Unveiled at CES 2025, the Dell 32 Plus 4K QD-OLED monitor uses an infrared sensor to track the user’s head position and uses an artificial intelligence algorithm to adjust the sound produced by five 5-watt speakers.

By sending a sound signal to one ear, the monitor blocks this signal for the other: a similar wave is created in antiphase, and they neutralize each other. This is called destructive interference, a technology used in active noise-canceling headphones. Dell isn’t the first manufacturer to tailor sound to the user’s head position; a similar solution was used in the Razer Leviathan soundbar and last year’s Acer 3D monitor.
The Dell monitor seems like an interesting option for gaming. There is a 32-inch OLED display with 4K resolution and a 120Hz refresh rate. The screen boasts a response time of 0.3 ms; AMD FreeSync Premium technology is supported. The recommended price for the Dell 32 Plus 4K QD-OLED is a relatively modest $799.99 for a product of this level; in China it will go on sale on March 27, and in all other countries of the world it will appear only on May 22.
