Embodiments described herein provide various examples of displaying an endoscope video of an endoscope resolution on a display having a screen resolution lower than the endoscope resolution. In one aspect, a process of displaying the endoscope video on the display can begin by displaying a portion of the endoscope video having the same resolution as the screen resolution on the display. While displaying the portion of the endoscope video, the process detects a surgical tool present in an off-screen portion of the endoscope video not visible on the display, and therefore not visible to the user. The process further analyzes the off-screen portion of the endoscope video including the detected surgical tool. The process subsequently generates an alert when a risk of the detected surgical tool is identified.
