Get the LG 27GP850 for £200 with code HAVE20 (refurbished, was £250)

The seller has a feedback rating of 99.8% positive, and promises ‘fully working’ models with the original box, cables and accessories, just sans serial numbers - so you likely won’t be able to make warranty claims, which is a challenge with used items anyway. Returns are accepted within 14 days, which is nice to see too. Regardless of whether you’re looking at new or refurb models, the 27GP850 and its predecessors remain competitive with the best gaming monitors. I think these models really hit the current price/performance sweet spot: 27 inches, 2560x1440, 180Hz, FreeSync/G-Sync Compatible. You get a comfortable size, high enough resolution to look good at that size without being too hard for your GPU to drive, high refresh rate support for competitive gaming, and FreeSync or G-Sync to smooth out uneven frame-rates and reduce judder. The only thing that’s really missing is great HDR, with these displays’ DisplayHDR 400 rating denoting that they can accept an HDR signal and display expanded colours, but don’t get bright even to deliver super-impactful HDR. Still, you wouldn’t expect a great HDR experience even for twice the price, so I don’t think this is a massive issue. All in all, I’m stunned to see such a good monitor at such a low price, and even at the £299 that Currys are asking right now, I think you’re getting a great deal.
