VGA (D-SUB) -> HDMI converter only 1024x768p resolution

I have an old laptop (Acer One) and I've successfully installed the latest Kodi on it. I bought a VGA to HDMI adapter for it and connected it to the TV. The problem is that I can only set the resolution to 1024x768. (I checked the xrandr output over SSH.)

When I connect the laptop to an old monitor using a regular VGA cable, I can available Full HD resolution.
Also, if I connect the adapter to a computer running Windows, Full HD resolution is available as well.
Do you think there's a solution to this?

Connect the old monitor again and run getedid create to save the resolutions.
