Hate to correct you, but none of the CRT's have a native resolution. That's digitals that do. CRT's have a max resolving power before the lines overlap. So they have a max sweet spot but can scan all sorts of resolutions up to their max resolving power before you get line overlap or run into video chain limitations. |
Slip up from when I ran a digital projector my bad I meant to say max resolution(it happens when you work with both types of projector tech)

I think people need to do some more research into what lines of resolution really means. Let me throw another word in this mix, shadow mask.

Applicable on direct view sets only.

I think people need to read and think about what question the OP was asking. Let me throw another word into this mix: Irrelevant.

I'm running my lovely barco 808s.
So, all I need to do is convert the lines to DPI and the faq will be done (Curt, can I upload it to the faq section when complete?).
That said, I' going to have to sample all the provided VGA settings and see which ones work best for my computer.
I can deal with that, as it's a one - off process. |
Hmmm… I'm not sure I understand where you're going with all this, Shelley. The term "DPI" (dots per inch) usually refers to the spatial resolution of a digital image, but it's a function of size. It's rather inexact with projectors, since everybody's screen is different, there's overscan, and of course you can have scaling (with an input AND an output resolution), etc.
Tell us a little more about what you're trying to accomplish, and maybe we can help fill the blanks a little better for you.
Cheers,
SC

Sigh. OK, Mac. Please explain how the shadow mask on a direct-view set has any relevance to the lines of resolution (in essence bandwidth) of a source format like VHS, Laserdisc, or cable TV. Of course, the shadow mask and dot size can impact displayed resolution, but we're not talking about displays; we're talking about source formats. Further, as someone pointed out, a shadow mask has no relevance with projection, either. So, please do indulge us with why you even brought it up.

Nah, there is way more then enough info out there on the net for anyone who wants to learn what lines of resolution really means. The shadow mask word was only thrown in as a hint to understanding the phrase which was used mostly in times when displays without a shadow mask were almost non existent. It does not apply directly although is highly dependent of use for such display type.

Agreed, though much of that info "out there on the net" is either highly technical and therefore of questionable utility for somebody like Shelley, or is so dumbed down as to be pretty useless. I'm sure there are some good resources, but finding them, and trusting them, are a whole other thing. Personally, I know exactly what 'lines of resolution' really means when applied to source and transmission technologies, so I explained it in laymen's terms, which I think was what the OP was after.
While the 'lines of resolution' term was in use during the time when direct view sets had some sort of shadow mask, again - the two aren't directly relevant. Similar to 'source' and 'display' resolution now, the 'lines of resolution' specification on source and transmission technology was irrespective of display technology. Besides, my dad had a front projector for about half of my childhood. No shadow mask, there! Again, other than muddying the waters, I still don't see the point in bringing up a display term in this context.
And, I'm just curious, here… But, why "throw in hints", Mac? To me, that's almost as bad as posting snarky "ltmgtfy" posts. Maybe it's worse, because at least the ltmgtfy posts will actually direct the user somewhere instead of just leaving them to guess about what you mean. I understand the subject matter, and I still don't see understand the relevance. To me, either post the information you think might move the thread forward and help the original poster, or don't.
Just sayin'.
