I have been struggling with finding a fix for quite some time. I wonder if you could point me in the right direction.
Here is the issue:
I am playing a lot of European video content encoded at 25fps. It plays fine on my newer TV, but not on my SONY Bravia KDL-60EX723 TV.  It flickers several times a minute. I think this is because  that TV is lacking resolution support with refresh rate that are multiple of 25.
Here is my setup:
OS- windows 10
Video card: Nvidia GTX 1050Ti
Maximum resolution available in the Nvidia control panel:  1080p 1920x1080
Refresh rates available for this TV - 60, 59, 30, 29, 24, 23

Paradoxically, the content plays fine under PLEX and Windows 10's native "Movies and TV" app. However, the same flickering takes place when using VLC player.
I have tried many settings in madvr as well as letting JR to manage the refresh rates vs living it to madvr, etc. No luck whatsoever.  Any help would be appreciated.

Try turning on smooth motion in madvr

Turning on smooth motion in madvr made no difference. The problem persists. Please keep your suggestions coming.

Can you post screen shot of madvr OSD with smooth motion on.

Also ... check your TV ... maybe you can change pal/ntsc manually ... should be somewhere Settings -> Video Settings -> NTSC/PAL settings

[edojan]

Here is the screenshot. I will check the TV settings to see if there is such an option. If so would enabling it cause an impact to NTSC content playback?

[tij]

Indeed smooth motion is engaged ... strange that it did not improve anything (it will not eliminate problem completely ... just make it less bad).

As for TV ... if indeed it has option to change pal/ntsc ... then you need to switch before playing movie ... hopefully it has auto.

Setting the screen refresh to 23hz with the smooth motion helped to stop the flickering. Interesting, that the flicker is back with other refresh rates such as 60hz or 59hz. The problem with 23hz and smooth motion --a lot of artifacts whenever there is any movements on the screen.  The moving objects lose sharpness and aquire  trailing ghostly shadows

and I have checked to see if the TV has a setting for PAL - it doesn't

[tij]

Try this

[options]->[video] enable VideoClock

In madVR [devices]->[your tv]->[display modes] enable treat 25fps movies as 24fps

EDIT: try enabling VideiClick first ... if it does not produce smoith okayback, then try madVR 25fps as 24fps

tij, thanks for your help.

Enabling Video Clock in JR and disabling smooth motion in madvr did the trick. To summarize, in order to fix the frame dropping / flickering issues with 25 FPS content playback on a tv which lacks refresh rate capabilities that are multiple of 25:

1. Manually set the tv refresh rate to 23 hz at 1080p 1920x1080  (as mentioned, the screen flickers badly if the refresh is set to 60 or 59, and flickers less frequently if set to 24)
2. Enable Video Clock in JR
3. Set Display Settings Automatic Change mode to custom

Red October HQ is enabled with best quality settings (my 1050TI card seems to handle this ok)

Glad it work out for you ... though i am surprised 60/59 fps flickers with video clock and smooth motion ... maybe its source dependent ... ie progressive 25 will work best at 23/24 ... while interlaced 25 will work best at 59/60? ... all speculation as i dont have much time these days to test

[edojan]

I will see if I have any content with interlaced 25fps and if so, I will test it at 59/60hz
