hdmi output

Whats the HDMI port for on my card?, is it for my tv monitor?

I use DVI at present is it an improvement using HDMI?

[Krusty]

If you are using DVI, stick with that. HDMI is another format. Often used for connecting TVs and large scale LCDs (like your living room flatscreen to your PS3, for example). It combines audio and video. However, I find DVI a bit less complicated. I've run into resolution issues and quality/clarity problems hooking laptops and computers up to a HD TV with a HDMI cable. I doubt DVI would have had the same problems.


EDIT: HDMI is being replaced by DisplayPort on video cards nowadays.

thanks

Actually HDMI and DVI are the same, but different.  HDMI carries sound with the signal, DVI does not.

However, DVI for a television and DVI for a computer monitor are different, even though they have the same pin outs for the connector.

Does that make it as clear as mud?  Aren't standards great?!?

HDMI also includes HDCP (for DRM), which Im fairly sure DVI doesnt ...

[Skuzzy]

HDCP works over DVI or HDMI.  If the content is HD, it requires HDCP support to display it in HD formats, whether the physical interface is DVI or HDMI is irrelevant.

Plugged my HDMI Samsung syncmaster fullHD tv/monitor into my GTX560 instead of using DVI and the picture quality had improved vastly.

DVI seems to be inferior to HDMi, there was a tearing in game when using DVI.

The game graphics have improved (radar towers are highly detailed etc)

Hurrah!

Oi.  DVI and HDMI are identical, from the same source (ie computer HDMI/DVI are identical, television DVI/HDMI are identical).  HDMI carries audio and video.  DVI carries only video.

Now, that said.  The computer DVI interface is not eletrically the same as the television DVI interface.  To further complicate this, many television monitors will auto-adjust the signal to match the computer interface, when it is sensed.  The last wrinkle is there are video cards which will auto-sense and switch to television mode when they detect a television monitor attached.

So, whoever wins is what you get.  It could actually change between reboots.

Then again, if neither will convert, you end up with a mess.  That mess would also be on the HDMI port, as the video signals are the same, if the device is equipped with a DVI port.


zack, the only thing that could change between DVI and HDMI, in your configuration is who won the battle for which version of the DVI signal to use.

I was having problems starting pc ( blue screens, pc rebooting when at windows desktop) i tried HDMI which touch wood has stopped these problem.

I set up my old Dell dvi monitor for a couple of days and noticed blue screen etc did not occur.

I also went to my windows updates and noticed that there was a windows update for my Samsung monitor/tv, i have read on forums never to do this


I changed from ATI4850 to a GTX560TI, problems started when i changed cards, its all good fun

You're forgetting about some DVI interfaces that actually use an analog signal.  I doubt this was the case with him, but there are some hardware that can support the analog VGA signals through the DVI cable.  This is a feature that HDMI does not support.  Who knows?  Maybe his VC was going this route and switching to HDMI forced it to use a digital signal instead. <shrug>

Now see... as I understand the standard HDMI does not support analog. Is it possible that a monitor defaults to analog even though digital is available? I wouldnt know... but I hear this claim that HDMI makes images on monitors much sharper over and over.

Oh how I loathe HDMI.
 

[TequilaChaser]

so if I am using an ASUS VE 27" widescreen monitor that supports both DVI and HDMI and my videocard is an XFX 6870 1 gig DDR5 that supports both DVI & HDMI ( and display ports as well ), which is the better way to go?

DVI or HDMI?

if I use HDMI, will this affect my sound? since I am currently using my on-board sound chip on this new PC I just put together.....


am currently using DVI  @ 1920 x 1080 32bit 60 Hz refresh...... will HDMI be better?

what will the HDMI refresh rate be?

side question:
has anyone ever put together a new computer and had what seemed like a funky burning smell the first 2 or 3 times they started it up? I did, and am some what worried, although the smell has seemed to gone away.... and thinking it was coming from all the new parts.... hoping it was, everything seems to be running just fine..... visual inspection of all components and wiring looks ok.....

Doubt you'll see a difference between DVI and HDMI, as Skuzzy mentioned above HDMI was basically built on top of the DVI standard.
