I have a computer connected to a 27" monitor & a STB connected to a 23" monitor. I'm thinking about replacing both TVs with a bigger TV with 2 HDMI ports. I was browsing around the Best Buy website & saw a 34" 21:9 monitor.
Does the FIOS STB or the new TV One support 21:9? HMMM, I'm not even sure that my 2018 Mac mini supports 21:9! I'll have to ask Apple! Anyway, if FIOS doesn't support 21:9 there would be black bars on both sides of the 21:9 screen.
