[comp.sys.ibm.pc.hardware] NEC 3D OK in interlaced 1024 x 768 ??

jc58+@andrew.cmu.edu (Johnny J. Chin) (09/27/90)

If my memory serves me correct, the new Nec 3D supports 1024x768 in interlace
mode (this is the only way to get 1024x768, that I've ever heard of).

As for the video card ... there are a few which supports 1024x768.
There is the Paradise VGA 1024 (I recommend this one)
         the ATI VGA 1024 (or something like that)
      or the Orchid Prodesigner II.

You will definitely need 1MB of memory to run the video card in 1024x768.
There is no other way of doing it.  However, you have one alternative.
Buy the 512KB version of the card and add your own memory (usually, they are
41000-80 chips, 8 or 9 of them depending on the card).

I hope this information helps.

Wellllll...not exactly.

If by 'the only way...' you mean the only way to get 1024x768 on the NEC 3D
is in interlaced mode, you're right.  It is possible, of course, to buy
a monitor capable of non-interlaced 1024x768 resolution.

Also, you don't absolutely need 1 MB of RAM for 1024x768 resolution.  
Consider that if each pixel takes up an entire byte (256 colors/pixel), then
you need 768 KB of RAM.  However, if the card is able to run where
you only use 4 bits/pixel (16 colors) then all you need is 768/2 = 384 Kbytes
of RAM.  Many cards are configured this way.

As for a video card, I still think the best buy going is the Genoa 6400
from Genoa systems.  This card can do every video mode known to the PC
world, from CGA to SVGA to 1024x768, including Hercules!  It scored a
perfect 100% on PC-Labs compatibility test.  It does 800x600x256 as
well as 1024x768x16, and can do 1024x768 in interlaced mode *or* non-
interlaced mode, so you can choose a monitor to fit your budget, and
upgrade later if you want.

Now comes the punch line: the card is available mail-order with 1 MB RAM
for only $200.  I know; I bought one.
