DVI-VGA Adapter

[stelleg151]

I was wondering if there is any negative effect to getting a dvi card with an adapter for a crt. Thanks

No worse than with any other VGA cable, in theory. All it does is connect the VGA output pins on the DVI-I out to the VGA inputs on the monitor.

Sweet, also, VGA means the standard 15 pin connector, right?

Yes; I am using the common (although technically incorrect) parlance of referring to a 15-pin D-SUB connection as a "VGA" connector, since they're used the vast majority of the time for carrying VGA spec video signals.

And -- perhaps more importanly -- what else would you use with a CRT?

vga is the incorrect way to describe the 15pin d-sub connector. vga stands for video graphics array and the protocol specifies 320*240 resolution (a bit obsolete yes). So its better to reffer to it as d-sub and not vga in order to avoid misleadings

VGA is 640x480 and QVGA is 320x240, no?

Regardless, "VGA" seems to have replaced D-sub in the vernacular.

vga is 320*240 and svga is 640*480. 800*600 and 1024*768 are xga. I might be wrong if my memory is not playing games on me though

I'm almost certain SVGA is 8x6 and XGA, 10x7. Then there's WXGA (12x7), SXGA (12x10), SXGA+ (14x10), UXGA (16x12), and some others I'm not sure of (19x12 = WUXGA?).

I think games are a distinct possibility.

damn those -GA's

Well, long time ago when I was playing games in dos (back in 94-95 or something) I do remember setting game's resolutions between 320 and 640. Games called those res. vga and svga. I really cant remember options from vesa dos driver though :/ Oh I miss my S3 Virge 3D2000 (paid about $150 for that baby )

What I really need to know is if a DVI-VGA adapter will work well at 1600x1200 to my crt.

That depends on the cards DAC's but for most recent cards even w/ a DVI to VGA adaptor you should not have any quality issues up to 1600x1200 over that and the adaptor may cause signal quality issues or so I've heard, I'm using one w/ my Compaq P110 on my BBA 9800Pro w/out issue tho. if that helps...
