfortunately doesn't work.
These are the messages at boot:

Code:

Update:
I tried with the M specification and even using 1280x720 with no results.
Is it possible the resolution is not supported by Android 4.4.2 ?
The monitor works perfectly with the UDOO Neo on both Linux and Android 5.
Now I'll try the UDOO QUAD with the latest Linux.

Update:
Apparently it is a Android 4.4.2 limitation: using the latest ubuntu by udoo the monitor works perfectly with really remarkable results using the Udoo QUAD.
I hope the next Android version for Udoo QUAD (when will be available) will fix the 1280x800 resolution.
