The issue has been raised about the frequent inserting and pulling out of the HDMI cord on the Chromebook causing software issues.
The way I have it set up in my exam room, I think reduces the likelihood of an electrostatic discharge. The TV is plugged in and often times is off, as it turns off automatically after several minutes. The Chromebook is powered by the battery, and I do have the Chromebook on when I hook up the HDMI cable into the Chromebook.
I think the wear and tear issue is potentially more problematic, and will be getting the HDMI extender (as indicated above) so will hope to have some feedback on this issue more in the future. But a 5 dollar extender is easier to replace than an HDMI port in the Chromebook.
I think the unknown is how often or problematic the potential(?)software issue on the Chromebook or TV will present itself, if ever.
However, I have no patient data on either device (Chromebook or TV), so both are quite cheap and easily replaceable, so minimal downtime if a problem develops.
I think it is a manageable risk at this point, otherwise powering off the Chromebook at each coupling would be impractical.
I maintain the advantage of projecting AC on the large screen TV in the exam room, far exceeds the risk. I am knocking on wood, but nearly 4 months into this set up and no issues yet.
