Myself, I use and know the Marshall, and while the lowest resolution, I believe (if my memory serves me correctly from when I did my homework) it's the best color accuracy (please correct me if there's evidence or consensus otherwise).
The Marshall's not the most feature-rich (no scopes or 1:1 pixel to pixel), but false color is a nice facial exposure tool used in combination with the camera's WFM.
I find the 7" size to be just right, also. YMMV...
Yes, I think the LG 5.6" panel cannot produce reference quality colorimetry due to the 6-bit limitation and tiny pixel sites, TV Logic or Small HD, this is the limiting factor for color. The 7" TV Logic monitors have great color, especially the new 7" LVM-074, plus great resolution and it's very lightweight with direct access buttons for most functions, non-shiny screen, HD-SDI to HDMI conversion including 1080, all the great TV Logic scopes.
