Hi Forum, I am currently using an HP zbook laptop and want to use a 27” 4K monitor with it. What can I expect from this setup? The laptop isn’t 4K. Is this a bad way to go?
I am currently sharing work visually among colleagues and thought if would be nice to see things a bit bigger. Also, to work from as a lot bigger for aging eyes.
Thank you, for any advice on this. Mark
It is the best way to go! I have 5-year old ThinkPad W530 laptop (15,6 inch diagonal size LCD, 1920x1080 resolution) and Dell U2718Q monitor (diagonal size = 27 inch = 68.47 cm, 3840x2160 resolution = 4K = UHD). The monitor is almost perfect; its only flaw is that its stand is about 10 cm too short. (I put the short stand on top of wider stand.) Configuration of the monitor for the Windows 10 operating system was challenging. My 5-year old laptop is powerful enough for the 4K monitor, except for some 4K videos.
I am 65 years old, so I have the same problem.

Put the monitor on top of a bunch of linux books or a flipped plastic box like I did with my Dell monitor.
DELL monitor’s simply doesn’t reach up to my level:

Thanks for the insight Andrew.—-Mark
Make sure the display adapter has enough capability and resource to drive an external monster monitor.
I would expect a “book” laptop to have a very minimal display adapter that has reduced capabilities to make it more energy efficient.
IMO: Then 4k on a 27" will strain your eyes more than a 24" FullHD.
Either go for 32" or go down to a lower UHD (2560x1440p) if 27" is your size limit.
Oh, and as John says, double check that your laptop can even run 4K over it’s display port. It might be limited to 1440p.
Good luck!
unless he sets the scaling in windows to 200%, which would be equivalent to FullHD (1920x1080)

I would appreciate a fix to the tiny manipulator and arrow display on 4k laptop (dell precision 7520).
Instead of piggybacking onto this message, please post a new message with an accurate description.
When you do, a screenshot would be helpful as well as the results of running the SystemInfo command.
With those details and specifics, we should better understand the problem.
Thanks
