Topic: How does interpolation work on 60hz panels as opposed to 120hz panels?

I have an LG TV that's 60hz, but it also comes with the interpolation (TruMotion) feature, so it doesn't kick in to 120hz past 60fps. Also, same with SVP I thought there was so much information on the web about how 120hz TVs were developed simply because the 24 frames couldn't fit properly into 60, meaning interpolation couldn't work unless the framerate was divisible with the number of that of the refresh rate? Now TV manufacturers found a way to somehow implement interpolation with 60hz panels. Take a look:

Especially with SVP, how does it take almost any framerate and convert it into 60+ fps?

I would say this is simply the benefit of a software-based method rather than a hardware-based one - it is more flexible in what it can do such as handling virtually any framerate.

Re: How does interpolation work on 60hz panels as opposed to 120hz panels?

I have a more general question, anyone with experience can let me know.

If I go from a 60Hz monitor running SVP @ 60FPS to a 144Hz monitor running SVP @ 96FPS (for source = 24), 100FPS (for source = 25), and 120FPS (for source = 30fps)... How big of a difference, if any, is there going to be? (I know there's a massive difference in gaming, I've seen it, and cannot un-see it).

If anyone is using SVP @ really high frame-rates (4x Source) using a 144Hz gaming monitor with motion-blur reduction (strobing) or without, and can comment on this, it would be great.

Using 4x Source at 60Hz gives me a more fluid experience than setting SVP to monitor refresh rate already, so I wonder how it would be like without ANY frames dropped because the monitor refresh rate is > FPS when using a 144Hz monitor.

Well, what refresh rate are you running these interpolated videos at?

You will also get the best result if you interpolate by a non-fractional ratio (2x, 3x, 4x, etc), and then have your monitor's refresh rate match the interpolated framerate.

Also, at least for interpolated video, I find that past 90-100fps doesn't make much difference really - you get a smoother result by "cranking up" SVP's settings past the default (such as using "Uniform" and "Complicated", though the latter causes some more noticeable artifacting...)



Oh and BTW, if you have a 144hz monitor, see if it's lightboost compatible so that you can enable backlight strobing - this will improve the motion resolution, but isn't available above 120hz:
