If you have the budget and desire a large, ultrawide display, the Acer Predator X45 would serve well for immersive gaming and broad workspace for productivity tasks. However, its text clarity and pixel density aren't ideal for sharp, detailed work. Conversely, the Pixio PX277 OLED Max, while smaller and less expensive, offers better pixel density, which makes it good for both gaming and productivity, with sharper text and image clarity. Neither of these monitors is optimized for HDR content creation, but both provide a good experience for HDR gaming and media consumption due to their high contrast and color accuracy. Choose the Acer Predator if you prioritize a wide, enveloping display, and the Pixio if you want a balance between cost, size, and sharp visuals. Give Feedback
