The VGA signal is generated by a dedicated graphics processor built into the STM32 chip (called the Chrom-ART graphic accelerator). This generates precise VGA signal timings and results in a steady image with very clear characters on the screen. HDMI cannot be generated by the Chrom-ART graphic accelerator so we would need to add an expensive and complex chip which in the end would cost a lot more than a cheap VGA to HDMI converter.
If an HDMI output is required we recommended that an inexpensive VGA to HDMI converter be used. These cost about US$10 on eBay and will also encode the audio from the computer. As an example, the Colour Maximite 2 was successfully tested with this device: https://tinyurl.com/w5woobe.
