Optoma HD65 LBX is not working on SD sources


Edwij Bont

When i have HD sources (computer, hd videocamera) connected to the HD65, the LBX mode stretches the image vertically.
But when i have a SD source connected, like my satellite tuner, LBX is doing nothing, it's just the same as 16:9 mode.
Is this normal?

I have contacted Optoma customer service international and the Dutch dealer but they just read the manual for me, useless!

I really want the LBX mode to work when watching satellite tv because some stations broadcast 4:3 letterbox while the content is 16:9.
With the LBX mode I could stretch the image to fill the screen.

So please could anyone tell me if the LBX mode is stretching the image vertically when an SD source is connected or is it just the same as the 16:9 mode?
