I turned off my CRT lights in 2013. It was a good ride while it lasted and loved every minute of it!

To be honest summer is not the season of the CRT either.

I'm staying indoors mostly. I don't run much because it's 30 C and 80% humidity in here and that's at 3am

I am not dead. This post isn’t about CRTs either. What a toxic forum. I don’t want to be active on a forum where I feel guilt for not posting. Especially when 100% of posts get derailed into «it’s not worth it» «you should stop trying» «dlp is better» by the same people who complain that «crt is dead». Pull yourselves together. Instead of complaining, try fixing the problem yourself. You are all grown up men.

Hmmm


I've yet to see a DLP I liked. Board-flat, no depth or dimensionality, not drawn into the action at all. However DLP and some LED flat panels are likely the future off this hobby as only one company anywhere still makes new tubes. I am told that the Sony crystal led systems are awesome but very pricey; they are scalable to huge at about $5000 a square foot. Oooofff. Samsung just put in a massive LED system on the roof at SoFi Stadium, California, near a thousand tons worth, dang!

Here in Norway 95% of crt-users was done by 2008.

I was done in 2006. I have used a G90 for nostalgia a few years back. It was cool, and I liked the picture. But it came quite fast apparant why we do not use crt anymore. In midst of the G90 euphoria I bought a couple of unused Barco Cine 9's. I have realized that I will never use them, they will go to the recycle plant pretty soon.

Try LCoS technology. What JVC calls D-ILA and Sony calls SXRD. Been running this myself in my HT since 2013 (coming from an 8" LC EM Barco Cine 8 clone) and there was actually more depth due to the much better inter-scene contrast ratio. And my JVC is pretty old by today's standards. I did a direct comparison here for those who understand CRT: http://www.curtpalme.com/forum/viewtopic.php?t=32973

What's the best, properly calibrated and set up digital projector you've seen Tim in home use?

Kal

CRT is still highly desirable for retro gaming fans (my other hobby). I have 4 CRT monitors and I've been looking for a deal on a Sony G90 somewhere close to the NY, NJ, CT border for over a year now.

There are certain things CRT is still best for. It's ability to switch res instead of scaling everything to a fixed native res is a huge advantage. As anyone who went to Sunday school knows, scaling makes baby Jesus cry. Some CRTs can display everything from old 240p games up to 1080p Blu Rays with no scaling artifacts.

CRTs have the best motion resolution. LCD and Lcos both have horrible motion res. A 1080p or 4k Blu Ray can often look like standard def on fast moving scenes with lcd or lcos displays. They have to resort to frame interpolation which changes the look of a movie from what the director intended. Or they use black frame insertion which makes 24fps content look dark. DLP is a little better than LCOS but still nowhere near CRT.

CRT is the only projection tech to light pixels individually which allows for awesome contrast. What JVC describes as their "native contrast ratio" requires the use of wiregrid polarizer filters in the light path. Those filters help produce great black levels and OK whites but CRT has better real world contrast for everything in between.

Old school arcade light guns only work on CRT and none of the newer flatscreen compatible light guns are anywhere near as accurate. Time Crisis with a real light gun on a large CRT = pure magic.

CRT has no input lag. A flatscreen using scaling and frame interpolation can make games unplayable due to lag. Or you can use game mode with no interpolation but then you suffer motion blur...

Anyone with collections of older movie content should hang onto their CRTs. DVDs and Laserdiscs look revolting on my 77" 4k oled. You need a CRT to get an acceptable image and there are some movies that are only available on older formats. The original versions of Star Wars, for example.

Most of what I watch is still 1080p (or less) or streamed 4k which looks no different to 1080p. Given that 9" CRTs still offer some of the best image quality for 1080p and below, I'd say they aren't dead yet. They've um.... Just become more niche.... N stuff.

I'm watching Knives Out on my vintage tech, super-charged G90 and loving it. Don't write the obituary just yet.

Errr, Yes. I owned many for years, wrote/edited the hundreds of CRT projector guides and articles you find on this website, and was part of dozens of HT CRT meetings for years with CRT aficionados. I helped bring to market many of the tweaks and add-ons you're probably running on your CRT projector (such as the Moome HDMI card).

I don't understand the point of your question. If anyone's the biggest fanboy of CRT it was me for spending the 1000's of hours of 5+ years to put together this CRT website and pushing people to develop new tweaks for them. I understand and know CRT extremely well both as a fan of everything HT and as an electrical engineer who understands the technology and has worked on it at the component level.

That said, any technology has limitations no matter how you tweak it. Ignoring other advancing technologies doesn't make them go away.

i know all this and i am sure everyone is very grateful you put in this much time helping out other forum members but that doesn`t answer my question honestly.

i meant have you seen a pj 9 inch solely (still don`t understand why you had an 8 inch but ok) with the changes made on the boards to make them resolve the hd signal better and bring the noise floor down.

what`s your opinion about mike parkers mods for example on the marquee, have you seen them or his work on the g90 (though i am not sure he continued working on the g90) or gjakys work/mods on the marquee.

again kal i am not here to offend you if you feel like i did and can only applaud the many contributions you made for the crt community and still do be it to a lesser degree and wish you nothing but the best with your brewery endeavour.
