How to get more visible scanlines? 240p? And error switchres could not find a?

(1/2) > >>

iguanastorm7:
Running MAME.  HDMI to VGA out of my laptop.  View Sonic 20G.  My question is how do I make the scanlines pop?  Is there a way display 240p in windows with an Nvidia GPU?

Also getting the error "switchres could not find a video mode that matches your specs".

iguanastorm7:
Looks like I just need to set the correct Monitor type.  I have a PC CRT.  Tried lcd on the ini and the error message went away however that created game slowdown.   There a list of monitor types for the Groovy Mame ini?

iguanastorm7:
Found the monitor presets and not sure which one I should use.    My CRT is 31khz and up is all I know. 

Now I have more problems.   See the pic attached.  See where the trees look split?  That's a line that sort of scans from the top of the screen to the bottom.  Some sort or refresh issue?

Also the music in all games started slowing down.  I fixed this by disabling autosync.  I read in an old post not to do this.  Have things changed since then?

Thank you in advance!

iguanastorm7:
Tried Groovy Mame on my other laptop and it's doing the same thing.  Runs very jerky.  Tried Stock Mame (not Groovy Mame) just for giggles and it runs fine.  So my laptops don't like Groovy Mame.  Suggestions  for fixing Groovy Mame on my laptops?  Do you need a log file?

iguanastorm7:
Log file is attached.   

This is on a Dell Core i7 Laptop with a fresh format and installation of Groovy Mame. Left all options default in the ini. 

Sure would appreciate some help.  Thanks!
