Please tell me what to do in this case?Yes, but possibly for external displays only. Intel seems to be restricting laptop screens for some reason. |

Flickering also does not begin until about 35Hz, which would require setting a limit of 25Hz~, as LFC kicks in roughly 10Hz/fps above. Nobody plays or wants to play games at this low framerate anyway. LFC flicker is caused by pixel decay on the LCD, since a pixel fades to its rest state when not refreshed for too long. Different panels have fast-fade behavior and others slower-fade. That's why I recommend to many people to manually edit min Hz to a higher number to prevent display flicker -- but not all displays require that. LFC stutter penalty is linked to max Hz, so it is extremely minor when the VRR range is wide (e.g. 240Hz). For example, compare a 120Hz FreeSync monitor to a 280Hz FreeSync monitor -- a 0.5/280sec error margin (stutter) is extremely invisible compared to a 0.5/120sec error margin. So the higher your max Hz, I recommend a higher min Hz as long as (min,max) is about 3x or thereabouts. LFC is a software-based mechanism (driver-initiated refresh cycles) in generic VRR implementations. Also, NVIDIA drivers (in G-SYNC Comaptible mode) sometimes override the LFC min-Hz and arbitrarily choose a higher LFC min Hz, at least in a 'sticky' manner. So if framerate falls a lot to trigger LFC, framerates need to rise a lot before LFC automatically disables. AMD drivers have a different LFC-stickiness/stiction algorithm. You can watch this via the monitor's OSD framerate counter (more accurately refresh cycle counter), since this number will suddenly double or triple when LFC is initiated, so real GPU 35fps would read as 70fps in the monitor's framerate counter (which I prefer would have been named "refresh cycle counter") Try AMD, try NVIDIA, you'll see different LFC algorithms running.

I do watch Hz in OSD during Pendulum demo and 80-240Hz is jarring when brightness flickers/fluctuates from LFC engaging/disengaging. So either I lower it so LFC never engages, or raise it (120Hz max) and cap FPS so it doesn't exceed/disengage LFC, which isn't ideal for all games. Or I raise it and don't cap and deal with less worse brightness flicker/fluctuation from LFC. I'd like to not deal with any brightness flicker/fluctuation. This is the type of thing I'm talking about: https://youtu.be/XDWOHT5qrI8 Dreadful. Doesn't capture it perfectly but look at all the shadows and darkness in the background etc, the color tone/brightness of the sand etc I can also see change which maybe isn't picked up as well in this video. No thank you. It's like there's lightning going off behind the camera in the Pendulum demo. |

RE: Custom Resolution Utility (CRU)
Hi ToastyX. I'm trying to use CRU to set a 640x480 resolution on my Mitsubishi 930sb CRT monitor. Whenever I add it in CRU it does not show up in Nvidia control panel but my other 1200x1600 resolution does. I use the CRT timings drop-down and has tried multiple refresh rates to see if that would change anything.
If I create a custom 640x480 resolution in Nvidia control panel itself it will let me apply it and work fine but as soon as I turn the system off, turn either monitor off or change the resolution back up. The custom resolution disappears and I cannot recreate it until I cycle the whole computer. I'm using a 30 series GPU with a display port to vga adapter if that important Thank you in advanced toasty, love the programme! |

Also keep in mind some GPUs might not support digital signals below 25 MHz pixel clock. |

You need to make sure the extension block has an HDMI data block. Allright I managed to get it to work by following the following steps: 1) Download the hdmi2-bitstream.dat - HDMI 2.0 support with bitstreaming audio formats 2) Open it in CRU 3) Add 5.1 speaker setup and changing all bitstream formats to 5.1 4) Export as .exe 6) Run .exe 7) Reboot After some testing, it does see 5.1 now but when I test speaker sound, only the stereo front left and right work. Partial Victory: |

RE: Custom Resolution Utility (CRU)
Hi,
I am read everything from extension blocks to all the posts in this thread about 360hz. But everytime I try adding a displayid 1.3 with 360hz for native (1920x1080) and the custom (1720/1080) and delete all default extension blocks nothing seems to work. It restarts fine. But when i go into display adapters to set the mode the screen goes black and resets to 1920x1080 at 60hz. It even goes black when I set it to 1920x1080 at 360hz using the displayid 1.3. I have the nvidia settings set to display scaling as well. the monitor is a ROG PG259QN. Thanks for any help. |

The PG259QN can't display non-native resolutions, so you'll have to use GPU scaling for 1720x1080, but I don't see why 1920x1080 @ 360 Hz wouldn't work. Export a file with the changes you made and attach it here. |

RE: Custom Resolution Utility (CRU)
Hello. I'm trying to remove HDR functionalities from my ASUS PG329Q with CRU, but it doesn't seem to be working.
I'm removing the "HDR static metadata" data block, and restart the graphic drivers with the Restart.exe file, but windows continues to recognize my monitor as HDR compatible. What am I missing? Do I need to remove other data blocks? Or do I need only to slightly edit the HDR one? Thank you for your help. |
