TVs are either 50/60hz or 100/120hz
50 and 100hz TVs are from PAL regions (like EU and JP), but they also support 60/120hz since at least the 90s, so if you have a 100hz tv, it can also run 120hz.
The new 40hz modes are only available on 120hz screens (and 100hz which are interchangeable). It shows the same image for 3 refreshed and then updates, which makes it run at an even pace (3 * 40 = 120).
A 50hz screen is the same as a 60hz screen, so the best framerate is either 60 or 30, since those will give you an even pace.
Interesting. If I was a manufacturer of a TV that could run at 120hz I would not market it as 100hz. I honestly believe some people will be choosing the 60hz LGs over 50hz Samsungs in my local store.
I assume the same is not true of computer monitors. My store has monitors advertised at 75hz, 100hz, 120hz, 144hz, 160hz, 165hz, 170hz, 175hz, 180hz, 240hz, 280hz, 310hz, 360hz, 480hz. If an extra 5hz matters enough to put on the specs, I do not image my 100hz monitor is going to miraculously run at 120hz if I connect a XSX and play a 60fps game. I'm guessing it would drop down to 60hz to avoid screen tearing, and I might be better of picking 40fps to get it up to 80hz.
And why does 144hz even exist??? It doesn't sound like 30fps, 40fps or 60fps games are going to get the most out of those monitors. 160hz (40x4) and 180hz (60x3 or 30x6) make more sense, although 240hz (30x8, 40x6, 60x4) seems the most future proofed should we start getting 120fps games.
You are correct that monitors and TV handles their frames differently. The tecnology is the same but the use case is different. Traditionally your monitor would support different preset hz modes it would switch between depending on the software (and in the CRT days the resolution). So if you run a game at 60hz a 100hz monitor would just run it at a 60hz refresh as well.
Traditionally many games would run at variable framerates on PC. Things have changed in the last 10-15 years, so locking the refresh rate (which is different than frame rate) is a standard feature now.
The odd number of hz on new monitors makes sense because they support VVR, where the refresh rate is dynamic and therefor doesnt have to split evenly like previously.
Screentearing happens if the game can't render a new frame fast enough, before it has to be shown on screen. As a result the game/console/computer just outputs the incomplete frame filled in with the previous frame (which produces a tear), and then starts rendering the next frame. So it's not directly related to hz.
I take it you are from EU since you are seeing 50hz TVs in your local area? And yes, picking a 60hz tv over a 50 one would be irrelevant.
