[SBE] multiviewer monitors

Hi Jonathan,
Still working on this with Samsung. I'm using their MD40B which is supposed to be a "business" grade monitor. Zooming and positioning, along with setting specific aspect ratios cut off significant parts of the raster.
Checked the SDI from the switcher into an SDI monitor, bypassing the HDMI converter, and no problems there. Switcher output is 720 x 486 and monitor says it's reading 720 x 480 when HDMI is plugged into it.
The SDI to HDMI converter is a Ross SHC-9642.
Also used the DVI input with a HDMI to DVI adapter and no change, and I cannot set the resolution there. I can only set resolution with VGA input, and that's not an option for us.
Thanks for the help.
Dave

David-
Did you find answer to this? Most consumer displays have options to a) set the input standard / resolution and b) "zoom" the picture. Can you specify which converter and TV you are using? Also, have you tried a different SDI source (such as a camera) to verify it is not the switcher output?

Hi all,
Has anyone had difficulty setting up a flat panel monitor to display a multiviewer or any other SDI output correctly, specifically the image being cut off on the edges in 16:9 or 4:3 mode?
I'm outputting a 720 x 486 multiview SDI signal from a Ross Crossover 16 switcher into a Ross SDI to HDMI converter to feed a Samsung display, and much of the image on the sides and bottom is missing.
No amount of scaling or H/V adjustments fix the problem.
Ross maintains that their converters don't do any extra processing of the SDI signal coming in, and suggest the display should be pixel 1:1 or have a "fit" mode to display properly.
Can anyone suggest a display they have had success with, or give any other ideas as to why this cropping is happening?
This monitor also has a TV tuner, and I have heard that sometimes these combination displays cut off parts of the raster to hide the ancillary space in the incoming TV signal.
Thanks for any help.
Thank you,
