Questions about this item

Will the 300 cd/m² brightness hold steady during long work sessions?

The panel is rated at 300 cd/m² typical brightness; sustained output depends on the laptop’s backlight driver and thermal design, which are not part of this replacement screen.

Does the 60 Hz refresh rate generate noticeable heat or fan noise after hours of use?

The display itself draws minimal power at 60 Hz and has no active cooling; any heat or noise comes from the host laptop’s GPU and chassis, not from this 14‑inch 40‑pin panel.
