hello all...after reading many informative posts across numerous threads i've basically compiled all the hardware for my new system. this will be my first build i do on my own (as i've owned a dell for years). it seems that i've hit a roadblock on the final components to my rig however. im just about to pull the trigger on the 8800GTX and the
Benq FP241WZ. The main draw to this moniter for me is the inclusion of the HDMI port. I will be using this monitor for games, CAD, Maya, Photoshop and movies. One thing im not fully understanding is the lack of GPU's that include HDMI. Will the new 8900"s have this feature? Does Dual DVI combine the audio and video signal in the same way that HDMI does? My main goal is to be as future proof as possible as i cant afford to by another GPU when HDMI is more mainstream.
 
How about just getting a DVI card and a DVI - HDMI cable?

Basicly the whole HDMI is kinda non relevant to 3D cards as they do not produce sound. So thats probably the biggest reason why there is not many (any?) HDMI 3D cards around. Why have a connector able to move sound and video on a 3D card when your only producing video signal with the card? And also that HDMI connector sucks big time :p
 
I am using a DVI->HDMI cable to my plasma right now. Works like a charm. Also works with HDCP as the 8800 series support HDCP.
 
I also have a DVI-HDMI cable hooked up to my 50" DLP as my second monitor, it works great.
 
I wonder if there is any visual differences between DVI and HDMI. I know some motherboards are coming out with HDMI output.
 
thanks guys...that does make a lotta sense. so i guess the primary reason that the benq monitor has the HDMI port is to connect an up-converting DVD player, HD-DVD or Blu-Ray player? i've just read that HDMI will be the next big thing after DVI. why make a computer monitor with this technology?

couple more questions guys...

sam0t: why do you say that the HDMI is not good on the Benq? Are there different qualities? How do you tell the difference?

And what is the purpose of dual DVI when the sound doesn't come from the GPU?

I've learned a lot already in the last couple weeks reguarding all this new HD tech...but still have a ways to go i guess :p

If your talking about dual link DVI, its to drive very high resolution monitors. HDMI is kinda pointless for GPUs as DVI does fully support HDCP just like HDMI does. Some mobo's might have HDMI output on them in the future that combines both the boards integrated audio and video.

The next big thing for displays will probably be something like UDI, which you can read about below. There is a competing interface for it though but the name escapes me at the moment.

the other one is display port. Personally, we don't need this useless crap yet. These are just people looking to cash in the market and make money off of licensing a product that we don't need.

Hmm there must have been miscommunication here, did I say HDMI is bad on Benq? I meant that sure HDMI is a welcome addition to monitors/TVs but kinda unnecessary for video only producing products like 3D cards. And if your referring to my "HDMI connector sucks" comment that was purely about the connection method of HDMI. HDMI connector has no screws like DVI to attach itself firmly on a connector, sorry my poor english cannot explain it better :)

I think you have somewhere confused the single/dual DVI terminology. The difference between single/dual link DVI is how much they can transfer data and this is directly linked to the Resolution and refresh rate your using.

I suggest you read this wikipedia page, it explains the DVI interface very well :)

thanks for the links guys...yeah it seems like a very cluttered array of options just to connect a display. so since im only going for a 24" LCD panel with a native resolution of 1920 x 1200 the only benifit for me would be:

DVI (1920 × 1080) @ 60 Hz with 5% LCD blanking (131 MHz)

Dual Link DVI (1920 × 1080) @ 85 Hz with GTF blanking (2×126 MHz) (not really sure what that means though)

I currently have a 6 year old CRT at 1024 x 768...:eek:
