My effects panel is small and not sure where to change the size, there's no option in UI settings
Did you change anything in your system monitor settings? Made UI elements larger or smaller? This might throw Illustrator off its path.
Apart from that: you can try and reset the Illustrator preferences (which will erase all your settings) https://helpx.adobe.com/illustrator/using/setting-preferences.html
I have two monitors, my main one is widescreen and the other is a smaller flat screen. On the widescreen, the effects drop-down options are normal size with the rest but when I switch over to the second monitor the effects drop-down gets significantly smaller than the others. I've kept the system settings on default on my main and the smaller one is on a game setting. I reset the preferences, restarted my PC, uninstalled and reinstalled illustrator and it still gives me that small effect dropdown menu.
Unfortunately Illustrator reacts in surprising ways when you set up your monitor differently in the systems preferences. Maybe someone else has a bright idea to permanently solve this.
Hi @Art Moofin,
Thanks for reaching out. The product team is aware of this. The effects menu is programmatically drawn and doesn't use OS UI. It matches the main display's size (DPI & resolution) and will look different on different monitors with distinct resolutions & DPI. We have already logged a ticket with the product team to make the menu look similar to the latest OS UI look and feel across all the monitors & displays regardless of the DPI and resolution.
I hope this clarifies!
