GroovyMAME 0.206 not displaying (black screen)

[Mr. Smoke]

Hello.  I'm having trouble running the most recent version of GroovyMame (0.206).  When I load mame64.exe, it does start but with no display (a black screen).  I have not experienced this issue in older versions (ex: 0.205 works fine).  I've compared the mame.ini files in both the 0.205 and 0.206, and the "Core Switchres Options" are the same in each file.  I'm not sure what I should be doing.  I'm running the "groovymame64_0206.017n_win-7-8-10" version of the software on a Windows 8.1 PC.  Any help is appreciated.  Thank you!

*** UPDATE: I have attached the log as a text file instead of pasting to the bottom of the e-mail.  Didn't see the "Reporting Problems" instructions at first, sorry!

*** Second Update: I was able to solve this issue by changing the "monitor" line in "Core Switchres Options" from "generic_15" to "lcd".  Weirdly, GroovyMame 0.205 will load/display no trouble with "generic_15", but this does not work in 0.206.

Hi Mr. Smoke,

I had missed your updates. You don't specify which type of monitor you have. GM's default configuration is for 15 kHz, and you don't have any 15 kHz modes installed, so it's normal that it doesn't work.

In that situation, using "monitor lcd" just defaults to the desktop's resolution, whatever it is, that's why it works, but I'm not sure if that's what you want.

Hi Calamity,

My mistake for not adding the log as an attachment in the first place.  I'm currently using an Acer AL1706 LCD monitor, but my ultimate goal is to connect my MAME PC to a New Astro City cabinet using JPAC once I get everything working.  That cabinet has an Nanao MS9 monitor. I was initially confused as I was able to run GM 0.205 with "generic_15" in the .ini file, but this did not work in GM 0.206.  I am able to run it now on the Acer monitor with "monitor lcd" set in the .ini file. 

Looking at the "Monitor Presets" thread, I see the following for a MS9.  This is what I should be adding to the .ini file before I connect my PC, right?

Thank you for your help, and for creating/maintaining this program.
