If there is a way to run 24 bit at 1600×1200 I'm extremely interested. I missed the beginning of this thread and I apologize for jumping in but that resolution sounds great! What kind of Horizontal and Vertical synch does this card use? If it will synch on a 6FG then it should synch on the 5D also. The synch ranges are fairly close. We have 5D's and 6FG's but no Taxans. It would sure be nice to see that resolution though. Thanks For Any Info, Paul

Paul: The product mentioned was the Omnicomp Alamo, you can call them at (713)464-2990. No, the 5D won't do it. It peeters out at 1280×1024. You'll need a monitor which handles a 135 MHz bandwidth, 78 KHz horizontal scan rate, and 60 Hz vertical refresh rate. The 6FG meets the spec, and works (I've run mine at 1600×1200 with good results.) Evan

Evan: I found the original message in the thread. 3DS and Autocad drivers? Sounds fantastic! Are you running this board or is there another board that produces this resolution? Paul

Paul: No, the best I have is 1280×1024 at 24 bits. Evan

Evan- Are you sure you got the horizontal and vertical Hz right? Shouldn't it be 78vertical and 60horizontal. And were do you find the bandwith rating of the monitor. I have a viewsonic 7 and can't find the bandwidth rating in the documentation. Carl-

Carl: No, I'm pretty sure I got the frequency specs right – unless my fingers slip. 78 KHz Horizontal 60 Hz vertical. Generally, bandwidth is an obscure rating. The Viewsonic 7 should be nominally a 100 MHz monitor. It's good for 1280×1024 @ 60 Hz vertical, or 1024×768 @ 72 Hz vertical. (Going from memory) Evan

Evan- Maybe you can give me a little tech. info. here. I thought the horizontal ratings were usually lower than the vertical ratings. Ex: max on the Viewsonic 7, 64kHz horizontal, 90kHz vertical. Do or can some manufactors set which direction of scan is to be higher than what other manufactors set? Always trying to learn something- Carl

Evan- Is that interlaced at 1600×1200?

Peter, Matrox also has a board that does 1600x1200x24-bit. Kevin Krell – Computer Support Associates

No, it's non-interlaced. Evan
