HDMI vs DVI

[jeramyRR]

Is there a performance or quality difference when using DVI connections instead of an HDMI connection? I just bought a video card that has 1x mini-hdmi and 2x DVI connections. Also will using a hdmi to mini-hdmi dongle hurt anything?

 

[bunnyfubbles]

they're both digital connections, there will be no difference in quality

dual link DVI has more bandwidth and can thus drive more demanding monitors such as 2560x1600 / 2560x1440 or a 1920x1080 monitor @ 120Hz, HDMI doesn't have the bandwidth to drive such monitors, but it can do a 1920x1080 @ 60Hz TV/monitor just as fine as DVI.

on the flip side HDMI can carry audio signal

HDMI can go up to 4k, but I don't know if any video cards or monitors are using it.

What does that mean, "Can go up to 4k?"

I have two really nice Dell Ultra Sharp 24" monitors. I'm a gamer and a 3d artist. Will using the two DVI connections hurt that?

No.

You can think of HDMI and DVI (more specifically DVI-D) as being essentially identical in image quality for your 24" monitors.

You can just ignore it. He's talking about a resolution for which monitors do not yet exist.

Anyhow, for the Dell 24" monitors, HDMI is just as good as DVI. In fact technically HDMI is just a higher bandwidth implementation of single-link DVI (which is all that's used for a 24" monitor).

I've had intermittent failures, when using a HDMI-to-mini-HDMI dongle adapter, I would recommend getting the correct cable instead. Good advice too, instead of using a DVI-to-HDMI adapter.

Well HDMI and DVI quality is same. The difference is HDMI also transfers audio as well. the nvidia audio chip embedded into cards. thx

Somewhat off-topic, but there is at least one 4K monitor that will be available soon: http://www.elecomsystems.com/product.asp?pf_id=Coronis_10MP

That display is just grayscale ?
no color ? and they want $22,000 .... lcd fail

It is for medical use, if the matter is between life and death i dont think $22,000 is too much. Especially for a 10MP screen.

Excessive number of resolutions can cause eye/brain fatique. I would not suggest staring at the screen with ultra high resolution for a long period of time.

Overall (in terms of compatibility), DVI wins. K.O.
HDMI cannot give you 1:1 mapping when hooked up to a 768P native res TV's. It will give you 720P instead, and deteriorate's the picture, resulting in softer / blurry images. DVI-D will give you 1:1 mapping in this scenario, as well as 1920x1080 configuration.

HDMI is more favorable for consumer TV users.
DVI-D is more for businesses and pro users like me.


Thank you,

There's not a single thing in this post that you got right.

-Hi res doesn't cause any problems here in real life, where it's infinite
-HDMI and DVI are identical

Not to mention that some TV's do in fact support 768p over HDMI, AFAIK.

 

[Skurge]

Are they any cards that can do 4k?

 

[96Firebird]

I believe we had a 4k monitor at my old co-op (Carestream Health, they specialize in medical imagining). One time I was chosen to do a "spot the difference" between two images because they were trying to see how precise their equipment had to be before it was actually noticed...

 

[jeramyRR]

Thanks everyone for all the replies and info. I'm glad I'll be fine using my DVI connections.

Mine does. Whomever thought that HDMI could *only* carry 1080P and 720P is wrong. Clearly.

Seeing something in real life is not equal to seeing something on a monitor. I have read somewhere a while back that if the res is excessively high it can cause some sort of ill effect on your eyes and / or brain.

-HDMI and DVI are identical

Identical in what?? Don't get too vague on the subject matter.

Identical in terms of digital data transmission? Yes. Identical in terms of compatibility (driving to specific resolutions such as 1:1 pixel mapping to deliver best IQ/PQ), no. It depends how you word it. Just saying "they are identical" means nothing.


lmao

HDMI will provide other resolutions, but will not give you 1:1, meaning no square pixels. You can have other resolutions over HDMI but will give you soft blurry images. I guess you love blurry images. In that case, you shouldn't worry.

Your FOS. The monitor returns the resolutions and refresh rates that it supports using EDID over HDMI, and the video card then programs those modes and sends the data over HDMI.

I get 1:1 just fine over my HDMI on my HTPC. Text is plenty sharp.


Edit: It should be noted that some televisions are deficient when using HDMI, and will not do 1:1 over HDMI. This is NOT a limitation of HDMI, but entirely a limitation of the TV. On my friend's Sceptre 32" 1080P HDTV, he had to find an advanced option to set the HDMI input to 1:1, to disable the overscan. On my Westinghouse, no setting is necessary to get 1:1.
