If you're looking for an immersive ultrawide monitor suitable for HDR gaming with great color depth and perform well in dark room viewing, the Acer Predator X45 is a solid choice. However, its larger screen and lower pixels per inch might not be the best for detailed photo editing. On the other hand, the LG 27EP950, while more expensive, offers better image clarity, higher resolution, and higher pixels per inch, which is excellent for digital and print photo editing but has a lower refresh rate that's not ideal for competitive gaming. Both have OLED panels with deep blacks and infinite contrast. Give Feedback
