LG deliver the goods

[This review was collected as part of a promotion.] I've been so pleased with my new LG 45" oled ultrawide 880R monitor it's a huge upgrade from my Acer Predator monitor, this fits my rig perfectly and delivers great immersion for sim racing. I'm still getting over the great colours, and the blacks stand out so well. My only problem I found was getting my older titles to work with this wonderful monitor, but with some tweaking a happy compromise was found, I was also pleased to see a remote came with this monitor, so useful for sim racing.

The best gaming experience I've ever had.

I recently upgraded to the LG 39GX90SA-W and it completely changed my gaming setup. The OLED panel delivers incredible picture quality with deep blacks and vibrant colours, and the ultra-fast response time makes every movement feel incredibly smooth. The 240Hz refresh rate is a huge jump from my previous monitor and you can really feel the difference in fast-paced games. The 39-inch curved screen is extremely immersive and makes every session more enjoyable. Overall, this monitor exceeded my expectations and it's easily the best display I've ever used for gaming.
