More monitor advice please, greatly appreciated
on Dec 1, 2009 at 8:07:17 pm

I've been trawling freecycle for CRT monitors, I got one but was told on here that it wasn't that great because it didn't have phosphor (ps no idea what that is!).

I don't know what's what as far as monitors are concerned and I simply cannot afford a new monitor at present at any price, hence me looking on freecycle.

so below I've pasted the specs for the next one I'm going for (Fujitsu Siemens C-700) it has phosphor 22; is that good? Your advice and comments would be greatly appreciated.

Many Thanks

[Roli Rivelino] "I've been trawling freecycle for CRT monitors, I got one but was told on here that it wasn't that great because it didn't have phosphor (ps no idea what that is!). "

Someone was confused. All CRT monitors have phosphors. Phosphors are the small individual elements in a picture tube that light up red, green or blue when they are struck by an electron beam from the CRT gun/guns. What they probably meant was SMPTE-C phosphors, which are the standard for professional broadcast CRTs.

What's your reason for wanting a CRT anyway? If you need a CRT just to check for SD field order and artifact issues, then any CRT will do. If you want accurate color rendition for color grading, then you'll have to spend some money, even for a used monitor. Sony's PVM and BVM series are the standard, but only the more expensive models have SMPTE-C phosphors.

At this point, it's kind of silly to spend a lot on a CRT unless you happen to find a really sweet deal on an unused B-stock model or something used with very, very low hours on it. eBay always has some decent PVM and BVM monitors, so check there if you're in the market.

I just checked out your older post in the Color forum so now I have a better idea of what they were telling you. They said "aging phosphors," not "no phosphors." The phosphors in a CRT lose brightness as they get older, so an older CRT is harder to calibrate properly.

They also referred to the fact that you don't have a calibration probe, which is an optical sensor device used in conjunction with calibration hardware or software to measure light output from the screen and make adjustments to bring it into spec. All of this type of equipment is very expensive, not something you're going to find on freecycle.

You're going to have to face the reality that if you want proper color rendition, you have to spend some decent money to get it. You can't use an old computer CRT, it doesn't work like that. The bare minimum you could get away with would be a used Sony PVM series CRT for SD. To get into HD, you're looking at $2500 or more for an entry level broadcast LCD like Flanders Scientific. If you really want an HD CRT, you're going to have to spend $1000 or more for a used Sony PVM-14L5 or PVM-20L5.

From the sounds of it, this is a computer monitor. If you're looking for a broadcast quality video monitor, this isn't it. Not even close.

I now know the difference between computer and broadcast monitors :-) thanks guys, I think I'll wait till I really need one.

many thanks
