I am putting the retropie OS into a chicago gaming company arcade legends machine. I have an hdmi to vga adapter since there isnt an hdmi in on the old tube monitor inside of the cabinet. When booting, the OS is split into 3 identical images on the same screen. I have tried to change resolution with no luck. Any help figuring out how to turn it into a normal image would be appreciated.
@lex_roar Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first
@BuZz fixed now i believe.

Is the image split vertically or horizontal?
As In ;
If it is option #1 there should be some adjustment knobs for the CRT television that adjusts the scan and should fix that.
We used to do that to my old TV back in the day . We would also experiment bringing magnets to the tube until we permanently screwed up the lower left corner.
I though it would be easier if I just showed you. Here is what the screen looks like, and here is inside of the arcade cabinet. These 5 knobs don't help me. Three of them are the RGB's, and the other two I was messing with and didn't do anything. Any other advice? (also note that the computer inside is not functioning, it needs to be there to power on the board that powers the CRT, I have the Pi outside of the machine currently)

So, this is where we reach the limit of what I might be able to do remotely. The picture looks to be the effect of Horizontal size setting needing adjustment. If there are no other pot adjustment knobs then you may have to look for jumpers to make adjustments.
With that said have you plugged in a more current monitor to see if the effect goes away? Just to make sure it is not some setting in the Pi that is causing it.
below is a clipping from a crt trouble shooting site.
"Horizontal size should be set so that there is about 10-15 percent overscan left and right. This will allow ample margin for power line voltage fluctuations, component aging, and the reduction in raster size that may occur with some VCR special effects (fast play) modes.
Many sets no longer have any horizontal size adjustments and depend on accurate regulation of the voltage to the horizontal output stage to control horizontal size. There may be a B+ adjustment to perform first.
On those that do, the adjustment may either be done by setting the B+ voltage, by a pot, or a width coil in series with the horizontal deflection coils.
Modern sets do not generally have any linearity control but you may find this on older models. You will need to go back and forth between size and linearity as these adjustments are usually not independent.
Some of the newest sets control all these parameters via settings in non-volatile memory and use service menus accessed via the remote control for nearly all setup adjustments."
