[Closed] Zwift me up Scottie

I'm in the process of organising a smart turbo setup in garage for wife & self
turbos are bought & installed
plan to use iOS devices with wired connections to separate monitors for each of us
the tv will be 3-4' away from us
I was planning on 28" screens
If I use a couple of old-ish tvs of around this size , currently not being used-would I get a satisfactory picture with these[cheapies from Netto etc]
I've looked at new monitors with mentions of refresh rate & lag-
I don't want to spend a huge amount of money-maybe £150 per tv/monitor each
what would readers recommend please?
