DVI vs HDMI?

[btarunr]

If you're not looking at the audio pass incentive (i.e. one wire that heads to your HDTV), then neither is better for a PC scenario. HDMI passes video in the same low-level format as DVI.

 

[Mussels]

No, I am saying that HDMI server no practical purpose over DVI that can be seen as a tangible benefit to the end user. In particular those users with monitors that offer no audio support. And your audio inferior comment is specious. PC LCD monitors that do offer some sort of audio (via mini jack, speaker or otherwise) are not known to offer high fidelity audio .

but many, including TV's offer high quality pass through.
One cable from PC to screen, one cable from screen to speakers.
who cares about quality anyway? i use my monitor speakers for VOIP and voice chat, and my TV is just a passthrough so that my PC, wii, and housemates PS2 and 360 can all be input into it, and passed out into one set of speakers via the one cable instead of each device requiring one input each.

even if HDMI serves you, or thousands of people no purpose - it only adds features. it doesnt subtract. worst case you got exactly the same as DVI, with a connector 1/4 the size.

imagine USB the size of DVI, and you'll get the point there. its a convenience, not a neccesity - but it little things like that that make one type more preferred than the other to the casual user.

I have an Asus M3A78-CM motherboard with VGA , DVI and DisplayPort that can use 2 plugs at the same time and is Hybrid CrossfireX (what the heck is that??? ). For now i use only DVI but later when high resolution screen will come out i will get one...who cares it brings no sound ...i will only use the 8.1 onboard sound to do some surrond. Ok it will take many wires for sound but tie-raps give you a big wire instead of many smaller ones
2560 X 1600 resolution on DVI and display port..i wish i could get a screen with that much resolution but i need more bacon

hybrid crossfire means you can crossfire the onward with certain dedicated cards.

DVI + analogue onboard = good video and audio
HDMI = good video and audio

Both have equal quality! however, if your hardware supported the choice - would you take one thin cable, or 3 thin cables and one chunky one?

I dont know but i have 6 plugs on the board for audio. 1 the micro, 1 the input and 4 others for surrond including the green one for single plugging. ill see later....anyone ever seen a 2560 X 1600 resolution able screen? if yes send me the link even if its tv with display port or computer screen. thx

thats the highest resolution screen i know of.

 

[MohawkAngel]

Still not enough i will wait anyway my hardware are good phenom x2 am3 550 BE with 4 gigs of ddr2 800 pc-6400 so it will be enough for a long time considering that i play only Battefield 2, work on it and use it as home theatre pc.

First DVI-I is dual link digital and analog supported. and should be capatible with all monitors made in the last 2 years or so.

Correct. If you have a HDMI 1.3a cable it will support anything that specifies any version older than itself. So a 1.3a cable (90% of the ones on the market) will work in a 1.2, 1.1, etc. device no problem. The only change was was improves in how the signals get transferred which resulted in higher bandwidth, higher throughput. The actual plug has never been changed and never will be changed. They added a clause in the standard to not change the plug except for the rules about HDMI mini port, but no product I know of has used that yet. See link below.

http://en.wikipedia.org/wiki/HDMI#Versions

DVI can support up to 2560 x 1600, but the higher the resolution, the lower the maximum refresh rate. At say 1280 x 1024, both DVI and HDMI will refresh at up to 75 hz, but at 1960 x 1080 (i think that is right) DVI will be limited to 60 hz and lower, while HDMI will still be capable of better. Hell they may TV's now with 120 hz refresh rates on HDMI.

DVI dual and single link doesn't effect bandwidth. A DVI dual link will support both analog and digital signals (DVI-I). A single link (DVI-D) will only support digital signals. There is a whole bunch of other variation and rules about linking which kind of DVI cable to what, but honestly a PC monitor only needs one link that is digital, yet most GPU's have DVI-I links on them for people who still use there VGA only monitors.

There was a plan to use the second link in DVI-I to carry a audio signal, but I think it was abandoned when DisplayPort's specs were finalized. If they are still working on it, basically the video will be on the digital link on the DVI-I and the audio will be transmitted as a second analog signal on the link that is normally for a VGA signal.

