Good to know what the asterisk means, and why the monitor doesn't expose the proper resolution. Unfortunately I have to use HDMI because the monitor is hooked up to multiple computers and only has one DP port.(07-04-2024 06:07 PM)nikif002 Wrote: I am having an issue where custom resolutions stopped "taking" for me. I am on Windows 11, Dell XPS 9510 laptop. Hooked up to a Dell U3011 through HDMI and a Dell USB-C multiport adapter.Ideally you should use DisplayPort to avoid having to add 2560x1600 manually because the monitor doesn't officially support 2560x1600 with HDMI even though it will work if you can add it. The * means it is saved. It would say "(restart required)" if it wasn't taking effect. The GPU is definitely capable, so the driver is ignoring the resolution for some reason. I don't know if Intel listens to this, but check the maximum TMDS clock in the HDMI data block in the CTA-861 extension block. It should be high enough to accommodate the pixel clock for the resolution you want. I recommend just putting 340 MHz because that's the standard maximum for HDMI 1.4. |

The R9 280 also has a special mode called UVD that's used when video acceleration is active, such as when playing videos in a browser, and the clocks will stay in this mode if anything is running with video acceleration active. Google "UVD clock bug" for more information. Sometimes it will also change the memory clock when it shouldn't, causing one or both of the screens to display garbage, which might be what's happening when it's booting. Honestly I consider that a design flaw with the first generation GCN GPUs. Newer GPUs don't have these issues, but you still have to make sure the monitors are synchronized. I don't know what you're talking about with the TMDS clock because CRU would never put in 225 MHz if it wasn't enabled already, and that has nothing to do with your issues anyway. That only affects what resolutions the driver will accept, but you don't need to do anything special for 1920x1080 @ 59.94 Hz since that's less than 165 MHz pixel clock. Thank you ToastyX. I did what you said, put same resolution and refresh rate for both, monitor and television, put TMDS clock at 340Mhz, it allowed me today. It works, VRAM returns back to minimum in idle. I did not know about UVD clock bug and saw people are not getting it fixed, it is probably on AMD side. Just one small question, what is Supports ACP/ISRC option in HDMI settings. It comes turn on when I start CRU and I left it that way. I saw that was mentioned on the forum, but I could not find explanation what is that exactly, what is its purpose. |

Windows does not use this, so changing it would do nothing. This was intended for DVD-Audio and Super Audio CD players, so I don't think anything uses it anymore. The HDMI 2.0 specification doesn't even mention it. |

RE: Custom Resolution Utility (CRU)
Hi @ToastyX,
Can you help me? I have a LG MR400-B monitor that sets the native resolution to 1080p@60Hz TV resolutions. I just want to create a PC resolution with a refresh rate of 60Hz. The monitor has 100Hz and 75Hz for 1080p in PC resolution, but since I like to play games at high quality, I prefer to lock the FPS at 60. That's why I'm looking for a full HD PC resolution with 60Hz. What settings should I use for the PC resolution? CVT, Automatic PC, or Native PC? |

TV resolutions have completely different brightness, contrast, and color compared to PC at least on my monitor. Also, there's a noise on the screen for example images and software with gray backgrounds have noise on TV like the image I sent with the post, but on PC even in custom 48Hz resolution, there's no noise at all. I deleted the 60Hz TV resolution and added a PC one, and the quality was excellent. However, every time I login into Windows, the screen would go black for 5-6 seconds, and it was the same before starting games. I uninstalled the driver with DDU and reinstalled it, and the problem was fixed. Now, I want to know what settings I should use when creating the resolution to avoid this issue. |

The reality is there is no difference between TV and PC resolutions other than the CTA-861 standard saying TVs should use certain timing parameters so there are no compatibility issues with other devices, but PC monitors can use them too. The color format can influence how the monitor processes the image. In the NVIDIA control panel, try changing the color format to RGB and dynamic range to full. That should be equivalent to a PC resolution. If that doesn't help, that means your monitor is messing with the image when receiving a CTA-861 standard resolution. Some TVs and monitors are stupid and treat CTA-861 standard resolutions differently when they shouldn't. I don't understand why manufacturers feel the need to mess with the image and make it worse when they think it's a TV signal. In that case, creating a custom resolution using the CVT-RB standard usually works around the issue. The screen shouldn't go black for 5 seconds when logging in. If that only happens after using CRU, then it's an NVIDIA driver bug. In the past, uninstalling GeForce experience would work around the problem, but I don't know if this is the same issue. |

RE: Custom Resolution Utility (CRU)
Hi, I have an issue. I tried to create custom refresh rate, because LEGO Star Wars Complete Saga works only on 60hz monitors and on my 165hz it always displayed an error. I configured CRU and the game finally begun to work, but partially - the screen was all black, although I could hear the music. I discovered that all the other games also get blackscreened on startup. Any ideas how to fix this?

If this is a laptop screen, 60 Hz might work if the pixel clock is around the same as 165 Hz. You can start by copying the 165 Hz timing parameters, and then change the timing to "Vertical total calculator" and set the refresh rate to 60 Hz. |
