Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

im not trying to be an ass either - its a quick read and there's lot o info about the technology there...

Also Apple.
1. support for higher resolutions. thats interesting.
i got my new monitor, and it came with a displayport cable. what can i expect when using it instead of the normal dvi connection? (and i know i have to have the video card connection also!)
5700/5800/5900 series of radeons support native display port

Okay...
DP can use one clock gerator for several outputs.
HDMI needs one per output.
DP = cheaper
DP is royalty free, too (dunno about open standards).

Yeah, stuff like daisy-chaining DP displays and direct driving is what makes DP so interesting for both consumers and manufacturers alike. The only reason to add HDMI is for a kind of legacy compatibility with HDTVs and such which have only HDMI (HD) input.
Displayport v1.2 was just announced. If ATI/Nvidia videocards support v1.2 then you can go triple monitor display from one video card output.
- The conerns on the Nvidia front about two video cards for three monitors may be from a lack of connectors. This can be easily assuaged with a single DP 1.2 port.
- You gain a modern connector that helps with portability. Mini-DP ports are handy for notebooks wanting a second display.
- Imagine on a notebook or desktop being able to output a 4 monitor signal from one regular DP v1.2 port. On the notebook front, that's pretty convenient and unobtrusive, no matter how unlikely you'll be hooking that up. On the desktop side, things like adapters and extensions are reduced quite a bit due to daisy-chains off a single output.
Of course, there is the limitation of only 5.4Gb/sec for each monitor in a 4 monitor display, so you'd be limited to about 1920x1200@75Hz or 1680x1050@120Hz for each monitor. But I don't see that as being too restrictive for a single output.
But of course, this all requires DP v1.2 monitors. Even though the specification has been released, who knows when this will come to fruition.

IQ is going to be more or less the same with all digital connections. HDMI, DVI, and DP will all have identical image quality.
ATI isn't forcing anything. DP is simply the natural replacement for DVI. VESA made the specs for both. DP also has higher bandwidth than HDMI. You can bet your ass Nvidia will be fully supporting it as well. Also, ATI and Nvidia both support HDMI, so both are letting consumers decide. Get off your soapbox, please.
They will all be obsolete when lightpeak comes along. What we need is one standard low latency interconnect like lightpeak, and then one standard low latency wireless interconnect for devices (displays too) and networking. I'm sure laptops could get even smaller beaming wireless signals from mb to screen/touchpad/keyboard. But I'll just have to dream for at least the next 5 years.
And what exactly do you get with HDMI over DP?
DP is cheaper to develop and easier to implement. It can also pass audio just like HDMI. From a technological standpoint, it lacks nothing (to my knowledge) in comparison to HDMI. Enlighten me if i'm wrong. The only thing it's lacking is widespread support, which admittedly, is a bit of a let down.
That has no bearing on the OP's question. As exciting as LP is, it's irrelevant. Furthermore, most information to date touts the benefits of LP's physical properties, as no protocols, connectors, or compatibility have been defined.
Displayport hasn't been forced on anyone. You'll notice that you get the same connections AND Displayport. Adding DP to your computer or video card is actually easier and cheaper than HDMI or DVI, and better suited to the smaller fab processes being used. DP should actually get implemented in front of HDMI and DVI protocols and being converted to these outputs. DP was used long before ATI brought it into the public's eye.
True, but his question has pretty much been answered.
