Hi, i just got my yoga C740 15". The build quality is premium.
My daily basic work with adobe + microsoft office , no lag issue, fan is extremely quiet compare to my old Ideapad. The 500 nits screen is too bright, basic usage 50% is good enough.

The downside is screen colour is slightly yellowish. Even my old ideapad 300 no such issue

Do anyone know where to get services to calibrate screen colour, without buying spyder5 ?
