top of my imagine is smeared help

[hillbilly]

Hey all

i have an older WG 723229 19" standard res monitor, i had it in a mame cab before and now i bought a neo geo board and have it hooked up to that.
Now my problem is that the top inch or so of the monitor has the pic distorted like it is being smeared. only think i can think of is that when i had it hooked up with mame i had the R, G, B, Ground, -v, -h hooked up and my neo harness only has one sync labeled com sync. now what i did was wire it to the -v everything looks great except i cant get the top of the image to display correctly i will try to post a pic so you can see what i mean.
any help would be great

oh yes i have tried to adjust the pots on the back but it just wont work, and i have tried adjusting the voltage and this helps some but does not completely remove the problem

after using a bit of the search for sync on this site i found my problem. I guess i shoul have been using -hsync instead of -vsync. all i did was split the com sync to both -vsync and -hsync and my problems all went away
