Without knowing what laptop you have it is not a question I can answer. I can tell that laptop graphics are very customized to the model so I would check the specs for your laptop on it's makers site. It should list maximum resolution. Good luck!
Thanks for your response.
I am using HP Elitebook 850 laptop. The maximum resolution for the laptop listed in the specs is 1920x1080. It has a display port to connect to external screens.
Isn't the maximum usable resolution is dependent on the screen as well as the graphic card? For example, if I connect this laptop to an old screen (or an overhead projector) that supports only up to 1024x768, that is the maximum resolution I can use. So I was wondering that if I connect it to a higher resolution screen (say 4K) using the display port, will I be able to use higher resolution.
yes but many specs will give the external maximum resolution too.
What revision of the 850 there is G1 - G4?
If it is a G4 Maximum resolution is
Resolutions up to 4096 x 2304 at 60 Hz supported
G2 & G3
Supports resolutions up to 3840 x 2160 @ 60Hz
G1 is limited to
Thanks a lot. This helps.
I am using G3.
