I have looked at these off and on and just wanted to make sure that I am getting the correct item. If I want to hook up my test bench to an LCD monitor, I would want a CGA to VGA converter like this?

If I want to hook up a PC to my arcade monitor, I would want this?

Any other info I might be missing to getting these working in both instances?

sounds like you got it, the vga to cga (bottom item) is junk, i couldnt get it to save settings and it would not focus correctly
 
I have both of those boards and I can say they do work great.

The CGA (EGA) to VGA I have in my APB and it looks perfect.

The VGA to CGA is installed in my MAME cabinet and looks just like a regular arcade cabinet.

If someone says these boards are junk, they might have got a non functioning board because they are chinese made.

From the Orignal Post.
"I would want a CGA to VGA converter like this?"

The bottom link is VGA to CGA converter. Great if you want a build a Mame machine. Not so good if you want to Build " I want to hook up my test bench to an LCD monitor"

The top link is to the CGA or EGA to VGA. I have two (thanks paradise arcade).
 
The CGA to VGA works on CGA or EGA arcade boards.

I have tested them on APB, Tetris, Arknoid, Championship Sprint, Pole Position...

I have tested them on a 21" Sony CRT, 19" Dell CRT, 19" Sony LCD...

All working fine
 
For my VGA to CGA needs from a PC, I always use the ArcadeVGA card. A bit of a pain in the ass to get it all set up but once it is, man, great quality! If you put a real arcade pcb on a monitor then the same game in mame on the same monitor from a computer with ArcadeVGA, you really can't tell the difference. IMO, the chinese converter boards introduce too much noise in the pic quality and drives it down. This goes for the CGA to VGA conversion as well *puke*

Good luck!
 
The person want to test his Arcade games with an LCD monitor.
I know these boards In the past had issues.
I bought these board withnin the last month.
I know they are sensative to crappy noise voltages.

A nice Old NEC mutlisync CRT would work :)
 
I have the top one. Works good in my jamma game, but doesn't seem to work in the williams games. Maybe a positive/negative sync issue? Couldn't find anything in the menu to change between the two.

IMHO, having one of these adapters and an LCD as a bench monitor isn't too useful. You will always be wondering "Maybe this adapter doesn't like the board's signal, that's why I'm not getting a picture" or chasing your tail with a sync problem that turns out to be the adapter when working on a game board. For a bench monitor you need something that is reliable, predictable, and known to work with everything. A real monitor will display a wildly out of sync picture - or at least some of it, allowing you to trace what's going on. Most LCD's just go blank. Personally, I have an old Apple RGB monitor on the bench that I'm using, but the NEC Multisync 3d is another good one.

I'd suggest using either one of the aforementioned old computer monitors, or a small arcade monitor.

How did you get it working on a Pole Position? I have two different models and neither one would sync properly on my PPII. I tried four LCDs and two CRTs and they all displayed the same sync issue. Game would be playable but the image would be jittery and the top inch would be more jittery. This is a boardset that works fine on a decent 4600.
