Got a 32" Samsung LED TV and it doesn't work with the 'out-of-box' IndivisionAGA settings. I had to tweak the Indivision config to get it to display an image for PAL screen modes even though my DELL 2405FPW handled it straight away.
If you're just after a flat panel to display 15KHz without needing a scandoubler the BenQ G2420HD (24" 1920x1080 panel) works fine through VGA and displays my bog stock 500 with no issues at all (stretched to fit)
