So since we've been talking about giant and heavy CRT displays, I do wonder just what is the largest CRT?

I am lead to believe that the largest 16x9 CRT would be 38" as RCA made a 38" CRT HDTV and as evidenced in another thread, Sony had a 38" pro 16x9 CRT. Anyone know of a larger 16x9 CRT?

I am also lead to believe that the largest 4x3 CRT is 40" or really 42" (since the overscan only allows 40" to be viewable.) The Sony KV-40XBR700/800 is a 42" tube with 40" viewable. Mitsubishi made a 40" tube TV, but I can't find too much info on it. Mitsu also made a 42" pro CRT, but with only 40" viewable.

Thus far I've not been able to find much else larger than those sizes.

What about CRT projectors?

Nah, I'm more interested in CRT direct views.

well if you do research the largest CRT projector tube is i believe 9 inches.

I was asking if we were counting projectors

I like a big picture, so I do my viewing on a 150" projector screen. Not bashing CRT but they're so damn small, you have to be sitting like 3 feet away to get a descent viewing angle in my experience. I guess this was off topic... sorry.
Long live CRT!

The Loewe Aconda was 38" and 16:9 also, I believe.

TLK

Indeed, I've read that the Aconda uses the same tube as the aforementioned RCA 38"

About 1948, RCA built a 36" round-tube set (viewable area rather less than on what we would call 36" these days). With the 90-degree deflection in those days, the tube was rather more than 40 inches deep. As a result, there was no way to fit the thing through most doors, but I'm told they sold a few to commercial operators.

DuMont made a 40 inch and Sylvania also sold it under their name - like the RCA, it was so large it wouldn't fit into most homes. DuMont used it in their presentation to the FCC on color in 1950 - they built a huge color wheel for it to show the absurdity of the CBS system with large tubes. Starting up the color wheel caused the circuit breakers in the building to blow. It really wasn't fair because the CBS system would have been able to use RCA's shadow mask color tube when it was developed, leaving the small color wheel in the studio camera. Of course the electronic tube wouldn't have overcome the severe resolution problems of CBS color or it's low frame rate and inefficient use of spectrum, not to mention incompatability with existing NTSC broadcasts.

A 42” is going to be a back-breaker! Do not attempt to move on your own! Get a friend to help!

I struggle enough as it is with a 32”.

Yep, the Sony KV-XBR800 is basically a 42" tube with 40" viewable and that one is 300+ lbs (don't ever want to have to move that again!)

Though the 38" pro tube that was discussed in another thread makes that seem light at 400+ lbs!

Of course, & I think Zworykin discusses this in one of the later editions of Television, the field-sequential system found extensive use in CCTV systems, where bandwidth wasn't as much of an issue (allowing the use of higher scan rates), but the capital & maintenance costs of three-tube cameras & NTSC encoders would have been. The Apollo missions were a special case.

I once had a Panasonic 36pd30d which was also 16:9. Transport was always a backbreaker with his 160 something pounds...but the picture was great! Sometimes I really miss it....

I think this is probably largest CRT.
It was released in 1989 Japan.
KX-45ED1


Width 1,050mm
Height　925mm
Depth　767mm
Weight 200kg
Price　2,430,000 yen

Yikes! 440 lbs!

Also says "Digital Frame Memory" . . . guess that means you can do a freeze frame if you want?

So if the yen-to-dollar exchange rate was 140 yen to the dollar back in 1989, the price would have been $17,357.14.

Now if we adjust that for inflation, $17,357.14 in 1989 is $30,998.92 in 2012! Are there any TVs/Monitors these days that approach that cost?

Apparently retails for $36,000.

Some more details here.

2nd largest I would guess this.
Released in 1989.
Panasonic TH-43K1DP


Width　1060mm
Height 938mm
Depth 580mm
Weight 140kg

No longer be called a large-screen.
Early Muse-TV.
SONY KW-3200HD


Width　905mm
Height 600mm
Depth 657mm
Weight 87kg
Price 1,300,000 yen

It seems to be progressive scan based on the EDTV standard.

My massive 36" Sony trinitron direct view CRT is a behemoth. We had to build a custom stand for instead of using anything around as it weighs near 250lbs. I got it from a free CL ad for a 32" for an old CRT only to arrive and see this beauty and wonder how in the hell I was going to get it up a flight of stairs.
