Answer
A Chromecast device plugged into the TV, paired with Google Chrome's built-in Cast functionality on a PC (casting the Aurena Lobby browser tab to the Chromecast), works well for this — one genuine benefit is that the TV itself just needs an HDMI input, so even older, non-'smart' TVs and monitors work fine as long as a Chromecast is plugged in, without needing any browser or smart capability on the TV itself.
