Why has dual link DVI TAKEN SO LONG!!

[imported_goku]

Why has dual link DVI taken so ****** long to be implimented into video cards??? The standard has been around forever and the room was there for those few pins needed for dual link, so why has it taken the industry so ****** long to do this? This means cards as new as the X850 are single link only, wtf is this ******? DVI has been on video cards for a long time now, why couldn't they have this function when video cards were FIRST coming out with DVI?

1) Demand - How many people have stupidly high res monitors

2) Cheap Manufacturers - Combined with low demand to save a few pence they dont implement it

Not to justify it but this is likely why, it sucks really

They need to just increase the speed of single link dvi. DVI is actually a pretty old standard since it was based off of some preexisting quasi-standard from notebooks wasn't it?

Done.

Dual-link DVI is flat out irrelevant for 99.999 percent of the market. Up to 1920x1200 it's not needed, and how many people who afford a 30" hires panel will complain that their $50 graphics card doesn't have the right linkup?

yeah , it is jus tnot really needed for 99% of people.

Well I paid $400 for my Radeon 9800 pro, why couldn't it have it on there? The high end cards of '01/'02 could have had them, that way you could drive that IBM display with 9 megapixel resolution.

could you even get a 1920*1080 computer monitor in 2001 for under $10,000?

The Sony FW900, but that was a $2000+ monitor then, not exactly commonplace in the consumer market.

the fw900 was an analog monitor though wasnt it? you could not use dual link for it anyway. back when the 9800 pro came out, you could not even BUY a 30" lcd.


30" lcds only just recently (lastg 2 years) came out . there are STILL only 3 of them on the market (dell, benq and apple ) witht e25x16 res.

Good point about the Sony, and I didn't know about the BenQ. (Dual) Link us up?

i had just assumed it was already out on the market, but i guess not. but i remembered reading about it and here is a link mentioning it with pictures.

i would assume itll be out soon.

Sweet, if it's got component I may pick it up instead of the Dell 3007FPW for my HTPC (currently on the 2405).

Even if you could have, 1920x1080 still does NOT need dual link DVI. Up to (and including) 1920x1200 is done with a single link.

Yea but at resolutions past 1600X1200, dvi doesn't do so hot with single link. You basically want dual link past 1600x1200.

What the hell are you talking about? DVI-D either works or it doesn't, regardless of resolution.

Sorry, but like I said earlier I've driven my 2405FPW with as little as a PCI Radeon 9100 on DVI. Worked just fine. What kind of cards have you observed these problems on? Many GeForce cards have issues with high-res DVI.

Besides, what makes you think dual-link's full capability is going to go to work to drive a resolution below where it's needed?

 

[imported_goku]

Here ya go.

http://en.wikipedia.org/wiki/DVI
"Example display modes (single link):

* HDTV (1920 × 1080) @ 60 Hz with 5% LCD blanking (131 MHz)
* UXGA (1600 × 1200) @ 60 Hz with GTF blanking (161 MHz)
* WUXGA (1920 × 1200) @ 60 Hz (154 MHz)
* SXGA (1280 × 1024) @ 85 Hz with GTF blanking (159 MHz)
"

** Please disregard. I went ahead and posted this question as a new thread **

Sorry to ask such a basic question but I'm having trouble find the answer to this question about dual-link.

Let's says that I have a 7900GT which has two DVI outputs and it does support dual-link. Which of the following is correct:

1) It supports running two DVI monitors each with a maximum resolution of 2560 x 1600.

2) It will only support a single monitor when running a dual-link capable monitor above 1920 x 1200

I guess I'm confused by what the term "link" implies. This tends to make me think that when you run a monitor above 1920 x 1200 that it has to harness all processing power together and can only run a single monitor.

Thanks for any clarification that anyone can provide.
