How can I switch my display from YCbCr to RGB?

On an Apple-silicon Mac with a supported native display connection, open App Menu > [display] > Color Mode and select an available RGB format. The menu may be under the display’s more-options chevron. You do not need an EDID override when the desired format is already listed.

Check the selected mode’s bit depth, range and HDR state as well as its RGB label. The choices depend on the current resolution, refresh rate and connection. If RGB is missing at the rate you want, compare a lower Refresh Rate and inspect the list again. A lower rate may offer additional formats. Choose one that your display and adapter support.

If macOS later selects another format, use Configuration Protection > Color Mode, or HDR Color Mode for the HDR state. Protection requires Pro and BetterDisplay to remain running. It can restore the format while the connection still offers it. See keeping a selected color mode.

If RGB does not improve the image, check subsampling and output range as well. YCbCr 4:4:4 retains full chroma detail. Subsampled 4:2:2 and 4:2:0 can reduce detail at colored edges. An output-range mismatch or the monitor’s own processing can also affect the result. See washed-out colors and chroma subsampling for how to check these causes.

The Color Mode selector is unavailable on Intel Macs. An advanced alternative is to apply a prepared custom EDID through System Configuration. Removing advertised color formats can also remove HDR, resolution or refresh-rate choices. Do not use Write EDID to Device for a software override or copy another monitor’s EDID as a universal RGB fix.

The Color Mode reference explains the selected and preferred formats and additional options.
