I have followed along multiple tutorials of filling a ComboBox with Supported Resolutions for screens, but it never seems to work. There are no options in the Combo Box. See below for the blueprint and ComboBox. ![307104-bp.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/b/9/2b937b908c4b6d5cefb36a3a8e444021401b90bd.png) ![307105-no-dropdown.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/e/5/2/e5251d2f9fe4b2b5762ae71a874f05c304c68aca.png) My apologies if it is obvious, I am very new to Unreal. ---

You’re doing it right. I don’t believe if fails because of the UE. The issue must be in your monitor(s) or drivers. I have the same thing in Linux. In Windows this setup works perfectly, but in Linux there are no options, just like in your case. Although I have the same GeForce experience installed both in Windows in Linux, UE can’t get the supported resolutions in Linux for some reason. So maybe you should look into other software/hardware to see why it doesn’t work in your case. Edit: P.S. My workaround is to check the array length, and if it’s 0, I just populate the combo box with most standard resolutions. I.e. I manually created an array of standard resolutions and I just feed it to the combo box. ---

I know it’s late, but I’m also having this issue on windows. I’m trying to collate a list of supported resolutions, but I only get 1024x768 returned, regardless of Monitor/TV, GFX card etc. ---

In-case your issue is the same: make sure you’re not clamping your index integer that sets the resolution. I was wondering why my resolutions only went up to 1200x800 and it’s because my index was being clamped to 4 ---

My issue was that I was setting everything in the for each loop, which exited after the first run-through. Operator error!
