On the other hand, I found this alternative to the Samsung 12.1 panel:

which can be got for more or less the same amount as the Samsung. This is however, a MVA panel, with 800x600 res (good enough for emus, I assume), good angles, LED backlight and 1500:1 contrast ratio!
Does anybody know of a controller board that could be suitable for this panel?
Thanks!
