There is hardly any 120Hz TVs on the market but there are hundreds of 120hz 1440p monitors.
This is point. For the better than 1080p market, a 1440p monitor is a much more affordable option. Still not in the super cheap market but they are getting much closer. For people paying $500+ (depending no where you live) for a PS5, I feel many would also spring for a 1440p monitor. I did that and I really like the 1440p Dell monitor I have.
This is purely Sony's decision.
I feel you are 100% correct sadly.
Why support 720p but not 1440p as it's a full integer scale of that? 4x. Makes zero sense.
Also a quote from the article shared above.
The PlayStation 5 currently does not support 1440p resolution because Sony wants to "prioritise support for TVs".
To me this is an excuse which in reality means, we mismanaged our design time and thus this feature didn't make the cut time wise
Or more likely its - We hope people also buy a Sony TV to play their PS5 on.
It looks like Sony cut a feature to help boost their own brand on TV sales.
Considering how easy it is to add in 1440p when you already have 720p and 4k is just not on. Can't give Sony a pass on this one. Sony get an F for this.
