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?
-
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 :aok

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 ...
-
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 :cry
I changed from ATI4850 to a GTX560TI, problems started when i changed cards, its all good fun :banana:

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.
:lol

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.
-
I havent taken one apart yet but I would bet the only difference in a monitor that has HDMI and one that does not is the presence of speakers. I think its like the same effect you feel after washing your car and putting a good wax job on it. There is no difference in reality but you "feel" like it drives better because you want it to and not because its cleaner and has wax on it.

For your sake I hope it was the thermal pad of the cpu heatsink 'curing in'. If the funky burning smell was that of a condenser then expect rapid failures on random items, especially if the source was the power supply.
-
Condenser? Please post a picture for me. :D
-
I think my Gtx550 ti is moody its causing boot up problems, read somewhere about upping voltage on GPU might sort out problem.

I used artic Silver 5, the heatsink/fan is a corsair A70 with dual 120(135?) mm fans on an AMD phenom II 975 3.6ghz quadcore
power supply is a PC Power & Cooling 80% silver certified 950 watt Siliencer II
everything brand new........ smell is gone........ all voltages look perfect........
is there any other testing or possible software I might could use to monitor or troubleshoot the different components...... I am starting to think it was that everything was brand new...... Case, CPU, PSU, Memory, Vidcard, Case fans, BR Burner, BR player, media card reader, MB, HD etc........
Thank You for the replies.... I hope to get AH loaded today to see how it performs.......

Here's a link to some good articles about HDMI and other cables, bear in mind it is a cable vendor who published these but in general I find them to be a pretty good explanation of where HDMI came from, how HDMI works, and some of it's shortcomings.

Lol sorry translational brain fart, meant capacitor obviously :D

Yes... probably you wont need to though. You can get a cheapy PSU tester but they are the equivalent of an idiot gauge on your car. The only real method of testing PSUs is with an oscilloscope. What Ripley is describing is a capacitor that has leaked. That could happen I guess but in the case of PCP&C it would be unlikely. Probably what you smelled is the pasty substance used during a soldering process of assembly. I would test the PSU for dead lines or ripple but in the case of ripple you would almost certainly be able to hear it over your sound card. If a visual inspection of the MB doesnt reveal any swollen capacitors then your good to go. If you start to see problems with data loss then replace the PSU.

I've posted this software before, in the Hardware/Software section.
It tell's real-time temps of your MotherBoard, CPU, Graphics card and Hdd.
At least you'll have a pretty good idea of what's getting hot, if anything.
