Installing DietPie on Rock64 and set 1280x1024 resolution

Thanks in advance for taking the time of reading this and possibly trying to help.

I recently got a 1 GB ROCK64, and I want to install DietPi on it. I have a 32 GB Class 10 micro SD card, a Realtek RTL8188EU Wi-FI USB dongle and a wireless keyboard + mouse combo, so up to this point I assume I'm properly equipped for the installation. The thing is I don't have any 1080p TVs or monitors (I live in Venezuela), but I do have an HDMI to VGA converter, which I'm planning to use with a 1280x1024 monitor.

I already tried flashing the image to the micro SD card using Etcher, and the ROCK64 seems to boot up but no image appears on screen. I presume that it is booting up because the mouse turns on when I power the ROCK64.

Although I'm a Linux user, I'm completely new to the SBC world. Please, do keep that in mind.

I want to know how to change the resolution so I can proceed with the installation. I already tried Googling this issue, and even though there is comprehensive information on the subject, I couldn't find a specific solution for the ROCK64. I don't know which file I have to edit to change the resolution of the output.

I presume the issue is exclusively the output resolution, but I can't be sure. I hope someone more experienced can tell me what possibly could be wrong.

I have to add that all 3 lights of the board turn on and stay like that. I haven't tried leaving the board on for a while.
