SOTN looks amazing on everything. The world needed (needs) more games like that.
PVMs are not the end all be all, and I urge people in this thread to check out other brands. Yes, I use a PVM, but also love the Panasonic BT line and would prefer to own one of those if I could find a 20" model. What I would recommend is to focus on getting something that you think looks cool, because in the end, it's really all subjective.
Sometimes it's not so subjective. I was excited to start Mario RPG after acquiring it from a Gaffer... it looks pretty bad on my BVM. That probably goes for a bunch of games with low-res prerendered assets on a sharp CRT (eg. Resident Evil). N64 looks significantly worse on a sharp tube with thick scanlines. The built-in blur filter's ugliness is somehow amplified and the PQ takes a hit. Fine sprite work loses some of its intended shape due to the razor thin and widely spaced out lines... starts looking like a collection of lines and less like fully realized, lively sprites.
Edit: I've never seen Panasonic pro CRTs past 13" for sale anywhere, although they do exist. But if you want one, some of the 2000s 15-20" JVCs are identical to the Panasonics. And the 20" Ikegami TM20s use Panasonic tubes.
IIRC You have a 14M4U like me correct? That little thing is awesome.
14L2, 600TVL. Just sharp enough, visible but thin lines, fantastic color. All games look good on it.
How would I know what has a high resolution tube?
Note the model number on the back and look up the specs on your phone. You want to pay attention to the horizontal resolution (television lines or TVL). Old CRTs and PVMs are 250-400 lines, mid-tier CRTs are 500-700, high-end PVMs and JVCs are 750-800 lines, BVMs are 800-1000.
Tuning the focus of a BVM can give you the right amount of sharpness for your
scanline-taste which may fall between a BVM and PVM. So it doesn't need to be
one or the other.
That would require opening up most monitors, correct? (Seen a couple with a focus pot on the back of the case). I'm also not sure this has the same effect as a lower TVL, nice quality monitor. It's more nuanced than having an overall blurrier picture or else we'd be clamoring for consumer sets with blurry, worn out tubes. As an example, my 20M4U at 800TVL has thicker lines and is blurrier than my 600TVL 14L2 with thinner lines and overall crisper picture. I also have a tiny 300TVL PVM with a completely different picture quality that you can't obtain by blurring the bigger, higher-res monitors.
