[comp.sys.ibm.pc] Interlaced Monitors v. Interlaced VGA Cards

rogerson@PEDEV.Columbia.NCR.COM (Dale Rogerson) (08/02/89)

I am a little confused over interlacing.  What controls if the display
is interlaced or non-interlaced: the monitor or the card.  
The Video 7 VRAM card will display 1024x768 NON-interlaced.  The VGA
Wonder displays 1024x768 interlaced.  The IBM 8514/a displays the
1k mode interlaced.  Is the following chart correct?

	VGA Board		Monitor			Picture
	---------		-------			-------
	interlaced		interlaced		interlaced
	interlaced		non-interlaced		interlaced
	non-interlaced		non-interlaced		non-interlaced
	non-interlaced		interlace		interlaced(??)

The reason I am asking this is because the Multisync 3D monitor is
much cheaper than just about any other monitor that will display
1024x768, but it is interlaced.  Also, Video 7 is introducing a new
version of the Fastwrite that will display 1024x768x16 Interlaced (according
to the latest issue of Byte Magazine).

Danke Sehr!
