ATI only for 1920X1200 res?

This appeared in an Xbit article:

For users of widescreen high-end liquid crystal displays (LCDs) the only choice among the premium graphics cards are solutions by ATI Technologies: even though they consume more than the product by Nvidia, the latter does not support dual-link DVI, which is required for resolutions higher than 1600x1200 at 60Hz on LCD for monitors with digital connectors.

Is this true? If so, I just reamed myself by buying the GTX (with intent to upgrade to the 7900.)
 
not true, I would say that any modern card with a single link dvi output will manage to do 1920*1200, The GTX have one dual-link dvi output anyway, so it could drive a 30" monitor at 2560x1600.

edit:
If you plan on running 2 30" monitors you should look into the x1800+ cards since they got 2 dual link outputs.
 
no, it is not true. The 7800's have dual links just like ati's do. And the spec about 1600 x 1200 is wrong...I personally got corrected about that recently. 1920 x 1200 even over a single link is perfectly fine. And for those monster 30 inchers ATI has nothing over Nvidia.
 
ATI was the first to have it, but nVidia has it now as well. That Xbit article must be dated.
 
I posted a comment as Sproketz letting them know how wrong they are about the Dual-Link missing from the 7800 series as it's listed as a feature of the 7800 series on nVIDIA's features and benefit's page.

Clearly they didn't research well and it calls into question the quality of the rest of the article.

I'd skip it and move on to a more informed set of reviewers (like HardOCP :D )

I can agree with that, but ot's also the refresh rate. These new monitors with 11 ms refresh put native 85 HZ at 2560x1600, nvidia doesn't support that.
 
The 7800GTX can run a 2560x1600 monitor. However, it can NOT run 2 such monitors because only 1 port is dual-link. The other is single.

(Last paragraph)

The X1800 series and above can run 2 such monitors, so they are the obvious choice for such a setup.

In addition, the X1900 series of cards has 50% more on-chip memory for Hierarchial-Z than any other gaming card in the world. Without that extra memory, no matter HOW powerful your card is, you WILL get a significant drop in gaming performance at high resolutions.

It's just that the nvidia doesnt have two dual link DVI ports, only one, and ATi has two Dual Link DVI ports.
 
Were not disputing the X1900 and X1800's capabilities, but the article is written in such a way that leaves one with the impression that the 7800 cannot support a dual-link monitor at all.

Also who can afford two of those types of monitors? Adopt me! :D

Yeah, the article is definitely wrong and should be corrected.

But the X1900 series is still King-of-the-Hill for extreme-resolution gaming because of the H-Z and multi-highres monitor support, which is all I was trying to say. :)


BTW, I am currently able to run EVERY Game out there at 1920x1200 with SLI 256mb 7800GTX's, most with 4xAA and 16xAF since those are actually only a very small performance hit. So ATI is NOT required for 1920x1200 by any means. Though I would strongly recommend an X1900XT OC'ed to X1900XTX speeds for any single-card solution.
 
Thank you!

I'm greatly relieved, to say the least. I agree that ATI has THE solution for gaming, etc. at high res - at this very moment.

I love my 9700Pro AIW, but I also loved my GF2 GTS, and for a variety of reasons have decided to go nVidia this round. For them not to support digital 1920x1200 would have been pretty outrageous.
 
The official limit of single link DVI is 1920x1080 (it was designed for HDTV). With reduced blanking (which your driver should handle automatically) you can get 1920x1200 out of a single link port. Anything above that requires dual link.

X1K parts have two dual link DVI ports, 7800 parts have one. Many workstation level cards have two dual link ports as well.
 
So how do you tell what port is the dual link TDMS transmitter on GF7 cards?

I have this oneevga 7800gt

obviously the one that is, will power the higher res.. but is there any other way to tell? i am getting a 1920x1200 display and want to not use the reduced blanking port.
 
Yes beleive everything you hear. Particularly through these forums. Xbxo 360 is much better than any pc and if you have a widescreen monito ATI is the only way to go.


I guess since I'm speaking to hardforum member (mostly post adolencse folk or people pretemding to be) I should mention I'm being sarcastic.
 
Wow, Xbit has really let me down on this one. Hell, this seems like one of those things most noobs would know. The dual link port should be the first DVI port IIRC.

1st DVI port? :confused:

Do you mean 1st port according to the NV drivers? Because otherwise I wouldnt know how to tell.
 
some GTX's dont have DUAL LINK and even if they do only one of the outputs will be DUAL LINK (Quadro's have two). Check the manufacturers website BEFORE purchasing.

Reduced blanking on an LCD is irrelevant, blanking only applies to CRT displays that need time to move the electron gun from the bottom right of the screen back to the top left.
 
Isn't Xbitlabs russian or something? Whenever I read it sometimes I say to myself, wtf did they just say? Sometimes their mistakes look to be language mistakes, not facts.
 
I personally have an evga 7800GT. It has 2 DVI's and I am only using 1 of them to drive my new dell 24" flat panel at 1920x1200.

While the blanking interval itself may have little functional use to an lcd it is still required in the dvi signal (if only to indicate the start/end of a screen).

If the blanking intervals are fairly large like with the GTF timings it can eat a significant portion of the available bandwidth as well.
 
my question is if i got the 30 lcd monster from dell, is one card going to be powerfull enough to play games at that res. say World of Warcraft, maxed out, would one video card run it smoothly?
 
Everyone on this thread is not understanding the difference between what is required to drive a 20-24" Dell LCD and a 30" Apple LCD. The Apple requires dual d-dvi links, which the 7800 series card does not support but the X1800/X1900 series does. In order to get this type of performance from Nvidia, you must go to their workstation line of cards.

Now we shouldn't see more "my 7800GT runs at 1900 x 1200 on my 24" Dell" as it does not apply to the OP comments.

Great question. Either one will work great. Depending on your budget, option two will set you back thousands.

1. X1900
2. Nvidia Quadro series card
