I have a problem using this mode in that the text is distorted and looks kinda 'fuzzy'. The display is very sharp at all other resolutions. I realise the display is interlaced in this mode but I have seen the monitor used with a Tseng labs card and this mode looked much better. The exact model of the card is TVGA8900b E6-100C Ver 1.41 It has 1Mb of memory installed. This problem is not common to windows. Please help as I hate running windows at 800x600. s870694@minyos.xx.rmit.oz.au

Tell me about it. I have a 8900 as well, with a ctx 1024x768 trisync. It too is interlaced in this mode, and it is pretty fuzzy. Actually, looking at it closely it seems that alternate sweeps don't really get offset at all. This is not due to the monitor, as i've tried this card on a NEC 3d (beauty monitor) and the same thing happens. Also, my friend's Swan Tseng4000 looks perfect in interlaced 1024x768 on the 3d, and almost as good on the CTX. Also, the 8900 is almost a half an order of magnitude slower in most screen writes :(using vid- speed). An inferior card? Maybe. Hell, BIOS writes on his card are almost faster than direct writes on mine. ARG! Then again, I think my card is showing signs of problems - the 800x600 mode occasionally has trouble synching. Also, it doesn't always seem to clear out the screen memory when i crank up windows - the bottom 1 1/2 has random junk left over from earlier sessions and/or fractint screens. Wierd. Anybody else see this, or is my card brain dead? Incidentally, i'm using the tvgawin2b beta versions. Still haven't heard anything about an official release... nye

I'm using TVGA 8900 E6-100a 1mb, connected to a PanaSync (multi-sync) C1381. Mine looks ok in all modes -- from the lowest resolution to the highest at 1024x768x256. I'm using the original drivers but I've also tried the new 2beta (from cica) for 256 colors but didn't like the color bugs(??) So, I'm back to the original 800x600x16 driver. But as for 1024x768 in both 16 & 256 colors, I don't believe I have any problems that you guys mentioned. My only complain here is the words and icons are too tiny -- tuff to read :-) The 2beta driver with the larger sys-font doesn't look too good, (eg. some text exceeds the little window/ space alloted by the program, eg. in TimeLine and K-Free 2.2) >>Please help as I hate running windows at 800x600. >Tell me about it. > >I have a 8900 as well, with a ctx 1024x768 trisync.

Doesn't look perfectly- ultra-sharp, but after I windex the screen, it looks much better. Anyway, it's only .28 dp screen.

One things that you might want to try (if you haven't) - load the driver that will copy the 8900 ROM into RAM -- for faster execution. Add "device=tvgabio.sys" to your CONFIG.SYS file. (Chapter 4.4+ in the manual.) On a 16-bit machine (with the code in RAM), the increased speed will depend on your hardware limitations. It's fast enough on my 386/25 machine. > Hell, BIOS writes on his card >are almost faster than direct writes on mine. ARG!

Also, check the pin switches and jumpers to make sure that they are properly configured. (aaah! it's the DOS world :-)) And most important of all, check the current memory addressing scheme -- it's 64k by default, and you might need to switch it to 128k. (Use MAMODE.EXE from disk #1) Well, if all else fails, call Trident Microsystems in Sunnyvale (CA) at 408/738-3194 (See info at end of Appendix D (Troubleshooting) in the manual.)

I have a Swan SuperVGA card, 1 Meg, 1024x768x256, and the screen "rolls" in 386 enhanced mode, on a NEC 3-D monitor, it is fine in real mode. . . I remember reading an article in this group a few months back which had a suggestion to add a few variables to the WIN.INI file, anyone have any idea what these could have been? Later.
