If you're on a budget and mainly use your monitor for everyday tasks like browsing and office work, the Dell monitor is an economical pick that offers decent image quality and resolution. However, if you're willing to invest more for an immersive gaming experience with high refresh rates and superior contrast, the LG monitor will deliver significantly better performance. The LG's OLED technology provides deeper blacks and vibrant colors, making it a better choice for HDR gaming and media consumption, but keep in mind that it might not be as good for tasks where color accuracy in photo editing is crucial.

Phil Hayton | August 2023
"The LG UltraGear 45GR95QE-B is a brilliant ultrawide gaming monitor that'll dominate your desk, and its 800R curve serves to trick the senses. It's ridiculously pricey, and 4K fans may notice the difference with this 4K panel, but its OLED capabilities and arsenal of features almost justify its price tag. Just make sure you've got decent PC specs and plenty of space for this brute before parting with any cash."
