I am currently using the display enhancer with a "Super-VGA" monitor (you know the 800x600 non-interlaced, and 1024x768 interlaced ones), with no problems. The only thing I don't like is the fact that my monitor doesn't have a horizontal width adjustment so I have about 1/2" of black nothingness on either side of the image. Of course to compensate for this I put my workbench screen into 700pixel wide overscan and it looks really pretty. The only problem you will encounter is if you try to use the ECS "Super-hires" mode (1280x200/400). The card doen't sample the pixels fast enough to get 1280 on one scan line, so it will only sample every second on (giving you the 640-wide resolution). The manual says to put the card into bypass mode for this, which of course the VGA monitor cannot handle. Another small complaint I have about the card is that it makes lo-res look really crappy. You can see each pixel with perfect clarity (no scanlines and cheaply made monitor to hide it). I really cannot stand to look at a non-interlaced workbench screen anymore (WB 2.0 looks pretty lousy in non-interlace anyway :^) ). The only trouble you may have with a VGA (not Super-VGA) monitor is if you switch to PAL (w/ [Super | Fatter | Obese | Fatter | Pregnant | Huge | really-neat-now-I-have-a-whole-meg-of-chip-RAM] Agnus), it may not work. I'm not sure about this but I think the frequency is a little different for PAL, and a standard VGA monitor may not like this (Super-VGA monitors will adjust within a limited range... mine goes from 28-33KHz I think). - Alun Fryer "And now for something completely different...

Actually all modes look worse to me. Now that I can see every pixel, they don't all blend together like they did before - but what I'm seeing IS CLEARER! So what-the-hay, it just makes me more critial of the pix I do from DigiView... ;-) -- Guy Dandrea, Network Systems Corp. // guy@nsco.network.com #129.191.1.1 \\ // 7600 Boone Ave No, Mpls.

There's a program available called "setlace" which puts those lo-res screens into interlace by displaying each scanline twice to fill in the gaps. Those lo-res screens end up looking much sharper! -Norm > - Alun Fryer > -- // Norman Heu \X/ nheu@heuvax.wimsey.bc.ca -or- uunet!heuvax.wimsey.bc.ca!nheu
