crt+groovy+ arcade monitor +sync issue

[retroboy]

Hi everyone, I have previously setup a few systems running groovy without any issues.

I am having issues with a new setup, particularly trying to figure out if it is a vsync tuning issue or a setting issue (or even an 1d-10t error)

The graphics card is R7 240 which was my first question, should i be using crimson or adrelin? as r7 is listed in both.

im using 15k generic and have almost got the right picture but cant get it quite right, I've played with the monitor settings (probably made things worse) and now cant tell if its a software or monitor setting that i dont have right.

getting some flickering (color is ok) and image jumps. I have tried to check every post that seemed relative, have read multiple guides but am still pulling my hair out. If anyone could provide some insight of things to check that would be appreciated.
