So thats a 2560x1440 IPS monitor with 120Hz refresh?

Sounds insane :D

And here I am stuck with lowly 60Hz Hazro...

That lowly Hazro has pixel overdrive and is designed to work at the same refresh rate as these Catleaps (which do not possess pixel overdrive). Again people have to calm down and realise that setting a monitor which the technoloy isn't ready for doesn't equate to fantastic responsiveness. It isn't that LG are missing a trick by not implementing 120Hz support on their IPS panels, it is that there are solid reasons for it not being there at the moment.
 
I picked up a mini DisplayPort to HDMI adapter for £4 recently, I haven't checked but I imagine a dual link DVI cable wouldn't be much more if not a similar price. Why then are these adapters so expensive?

Maybe there are licensing fees involved. I genuinely don't know, but it's extremely frustrating that I can't use one of these monitors for the same price that everyone else is paying.

Unless you go a very good deal, it sounds like you purchased a passive mini-DP to HDMI adapter (like this one). In many circumstances this will work fine (they can be cheap as they rely on the graphics card outputting what is effectively a DVI/HDMI signal over the DP connection - so it is only a simple pin-swapping adapter that is needed).

In contrast, active mini-DP to single-link DVI or HDMI adapters (which unlike a passive adapter actually convert a DP video signal into DVI) are much more expensive - here is one for £24.

In addition, for a dual-link DVI connection you need an active (not passive) adapter to support the high bandwidth signal and to achieve the much higher dual-link DVI bandwidth the adapter needs to be even more complicated than a single-link DVI one, thus adding to the cost.

The price of the DP to dual-link DVI active adapters is rather high, but DP to single link DVI/HDMI active adapters were a similar price a few years ago - since there wasn't much demand. However, recently the demand for these single-link adapters has grown massively (as many more people have graphics cards with DP output and eyefinity can be achieved relatively cheaply with 1080p/1200p 60Hz monitors), therefore many more companies now sell them and prices have tumbled. Hopefully, something similar will happen to the DP to Dual-link DVI adapters as high resolution (and 120Hz) monitors and graphics cards with a DP output seem to becoming increasingly common.

It's more than that. I don't know exactly what is required but display port to dual link DVI is not pin compatible; the adaptors require power and are 'active'. They are manipulating the signal in some way and as such that is why they are expensive.

If your display port is a displayport++ you can get away with a passive adaptor but I have literally no idea how you can tell that.

Thanks :) I've never even heard of DisplayPort++ until now. Can't they just keep these things simple?!

EDIT: One of the reviews on this page states that the passive adapter does work with the Dell XPS 17 (L702x) which is the laptop I have. Interesting...

That means you can use a single-link DVI or HDMI monitor with that adapter/laptop, however - to run a high resolution monitor (like one of these 2560x1440@60Hz ones) you will need a dual-link DVI connection. So in that case one of the £75 active DP to dual-link DVI adapters would be required.

This makes a lot of sense, thanks.

I may be tempted to splash out on a DVI adapter if I use my monitor with my MacBook often enough. For occasional use 1080 should be fine.

The fact that 1440p and greater monitors are so few and far between in 2012 kinda annoys me. The new iPad has a greater resolution than the majority of monitors on the market right now... just why?!

At work I use a 1080 24" monitor (mainly CAD), 1440 would be very useful but I don't have that option. But to browse the web on the sofa and play with a few apps you can get better than 1080 (can't remember the exact res) on a 10" screen.

Rant over, I just love the retina displays, I want one for my PC :(
 
At customs with missing invoice does not inspire confidence. You will probably have to produce paperwork to demonstrate what you paid i.e. your credit card bill, ouch.

I wonder how may of these will ship to the UK before customs start paying attention?

I thought it was too good to be true :( Hopefully one of these manufacturers brings out a model with more connectivity options.
 
On a side note does anyone have a clue or read anything about the availability of these monitors on an ongoing basis? The reason I ask is that I am planning a long overdue upgrade but trying to hold off to see what ivy bridge brings both in terms of performance (I know it's going to be minimal) but also perhaps slightly driving down prices of sandy bridge components (again minimal).

Also hanging off on which GPU to buy but I think that given my budget in that area of around £200 it's really got to be a 7850, plus I'm not into all this needing to play at super ultra **** settings and them moaning about a few FPS here and there (plus my eyesight is so **** I can barely notice anyway and I virtually never notice input lag either).

So I'm thinking do I jump on this while they are still readily available and cheap as they may be a limited run coming out of South Korea, or do you think they will be available on an ongoing basis and I could hold off a few weeks to make my mind up? I know it's a guess but you never know someone may have half a clue unlike me :)
