Hello boys,

excuse my bad English. are Italian.

I have a problem viewing. :smt009

the image wavers on the vertical axis (up and down) with games naomi 2 (tested virtua striker 3 EU and street fighter 3 JAP all gd-rom) ...

But if I press the button TEST all menus, and testing grid monitors are perfect. not fluctuate. when I exit from Test, returns the defect. :smt009

my monitor is a 15k and 25k.

the naomi is set to 15k

Experts help you.

thank you :smt006

How are you connecting the Naomi to the 15khz monitor? Can you post a picture of the monitor defect in action? Sounds like you are not sending combined sync to the monitor input.

Try turning the V-Hold pot under the control Panel.

Think it's the 2nd from the Right (1 in from the volume)

hello..... thanks :smt006

yes.... 15k monitor and naomi...

I tried photos or videos, but do not see the defect.

I say this:

example, where there are bars energy street fighter, the white horizontal lines that form the rectangles .. vibrate up and down to 1mm

or:

the logo's title game, vibrate up and down to about 1mm.

if I make naomi testing ... the menu is perfect, not vibrate.

also test grid is perfect, not vibrate.

Then when I exit from the menu test, which falls within the system or naomi in the game, here is that vibrates again.

all games jamma or mvs (neogeo) are perfect, not vibrate.

this means that the monitors 15k works well.

also naomi, testing has the smooth video.

only vibrates in the game.

I did an example, taking a picture from the Internet ....

lines, which should be firm .. as well as the texts and words. vibrate / fluctuate, in the sense of red arrows.

so I explained? thanks to all

even the titles during the presentation, type capcom or warning. texts vibrate up and down, by about 1 mm. damage and nuisance.

Under the control panel, there will be a set on knobs for the monitor. One of these controls the Vertical hold (basically fine tuning of the vertical frequency)

If you turn this, the picture will roll up& down. Adjust this slowly until you get a stable picture.

Hello friend,

I tried that ... vertical frequency? right? but does not solve the problem. :smt009

i am sure this is just down to the way the naomi interlaces to 15khz,the game is meant to be 31khz.

your monitor is probably not as good as a nanao or sanwa at handling the naomi 15khz signal-i do not think there is anything you can do
