Hi, and welcome to TSG.
The best solution to maximize resolution to get the most out of a 4KHD monitor is a computer with a video controller that can output 3,840 x 2,160 pixel 4KHD video. If you wish to stay with your current laptop, you should find out the maximum resolution you can get from the video output port for your desired mode or either mirroring or extending the desktop. Then purchase a monitor with that resolution. Upscaling can not add more pixels than what you have in the source. It just stretches what is given to fit the higher resolution of the monitor. That may be fine for viewing photos and videos but will result in fuzzy text in any kinds of text documents or spreadsheets.
