You are right, I really just need to get a 20" PVM and maybe get a separate monitor.
Still, since you have the OSSC I would like to know if you tried hooking up a Wii to it? I really would like a better option and I have a lot of old VGAs and several new TN and IPS LCDs available to me. So I can experiment with things till I am happy if you think the line doubling works well.
I am on the waiting list for the OSSC (but already have a XRGB-Mini) with the hopes that it could be a good solution for some of my edge case issues.
I've been trying to find some direct feed of Wii to OSSC but I am having issues finding anything that isnt' off screen filming.
Yes I tried my Wii on my VGA monitor and an LCD monitor. My opinion is that compared to my PVM it looked awful on the LCD and whilst Ok on the VGA monitor nowhere near as good as the PVM.
I think it's because Nintendo games are very colourful and therefore very suited to a PVM with it's bright screen.
I also have a nice Plasma TV and so have checked out component 480P, but I'm happier playing Wii and GC on my PVM on RGB at 480i, I think it looks better and is the best solution for me.
