Default HDMI or Displayport?

I'm going to be adding an outboard graphics card to my PC. It has, one
each, a DVI-D, a displayport, and and HDMI port. My two monitors both have
DVI-D ports. I know I will need to get an adapter cable of some sort to
connect the second DVI-D monitor to either one of the other ports. Which
one would be best the displayport or the HDMI?
FYI, my second monitor also has a VGA port that is currently how it is
driven.

dvi-hdmi adapters are cheap.

yuk. switch to dvi.

He will, because his new graphics card doesn't have a VGA output.

My old card does, and it can't quite do 1920*1080 through its DVI port,
so VGA is what I must use. And I couldn't care less.

I tried both VGA and DVI with my previous 1280*1024 monitor, and could
see absolutely no difference at all between the two.

I just had occassion to hook-up a Toshiba 32" tv to a HDMI port. Picture
was terrible with text almost unreadable. Switch to tv's and PC's VGA
input connection and it can be easily used as a big pc monitor it's that
clear. I as expecting much better given prior experiences. As I write,
there is a possibility the hdmi cable I was using is garbage, I need
something else to check.

I use a dvi to hdmi converter running from a pc to another tv and it
works fine. clear as a bell at hd res.

One thing I do find is that with these higher resolutions I find myself
adjusting the icons and almost everything else individually so
everything's not too small. And I wish that method was a little easier
to figure out

then the display wasn't that good. with better displays, the difference

My DP monitor and cards can do 144 Hz. They have both DVI
and DP but DVI is limited to 120 Hz. My DP drivers load
after Win is mostly loaded so I cannot get into the bios
with DP and use an old VGA monitor for that. DVI can get
into the bios but can't keep the DVI cable plugged in
because both the card and the monitor will revert to DVI
instead of DP.

I don't know if any displays were that good at the time. Mine was
Samsung, a 19" TN panel which quickly developed a couple dead pixels
near the bottom of the screen. Oh, look, there's another one. Then a
smattering of them, and I'm starting to feel unlucky but at least
they're dead down at the bottom and not stuck on bright green right in
the middle of the screen. Then the backlight burned out within a couple
years anyway, and I bought this wonderful LG 23" IPS monitor that is
still perfect after at least two or three Samsung lifespans, and VGA is
bitchen.

Hi Tim,

Resolution wise, I can't tell the difference between HDMI and
D-Port. I adore the snap clip on D-Port as they don't fall
out the back of the monitor and/or computer. That being
said, I have never had an HDMI jack come lose.

I notice about a 10 to 20% better picture (clearness) with
HDMI/D-Port over VGA. Myu customers notice it too, but
that may be them responding to my exuberance.

I would use an HDMI to D-Port converter. Start Tech excels
at this kind of stuff (don't buy their USB cards).

https://www.startech.com/AV/Converte...-adapter~HD2DP

Make sure you have a spare USB port co-located for power.

Tip: both HDMI adn D-Port will carry digital sound. Windows
Nein (w10) will pick only one. It may even pick you analog
sound card on your motherboard. If you go into control panel,
sound, you can choose which one you want.

And Tip: you have to go into your monitor setup using those annoying
menu buttons on your monitor and tell it your sound source is digital.

I personally adore my Yamaha speakers.

You didn't tell us the native resolution of the monitors.

DVI-D ------------------- DVI-D monitor (dual link for 2560x1600 ???)
(single link for 1920x1200 ???)

DisplayPort --+--- active_adapter --- VGA $20 (uses +5V on DP cable)
|
+--- passive_adapter --- single Link DVI-D
|
+--- passive_adapter --- HDMI

HDMI ---------+--- active_adapter --- VGA
|
+--- passive_adapter --- single Link DVI-D

Active_adapter have a chip inside the cable assembly or
lengthened connector, that "converts" formats. The cable
has +5V power for low power items, and that's how the
chip is powered. There have been some adaptation devices
in the past that use a USB cable for additional +5V.

Passive_adapter rely on the probing of the monitor to
uncover what adapter scheme is being used. Passive is "just wires".
No power is used. Passive is generally used between
a digital_source and a digital_destination.

There might be some active_adapter devices for making
dual link DVI-D, which would give sufficient resolution
to drive an Apple 30" Cinema display 2560x1600 DVI-D or so.
That would be a case of "digital adaptation" at high
speed, and a "remapping" to make the two necessary link signal sets.
If the dongle needs a memory chip and has a one or two
frame time "thru_delay", the dongle will be marginally
more expensive. (They can't always economically fit the
RAM for a frame buffer, inside a dongle adapter, so it's
a two chip solution.)

If you're playing first person shooter games, you likely
wouldn't do what is in the previous paragraph (too much
thru_delay).

The Wikipedia article for DVI will explain the resolution
limits on single link DVI versus dual link DVI.

*******

At low resolutions, you can't see the difference between
VGA and one of the digital methods. As the resolution
rises, there are reflections and ringing on the VGA coax
wires which make the digital cabled version of the image
look like the better option. Digital doesn't degrade in
exactly the same way as analog VGA.

On the video card I purchased at the end of last year, I use this.

DisplayPort --+--- active_adapter --- VGA $20 (uses +5V on DP cable)

The resolution is 1440x900 on a cheap monitor, and it
looks fine. None of my monitors have a wealth of
connectors on them, so you take what you can get here.

And this is the year to stock up on adapters. Don't
wait five years to go shopping for a second one, as
eventually they'll disappear from the market. We're
at "peak flux" in terms of the adapter mess at the moment.

yuk. switch to dvi.

I have to, the new card does not have a VGA output.

I won't have that problem since neither of my monitors have speakers. I
have a quite nice 5.1 speaker setup using the MOBO sound ports.

My primary monitor is 1920 x 1080 and my secondary monitor is 1600 x 900.
That one is mainly email and a couple of status monitor programs there is
nothing very demanding going on there.

Right now I am leaning toward an HDMI to DVI-D passive cable. According
to my research, the digital signals are all the same, with the only
difference being the type of connector on each end. And like I said in a
different post, no sound to worry about.

The short answer is, it doesn't matter. They're both digital connections
and will drive the monitors equivalently. DVI -- to HDMI is probably
easier/cheaper to find.

that's correct, which is why such adapters cost almost nothing and they
all work the same.

Both HDMI and DisplayPort carry sound over the wire if that makes a
difference and both can do 4k (3840x2160). However, HDMI is limited to
30FPS as far as I can tell whereas DisplayPort can manage 60FPS at
that resolution.
