Its nothing wrong of liking CRT, The war CRT vs Digital is over many years ago.
I think its still fun to see how good still a 9" can perform in 2018.
Some modifications would help some, but minimal to what its worth, and still far from a OK digital.
Tested reasontly Cine9 against JVC RS440. It was sad for the Cine9 so sad. The guy with the G90 owns a X7500 JVC and the similarity in the pictures show this easy.
say try 1080i, that is not the best option because you see the interlaced lines all the time, in my opinion 720P or 1080P 60/72hz. With 720P you can feel some higher resolution, but that is often on 8" CRTs.
1080P look like 720P anyway because of the limitations of the lenses. That I would suspect you know is max 1280x1024 with under 50% MTF if you then run 1080P you are down at 10-max 30% MTF, this is tested and documented on the net some were . "Then on the best lenses used on 9" CRTs". This will show, and very good illustrated in the pictures above. CRT has its own signature and I still like that.
nice to see that some still adore they're CRT. I might play again with my own Cine9, but I don't see the point anymore. And also in this heat here in Norway its a danger of burning down the house using it hehe
But again respect to elio and others that still only have CRT and stick by it.
