Maybe if I could find some alternative drivers.The issue might be because you're using a DVI-HDMI cable. Technically a DVI port can act as an HDMI port, but single-link DVI normally should not exceed 165 MHz pixel clock, so the driver might not be allowing that on the DVI port even though the hardware is technically capable. You would have to use straight HDMI or an active DisplayPort to HDMI adapter to avoid that limitation. |

RE: Custom Resolution Utility (CRU)
the interesting thing is that everything works under linux, so the cable is OK.
I can add 2560x1440, 60i (interlaced) resolution via CRU, but when I switch to this resolution the image on the monitor is broken |

Why does a DisplayPort-connected monitor to a PC have CTA-861 data blocks such as "Colorimetry" (with xvYCC, bt2020, and other modes checked + md0), "Audio formats", "Speaker setup" and "HDR Static Metadata". Isn't a VESA DisplayPort supposed to support all of these in a PlugnPlay fashion? Perhaps these are for connecting the monitor to a console I'm assuming? It makes no sense to have Colorimetry for example when I read that it's strictly an HDMI setting. Was curious about that.CTA-861 data blocks are not specific to HDMI. DisplayPort supports colorimetry, audio, and HDR. |

The colorimetry color spaces have nothing to do with the output color format, and I'm not sure Windows even uses the colorimetry information. Just make sure the YCbCr 4:4:4/4:2:2 color formats are disabled if you only want RGB. |

RE: Custom Resolution Utility (CRU)
I need some assistance trying to use cru. I have the hz benq zowie xl2566k and I cant use the 360 hz and when I try to change my resolution through "List all modes" black bars just appear when I press "okay"

@ToastyX
Could you point me to an EDID file that's unlocks everything and optimized for a 55in LG CX? I mainly want to solve screen flickering on and off randomly on PCs. From what I read online it might have to do with either Gsync or VRR but unsure thanks |

Just make sure the YCbCr 4:4:4/4:2:2 color formats are disabled if you only want RGB. Appreciate the fast responses. I ended up reset-all defaulting my monitor because i changed wayyy too many things and it looked very off. Currently at default CRU and just ended up making a custom resolution. My display resolution is 143.981hz in windows. I went into nvidia control panel and I made a custom resolution to add the same res (1920x1080), selected manual timings instead of automatic and i raised the refresh rate to 144.001. Created the custom res and everything looks smooth with no noise and full RGB colors. I noticed after creating this res, my windows displays the refresh rate at PURE 144hz now instead of the old 143.981. I'm guessing this is where nvidia overrid it, hence why things look and run great. Is it ok to have windows show 1920x1080 @ 144hz from my old 143.981? How important is it for the pixel clock rounding to happen? Seeing as I basically canceled it I'm a little curious lol |

Flickering on/off is often a signal quality issue. Make sure you have a certified 48 Gbps cable. |
