Keep in mind that due to the age of CRTs, the components controlled by that knob (usually rubber) might have deteriorated due to heat and any movement might kill them. In my case (many years ago) it broke because the rubber ring inside simply turned to dust when I turned it and the image was permanently blurry after that.

It isn’t that bright in person, think it’s just the way the photo turned out. I’ve turned brightness and contrast lower than the medium setting of 50. I did take the photo a little further away then cropped afterwards so maybe the metering is bad. I’ll upload another shortly. The phosphors don’t appear that yellow in person, but it’s hard to tell even with my eye right up to the screen. I had the colour on warm though so I’ve set it to normal for the new photo

Yeah I download CRT pics I find online for future reference, got loads. Thanks for the link, I’ll give this a go.
This TV is in excellent condition, it’s only a 2001 model so hopefully will be fine

As the phosphor burns out over time and the tubes are basically disposable, what would be some ways to prolong the lifetime of our CRTs?
How long does such a tube last on average?
I for one always tone down the brightness to minimum when I don’t consume any content or turn it off right away, but again I don’t know if that would also somehow wear it out.
It is a shame really, those deep blacks and vibrant colors always blow me away when coming from my LCD. I could imagine using it for regular desktop usage, but that would be such a waste.

And yea, this is all I can offer right now. I don’t have the equipment available to take proper closeup shots.

AFAIK, it’s mostly just a matter of conserving hours.
There’s a process called tube “rejuvenation” that can give an old, worn tube a second life, but it’s a destructive process that can only be done once (I think).

Lovely dot mask monitor - doesn’t look that old - around 2000’s perhaps?
It says january 2000 on the back. I think it was nothing expensive back in the day, being from ‘Medion’, something you’d get at the discounter I think. At that time even cheap CRTs had quite a decent image quality it appears. Only problem I noticed is the image distorts on bright pictures because of bad voltage regulation or something. All cheap dotmask CRTs have this.

Blimey 2000 really doesn’t feel that long ago but you forget LCDs were still ridiculously expensive and rubbish at that time.

2000 PC monitors can be considered relatively new, I believe they were fairly standardized by that time. 17/19" inch size, refresh rate over 100 Hz possible, dot pitches below 0.30 mm.
10 years before, they were way smaller (around 14") and of course less capable.

We really need some good photos of a PVM displaying composite video, I’ve been searching high and low and haven’t found much.

Probably not good enough, but the comparsion between different signal types here on a 1354Q PVM is very interesting.

By any chance can someone please post a shot of the piano located in the bar of stage 1 of Streets of Rage 2? On a setup typical of the period do scanlines divide the keys?
And did somebody already ask this sometime ago? This question seems weirdly familiar.

Here’s a shot from a low TVL slot mask which has quite a soft image; no perceivable dividing scanlines on the piano keys at all. The scanlines are very thin on this set though, it might need a slight tune up…

Lovely photo! Just on the point of the scanlines - there are very visible dark gaps between the scanlines when scanning dark areas in your photo. It looks as though you loose them only in the light areas. Is this something you see in person?

Oh yes I see the scanlines in person! I meant no perceivable scanlines on the white piano keys in response to HeriticZero’s request. Sorry I wasn’t clear. I’ll update the above post to clarify

Does anyone know what this effect is caused by? It seems like there is a dim illumination from the green phosphor line even in the areas the electron beam isnt hitting.
Here’s the full image for reference

I would guess that’s just reflection / ambient illumination rather than the phosphor actually glowing.

Looks like it could be the mask wires.
