Buying several 40" TVs for short term rental. Looking for the basic difference between these models. Thanks!
Based on just throwing those numbers into a web search, two are made by TCL and one is made by RCA. One of the TCLs is a "Class 3-series" and the other TCL is a "Class S-series". There may be differences in panel/display quality, refresh rate, ports, warranty, etc. It may be worth looking at some spec sheets and/or reviews if you really care. (Based on some places I've stayed – I don't think they did, so I'm guessing you're not that interested in the fact that one might have more HDMI ports than another, but I can only guess.)
Keep in mind that Roku doesn't make the TVs. They just provide the software and the software is pretty much the same on all of them. Most Roku TVs are of the cheap Chinese variety.
