The TI Android distribution uses the old linux kernel 3.2. I believe this has issues with some displays. Have you tried the tips mentioned in the User Guide? http://processors.wiki.ti.com/index.php/TI-Android-JB-4.2.2-DevKit-4.1.1_UserGuide#Using_HDMI_Display This kernel configures a fixed resolution and it is not possible to change the HDMI output resolution without recompiling the kernel. -Vishveshwar > Regards > Bishan > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
