HUAWEI reserves the right to make real-time modifications to the prior specifications to ensure they correspond accurately with the actual product's performance, specifications, indices, and components.
It is not necessary. Here is an example for you. Yes, yes. The laptop is more than 10 years old, the screen was produced in 2011, but years later even it was "reference". And here is the screen from Chi Mei. So the issue is not with the manufacturer of the screens, but with what quality the laptop manufacturer puts the screen.
BOE - good AU Optronics - OK Innolux (ChiMei) - Very bad
Avoid these laptops like the plague. It's a good thing you can only find Matebook D 15 (AUO screen) almost everywhere while sighting of Matebook D 14 (ChiMei screen) is rare... Matebook D is the cheap/budget lineup from Huawei meaning it's the Huawei bottom of the pile crap no sane person should be buying.
The 14-inch laptop from Huawei includes a Tiger Lake processor, brings an elegant metal case, produces only little noise, and offers a long battery life. At the time of our test, the whole package is available starting from 600 Euros (~$652).
