HP ZBook displays 

Our HP ZBook 15 G2 is crafted to maximize your productivity. With three different options we offer displays to suit any 
professional and cater to their needs. With a 15-inch diagonal screen size, there is a perfect display for you whether you 
travel a lot, or need more screen real estate at your desk. With our multiple resolution, viewing angle, and brightness 
options, you can choose the perfect display for your needs without breaking the bank. Whatever you are doing, or 
whatever your job demands, HP’s ZBook 15 G2 has you covered.

Choosing between these different screens boils down to what is important to you. What do you need to execute your 
tasks and do your job? Our 15-inch displays come with a 16:9 aspect ratio which allows you a comfortable workspace and 
keyboard layout. If you travel but also need the screen real estate and horsepower, the 15" diagonal HP ZBook display 
fits the bill. With a beautiful full HD panel this is the perfect middle ground for any professional. If you value resolution or 
need to be able to see details, a higher resolution display is going to be important, no matter what size; however, if you 
mainly use your computer for word processing and Excel, a lower resolution display is a great way to save some money. 

HP ZDisplays 

While our HP ZBook displays offer so much, we know that you aren’t always going to be using them. Many of you will 
be using a docking station to connect to our HP ZDisplays at your desk or office. HP ZDisplays offer great expandability 
to the HP ZBook. With sizes ranging from 22" to 30" diagonal displays you can find the perfect size for your work. HP 
ZDisplays offer the same great resolution, brightness, viewing angles, and quality of the HP ZBook display. However, 
our HP ZDisplays let you work on a much larger screen and even with multiple monitors at once allowing you to be as 
productive as possible.

HP DreamColor 

Hewlett Packard offers high-quality displays with our DreamColor technology in both our HP ZBooks and HP ZDisplays. 
These displays offer brilliant ten-bit color that drive 1.07 billion colors onscreen. Factory calibrated for high color 
accuracy and recalibrate-able with the DreamColor Calibration Solution or other professional measurement instruments 
(Z27x only), allows users to excel in areas including animation, visual effects, post production, digital photography, 
and digital pre-press. With 4k input support (Z27x only), HP ZDisplays offer high definition with beautiful color as well 
as accurate brightness adjustment using candelas per square meter instead of relative brightness measurements. A 
DreamColor display is a great addition on an HP ZBook or an HP ZDisplay. Both options carry the same specs and quality 
to keep your work perfect. If you put the two displays side by side, the colors will be identical. One of the many amazing 
reasons HP DreamColor is so great.
