PC monitor refresh rate vs TV refresh rate

[jurisc]

Hi, I was wondering, why does PC monitors are limited to only 144hz while TV's can sport much higher refresh rates - i've heard about 800hz, 1000hz panels etc.

Most HDTV's are only 60hz, even if they say its higher. The "higher" refresh rates are due to Frame Interpolation which in short, makes fake frames to give the appearance of faster refresh rates. But comparing a HDTV with a 240 refresh rate to a monitor that supports 144 FPS would be a huge difference as the monitor frames would be much clearer. If your considering using a HDTV for a monitor just go for the cheaper model (120 vs 240+) as your only going to be utilizing the 60 FPS. On my Samsung HDTV I actually disable the 240hz "gaming mode" and keep it at 60 FPS since personally I think it looks better and 60 FPS is plenty for my gaming.

thanks for answer WildCard99, i've noticed in the wikipedia post that there exist some 240hz native TVs - so why are PC displays limited to 144hz then?

You can't really compare a HDTV at a really high refresh rate to a monitor that is at 144hz. The monitor that's using 144hz will actually be using 144 FPS (noting that the PC is powerful enough) while a HDTV that is 240hz(+) is really only utilizing 60FPS (or less depending on content) while inserting "fake frames" to give the appearance similar to the monitor. But if you have ever seen a HDTV running @240hz compared to a monitor running at 144hz the difference is noticeable. I'm not sure why monitors are limited to 144hz but I can imagine its either (1) the tech isn't there to push faster frame rate (2) there might be a limit to how much the eyes can process these high frame rates and maybe going higher wont have a huge effect?

Not true, there has been 240 Hz native TV's on the market since 2010, no interpolation. The fact that they only accept a 60 Hz input is true, but that doesn't mean that they interpolate to reach those numbers. Interpolation is a setting, and can be turned off, if turned off, what it'll do is repeat frames. If everything above 60 Hz in a TV was interpoiating, then there would be no 24p mode, and there would be no 3D. The only benefit using a 240 Hz TV vs a 120 Hz TV, is when you display Active shutter 3D content, and you also benefit from the faster pixel times, so less ghosting in 2D. The 240 Hz was required in order to completely remove the noticeable flicker and noticeable ghosting. This is why a 120 Hz Active 3D TV, often look equal or worse than a Passive 3D TV at 120 Hz.
