Buzzing Monitor and Squished image WG9200

I'm getting a weird buzzing noise on my 9200 WG monitor. It doesn't do it on my 1 slot neo geo board but it does on my Atomiswave and naomi boards. Here's the video of the problem maybe someone can help me. I want to sell this cabinet and I want to make sure everything works perfectly.

I guess the difference is in the fact that your Naomi and Atomiswave are probably both running at 31khz. MVS is 15khz. Can your chassis handle both automatically, or is there a manual switch that you need to do? Or did it just work fine in the past?

if you are running the naomi at 31khz then use the vga connection

looking at the wg website it shows the frequency as manual select via the input plug

otherwise if the naomi is running at 15khz and not syncing it could be down to the fact its interlaced and slightly out of range for the d9200

I have the naomi and Atomiswave on 15khz. It works fine on 31khz, but it's a pain to change it from 31 to 15khz when you have the monitor cover on

i think it really is a case of that the d9200 cannot sync to interlaced 15khz-you should ask wells gardner direct
