The broadcast freeTV electronic program guide (EPG) on my current TV is trash. It’s clear they only cared about big corporate apps (that paid to get dedicated branded buttons on the remote).
Squint to see the tiny text (probably because it was designed & tested on a non-4K tv)
You have to visit the channels first for the EPG to populate for them.
There is no line to denote your current position in time on the chart. Instead you have to read the (tiny) time at the top right, then guesstimate its position on the chart, then look down.
My decade+ old Samsung plasma is so much better; but it wasn’t a “smart” tv, so broadcast TV was its tea.
(Of course this still doesn’t fix the fact the “apps” are buggy and slow. Already had the TV warrantied and parts replaced once because of some of them going black and white. I have no idea how such as weird problem could manifest OR how the solution was to exchange hardware components)
