Mame doesn't display the Avres generated resolution

[ebo0763]

It's a little weird. It seems like mame does not choose the resolution in the .ini files. With Mortal Kombat and Final Fight for instance, the resolution his around half the width it's actually supposed to be. But when I manually choose the resolution in mame (instead of auto res) it's all good.

The thing is, I don't want to manually find the resolution for all games. What do you think could cause this?

Here's the ini file for mk3:

## mk3 ##

screen0 \\.\DISPLAY1
switchres 1
hwstretch 0
bezel 0
backdrop 0
resolution 401x256
resolution0 401x256@0


And how it looks like on my arcade monitor:



Those are my video settings:
