LC-Power has only been making gaming monitors since 2019 and the company launched its first OLED offerings earlier this year. Today we're assessing the 27in model, utilising the same 4K/240Hz Samsung QD-OLED panel as MSI's 272URX and AOC's AG276UZD. It promises up to 1000 nits peak brightness, infinite contrast and near-instant response times, all at the attractive price of just £669 here in the UK. Let's find out if it's worth buying.

On the topic of pricing and availability, so far I've only found the LC-Power M27UO listed on Amazon, but the £669 asking price makes it £30 cheaper than both the AOC AG276UZD and MSI 272URX, though the latter appears to be a temporary deal and the £999 MSRP is significantly more expensive. Still, it goes to show just how competitive the OLED market has become, so let's take a look and see what the M27UO can bring to the party.
