has also found that Intel’s integrated graphics can struggle with 4K
displays, making otherwise nice laptops like the Dell
15 7000 exhibit jumpy scrolling and choppy animations.
In terms of advertised battery
life, Lenovo’s Yoga
C940 14 promises 15 hours with a 1080p
display, and just 10 hours with 4K.
In short, 4K
TV marketing has blinded laptop shoppers to the benefits of 1440p
displays, so display manufacturers and laptop makers seldom bother to produce them.
Buy a laptop with a 4K
display, and you’ll get a picture so sharp that individual pixels become indiscernible, but both battery
life and performance will suffer as a result.
“While demand for QHD
displays is relatively low, there is a niche group of consumers we’re seeing with interest in QHD
laptop panels because of better power consumption and lower pricing as compared to 4K
laptops,” Peana said.
