Just when you thought they were as good as you could get, the big tech CES show in Las Vegas proved that there was still room for improvement. Laptops have just got speedier, with swivel screens, dual screens, 3D, modular technology and OLED image quality all now on offer. Lenovo offers such display flexibility in its ThinkBook Plus Twist, ThinkPad 16p Gen 4 and Yoga Book 9i, respectively. Asus ProArt Studiobook goes 3D without the need for glasses, even for movies. There are also juicy innovations for Gaming PCs, with the HDR miniLED panel of the ROG Zephyrus G14 or the ROG Strix with 18-inch panels, HDR technology and a 240 Hz refresh rate.
