What monitor input are you using HDMI or DVI?

[fastman]

Is there a benefit with one over the other?

 

[Gloomy]

Yeah, one respects your freedom and the other is party to the scourge of the computing world.

 

[Fallengod]

lol...

I believe DVI is capable higher resolutions and at like 120hz, so you would need dual-link DVI for that. I dont think HDMI can do that. Past that, pretty similar. HDMI can have sound, ethernet through the cable, DVI cant. Typically people use DVI connections for computer monitors.

 

[poohbear]

DVI here. Who uses HDMI for sound??? lol i'll stick to my $200 sound card thanks!

 

[natto fire]

My monitor only has two HDMI and a VGA 15pin Dsub, so I go with the HDMI.

 

[Elcs]

HDMI. No DVI input on my TV.

Optical for sound to my receiver.

 

[MTDEW]

DVI here.

Always wondered about those using HDMI for sound, since monitor speakers always suck.
And you never really hear anyone mention how good/poor the sound output is of a pc video card and if it effects performance at all.

Me, i just disable my video cards sound in device manager and forget about it.

I think HDMI is only good up to 1920x1080 and 60hz. Above that you need display port or DVI.

 

[Will Robinson]

Display Port ftw!:biggrin:

 

[reallyscrued]

VGA.

Don't know if it's a problem with my 4890 or something but all Frostbite engine games (BC2 and BF3) refuse to run at 60 hz at the 1920x1080 resolution on HDMI. It looks visibly interlaced (extremely dark) not to mention my TV resyncs itself labeled 1080i.

On VGA, no such problem.

DVI. Single link for my 27", dual link for 22" 120hz.

 

[KingFatty]

I use both: DVI from my desktop computer, and HDMI from my laptop's dock. So, the same 1920x1200 monitor can display either input, I just set the source selection to manual and toggle using the source selection button.

But now I have a question about HDMI audio and the quality of the sound card in a video card:

How good are video card sound cards?

More specifically, is the sound card in a video card like the 5XXX series AMD better than the el cheapo sound card built into the typical motherboard?

Are the sound cards built into the video cards similar in quality to the el cheapo built-in mobo sound cards?

My monitor would allow me to plug in my speakers or headphones into the monitor, and the monitor could get the sound through the HDMI from the video card, but I've never tested it for quality.

If anything, would using the video card sound card remove some burden from the CPU and technically give you a tiny bump in performance? Do you enjoy a benefit similar to using a discrete sound card when you use the video card sound card instead of the integrated motherboard sound card?

I have HDMI going to my 120Hz TV, am I missing something?

And, along the lines of what I've read here... what's the deal with 120Hz monitors and 'dual-link' DVI? I tried researching it but haven't been able to make heads or tails out of anything I've read (from an end-user point of view.)

I'm using Displayport.

They're all digital, which means as long as you're within the res / refresh that the bandwidth can handle, they're all going to be the same in terms of quality.

The only major differences are:
HDMI can carry sound
HDMI charges royalties, while DP and DVI are open, and do not.

120 Hz TVs do not use 120 Hz source material. They use whatever source material they have, delay the display of that material so they get multiple frames, then calculate what they think should be in-between frames for 120 Hz, then display that at 120 Hz.

120 Hz monitors are actually 120 Hz.
120 Hz TVs are, at least to some extent, marketing BS.

I'm not totally enamored of DisplayPort, at least on Windows 7. When a monitor goes off, Windows removes its desktop space entirely, which annoyingly rearranges my desktop icons and open program locations (especially when everything on my 1920x1200 gets moved to my portrait-rotated 1050x1680). I haven't moved my main monitor back to DVI because it has a setting to keep polling the PC even when turned off, which prevents that behavior, but it's still irksome and wastes power.

 

[taltamir]

HDMI is a single link DVI over a shapelier cable.

What a bizzare and stupid thing for windows to do...
I can see why it would be an issue.

Video card-Sound Cards...

 

[taltamir]

AFAIK the radeon cards do not have a sound card in them, rather they simply carry over the audio generated by your mobo soundcard over their HDMI link.

that makes sense, I just remember there was something that loaded drivers for audio for the video card... I guess that's just for the sound re-routing functionality.

Then why the heck do the darn things need those AMD HD Audio drivers installed?

how else are they going to reroute the audio without a physical cable?

Although, I do not remember my source on that one so maybe its bunk. Anyone here with an AMD card that uses HDMI? If you disable your mobo's audio controller (done via bios) then we would know whether AMD includes an actual audio processor or just a reroute driver.

Yeah, i'd like to see that since i have no clue and googling isnt much help.
I'll look and see if i have an extra HDMI cable here to see if i can experiment.

 

[piasabird]

Cant say much for AMD since I dont use that except when I use a video card maybe. I am using a Intel 2500k with Intel 3000 HD Graphics.

Most monitors use a separate sound and video connection, so there is no real advantage to using HDMI. HDMI is plenty fast for most video at higher resolutions. If you want sound and video try using a LED or LCD TV. Nothing like a $999 40 inch 240hrz 3D HDTV Monitor. A lot of these new TV's also have capability for Wireless and Ethernet.

You might also look for displayport. I have both Displayport and HDMI as well as DVI on my Intel DZ68DB Motherboard.

Here is something I found about both HDMI and displayport. HDMI Vers 3/4 can handle higher resolutions. Some versions may be able to handle 3DTV or 2 separate video streams.
