Well as for subject you have only owned Lenovo monitor as for you it's horrible I understand that but you said you bought a Huawei Mate book X and now you're saying Lenovo is bad it's about maximizing profit you have to use a Yoga, MIIX, Legion, ideapad, Thinkpad Series and then compare to Matebook ,
Next time when commenting first understand what you are typing then express you idea but Lenovo Makes many things if you're looking for a decent monitor you should have considered ViewSonic,LG, Samsung,BenQ, MI etc....
When buying first prioritize the need and purpose then check review and buy so it's your fault
And as I know Lenovo doesn't make LCD,LED,IPS,OLED panels
