[WeiWeiBo]

Hi everyone

I am not sure the question whether anyone met before

Here，I have a i.MX53QSB and a "MCIMXHDMICARD" which can output with HDMI signal attached monitor.

Now, I want to attached my monitors which resolution are 1280*800 & 1024*600 on i.MX53QSB using HDMI daughter card.

But from the Release note shown as the attached (file name: Release Notes r4.2 page15)，the HDMI just can support 720p and 1080p resolution

So I fonud the folder from the android source code shown as the attached (file name: path.png)

/src/kernel-imx/arch/arm/mach-mx5 

then found the "mx53_loco.c" have many video mode shown as the attached (file name: mx53-loco_c.doc  page 8~12)

Could I add additional resolution to mx53_loco.c in order to fetch my panel EDID code then show the full screen?

OR 

any method & information could provide me kindly?

thx anyone help
