Title:
Optoma HD20 projector recognized but no HDMI signal
Status in “xorg” package in Ubuntu:
New
Bug description:
Synopsis: I get "No Signal" and an otherwise blank screen when
connecting my Dell XPS 14" Ultrabook running 12.10 to Optoma HD20
projectors (we have two). The projector is recognized as connected.
This laptop correctly displays on at least 5 other models of external
monitors and projectors over HDMI without issue. Several Macs are
known to work fine with these projectors.
Hardware Details:
The laptop is a Dell XPS Ultrabook (L421X) running 12.10. This laptop has
Intel 4000 and NVIDIA 630M graphics, and lsmod shows nouveau and i915 drivers
loaded. This model has both HDMI and mini DisplayPort; results are identical
for HDMI and the mini DP port (with miniDP-HDMI adapter).
The projector is the Optoma HD20. This projector has two HDMI inputs
and native 1920x1600 projection. We have two of them, and all
behaviors described here are identical for both of them.

What I've tried:
When I plug the projector into my laptop, the projector is recognized
quickly as OTM 72" in Settings > Displays, but the projector declares
"No Signal" and has blank display. (Is OTM 72" right?) Xorg.0.log
shows frame buffer allocations that seem sensible based on laptop and
selected projector resolutions. Clicking "Apply" leads to the 30s
timeout dialog in which the laptop display is fine (i.e., not garbled)
but the projector says "no signal".
Both projectors work fine with Macs.
I have tried multiple cable and cable lengths.
I have tried multiple resolutions, with and without mirroring.

12.04.1 LTS behaves similarly.
Rebooting with the projector connected has the same effect.
I've tried the xrandr and gtf suggestions at

hd-graphics-ironlake/249593#249593 without success.
