FreeSync worked well on our RX 580 in Deus Ex: Mankind Di­vided

LG’s 34UC79G-B is a curved 34in widescreen unit that sup­ports FreeSync at 144Hz, so we were sur­prised that it costs just £480, se­ri­ously un­der­cut­ting many other curved pan­els on the mar­ket. The big­gest rea­son for the af­ford­able price is the 2,560 x 1,080 res­o­lu­tion. That’s lower than many other large, curved screens and it means in­di­vid­ual pix­els can be seen up-close, but it’s not all bad, as the lesser pixel count means it’s eas­ier to get this screen run­ning with mid-range graphics cards.

It also makes it eas­ier to achieve smooth frame rates with FreeSync, which func­tions at a min­i­mum of 50fps and a huge peak of 144fps. It worked well on our Radeon RX 580 test card in Deus Ex: Mankind Di­vided and The Witcher 3, pro­vid­ing tear-free game­play at solid speeds. The curved, wide de­sign is great for im­mer­sive gam­ing – in many sce­nar­ios, it’s bet­ter than a stan­dard 4K panel, which will have re­duced width and extra height. The wider field of view pro­vides more im­mer­sion in rac­ing ti­tles and more room to ma­noeu­vre in FPS games, and it serves up more use­ful screen real es­tate in strat­egy and MOBA ti­tles.

The LG uses an IPS panel, which usu­ally means solid colour ac­cu­racy, and it’s se­cured in­side a de­sign that mixes matt black ma­te­rial with red ac­cents. The stand is sturdy and easy to as­sem­ble, and it of­fers 120mm of height ad­just­ment. It can’t tilt, swivel or ro­tate, but that’s nor­mal for more cum­ber­some widescreen dis­plays. Mean­while, the on-screen dis­play (OSD) takes up the right of the screen and is con­trolled by a joy­stick. There’s a quick menu for com­mon set­tings such as bright­ness, contrast and vol­ume, with more in-depth op­tions in the full-fat menu. It’s quick and easy to nav­i­gate, even if the joy­stick is a lit­tle wob­bly.

In terms of per­for­mance, the LG’s fac­tory bright­ness level of 259cd/m2 is fine, and the black level of 0.19cd/m2 is ex­cel­lent – enough to de­liver deep black shades. Those fig­ures com­bine for a contrast ra­tio of 1,363:1, which is bet­ter than many gam­ing mon­i­tors, mean­ing colours are well de­fined across the en­tire range. Those colours are ac­cu­rate, too. The delta E of 2.28 is good, and the 6,501K tem­per­a­ture is fan­tas­tic. It all means colours will ap­pear as the de­vel­oper in­tended, and the LG can pro­duce 92.1 per cent of the sRGB gamut.

With a re­duced bright­ness level of 150cd/m2, the LG con­tin­ued to per­form well. Contrast and colour tem­per­a­ture re­mained solid, and the delta E im­proved to 0.74. The LG’s wide de­sign didn’t cause uni­for­mity is­sues either. The bright­ness varied by less than 12 per cent, even in the cor­ners, and colours only de­vi­ated by around 5 per cent. It’s a rapid panel too. It doesn’t have the su­per-low re­sponse times of TN pan­els, but its av­er­age re­sponse time of 10.3ms is still eas­ily fast enough for gam­ing.

Ig­nore the pre-con­fig­ured gam­ing modes though. The first FPS mode’s colour tem­per­a­ture of 7,286K is too chilly and robs colours of vi­brancy, and the sec­ond FPS op­tion drops the contrast to an un­der­whelm­ing 586:1. Mean­while, the RTS op­tion makes the contrast and colour tem­per­a­ture a lit­tle worse than the fac­tory set­tings.


The LG 34UC79G-B’s fac­tory set­tings are fan­tas­tic, whether the screen is at full bright­ness or a more con­ven­tional level. It has good uni­for­mity, the gen­tle curve wraps around the user and AMD FreeSync works well, even at very high frame rates. The res­o­lu­tion makes pix­els a lit­tle chunky on the large dis­play, and there aren’t any speak­ers, but the LG 34UC79G-B is oth­er­wise a solid curved, ul­tra­w­ide FreeSync gam­ing screen, de­liv­er­ing good core per­for­mance on AMD’s cur­rent GPUs, while sig­nif­i­cantly un­der­cut­ting the high-res­o­lu­tion com­pe­ti­tion.
