Great for TV, gaming and university work

[This review was collected as part of a promotion.] Really pleased with this monitor. It's great for watching TV and gaming, but it's also really useful for my university work. I can have multiple windows open side by side, so I can research and write my essays without constantly switching between them. Very happy with it overall.

Best monitor I have ever had

[This review was collected as part of a promotion.] I have always had one or two smaller monitors on arms. Mainly so I could turn one vertical. I have wanted one wide screen monitor for quite a while and when LG bought this one out I was impressed. As most of my kit is also Apple hardware I compared it with the 5g2g studio and decided this was the one to go for, well done LG.

Absolute killer

[This review was collected as part of a promotion.] I'm an avid gamer and graphic designer, and I have been waiting for this model since the announcement. Did not disappoint. Text clarity is finally acceptable, HDR is mint, and I was pretty lucky with the panel lottery, as there's only minimal grey banding, which I hope will slightly diminish with panel usage. Also, as of now, zero dead pixels. Considering its size and the resolution, I think it will become my personal favourite. 5K2K on a 39-inch ultrawide display might be the best invention since butter. Slightly oversaturated reds out of the box, but nothing you can't adjust to your preference. Gaming on this beast is a pure thrill. Highly recommended.
