The cause for this appears to be the generic PNP monitor driver used for the 4k UHD display, which obviously fails in determining the screens size, while the external monitor is properly recognized as the exact Samsung type, surely telling its physical size.ĭoes anyone here know, how to get another (correct) display driver to be used for the internal display? Lenovo seems not to deliver one and relies upon the generic Windows driver (pnp monitor) which can not know and mybe also cannot get the size of the internal monitor. the Mouse pointer is forced to somewhere in the middle on the internal screen when trying to move it to the (larger) external one. When arranging the two screens in Windows 10, the large external screen apear as half the size of the small UHD display with in the beginning funny effects, but tending to really get on my nerves now. Now as a second external Monitor I use a FullHD screen, which is physically a good deal larger than the small notebook display, BUT: Hi have an internal UHD display in my Lenovo 920, which is a ohysically rather small screen, but has a 4k resolution. Now you: what is your monitor's resolution? I think that the advantages outweigh the issues but it depends on the programs that you run and how they display on a 4K or high DPI display. Scaling performed by' and set it to System.ĤK displays improve productivity for the most part but if you run them on Windows, chance is quite high that you will run into display issues with certain programs (unless you only run UWP apps and native apps). Check the High DPI Scaling Override option 'Override High DPI scaling behavior.Set 'Use this setting to fix scaling problems for this program instead of the one in Settings' to 'when I open this program'.There you switch to the compatibility tab and activate the 'change high DPI settings' button there to open the DPI options. You simply right-click on the program executable and select properties from the context menu. One recourse for the latter problem may be to disable display scaling on high DPI settings. Programs like DPI Fix were created to address the issue. Microsoft has a support page up on its website that highlights Windows scaling issues. If you run Windows 10 on multiple displays, like I have to test this, you may notice blurry text, elements that look out of size, or elements that look fuzzy.

Popular applications like PeaZip were updated only recently while others, like the new Malwarebytes 4.0, still may have high DPI issues.īut tiny text and interface elements is just part of the problem. Even programs that are still in active development may not support high DPI perfectly.
