has anyone here used old crt pc monitors for tube swaps? i was thinking of checking my old crt's to see if i could swap one for my GO7
 
I haven't tried, but I keep meaning to, just to see what would happen. The big problem with computer monitor picture tubes is that they're the wrong size. A 19" TV tube is a different size than a 19" computer tube - the TV tube is bigger. That's because TV sets are sold based on viewable area, and computer monitors based on the size of the glass envelope. That's why a 17" computer monitor only measures like 15.5" diagonally.

Other than that, if the neck pinout is the same, you should be able to get a picture - but I don't know if you'd be able to converge it or set purity. Computer monitors tend to use more complicated yokes, especially for the monitors that allow convergence tweaking from the front panel. I'm not sure you'd be able to get the arcade yoke in the proper position to get a usable picture.

Another thing is that computer tubes have a much finer dot pitch than a TV or arcade monitor. If you did get a picture, it might look a bit... fake. It's definitely going to look different than a standard tube.

I still want to try it, just to see what would happen. But it's not going to be a direct drop-in replacement like a TV tube.

ah ok well that answers that
 
Unless.....unless.....you want it to be a vector :)

I'd love to try a hi-res tube on a SW cab. The problem is finding a 27" computer monitor.....

Even a 19" 6100 with a hi res tube would be fun to see. Hmmm...

Yes....I wonder which way it will go....either the lines are too thin or it will have the sharpest vectors ever (I think then you would reach the point where color vectors will look a lot like the old B/W (minus the phosphor lagging of course....)
