Hi, ChiaChen,
Thanks very much for your help.
I tried the dfblayer command as you suggested, and here is what I get.
Is that means the underlying graphics plane can only support up to
720x576? Is this a hardware limitation or other driver software? I am
just wondering if is there anyway to change it. Thanks.

Hi, Xie, Weihong (NSN - US/Redmond),
You could try "dfblayer" in the terminal.
To get how many layers you can use:
#dfbinfo
To judge the resalution it supportted or not:
#dfblayer -l 0 -m 1024x768
0 is the ID of the layer, if it has mutiple layers, the ID should be
0,1,2....
Best regards,
chiachen

We are using directFB on an EIP settopbox. It runs fine for resolution
720X480, but when trying to change the resolution to 1280X720, it gives
the above the error. Here is the complete log, anybody has any idea,
thanks.
