Those using a j-pac w/ arcade monitor

[kenzo42]

for those using a j-pac hooked up to an arcade monitor for MAME, was it too bright? via the amplifier boost?

btw, this will be used w/ an AVGA.

the dreamcast looks perfectly fine w/ no boost, via vga box.

othewise, i'd just get the i-pac. can the boost be turned off?

tia.

Well, I'm waiting on an ArcadeVGA as I'm typing this, but having used the J-PAC through a regular 9200SE the picture seemed to be fine and did not appear too bright or washed out.

I don't think it's gonna make your picture too bright as quite a few seem to use the J-PAC/ArcadeVGA combo with great results.  Definitely get the J-PAC instead.

I use mine with an ATI Rage, and it looks fine.  Can't comment on the AVGA.

I have the Arcade Vga and a Wells Gardner D9200. I havent hooked them up yet but I was wondering if it's neccessary to have a J-Pac? My monitor has a VGA cord.

The J-PAC's purpose is to directly connect to an existing JAMMA interface.

If its too bright--turn down the contrast/bright until you get an image you like--If your monitor doesn't have enough range you can adjust the "screen" pot on the flyback itself.

Menace,

have you noticed any difference between having your K7000 hooked via a video amp and no video amp?

I've used the video amp before, unless the monitor needs it..don't use it. Instead of hooking the video via the j-pac, couldn't you just splice the R,G,B, Ground and Sync from the jamma harness and connect those wires to a hacked VGA cable? I'm about 99.9% sure this will work. This is if the J-PAC won't allow you to turn off the signal boost. Also if you were splicing the wires, don't cut too close to the edge on of the harness. This is so you can reconnect them later if need be.

stellarolla: why don't you like the video amp?

i too would like to know how a monitor w/ mame looks w/ out a video amp. anyone? thanks.

When I had my videoamp and my arcade plugged up to my monitor the pictured looked extremely bright and faded. I had to go into display settings and change the color and brightness/contrast down and all over the place to get the right colors. Also when I tried to hook my dreamcast up to my monitor it faded to white. Once I finaly hacked a vga cable, and totally took out the video amp, I didnt have to mess with any of the colors settings on the PC display settings. Also the dreamcast didnt fade to white. The monitor didnt need it. I've treid this on a 19"inch Wells Gardner and a 25" inch K7000 series Wells Gardner. They both just didnt need the signal to be boosted. Some monitors, I've heard can look dim and would require a videoamp for correct picture results.

Here are some pics of the picture on my monitor WITHOUT the videoamp. All clean..


Pics of Street Fighter III: 3rd Strike (Dreamcast via vga box back at 15khz)

and of Metal Slug 2 (PC and arcadevga, NO VIDEOAMP!) Sorry the flash on the camera is on, but u can see how crisp the picture is.
