Title: VGAarcade on PC monitor?
Post by: lettuce on July 16, 2005, 06:17:48 pm

Is the VGAarcade card surpposed to work with a PC monitor aswell as an Arcade monitor? As im trying to setup my PC to go in my mame cabinet, but cant seem to get the VGAarcade card to display a picture on my PC monitor at all, just shows the no signal screen on the monitor?

Yes... does your AVGA card have two VGA type ports on it? One port outputs limited to 15/31.5Khz and the other port is std.

No its just like a normal gfx card, one socket for the monitor to plug into, and one for s-video

Ah they made that change when they went to the 9200 series. The 7000 series has two outputs.

You might have to look at your monitors minimum refresh rate. Some VGA monitors will not see a signal if it is below 31Khz.

Surely it would display a picture for the dos screen at start up? I guess ill have to wait till i connect it up to my arcade monitor to find out if its working or not

Sadly the "dos" screen at startup (such as the BIOS) is not in fact 15KHz signal. Its actually over 31Khz.... This is why its viewable on normal PC monitors. I think most VGA cards "doublescan" these frequencies (ie draw every line twice) so they can be displayed.

If the ArcadeVGA is outputting 15Khz signals, then you won't see it on a normal Pc Monitor.

Ah, ok, i did notice in the BIOS est up u can change the screen, form VGA, to different forms of CGA settings, would this make a difference?

If you have the model with one VGA connector, then you can ONLY connect it to an ARCADE MONITOR.

Here's the instructions for the new ArcadeVGA card.

Incidentally, the performance with a PC monitor (the old AVGA) is poor due to the fact it is only intended for setting up / maintenance.  ie you should not use an ArcadeVGA with PC monitor for gaming.

Just put a different (normal) graphics card in while you set the pc up, and switch back when you go to an arcade monitor.
