It may have something to do with the fact that it has the HD 4250 integrated into the motherboard/chipset, AMD M880G Chipset
as well as the dedicated HD 5650 installed in it, which is normal with all AMD xxxG series chipsets. With that said if this was a desktop it would just be a matter of going into the bios and disabling the onboard video, but with it being the laptop variant and from Acer that may not be possible. If you haven't have a look in the bios and see if the option is there, and if so disable it and see if that also fixes the HDMI problem.
