DELL's new monitor, U3225QE, can be connected via Thunderbolt 4. I can display 120Hz and Edge and Chrome display without any problems. Only in Firefox there are some areas that should be displayed in white but are displayed in pink. By the way, when connected via HDMI 2.1, the display is 120Hz without any discoloration. If you turn on the dynamic refresh rate, the screen will go black every time you move the mouse. When it is OFF, Firefox browsing does not change color and can be used normally, I called Dell support and they told me, "That's probably a problem with Firefox." It would be helpful if Mozilla could address this issue.
