Problem with the screen resolution 4k

when i install parrot os and upgrade it and install nvidia driver i get { window title is tiny and panal is margin very far between (network & battry … )}

What driver specifically? It is advised by Debian to use the Opensource drivers not the proprietary ones as they tend to change regularly?

Also what distro version you are using how you installed it so forth. Lay it out on the template and also attached screenshots would help.



i installed driver from
(LENOVO_MT_20378_BU_idea_FM_Lenovo Y50-70
Intel® Core™ i7-4720HQ CPU @ 2.60GHz × 8
Nvidia GeForce GTX 960M
