So it looks like I've got 185Hz at 1920x1080!

ImageIt's a 144Hz monitor I bought through e-bay, I'll try to find a model.

Edit: It's called the X-star DP2414LED.

Haha, nice work man! 185hz seems like the go to for most people, have you tried any higher?

240Hz or not worth it :mrgreen:

Only half kidding. 240Hz is the only refresh rate next to 120Hz that can accurately reproduce 24/30/60 FPS content.

That's why everyone needs adaptive sync ;)

I jumped to 200 after 180 because I'd gone up in small increments up to that point and was beginning to think that I'd stumbled upon some miracle monitor (I didn't expect much considering it's a monitor I'd bought for £120) but at that point the screen went black and flickery. Dropped it down to 190 and shit was still weird and blurry. Dropped down another 5 and decided to leave it there for now. :D

The thing is, all of the content I watch (except youtube of course) is with SVP (Smooth Video Project) which interpolates video to a higher framerate so perfect scaling isn't an issue to me 8-)

Now you need overdrive at such high refresh rate :)

Pro tip:

I sometimes use SVP for youtube (for gaming footage that's only 30FPS.) Works fine. (Through SMplayer with MPV backend. I'm on Linux though.) You just drag&drop the video link from youtube into smplayer and watch it.

I think VRR / G-sync / Freesync is a great innovation but I think eventually people might realize that dynamic frame reprojection might be better, even for non-VR games.

Hmm, curious why you would say this. With 24p and no frame interpolation, all you need is 3:3, 4:4, 5:5 pulldown and you're done. Perfect 1:1 repro of 24p due to integral multiples of the (fixed) source framerate.

If you want BFI then you need 2X integer multiples avoid interpolation, so, 4:4, 6:6, 8:8. Or, in other words, 48hz x 2 = 96hz, 72hz x 2 = 144hz. 60hz / 120hz won't work, obviously, but 120hz does work as you say because it's 5x 24. 120hz is indeed a "magic number" which is widely compatible with 24 / 30 / 60hz native content, as is 240hz / 480hz / 960hz.

To me the big ones are 24p and 60p, and I use FI instead of straight up frame repeating aka 1:1 pulldown ratios.

Have you tried Dmitri Render? It hasn't been updated since 2015 but to me it looks way better than SVP, hardly any haloing artifacts which I find extremely irritating in SVP. I wonder if D.R. just gives up if the motion vectors are too complex and just says "eff it", like some TVs do. I watched Rogue One on D.R. last night, best space fight scenes EVER! And D.R. looks insanely good on my G-sync monitor too, at 144hz. My projector lamp died so I've been having to watch more on my G-sync lately. Man, D.R. is good. Way better even than my PJ at 72hz / 75hz.

I haven't done too much research about 75hz over 72hz (or 71.928 rather) mode on my projector in terms of final interpolated image quality, so I'm wondering if indeed 75hz not being a multiple of 24hz is a good thing or a bad thing. Do I want most frames to be interpolated? Or do I prefer to have 1/3rd of them be straight-passthroughs. This engenders questions about 24p source frame motion blur, is it better to apply de-blurring (which will introduce some artifacts but sharpen up frames) prior to any FI filters or leave it alone.
