Really nice monitor but can’t get any more width than this, tried hoz pots but doesn’t want to move any more. Any suggestions would be welcome thanks.

NON EXPERT WHILE WAITING ON EXPERTS:
I know ms9 chassis allows a width control on chassis (not the remote board one)
Maybe something similar

MUCH less knowledgable still, while waiting on experts, but I just got my first cab and had the opposite problem. Picture was too wide no matter what I did.

Turns out that there was a ‘narrow’/‘wide’ jumper on the chassis. Just needed to move the wire over.

Maybe that?ChrisBEANS2021-04-27 22:40:39

Sometimes there is a horizontal width coil that can be used to adjust the width, usually looks like wire coiled around a plastic tube, sometimes has a knob to turn other times you need a plastic adjustment tool to stick it to turn.

If you need to adjust the horizontal width coil, and it needs a tool, make sure you don't take a short cut and use a screwdriver...

Speaking from painful experience, the ferrite core is very fragile and can easily be damaged.iamjimmi2021-04-28 08:04:21

This.

And a metal Allen key gets very hot very quickly.

If you really can’t get access to the tool, you can wind it a bit with the game off, turn on, rinse and repeat.

Do let the monitor warm up before adjusting though so you get a good strong picture beforehand.

if the horizontal width coil doesn't cut it, there is also a cap in this circuit which you can replace with a higher or lower value to change the width. It's usually a chicklet cap near the coil.

Monitors differ, tell us the model :)

You shouldn't need to adjust the horizontal width coil, and even if you do (with a correct sized plastic allen key), it will probably just break anyway.

Depending on the monitor there's also sometimes a "shift" jumper to adjust the picture position.

It could be the result of so many things.

Cheers guys the monitor is a tatung type 58 vga monitor vt-2040B, the width coil looks like a cap and haven’t changed it and there is no way in adjusting it, I’ve played about with the different horizontal pots the frequency, phase and width pot doesn’t change anything. I changed the width cap by the flyback from a 680nf 250v to a 560nf 250v cap and it made it a tad wider but a matter of mm.

Like iamjimi said width coil.. it is the copper coil on chassi

Width coil but you want the plastic tv adjustment tool
As there is a fragile core inside the copper coil that a metal screw driver will break it.
If I remember right it is a flat type slotty I when attempting to turn it slowly and carefully.
Also and first try the width pot on chassi as width coil “should” be factory set in middle

Is your street fighter original or bootleg ?as that can through up image anomaly’s

Have you tired adjusting settings on the Gonbes to increase the picture width?

Also not sure about xbox360 with VGA as never had one setup before but is there anyway to adjust overscan settings on the xbox when configured for VGA output.

EDIT: Is this the same chassis as yours? I think the red arrow Ive added to this picture is the horizontal width coil if its on your board. Its a bit hard to tell with the zoomed in pictures you have posted instead of a full one of the chassis.
