Most TVs come out of the same chinese factories.  The only difference between them is whether they had a DVB/T or ASTC tuner in them.  With VGA it shouldn't matter.


Oh, but it does!  The Minimig core is PAL and the TV needs to sync at 50Hz in order to display it.  Back in the early days there was a 60Hz PAL core, but it was later dropped (I know, I tested it).  The net result is that if you live in the USA you CANNOT be 100% certain that your LCD TV or Monitor will display a PAL Minimig screen.

It is for this reason when I send anyone a preconfigured Minimig HD setup that I always set it for a NTSC Workbench mode.  They can test it on a PAL mode and then save it if it works.

So, if you're buying an LCD TV or Monitor then simply check the specs and look for 50Hz.  I've had good luck with Viewsonic models, but you have to check to be certain:

For example, look at this one which states a vertical refresh rate of 50Hz-75Hz.  This one would be good for PAL and NTSC

However, this one just states a 60Hz refresh rate:
