Is the difference visible in vga mode (since | most of my software only has drivers for vga and I don't use | windows, I care most about what I see in vga mode)? The answer is "maybe." The important thing is the number of dots and the viewing distance. On the same size screen a coarse dot pitch may look less sharp. However, consider the NEC 3D and 4D. The 3D has finer dor pitch, but also a smaller screen. Therefore the number of dots is about the same, and at the same number of pixels, viewed from an appropriate distance, they look about the same. All things being equal I would rather have fine pitch, but it does not always mean that you will get a fuzzy picture. If you string 1024 pixels along eight inches, you have ~5 pixels/mm, or 0.20 "pixel pitch." If you think you lose resolution on both .31 and .28 dot pitch you are dead right. Until you go to something like a 5D, which is 20 inches, or a bit over 12 wide, you are going to lose at the high res display modes. Remember that sharp looking workstation display, like a Sun, is 72 dpi, or about .35mm dot pitch. I didn't give you an answer, but hopefully you can come up with your own now. -- bill davidsen - davidsen@sixhub.uucp (uunet!crdgw1!sixhub!davidsen) sysop *IX BBS and Public Access UNIX moderator of comp.binaries.ibm.pc and 80386 mailing list "Stupidity, like virtue, is its own reward" -me
