Hortizontal and Vertical monitors, same aspect ratio?

Hello all-
I am looking to get a new monitor for my Ms Pacman machine, which as I'm sure you know, has a vertical monitor. I've found a local guy in town that has a 19" monitor available with no burn in. The only hitch is that this monitor came out of an arcade where the screen was horizontal. Do you think that this monitor would still work in my machine? Seems like it would be the same aspect ratio, it would just be turned on its side, right?
 
Im interested to find this out too!! I have an extra monitor coming and its a horizontal monitor and would really like to put it in my nonworking Bump n Jump that has a vertical setup
 
There is nothing electronically that would prevent you from installing it. Arcade CRTs are 1.33:1 (aka 4:3), and just rotated to stand horizontal or vertical depending on application.

As Krajkerjac says, the frame is the only thing you need to worry about. Generally vertical mount has flanges on the short sides of the tube, while horizontal mount has them on the long sides — so the flanges point up and down when the monitor is installed. As always, there are some exceptions, but this is a good general rule.
 
am i crazy? i've never seen a specifically VERTICAL chassis frame. i've switched monitors between vertical and horizontal games lots of times and the chassis frame was never an issue...

Some vertical MCR games (Spy Hunter, etc.) use a vertical frame.

They exist. I have one. G07 if I'm not mistaken.
 
I was told that my Ms Pacman (the screen that I'm replacing) probably uses a G07. So does that mean I might run into problems after all?
 
The monitors shipped with different frames depending on the application. Look at the very first page of the G07 manual. The only difference is the metal frame, just swap it into another if its not the right one.
 
They are the same, and you actually want a horizontal-frame monitor to mount in your ms pac

Tron as well, mine at least

Qbert and sinistar are the only two i havewith vertical-frames, but even so electrical/signal compatible

Oops, I was wrong about Tron, but Spy Hunter definitely has a vertical frame.
 
Ok, so here is my monitor. Some people have said that Ms Pacman machines used G07 monitors, but I think I might have heard them say that was one of the monitors they used, not the only one. Unless I am missing something, I don't think mine is a G07. Here is a picture of a few markings on the monitor. Pretty sure the "CRT TYPE 19VLTP22" is just referring to the tube. Looks like the overall monitor is a Wells Gardner 19K4906.


Here is a front view of my monitor. Man! Once you have it from under all that glass and everything it makes the screen burn in look SO much worse! If I'm following you all correctly, once I get the new screen, I need to put it inside of that frame thats all along the outside. So really, to remove the tube, I mostly just have to remove the four circled bolts in the picture below.


So then I assume I need to also remove this chassis board from the back of the frame as well? Or would I reuse this and just hook up the new tube/monitor to it? If I have to use the board from the new monitor, do those come in a standard size where they would screw onto this platform, to the two circled screws below?


Looks like theres three connections I had to unplug to get the monitor out of the cabinet. If I have to replace the entire board with a new one, is that a standard thing, where those same three connection pieces will be on the new board as well?


Sorry so many questions, I've never replaced a monitor before!
 
A "complete monitor" includes the tube, chassis (pcbs), and the sheet metal frame with angled sides...

All you need from that if you're putting in another monitor is those two long rails, thats a mspac/midway part not a standard part of the monitor

If you plan to disconnect your monitor chassis from tube or frame, make sure you read up on discharging the monitor first, you dont want to get shocked

G07 and wg4900 are both common from that era...

Is that still the case if the monitor I am getting came out of a horizontal screen cabinet? I thought that complicated things?

I did discharge the monitor already, so I'm good there. And I think I have the possibility of getting a "complete" monitor if I want it, provided it all plays nice with everything. Like those connectors on the chassis, are those standard?
 
You can put a new tube on that chassis (if you can find one from a wg4900, but anything else is beyond normal (look up tube swap))

Or you can put your working chassis onto a broken wg4900 with a good tube...

EDIT: or you can drop in a complete different monitor, ie a g07, without interchanging parts

The horiz/vertical issue was answered, ms pac has a horizontal-frame mounted sideways... to see a vertical-framed monitor click q*bert in my sig


Lastly, no those two screws are not how you remove the chassis, the single screw below them (parallel to the yoke)

Small correction, the two smaller rails on the long edges of the monitor are also midway specific parts to hold the tinted bezel, so you might need to transfer that to your new monitor too

And as for your connections, they are standard as far as power/signal but the actual molex connector for power might be different and need attention... And the two signal connectors are spaced differently wg vs electrohome or others, but you'll figure it out, just look up the pinout

Ok, so I think that answers lost of my questions. Just one left. Are you saying that if this other horizontal 19 inch monitor is not a G07 or WG4900 then it won't work? If its some other model will it have those same three connectors?
 
Short answer, it probably will...

That is if its low res, color, raster, not sanyo/nintendo
Most are...

My advice, don't waste your time with a matsushita (sp?)