None of those TV's accept a 120Hz input. Their screens output 120HZ, but they can't take a 120Hz signal from your computer.

my 24" is one of those. it has a 120Hz panel that accepts a 60hz input, and merely doubles the frames.

No idea what purpose its supposed to serve, but thats the way it is.

 

[Wile E]

He is.

Look you will need an adapter and a video card capable of audio pass through. Which you have, you just have to connect the SPDIF wire from your card to your mobo. A DVI to DVI link cannot have audio. DVI (with adapter) to HDMI can have audio. Before you ask why.....its complicated.

All this mess just proves the IEEE point. DVI is too complicated and HDMI simplifies stuff. DisplayPort will simplify it even more.

Not with ATI cards from 2900 and up. They have built-in audio.

As far as the overall debate on which is better to the standard PC user. Neither is. They both offer the same video quality. HDMI only shows benefit when you consider audio as well, but most people don't need to worry about that anyway.

That said, I prefer DVI on my non-HTPC computers, only because I find many HDMI monoitors to not sleep properly when using HDMI, they go to a blue screen instead of going into standby. Not a fault of either standard, just a weird quirk I noticed.

hey, australias a little behind on $40,000 TV's and $2,000 PC screens.


the USA dell sells samsung and NEC screens? the hell?

 

[Wile E]

That survielance TV is just 4 28" 1920x1080 screens crammed into one housing.

It only needs 2 dual-link DVIs to push it...

lol. or 4 single link.

Furthermore, one would need to actually know which HDMI version that PC LCD monitor supports.

That is actually completely wrong. You do not need to know which version of the HDMI standard your monitor supports. That is something it will take care of on its on. You just get a 1.3a cable (most on the market) and it will just work. And as Mussel said, even some of the old cables from back in the day will still work for most, if not all, applications.

The new 1.4 standard rev. just increased the product range the cable can be used for. larger format screens (72" and up). For computer monitors, this rev. will not be necessary.

On that note, as far as picture quality is concerned, you are right. There is no benefit from switch from DVI to HDMI if you monitor has both and no speakers. Mussels was simply stating this is subjective and all things considered, there are benefits for others.

Not with ATI cards from 2900 and up. They have built-in audio.

I know. That statement was specifically for the guy that asked and he has a Nvidia GTX 285. So for him, he will need the SPDIF cable that came with his card.

oh good i think ill get another LG with high contrast for nbetter color and quick 2ms response like my flatron ...it would be ass kicking home theatre but ill have ot wait for a monitor of high resolution with display port wire

 

[TheLaughingMan]

I think it is funny Apple added DisplayPorts to a lot of their products a few months back, but there are currently no devices on the market that uses the standard. If I am not mistake, they will start releasing DisplayPort stuff starting next year.

 

[FordGT90Concept]

I said earlier that the reason they did that is most likely for design sake. Apple hates holes in their cases and DVI is a huge hole compared to DisplayPort. They don't care which is better as long as the hole is smaller. That could be the same motivation for Firewire too (they didn't like big serial and parrallel ports).

Apple = form before function.

Display port vid cards have been out for 2 years

[Soylent Joe]

If they made HDMI cables more flexible and harder to come out, then I'd hook my monitor up with it, but it's just to clunky for me.

Yes, graphics cards have been out with DisplayPorts for years. Now go TRY to find a monitor to connect it to DisplayPort.

I retract that statement. I found 4. 2 by Apple and 2 by Dell. A link to one is below.

Besides this is something to discuss on another Thread.

 

[FordGT90Concept]

They have DisplayPort on that monitor because 2560x1600 @ 60 Hz is the maximum of DVI-D dual-link. They don't list the refresh rate so it's not certain if one would benefit from using a DisplayPort cable or not. Since they included the port, I have to assume it is capable of greater than 60 Hz at that resolution.

 

[TheLaughingMan]

You make a good point FordGT90Concept, but I was just shocked to find something to plug into a DisplayPort period.
