David,
You missed my point.
It sailed silently overhead in the flight-levels.
It is 50 million pixels of color information per second as you say, but you are using 8-bits per pixel, that is pretty shabby for a HD display.
RGB often uses 24-bits. The HDMI interface requires at least 30-bits:

So it is ~50 M pixels/s * 30 bits/pixel => ~1.5 Gbits / sec
Damn, video is just huge. When I shoot in widescreen (1280x720) the uncompressed dvi is just over 158 Mb/s. From a bit standpoint that would be 1.26 Gbits/s. I cringe each time I have to download another hour of tape. That was a good link. I still thought true-color was the biggest hog. They might as well go ahead and define color depth as 'uint32_t' and get it over with...
So a 1 Gigabit NIC can't keep up with the needs of the display even ignoring overhead concerns.
So that's probably not a good idea to try it over my 100TX segments? -- David C. Rankin, J.D.,P.E. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
