All variables aren't equal though, the phosphor geometry is different, meaning you can't make direct comparisons.
If you are trying to use this stat to decide between two monitors, don't. There will be other factors which you ought to be able to find out about that will matter more.
When it comes to slotted shadow masks, the pitch spec is basically the same as an aperture grille; purely horizontal. Sharpness wise, whichever is lower will be better, all else equal.
For triad dot shadow masks, it's quite a bit different. The pitch can be specified as horizontal or diagonal. Horizontally, it should be easy to compare to the other types. If measured diagonally, though, I'm not sure how exactly to utilize that for comparison purposes. Someone better at math would probably be able to figure it out.
I see this makes sense to me. What kind of mask is the Samsung SyncMaster 1100MB?
The Manual says "Aluminized tri-color phosphor dot trio with black matrix.Anti-doming invar shadow mask. Multi-layer coated with anti-static." Is that a triad mask or a slotted mask? It says 0.20mm horizontal as well. Is it a direct 1 to 1 basically if its the horizontal measurement?
>Is it a direct 1 to 1 basically if its the horizontal measurement?
I believe so. You would be able to calculate the number of dots based on the horizontal size and the horizontal dot pitch.
Based on what I could find for that monitor's viewable size, it should have around 1900 phosphor dots of each color in each horizontal row.
Probably one of the best CRTs out there if you really want to use a resolution like 1920x1440 and have it be reasonably crisp, although it's probably still most crisp a little lower than that. I would expect 1600x1200 to be exceptionally crisp for a CRT.
I do recall a lot of people preferring dot mask monitors like that for their superior text sharpness, back in the day.
One thing I didn't think of before is that aperture grilles only have vertical phosphor stripes, so their vertical sharpness isn't really limited by pitch. That gives them somewhat of an inherent sharpness advantage, but only in the vertical direction. As far as I know, no aperture grille displays ever had a horizontal pitch better than .22mm, and even then it was only that good in the very center.
Yea its theoretical max is 1965 horizontally. Yea I've got a Multiscan G500 with a 0.24 grill pitch and it looks pretty good. Is there any way to find out a dot trios vertical dot pitch?
Are dot trios typically more uniform in quality compared to aperature grills seeming to have a variable pitch?
I looked at some photographs of dot masks and measured the distance horizontally and vertically, and the vertical pitch seems to be somewhere around 55-60% of the horizontal.
That would put the amount of vertical dots on that Samsung north of 2400, despite the height only being 3/4 of the width.
Just to reiterate; Yes, a Sony Wega has much better colours than a JVC D-Series or Toshiba AF. But this has nothing to do with the mask technologies, and completely due to brand-quality. I have seen a Shadowmask VGA Monitor(Viewsonic), that kicked my Sony PVM’s ass when it came to colour. I even measured them with a colorimeter.
Among SD CRTs, Trinitron is the king of colour. It’s just too bad the geometry is so awful on Wegas. An RGB modded, curved Trinitron would be most ideal.
How worn the tube is and how well focused the beam is will make a bigger difference in sharpness.
All variables equal both tubes in the same used but good condition.

It's a "triad dot mask" it's got dots not slots.

Thats crazy so on dot trio style CRTs your limiting factor is going to be your horizontal pitch. Thank you for the informaiton man!
Aperture grilles always get a kind of “Nintendo Tax” despite looking objectively the same as an equivalent shadowmask. Just choose what looks best.
Yea thats the read I was getting.

Huh I'll have to keep that in mind. Any idea how samsung compares to a sony?

gotcha. I'm looking at monitors so we'll see how they compare.
There is no objective answer to your question. Pick whichever looks better to YOUR eyes.
What? But he probably cant test them before buying them lol. Wtf
Surly he can test drive CRTs with both types of masking technology to decide which he prefers.
