Fantstics increase in the level of detail visible on screen following an upgrade from an HD monitor to a pair of 4K monitors.
I didn't want the higher spec'd LG models with speakers built in to the screen (as I have speakers and a soundbar) nor did I want screens with their own height adjustable stands (as mine were going to be fitted to a wall mounted dual arm monitor bracket). Online research showed all the panels I was looking at to be exactly the same anyway.....except for the UL850 which includes built in speakers.
Installation was easy and operation of the monitors couldn't be simpler.....but you do need to download software from LG's website which, again, is straightforward.
Really pleased with the screens......the only negative is that the supplied display port leads could do with being longer, not everyone's system box is within 1M of the screens.
