G400 - TV on the accelerated head

Several questions.

Can You windows guys play OpenGL games on the second head ?

Under Linux only the first head is 3D accelerated (dri could be used).
Unfortunately I can't plug a TV set on the first head. It's not
initialized properly on boot, nothing is displayed on either head
if a TV is connected to the first and monitor to the second.
I could initialize the second to monitor(after blindly starting X) but the
TV connected to the first remains unusable.

I wonder if TV output is available for the first head ?

What I want is to use the acceleration on the TV(using dri for movies
and games) and the slow head connected to the monitor.

Anyone ?
