if u r talking abt U2311H, DVI and VGA cable are provide by the monitor. So technically, DVI should be superior over VGA due its pure digital end to end connection btw ur gpu and monitor vs VGA's transmission of analogue signal which maybe more vulnerable to EM interference. In pratice, it depends. I would say VGA are ok if they are short. So try what ever fit best for u.

DP to DP cable and HDMI to DVI should technically provide the same quality for u since u r only using it at 1080p res and those 2 are digital output. So just pick which ever suits ur budget

I for one can say at 1080p res and a short 1 meter VGA cable. The pciture quality is fine with I compare side by side btw my second monitor with DVI.

The key factor here is length of cable, build quality of cable and maybe how noisy ur environment (as in electromagnetic interference if u can measure it?).

It also depends on the quality of the analogue/digital conversion of each monitor. Some have better sharpening algorithms for VGA than others.

So what I trying to say is, with D-Sub(VGA, DVI-A) you may encounter degradation of the signal from multiple factors while digital transmission(DVI-D, HDMI, DP) eliminate the flaws in analogue transmission have

does ur GC has 2 output ports? if so, what do u intend to use the 2 monitors for? also, mind telling us what is ur GC?

nVidia cards can only support up to 2 monitor becuz each gpu core can only output 2 clocks.
unless u r using a multi gpu GC like gtx590 or multicard setup.
this is true with AMD cards but DP is self clock so it doesn't use the gpu clock
hence why AMD GC needs to use active DP on the 3rd monitor

No, i think for u case, that EMI is not the cause for the blurry image but I believe ur lappy has a poorly make signal converter. becuz some manufacturers might skimp abit on the signal converters

just wondering where did u get those numbers?

although ppl here highly recommend dell but thats only valid for Dell's UltraSharp IPS line. other than that, you don't see much love for Dell's normal TN monitors.
I would recommend either LG or Samsung if u going for TN monitors since their produce their own panel and other company buy OEM from them

yes. when I ordered my 2nd u2311h, dell has sent me u2312hm cuz they no longer have new stock of it.
u2312hm is definitely lighter than u2311h. and noticeable weight that u can feel it with tilting or swinging the monitor.
In the end, I prefer the more professional look of the U2311H. but i do have 1 nagging problem with the u2311h when comparing to the u2312hm is that the CCFL takes a few minutes to warm up to get to the proper colour levels. becuz of that, the 2 monitors will have 2 different color level at the first few minutes when power on

also add that, it has more aesthetic than the dell ips. so its aesthetic vs functionality

e-IPS are IPS, its just that they cut corners to keep the cost down. but its does not apply to all e-IPS panels, some are true 8bit panels while some like the panels used in the u2312hm are using 6bit+a-frc to generate its 16.7million color depth.
In fact, mostly all TN panel rely on the same trick as well since TN panels are limited to only 6bit color depth(256k color)

but it abit disappointing that the e-IPS in dell's ultrasharp series are not a true 8bit panel but in reality we barely see any difference

I want to believe, I want in monitor form not only on galaxy tab10.1 so still waiting for samsung SA850 but earlier reviews seems MEH~~

Pricing is quiet high. With the level of the H-IPS panels
It a good monitor but it does not bring anything new to the table
But I need to read up more on it thou

LG Display supply Dell the IPS panels for their ultrasharp series

IPS are IPS, no such thing as half IPS. it's not like e-IPS is a hybrid using another tech. but just a easier and cheaper to make version of the tech.
as u say, no one gonna buy a expensive monitor right off the bat, so e-IPS is a stepping stone for ppl to experience the benefits of IPS first and get them hook.

for the 27 inch model, I think Apple Cinema Display and Thunderbolt Display are the only glossy IPS panels.
I also believe that the panels used by Apple are the only glossy IPS panel supplied by LG Display
since LGD usually produce matte IPS panel for their OEMs
You have to blame LGD for the lack of glossy panels since they are the main producers of e-IPS, S-IPS and H-IPS panels

e-IPS that are true 8bit are (from what i find) Dell 2209WA, LG W2220P, Fujitsu P22W-5 ECO, HP ZR24w and Fujitsu P24W-6

ipad2 is a true 8bit ips panel while the asus trasnformer is 6bit with dithering

if u ask me, I would only consider a 32-42 LCD TV as a computer monitor if the panel is located further away from me where I sitting. since my ideal viewing experience is one that the monitor covers the entire peripheral vision of a person.
but a LCD TV and 24 inch LCD monitor that is running at 1080p (1920x1080 res) is still producing an image 2 million pixels
compare to a 27-30 LCD monitor thats runs at beyond FullHD like 2550x1600 or a image with 4million pixels.
which for me, is that only reason I prefer a 27 lcd monitor over 42 LCD TV

u2412hm is not available at any shops i think, can only buy thru Dell's website. I dun see enuff asus monitors so I cant comment on it yet

why dont u use ur laptop's external video connector for a 2nd extended monitor?
i did that and found out i used the extend monitor's desktop area more becuz 1) IPS panel 2) bigger surface area

hey, anybody has experience with their U2312HM flickering? Mine happens only if I'm using the display port while DVI doesn't have issue. What should I do with this monitor?
