Could you summarise all of the top reviews for the Alienware AW3423DW for me?
The Dell Alienware AW3423DW is a QD-OLED monitor that combines OLED and quantum dot displays to produce perfect black levels with a wider range of colors. It has a 34-inch screen with a 21:9 aspect ratio, wide viewing angles, and incredible motion handling. It's excellent for gaming because of its high refresh rate with variable refresh rate support, near-instantaneous response time, and low input lag. It's also fantastic for dark room gaming or watching movies in the dark due to the near-infinite contrast ratio and perfect black uniformity. The monitor is good for office use and content creators thanks to the large screen.
The monitor comes factory-calibrated with remarkable out-of-the-box accuracy and displays a wide range of colors in SDR and HDR. However, it performs worse in bright rooms because the black levels raise when there are lights on it. The Alienware AW3423DW is fantastic for HDR games due to its high HDR peak brightness that makes small highlights pop, but larger areas of bright colors are noticeably dimmer. The monitor has premium styling and build quality but comes at a high price point of $1,299.
Would it be a good monitor for doing photo editing on?
Depends on what are you intending to do with it. If you focus mainly on professional work there might be other models better suited and calibrated to photo editing. On the other hand if you want to play games and occasionaly edit a photo it may be a valid choice.
