I currently have the Dell U2720Q monitor, which supports 4K 3840×2160 60Hz. Which Dell notebook (with dedicated graphics card) would I be able to use with this monitor via USB Type-C connection for a 4K resolution 3840×2160 60Hz and also use the same USB Type-C connection to charge the notebook battery?

I have a Lenovo ThinkPad E490 notebook that has a USB Type-C connection which I connect to the Dell U2720Q monitor at a maximum resolution of 4K 3840×2160 60Hz and also charges the notebook battery via the same USB Type-C connection (single cable for external video and battery charging). But there are some mouse lags and the image is not so smooth. I believe that because this notebook has only integrated video card Intel UHD Graphics 620. However with a resolution setting of QHD / WQHD / 2K 2560x1440 60Hz there are no mouse lags occur and the image is normal on the monitor.
