So I have:
(1) Roku HD (bought 2 weeks ago)
(2) 2 laptops + 1 NAD DVD player, all with HDMI outputs
(3) a Sanyo 720p LCD TV with HDMI inputs (bought in 2007)
(4) a newly-bought Toshiba 50L2200u (50", 1080p)
(5) 1 good HDMI cable
The problem is that my my Toshiba can't recognize Roku HD. When I power up the Roku, the Toshiba displays the purple Roku logo, then says no signal. My Roku works with my old Sanyo LCD TV via HDMI, my Toshiba works with all my laptops and DVD player via HDMI, and I only used one HDMI cable. So it seems that everything works, but that somehow the Toshiba and the Roku are not compatible. Any ideas?
