hdmi to vga converters are with chips, no chip can not achieve hdmi to vga. Hd hdmi signal is a digital signal, and vga is a kind of analog signal to drive the computer monitor, hdmi signal to vga signal is to go through the digital-to-analog conversion chip, digital-to-analog conversion, so as to get vga signal. So you have to have a chip.
The conversion of the chip inside the HDMI adapter is definitely better than that without a chip.
