This would be the highest line count 9/10" tube I've ever found. It's service manual states 450+ TVL, so that means more than 450TVL. The next highest tvl (total vertical lines, or TV Lines) would be the HR trinitrons, for example the PVM 8044Q, and those are labeled as 450TVL.
The more lines the sharper the image can be, or the more detail can be resolved out of smaller size on the image. TVL is a little bit hard to explain, so feel free to look it up if you want to learn more.
But this set is 450+TVL, and I've seen monitors with the same tube marketed as 500TVL, so that's just insane for a set this size.
Plus this monitor uses a dot mask, not slots, not aperture grille stripes, DOTS! That's also just unheard of on a set this size. I've literally never seen it anywhere else aside from these exceptionally high quality Ikegami sets.
Now that we got how incredibly unique, and top of the line this set is I can also tell you another reason why it's great. It offers all the input options. Composite, S video, Component and RGB! How great is that!
Also, this monitor has a bottom tray piece screwed into it, that's what that metal frame thing sticking out the back is. I think it was probably used to help it mount into some rack at some point. I just left it on, because I think it helps give it even more structural integrity. The piece I'm talking about is sort of bent up a little bit too, but it's not even a part of the monitor, and can easily be removed if you wanted to.
No on screen menu, so all the geometry adjustments are inside via pots, which isn't that bad. You can see in one of the photos I have it opened up, and all the adjustments are on that board which folds out. And I did adjust it the best I could for mys setup. The inside of this set was super clean. I did notice a teeny tiny burn in in the corner. Now in normal every day situations, I would have never even noticed the burn in, but if you take a black light out, the ultraviolet light helps illuminate burn in, and I can make out a number 4 in the top left corner. You can see in the picture of the solid white on the screen, you can kind of see it in the top left corner.
There's also a teeny tiny mark on the glass, I zoomed in on the glass in one picture, but it's so little I can't even see it in the picture. I just wanted to make sure I said something about it though.
If you're looking at the monitor straight on, the bottom left plastic corner is broken. I have the piece of plastic so if you want, you can try to glue it on some day, or just leave it as is.
Overall just a very unique monitor, I love it for what it is.
