Hi Mythili,

Try looking in sub-directories under /dev/screen/<process id>. Where process id in the case of a gles2-gears application would be as follows:

pidin ar | grep gears
176156 gles2-gears

And you would look in the sub-directories under /dev/screen/176156/...

Hi KB,

The only available file in /dev/screen/ is dpy-1.

Hi Mythi,

Have you read through the trouble shooting section (pg 169) in support7.qnx.com/.../Screen_Developers_Guide.pdf

Is the expected HDMI content visible on the HDMI display?
