Tri-sync with no signal when starting groovymame.

[wildpumpk1n]

Hello guys,

I've got a New net City with a tri-sync chassis.
My monitor is a matsushita with a PD1843

I've tested the chassis with a Naomi system in 15khz and 31khz
It works.

So I made a build with crt emudriver, an R7 240 and few system using groovymame and retroarch.
I used a jammAsd to block 31khz resolution.
So when I start a game with groovymame, my monitor put a no signal (like a change or nothing to show) and the screen comeback with the game start.
I quit the game, again, no signal and going back to gm or Hyperspin.

I made a log of it can helps.
Thanks In advance if you've got any way or idea .

So, to clarify, in-game picture is correct, right?

[wildpumpk1n]

Yes, I can check it, it's wrote with the super res resolution.
I will make few pictures tomorrow and a video.

So i made few videos.
As its fast and the light was not perfect, we cant see the "no Signal" at start in the video. We can see it at the end really fast in the 39sec

Edit : I think this part is not from the same trouble
I retest with gm 0.228, gm 0.225, there are line
I test with gm 0.214 no line. Is there big change between these revision of gm?


I made few others videos with a line we can see in twice place on the screen.
With a horizontal movement like for Beat em up we cant see it but in a vertical movement like with the shmups its clearly visible.

Watch on the right, the island/tree and on the left, you will see the line
