Passive DisplayPort to HDMI adapters are limited to 165 MHz unless the driver is patched. Make sure to override this and set it to 340 MHz. Older cards are limited to 165 MHz unless the driver is patched.ĪMD/ATI's driver also listens to the TMDS clock limit in the HDMI support data block. AMD 7000-series and newer cards support up to 297 MHz. HDMI is treated as single-link DVI unless an HDMI support data block is defined in the first extension block. Single-link DVI is limited to 165 MHz and dual-link DVI is limited to 330 MHz unless the graphics driver is patched: "Automatic - CRT standard" uses timing parameters compatible with CRT monitors. This may help when trying higher refresh rates. "Automatic - LCD reduced" adjusts the timing parameters for some resolutions to reduce the pixel clock. "Automatic - LCD native" uses standard timing parameters for the native refresh rate. "Automatic - LCD standard" uses standard timing parameters commonly used with LCD monitors and HDTVs. The dialog will always open in this mode. "Manual" allows the timing parameters to be set manually. Use the timing options to help fill in the values: The graphics driver will automatically add some common lower resolutions as scaled resolutions. All other resolutions can be removed if they are not needed. The first detailed resolution is considered the preferred or native resolution. More detailed resolutions can be added using extension blocks. This can be done in safe mode if necessary.ĭetailed resolutions are the preferred way to add custom resolutions. To reset all displays, run reset-all.exe and reboot. To reset a display back to the default configuration, use the "Delete" button at the top to delete the override from the registry and reboot. Windows Vista/7/8/8.1: right-click on the desktop > Screen resolution > Advanced settings > Monitor tab Windows 10: right-click on the desktop > Display settings > Advanced display settings > Display adapter properties > Monitor tab Set the resolution in the Windows display settings. Restart the driver again to reload any changes. This will temporarily unload all the EDID overrides without deleting them. If the display does not return after 15 seconds, press F8 for recovery mode. Run restart.exe to restart the graphics driver. Import follows the same logic unless "Import complete EDID" is selected. It will not copy the name or serial number, but it will copy the inclusion of these items using the monitor's own information. The "Copy" and "Paste" buttons at the top can be used to copy the resolutions, extension blocks, and range limits if included. Repeat steps 2-3 for other monitors if required. Please read the sections below for more information. "*" means changes were made and an override was saved in the registry.Įdit the configuration as desired. "(active)" means the monitor is connected and recognized by the graphics driver. Choose a monitor from the drop-down list.
