Default Blue, white, and HDMI cables for a 23-inch diagonal monitor

Does it matter in the "quality" of the end result which cable I buy?


With this amount of info to go on, I'd take HDMI, because "it works".

If you want additional feedback:

1) Provide the monitor make and model number. E.g. Acer MX123 or Asus 97GX
This allows reviewing the native resolution we're trying to hit
(which is likely 1920x1080). And perhaps the Internet has a picture
of the back of the item.

2) If you provide the information about the driving video card itself,
that allows heading off trouble. This is usually harder for posters
to dig up, unless they hold onto the video card box when they buy one.
The only reason in this case, that we care, is if the video card is
an AGP one, from when NVidia made their first cards with digital output,
there's a couple card models which only do 135MHz clock, when the spec
says they should work out to 165MHz. This might prevent such a card
from reaching 1920x1080 perhaps, and you might consider using a VGA
output in such an (obscure) case. My NVidia 7900GT for example, I don't
think I have any accurate identifiers on it, and Device Manager tells
you "7900GT/7900GTX", so it won't say specifically what it is. Then
I might attempt to use GPU-Z from Techspot.

The chances of you being screwed on (2) are slim to none.

If you have really old video cards, ancient ones from when dual
head first came out, the second connector on those might only
do 1024x768, but you're not likely to have something that
ancient on a Windows 7 computer. There could be corner cases.
We were able to buy ATI 7000 video cards for years and years,
so there was rubbish in the retail channel for a long long time
(i.e. unlikely to be able to still find specs for it).

But if you have HDMI at both ends in front of you, then
that is highly likely to be "the answer". To get the best
price, don't buy those locally. Unless you have a Frys maybe.
I could see you paying $25 for a $3 cable with some
"Monster" branding on it, and gold-tinted connectors.

*******

If you want to use 25 feet of HDMI cable, then you're going to
need a higher quality cable. It is possible to run some
distance, but you might not get it right on your first
purchase. The higher the resolution, the higher the clock
rate, and the harder it is to get decent signal amplitude
on a really long cable. You could likely send 1024x768 @ 60Hz over
HDMI a good long distance. Sending 4K at 144Hz via a modern
HDMI standard, less so.

HTH,
