Successfully installed Catalina but HDMI is not working

Hi, I have successfully installed Catalina on my PC following Dortania's guide, almost everything seems to be working fine. I will list my specs below:

CPU i3 10100 (Comet Lake)

16 GB of RAM

Motherboard: Gigabyte H410M

GPU: UHD 630

The only problem I have is that only the VGA port on my motherboard is working, when I plug in my second monitor to the HDMI port the system slows down, and some artifacts briefly show on the monitor that is connected to the VGA port, but then nothing happens.

I'm using the following framebuffer patch:

        <data>AQAAAA==</data>
        <key>framebuffer-stolenmem</key>
        <data>AAAwAQ==</data>
    </dict>

As I said before, this is the only problem that I've found on my system, hardware acceleration is working fine. I don't care too much about HDMI audio since I always use my PC with headphones pulgged in but I would like to be able to use my second monitor. I would be very glad if someone could help me out.
