Hi,
Part of the console display is hidden when using HDMI TV.
I guess this is due to the TV over-scanning. Is there a solution to this problem?
Thanks,
Tarek

The solution for over-scanning issue was applied into i.MX Android R10.3.1 release.
The kernel patch of Android should also be able to use in Linux.
Please refer to "4.4.5 overscan" of the attached "i.MX_Android_R10.3.1_User_Guide" for more detail information.
Thanks.
- how to apply this feature
We export a property (sys.overscan.percent) to control the overscan percentage, customer can set this property to adjust the width of black border. (sys.overscan.percent = 100*h/H =100*w/W) The overscan percentage for width and height is the same, sys.overscan.percent Is limited at the range of 0~10.

would you tell me more detail about your question?
1. which board are you using?
2. which BSP are you using?
3. how to reproduce the problem on the board?
Thanks.
The board I'm using is Nitrogen 6Q Board from Boundary Devices. The BSP is version 12.08 as I don't have access to 12.09 yet. I'm running Poky distribution and using Yoctoproject openembedded build system.
The board is connected to DGM HD TV using HDMI. Any Linux image that I run (Console or GUI) I find that part of the display around the edges is hidden as if I need to down size the screen to fit into the TV display. This is a common problem and surprisingly there is Android fix from Freescale

I was wondering if there is a similar patch for native Linux?
Thanks
Usually TV has display settings for over-scanning problems.
It will be easier to change the platform than asking customers to change their TV's !
Yes, you are right. I'm not the right person to answer this question :-). Let's wait for the golden answer.
