2016-05-15, 8:47 AM

HI.

 

1) Does anybody knows, wich of these screens definitely not use PWM to control brightness?

 

00HN873 N AUO 14.0 FHD IPS AG
00HN874 N AUO 14.0 FHD IPS AG
00HN877 N LGD 14.0 WQHD IPS AG
00HN878 N Panasonic 14.0 WQHD IPS AG

 

i think the last one use pwm. Especially want to know if 00HN877 N LGD 14.0 WQHD IPS AG hase or not, and the other question, how can i ensure what screen in the notebook when buy it? can i understand it if i know part number?

 

or may be someone knows what model i will get if order through the lenovno site?

 

2) is the warranty worldwide? and if i extend warranty, it is also worldwide? same rules?
