And it's very small screen which is a huge issue. The is no way I'd go back to such a tiny screen. Even a 27" LCD and the comparable ultrawides only have a 13" tall screen... the fw900 22.5" viewable and is only around 12" tall. Triniton CRTs also have aligment/damper lines in them. The FW900 also has convergence issues, focus issues - having to crack open the massive high energy capacitor and electronics laden chasis to tweak internally to keep tight as the settings "loosen" . Lack of per pixel cripsness as they age ("fuzzy/blob edges" like playing consoles on an old CRT TV)... They age into blooming and/or fading over time as they age and there's nothing you can do about it (without replacing parts or the whole CRT) until they eventually die. Also power suck on startup and a blast like a EMP, they are very sensitive to electric noise in the lines, sensitive to magnetic interference (like speakers) and have other issues like radiation, eye fatigue, and no HDR and HDR's much extended color volume pallete which will be more important as time goes on. Also potential signal support considerations from gpus. They also have a fairly long warm up period before their full saturation, contrast, and sharpness are their best again after they've been off or in standby.
So I wouldn't call them perfect by a long shot. What they do have is 1px of motion blur for essentially "zero" blur during high speed FoV movement / controller panning / camera movement but that is a lot of tradeoffs.
At 120fps on 120hz LCD/OLED you get 50% blur reduction down to a "fuzzy" vibration type blur during FoV movement now instead of the smearing blur you get with 60hz and low frame rate gameplay scenarios. That up to 8ms/8px of "fuzzy blur inside of the lines" is most evident when moving the FoV at high speed so how much clarity is lost is in relation to how fast you are moving your FoV around at any given time. It's also depending on staying at 120fps (solid). At different frame rate spans of frame rate averages, you aren't going to be staying at the 50% blur reduction (vs 60hz baseline) level or motion clarity.
You're talking worn FW900s. CRTs when younger or less used just basically work. At least for casual usage. Back in the day, there didn't use to be a forum like this filled with endless frustrations I don't think. Sometimes someone would get a lemon, but generally computer displays just kept getting better and better similar to other advances in computing. And then suddenly, it became more about weight and thinness and raw PQ and motion quality took a back seat. Years later and for enthusiast usage it still sucks and so awfully so that that happened. It is kind of fun that the gaming press has apparently rediscovered CRT more recently, but it's kind of too late now.
That said, OLED is awesome. Hopefully they get the incompatibilities sorted. Is the BFI really not usable? I don't mind it being darker. However, it not being available in some games modes or adding input lag is a thing?
