Hi, I'm new to the site as you can tell. I have a question: Does anyone out there own a CRT TV that supports progressive scan? Right now I have a JVC AV-27F485 and I love it, except for no prog scan

I didn't even realize it at the time I bought it. So yeah, I'd like to know if any CRT TV's can do progressive scan.

My Philips 32PW9520 can do progressive scan when i put a NTSC dvd in my

dvdplayer.


I have not try this with a xbox (old version) but that's also possible.


Greetzzz

Holy cow man, you missed the boat. 480 Progressive scan is almost ancient history now. CRTs are just about history as well. There's only one CRT I know that is sold new that can do progressive scan, and that is the Samsung 27 inch slimfit HDTV. Any CRT HDTV can do progressive scan. There were some models that came out called EDTVs, but due to their extremely poor marketing and timing, HDTV quickly squashed these EDTVs. It probably would have helped if they had called them PSTVs as in Progressive Scan TVs. Most people who bought progressive scan DVD players thought they were getting progressive scan on their SDTVs.


Well in short. Even though progressive scan was the most significant jump in picture quality from 480i, 480p was quickly phased out by the HD revolution. No modern flat panel display is capable of doing interlaced picture. If the signal received is interlaced, flat panels will convert it to progressive in order to display it. I have a Sony KD-34XBR970 CRT. If you still want CRT, I suggest you look for one of those. It does 480p and 1080i.

Hehe, I missed the boat on purpose


The main reason I still want an SDTV/EDTV is because I play a lot of music games by Konami like IIDX. With a HDTV, the timing on these games gets throw way out the window. My friend has this problem and that's how I discovered it. Another reason is that I don't have a HD box to get HD channels so if I got a HDTV, the channels I get now would look bad. Please tell me if I'm wrong but with a HDTV, it if receives an interlaced signal, it has to deinterlace it for to display and this hurts image quality right?

Speaking of music games, I play guitar hero 1 and 2. Even though guitar hero 2 is equipped with an adjustment for digital lag, guitar hero 1 does not. My XBR970 has no lag problems on either of them. The Samsung I mentioned above and the Sony I own both support progressive scan. They do not support 480i in the same way though. Meaning that it's almost simulated interlaced. The only drawback to this is that you can't play Duck Hunt or any zapper game by Nintendo. Big deal. Even though these two TVs are HD, you will experience absolutely no lag if you are sending a signal in progressive scan. CRT TVs have two native resolutions. 480p and 1080i. Unlike flat panels that only have one resolution, either 720p or 1080p. Flat panels must do two things to display a non-native resolution. Lets say you are playing N64 which runs in 480i. You have a 720p HDTV. Your TV must de-interlace the signal (make it progressive) and then up-convert the resolution to 720. If you are playing Gamecube in progressive scan, the TV doesn't have to de-interlace, but still has to up-convert in order to display the picture. These one or two extra steps take extra time and cause lag. Some TVs are better and faster than others with this process. However, a HD CRT runs progressive scan natively. So there is no up-conversion needed therefore no lag.


My buddy bought a Samsung 5054 plasma a few months ago and I got to try old school games out on it. I was extremely impressed. Some of the graphics in motion had some jaggies, but that was about it. I didn't get to try any time sensitive games on it, but for what I could see and feel that there was no lag present. Some flat panels are getting alot better looking and are having alot less lag.


About your last question about de-interlacing. Yes, this is the most likely stage where SD pictures will turn to crap. However, it's nothing different than what a DVD player does that can do progressive scan. If you buy a crappy progressive scan DVD player, your picture will not look as good as a good progressive scan DVD player. A TV that has a crappy de-interlacing will look bad. Also if the TV has a crappy signal converter that converts all lower and higher resolutions to it's native resolution, it will not look as good as a TV with a good one. If both of these are good, then your picture can be just as good if not better than a CRT can provide. I wouldn't search for a CRT EDTV unless you wanna buy a used set. You'll be able to pick up a HD CRT new and get all the benefits of progressive scan and playing games in 480i with no lag. Plus get to watch the game in 1080i. Either that or just wait and flat panels will eventually have no lag.
