Been thinking of the monitors for this game and also the 4p PS3 Gundam Extreme VS Full Boost setup.
GSD (System 2x6) runs at 480p, Full Boost runs at 720p.
Most arcade games of that era I'd run on these setups are also actually 720p.
Originally I was going to get 4x 1080p 24" TN Gaming Monitors, pros: cheaper, smaller and easier to transport.
But then I realised that 1440p is a truly magical resolution, we're talking integer scales of both 720p and 480p.
So, 4x 1440p 32" IPS Gaming monitors, pros: magical image. Cons: Double the price, wont be transporting anywhere, takes up heaps of room.
