Power Macintosh 8100/100 and a PC Monitor

Hi All,

I have a Power Macintosh 8100/100 here, and I have an IBM G40 PC Monitor attached on it by an adapter...

It's really working, but on a low 640x480 resolution screen... This monitor works on other PCs with full 800x600 or 1024x768 resolutions...

How can I change this on the 8100?

P.S.: On the screen icon on the dock only apears 640x480 67Hz...

Thank you all!

Use the Monitors control panel to change your resolution.

Your Mac to VGA adapter is probably locked at 640x480

Your Mac to VGA adapter, is probably set internally to work only at 640x480. Many were like this and were sold very inexpensively because of this. The only way to get a higher resolution will be to purchase an adapter that is configurable (via DIP switches or some other means). See: http://www.compusa.com/products/prod...0802&pfp=srch1 I have this and it works well. You can also find it elsewhere (check eBay) for less $$$.

If your 8100 has only internal (built-in video), you should consider going on EBay and finding an HPV (high performance video) PDS video card and also get 4mb total VRAM SIMMS to get 1024x768 at millions of colors (also using a configurable adapter, like the Belkin above). It just depends how much you want to spend on an this older system.

Here is some useful info from:
http://www.lowendmac.com/ppc/8100.shtml

8100 Video:
Internal (built-in video) supports thousands of colors at 640x480 and 256 colors at 832x642
2 MB PDS card and AV card support millions of colors at 640x480 and 832x624, thousands of colors at 1024x768 and 1152x870
4 MB PDS card supports millions of colors at 640x480, 832x624, , 1024x768, and 1152x870

Good luck, and if you have any other questions, I will be glad to try and help.
