Hantarex 28 polo star with Sega Naomi

[Bjt]

Hi. all

I need some help with Hantarex Polo 28 star. I get a good picture with the Naomi arcade system on 15 Khz but not on 31 Khz. Is the screen not compatible with 31Khz? mode? or do I need to change something in the monitor settings? Someone i know said that it is only compatible with Vga 15 khz? Does anyone know anything about these monitors?

If you have an answer for me that would be great before i demolished everything, Thanks B T

What kind of picture are you getting with 31khz? How is everything connected?

Star is an auto syncing chassis.

The 6-pin connector is for high impedance video, the VGA connector is for low impedance (75 ohm). There's a jumper that must be inserted if you use the VGA connector.

Hi,

At 31khz, you need to modify settings RV1, RV2, RV3, on the E/W module. (Marked in yellow color)
