Dynamic Refresh Rate not working (2 Viewers)

[Urban51]

I am unable to create CCC profiles for every refresh rate, because CCC allways jumps back to 24/60 when choosing 23/59.
It seems to be a only GUI related because MP reports 23.9 Hz and practicly no dropped frames and flat lines with 23.9 Video. Playing 25p Video gives frame drops and peaks in lines.

Attached debug info of case: display set to 23p (shift one confirms that) and started 25p Video with refresh rate changer activated.

^ you dont have ccc profile setup for 50hz

As the log says, I dont use profiles but the switching via windows api (command line left empty). Using profiles was a trial work around which didnt work well for the described reason.

Can you please show me a screenshot of mediaportal in "23.9"hz. Press shift+1 and play video. I need to see the reported + measured refresh rate. After that use CCC profile to do 24hz and repeat the screenshot.

Spoiler

To Confirm:
1. Internal refresh rate doesn't work in Win8 for any hz settings?
(and)
2. CCC can change to "23.9"hz when you do it manually, but when you use a profile in CCC it can not?

I suggest you do the following
1. Use CCC profiles or 12noon with 24/50/60hz using DDR external mode
2. Enable MPAR with timestreetch + vsync
3. Disable vsync correct in audio codec
4. Let us know how that goes.

You should use 50hz for 25fps video.

i made the screenshots.

confirmed:
1: yes, internal win8 rate switching doesnt work (someone with Intel HD4600 seems to have the very same Problem)
2: yes, manually selecting 23p in CCC gives 23p (see first Screen), but the GUI drop down menu shows 24p. The now created CCC Profile gives 24p when DRR activates it (see screenshot). The TV reports 24Hz thus the switching works, but it doesnt tell wether 23 or 24.

In Win7 with PDVD13 codec and internal switching the lines are even flater. Absolutly no problems for months. Thats why I switched back to Win7 after unsuccesfull trial of Win8. Im sure, the syncing methods with MPAR work, but since Win7 works totaly fine without, I prefer not to use such work arounds.

win8 23p.png - This is 23.976hz ("23p")
win8 from 23p with ccc profile to 50p and back to 23p.png - CCC profile has failed to change refresh rate from 50hz back to 23.976hz

so your cc profile is failing, it probably is not setup correctly. Regardless, you might get success using 12noon instead of ccc profiles.

http://12noon.com/?page_id=80

dccmd -quiet -refresh=23.976 -force

I haven't used it with 23.976hz before, but I assume that is the correct command rather than -refresh=23 , but you could try both. ps. i recommend using 12noon in a .bat file with a brief 1000ms pause

call "c:\dccmd.exe" -quiet -refresh=23.976 -force
ping 1.2.3.4 -n 1 -w 1000

PS. Don't think of MPAR as a work around, the fps of a movie is never played back at *exactly* the encoded fps rate, and the refresh rate is never *exactly* the same as what you have set it to.

About Win8, @tourettes has some issue related to a BIOS function and all was ok after disable it (i don't remember the correct option but seems related to Virtual option)

Win8 works really great for me too

 

[Urban51]

with 12noon Display Changer it works great. Now I even can change rate via IR
I had some stutter with Sopranos, but the files got some errors. With clean Game of Thrones I could not recognise any problems.
@kiwijunglist: your frequent post editings mess me up. the mail notification has different text and now again there something else. using dccmd without pause cuts i little video but it feels faster than internal switching.

The built-in refreshhrate changer doesn't seem to be working for me either on Win8 with amd graphics. The notification popup is shown but the TV doesn't switch.

This worked fine with 1.3 on win7 and I can manually change the refresh rate in Windows. I have just one screen connected (and no RDP sessions).
