240p
 

So I am fascinated by these roundies, and have been wondering.

I may get one for myself, but I play a LOT of old video games, which only output a non-interlaced 240p signal.

But, can these old roundies and their chassis, handle these types of signals? With my hybrid in my sig, I have to play with the V-hold, but it eventually works out fine.

You should not have an issue with the older sets.
