Question about horizontal clocks Advance Mame

[AMDman13]

Ok so I'm a noob who wants to try Advance Mame on my Betson Imperial Kortek Multisync.

I'm not sure that I understand the clock settings in advcfg and unfortunately there is no automatic settings for the Betson.

Here is advance mame's example of a typical multisync.
device_video_clock 10 - 150 / 30.5 - 60 / 55 - 130

What is the breakdown here? I've checked my manual and I find anything as low as 10?
Here is what I figure my monitor is capable of 15.75 / 24.827 / 31.469 / 37.88
Each setting is for CGA, EGA, VGA, SVGA..

What the heck are the 10 - 150 or the 55 - 130?
Please help? Thanks...

Thanks for anyone who has read the thread..
It appears the 10-150 are the pixel clocks and the end of the string "55-130" are the vertical settings..

Now if I could only find out two things.... How to get the advcfg program to accept my custom string for betson multisync... Find out what the pixel clocks are for the Betson.. I'm planning on starting with 5-150.

If anyone can help that would be great!

Another update! i got it working tonight with custom settings. Simple really. Just a matter of typing all the strings in correctly. I was happy to finally see my old skool games at their native settings. I will say that the Betson stinks at 15.75  for side scrollers and this is why I will not be purchasing the arcadevga
