at this point it would take a detailed guide compiled by advanced user who has fully understood and acted upon the meaning of the procedure, described schematically by Hannes69.
Quote:Managed to do it, thanks! Feels good not being at the mercy of Nvidia's drivers anymore.Glad it worked for you. I don´t have any experience with nvidia, with my AMD there´s no range problem and I´m using RGB for all presets.
To output correctly I needed to set it up as YCbCr 4:4:4. RGB was messing up the range through HDMI (didn't use to before).
Quote:Does anyone know of a calculator to show the expected frame drops/repeats based on the clock deviation percentage? Or what would be the formula? I tried "something" but the results made no sense and I suck at math!I´ll try:
Quote:I just deleted my custom resolution for 23.976 and the deviation-% went out of whack. Previously it was ~0.00088% and now way over 0.02000%?!Hm, here I have no idea. The clock deviation should be independent of the used resolution...
Quote:My .00001% deviation drops a frame every three and a half minutes. This doesn't make sense. The clock deviation can't be accurate.It could be possible. Let´s take the above formula, take your given numbers and ask for your real refresh rate. I assume we are talking of 23.976fps movie that has to be played back with a 23.976Hz refresh rate. I take your clock devaition of -0.00001% and your "1 frame is dropped every 3,5 minutes".
Quote:I gave up on trying to describe custom resolutions in the guides I maintain. Two many variables can cause problems and DSPlayer has been less stable, too.I understand that. The problem is by nature, the thing with custom resolutions and perfect refresh rate is kind of mathematic / scientific thing. And I know that most of the people in this world are at war with mathematics
Quote:Does anyone have a good link on custom resolutions? I'd rather provide a link with great detail than attempt to add this topic to an already packed tutorial. It is really only a tool for advanced users.Sorry, I have no link or direct description in this matter.

Been away from the forum for a bit, has there been a DSPlayer build based on 16.1 ive missed?
Cheers in advance

Quote:Clearly madVR OSD is displaying the "corrected" deviation numbers, not the actual clock deviation"No. Madshi (the author of madvr) explains himself the story about the clocks here, glad I found it.
Quote:the deviation continues rushing past what it was supposedly stabilized at before, then gradually slowing down again and setting at a notably different percentage.There seems something odd in your setup, that´s definitely not the normal behavior. There are small variations (because of heat, electronic effects...) but not that huge. Maybe worth a try to look at the BIOS setting regarding HPET support, this may influence the clocks. No other idea beside that.
What's more, I get different deviation percentages with different 23.976 movies. The difference can be as large as 0.04%.

Nice explanation of the target refresh rate! Please correct the typo "Target refresh rate = 23.97602 * 0.9999758 = 23.79544" in order to not confuse the people even more

I assume this could be the source of the the varying clock deviation figures but would someone be able to explain how exactly? Is the same audio clock of an HTPC used for all outputs, for example?The audio clock in this case is in your motherboard audio chip. The video clock could be a in separate GPU or in an onboard GPU, but it's different from the audio one nonetheless.
