The ThinkPad T490s also retains the 14.0" FHD (1920 x 1080, 250 nits) IPS panel. In addition to the brightness of only 250 nits, the NTSC color gamut is only 45%. In the past, the screen was complained by users that the color is not accurate. The factory finally beginning to enhance the color gamut of the screen, even Full HD panels can provide 72% NTSC color gamut (close to 100% sRGB color gamut coverage). If you are a professional, you can even choose to support the wide color gamut WQHD IPS screen.
The ThinkPad T490s follow the X1 Carbon 6th in terms of specifications, such as canceling the independent display chip, canceling the memory expansion slot, canceling the RJ45 network connector, adding the WQHD HDR wide color gamut screen. Therefore, many users are quite dumbfounding when they see the T490s specification. Last year's T480s started with a weight of 1.32 kg. This year's T490s had a starting weight of 1.27 kg. The larger difference in appearance is still in the thickness, from 18.45mm to 16.1mm, which is even thinner than X390.
Like the ThinkPad X390, the T490s are available in 8GB, 16GB or even 32GB DDR4-2400 memory. Due to soldering on the motherboard, it is not possible to expand the capacity.
