Like many people in this pandemic my wife is working from home. She works on a Dell Inspiron 3250 with a 23" screen connected to the HDMI port. She does project management and works with large complex information flow charts. Her current screen size is not up to the task. I'd like to upgrade her to a larger screen and perhaps one with higher resolution or an ultrawide screen. After scrubbing the Dell website I can find all kinds of technical information on the Inspiron 3250 but absolutely nothing that specifically calls out the available screen resolutions for this model. Any help would be appreciated as to how to locate this information. Thanks in advance! Dan
