I am in the market for an HD tube and while doing research I stumbled upon this which raises a few questions:

1. Would I be correct in assuming that (720 + VBLANK)2 = 1500?

2. Will this monitor scale 720p to 1500i or will it be like 240p on a 480i tube?

3. If it does scale 720p to 1500i will the result be better than 1080i on a 1080i native tube?

4. I will be using it for 720p games. Will it lag?

I can tell you for certain, almost all of these questions require first-hand experience with this TV in order to answer. I had never even heard of this TV before today, so I reckon the answers you want will be nigh-impossible to learn without getting the tube that you have found. If, that is, you have already found it to buy. If not, I do not advise that you "hold out" for it, because a lot of these features sound like a lot of hooey to me. My experiences with other JVC brand equipment was good, so I would expect this TV to be about on par with other CRT HDTVs of its era. You are just far more likely to come across a great Sony Trinitron or other brand than this one, because as I said, never heard of this thing before today.

I was curious so I googled it. I found an AVS tread from 05 which said it was discontinued then.

I googled myself, and found this user who connected this TV to a computer. The maximum resolution reported was 824x464, which is in fact less than the 853x1080i of a Sony HiScan HDTV, and much less than the 1440x1080i of a Sony Super Fine Pitch HDTV.

I'd probably get it if I saw it somewhere cheap, but then, I'm a crazy CRT collector. If I just had to get one, I'd get either a Sony Trinitron, or an LG 30FZ4D. But then that is kinda supposing that I can just pick and choose, finding any CRT in good condition is getting a lot tougher as so many people love to shoot them with pistols or dump them on the side of the road regardless of working condition.

I would be shocked if that was right. I don't expect it to fully resolve 1280 × 720, much less twice that, but 824 x 464 is dismally low.

I haven't found one yet, and am beginning to wonder if I have a realistic chance of doing so. However, the Goodwills around here are littered with cathode rays and Super Fines pop up from time to time, so holding out for awhile is not a problem.

Well, I would be shocked if the JVC is higher than these specs, especially considering how many testimonials we have for the high-end Trinitrons through the years. Good luck in your search but there is little chance that their "1500i technology" is anything more than a marketing gimmick term.
