The big question is, of course, what's the LG 84LM960V like with Ultra HD (4K) content? Helpfully, we employed a media server with bespoke content to see the screen strut its UHD stuff.

The panel's ability to depict even tiny detail is quite amazing. The window-like clarity that Ultra HD affords is spellbinding.

The good news is that the screen does a rather fine job with Full HD too. The most obvious characteristic of up-conversion is smoothness; it's like watching low ISO 35mm film stock.

LG 84LM960V review

Even when movies and TV shows are viewed up close on this massive panel, there's no image deterioration at all. Colours are highly saturated, blacks deep and textures virtually tangible.

LG hasn't actually released any information about the chip solution used to upscale Full HD to Ultra HD. Does the picture processor remap to the denser pixel grid using a database of image information to help interpolate images? Can it exploit legacy high frequency information in the incoming signal? LG isn't saying.

The resident HD Resolution upscaler does appear to be a multi-chip solution, though, not least because of a micro-second delay involved in delivering content to the screen. The biggest casualty of this lag is video gaming.

LG 84LM960V review

The delay between trigger and action will hobble serious players. This is crying shame, since visually, HD games look brilliant on this big screen. The fine detail and dynamics of Battlefield 3 are simply mesmerising, and when you take to the skies, there's a strong chance you'll suffer motion sickness.

The set's 3D performance is also a revelation. Unlike vanilla-flavoured 1080p FPR screens, there's enough pixel power available here to maintain Full HD resolution even through polarised glasses, and there's precious few crosstalk effects when viewed head-on.
