9800 Pro - use crt or dvi/crt connector?

I am installing an ATI 9800 Pro today.
My monitor is a Sony 19" HMD A400 CRT.
Included with the 9800 Pro, is a dvi to crt connector.

What typically is the method of choice? Connect to the monitor from the crt
out on the card, or use the dvi out with the dvi-crt connector? Any big
difference?

Thanks,
 
Don't use the DVI connector. Just connect the monitor cable to the regular
VGA connector. That way you are getting analogue out of the card into the
analogue input on the monitor.

I tried it i ot NOTHING :)

Then again that DVI thing is just for LCD flatsreens right ?
 
Ok, thanks. Wasn't quite sure which would be the best as it included the dvi
to crt adaptor with it. I had already just used the regular cable to the vga
connector on the card. Very pleased so far.
 
The DVI connector is for LCD flatscreens, or any other kind of monitor that
requires digital input.

My HP CRT monitor has a DVI connector on the back of it as well as the
normal D-shape connector. Would there be any benefit in using the DVI
connector on my 9800 Pro to this monitor?

Probably not a major difference, but cutting out the anologue path is
usually a good move.
 
I believe that the DVI output is DVI-I, which means that it can be used
for EITHER an LCD monitor or (with the adapter) an analog VGA display
(in fact, that is the only reason for ATI to even include the adapter).

Basically, that port is for one of the two channels (1st or 2nd) of a
dual-monitor system, while the analog-only port is for the other
channel. I believe that it can be used for either analog (with the
adapter) or digital. If only one monitor is connected, it should
auto-detect whether it's the analog-only channel, or the DVI port
(either digital or analog). If two monitors are connected you will have
to use the control panel to tell it which is the primary monitor, also
you will probably have to install "Hydravision".
 
That statement is not generally true. Most DVI ports on video cards are
DVI-I ports. That means that they support BOTH an analog display (with
a connector adapter) and a digital display. A DVI-I port has both the
digital signals and the analog signals present at the DVI connector. To
use the analog signals, you only need a connector adapter, or, in some
cases, a "splitter cable" (to use BOTH the analog and digital signals of
the DVI port simultaneously). The only reason for a vendor (ATI) to
supply a DVI to VGA connector adapter is to allow use of the analog part
of the DVI port. The DVI spec is non-specific as to whether the analog
port is the "same" video as the digital signal, or whether the analog
port is an entirely separate channel (e.g. for a dual-display
configuration).

Note that quite a few ATI boards, especially "All-in-Wonder" boards,
have ONLY a DVI connector, and that an adapter must be used to connect
an analog VGA monitor. Clearly, in such cases, the DVI connector is not
for LCD flatscreens only (or even for monitors that require digital
input), as not only do most CRTs not have digital input, but, in fact,
most LCDs are actually analog rather than digital.
 
The only difference between the connectors is that VGA is analogue and DVI
is digital. If your CRT monitor has both connectors then it is an analogue
monitor with circuitry to handle digital input which is then converted to
analogue. Just go with analogue and bypass the digital conversion
circuitry.
