Why can a 60hz TV display a video at 120FPS but can’t display a game at 120FPS?
In: Technology
From the above answers, I’d give my statement as
Everything you see in these features of products like 90hz, 120hz , 240hz touch sampling rates ( ofcourse In mobiles ) they all come under sort of Marketing strategy..
Watch reviews of your wishlist products and then take a look onto those..
Those 120hz tv they sold you back in the day were actually 60 with fake frames in between. You can technically display a 120fos game on a 60hz TV we do it all the time on PC when we turn off vsync you are stil seeing 60 but the display will get 120+ and just update whenever ie tearing. Consoles just don’t have the option to just output at whatever fps they could if wanted to
It cannot. At least not truely.
If the display only updates 60 times per second (60Hz) it didn’t matter if you throw 9000 frames per second at it, all the other frames just won’t be shown.
There are some displays that can trick you into thinking it’s higher refresh rate, but that’s just guess work adding artificial frames between the “real” frames.
In short, a 60Hz display will only ever display 60 Hz worgh of “real” frames

It can’t, on both accounts. If a video shows 120 frames per second and the display only operates at 60Hz then only every other frame will be shown.
The advertised frame rate of a TV doesn’t have to match the maximum ***input*** frame rate it can use.
Eg a TV might advertise it’s 240Hz but it can only recognise and use an input signal upto 60Hz.
It can use the higher refresh rate to
* add extra interpolated (made up, guessed) frames
* reduce ghosting (where the pixels do not react as quick as is preferable). It can turn the back light on and off so fast it’s imperceptible but it’s off during the time a pixel is changing colours.
More modern “gaming TVs” can display, say, 120Hz and accept 120Hz input signals.
Edit.
Before August 2005, when HDMI 1.2 was released, HDMI supported at most, 60Hz input. HDMI 1.2 allowed 120Hz at 720p.
1080p @ 120Hz is enabled by HDMI 1.3 in June of ’06
