Please don't vote cold if you don't understand what this monitor is. Instead, see if you can find a comparable one cheaper in the UK.
This monitor uses the same LG IPS panel as a 27" Apple Cinema display, and has a 2560 x 1440 resolution - still 16:9 but higher res than 'full HD' meaning more desktop space to use on your PC.
It has a 3 year RTB warranty with OcUK.
It Was initially available at this price for pre-order but has been 380 for most of the time since then, and is 400 from DGM themselves, with only 1 year warranty.
Your best alternatives (apart from Hazro, which is more money and not as good) are Dell Ultrasharps for over 500 quid, or imports from Korea. These can be as low as 200 pounds BUT will then have import duty / VAT on top, do not come with useful warranties, and usually have a lot less functionality (no OSD, no scaling, no analogue inputs, Duallink DVI only, etc).
This is a very good deal for particular people, so I figured it was worth posting now that the price is temporarily down again.
For people who don't want higher res displays or think they can get the same thing on ebay for 150 quid, (and its 1080p, which is better, right?!) I welcome all of the usual ignorant comments below. Really, post away. But I'd simply request that you don't vote cold unless you genuinely know better, because doing so will keep this deal out of sight for the people who care about it.
