madvr 25 as 24 checked, reclock slowdown checked = 24 at 50hz, bad madvr checked, reclock unchecked = 25 at 50hz, good but expect 24 at 48 madvr unchecked, reclock checked = 24 at 50hz, bad both checked = 24 at 50hz, bad Perhaps it's a madvr bug that can be worked around by using reclock runevent.vbs and disabling madvr switching.

Users who usually check the "treat 25 as 24" are those that have a 24Hz multiple refresh rate in the list of valid refresh rates that madVR can choose from. That setting is moot if you don't have a 24Hz refresh rate and causes more harm than good in such a situation. |

Just because you can send that to your TV doesn't mean it runs the panel natively at that rate. I would be very careful with the non-standard rates, and do thorough checks to ensure it doesnt internally mess everything up, like most TVs do.

Are smoothmotion testpatterns sufficient? This displays specs are 56-82hz but 48 and 50hz show no judder in testpatterns. Last edited by turbojet; 23rd March 2013 at 07:42. |

This was true in the early days of flat panels, it is not now. Any review of an HDTV will tell you whether it natively displays 24p/23.976p content properly. And again, pretty much all TVs sold in Europe can do 50 Hz and 60 Hz natively, even the old CRTs that were made long before HD or 24p BDs.

I just got ahold of a high-end flat screen CRT and 24p@96Hz looks so amazingly smooth! Yes, it's darn small but black is as deep as on a TOTL Plasma(0.03 cd/mē) and movies look as smooth as they will ever get IMO BTW, I recently tried a bunch of LCD TV's, they would all support 48Hz but that would hiccup very badly.....hell, even 24Hz hiccuped on one of them, hah!

Which would mean they don't actually support 48Hz, and just fake it.

Well I own a Samsung M86 series (LN61?? in North America).
It was a tv advertised with no "official" 24p support, but it does accept a 24hz signal when forced, its just not in its EDID. So this leads me to believe that 24hz mode on my tv and probably many others, either isn't implemented well, or converts the refresh rate itself and I can't believe they would invent technology that equals a multiple of this refresh rate, if displays already displayed 24hz ok. How exactly do you know that each display is infact showing 24hz? I can't think 120mhz+ tvs were designed just for frame interpolation. |

Not really related but also note that TVs sold in the USA (possibly all of North America) are intentionally crippled to lack 50 Hz support.

Anyway, I see that there are patents explaining how to mimick the way a CRT works: http://www.google.com/patents/US7324933 I'm sure madshi already read those pages anyway, and I guess that me complaining about how his frame blending looks like a ghost story on a CRT is a gross misjudgment as CRT's work very differently from the rest anyway. I've ordered yet another LCD TV(not an edge-led model this time, though ), so I'll try my luck again ^^ And going back to Sammy TV's, I find the DNIE effect really obvious on the BBC screencap used in this review: http://www.hdtvtest.co.uk/news/samsu...ge=Performance I'm just a little confused when they write: Quote:

Perhaps they are talking about the fact that fast motion in video results in a lot of detail loss. I remember reading a study that showed very high refresh rates (200+ Hz) hugely increased perceived detail during motion, even more so than increasing spatial resolution (e.g. 4K vs 2K). UHD is meant to support 100/120 Hz progressively scanned video so hopefully that is what future broadcasts will use.

You mention the difference to be "obvious" but there is still no definitive way to test, unlike using a test pattern for colour! Sent from my Blade S using Tapatalk 2 |

Do you need a test pattern to see whether a TV is colour? I'm done with this conversation, if you really can't use Google to look this up then I can't help you.

Comparing this to whether a tv is colour or not is like comparing whether a TV refreshes or not, not whether it refreshes correctly. Sorry to antagonise you, not really my intention. |
