Dual monitors on GA-78LMT-USB3

[SL2017]

Hello,

I have a motherboard from Gigabyte: GA-78LMT-USB3 and two HP monitors (both identical, supporting 1920x1080 screen resolution).
When using one via HDMI it is able to use max resolution (1920x1080) but when I add a second one using VGA (D-SUB) the 2nd monitor's max resolution is only 1600x... (which displays out of range error on the monitor and the one that doesn't display error is 1440x900).

The link for the motherboard is: https://www.gigabyte.com/Motherboard/GA-78LMT-USB3-rev-60#sp
Unfortunately it does not say anything about the inability to use max resolution on the 2nd monitor.
It only says "Simultaneous output for DVI-D and HDMI is not supported" but this is not my setup.

Does this motherboard support such setup or do I need to purchase an external video card (GPU) that does?

Thanks.

That's an integrated GPU from an entry-level chipset debuted in 2009. It's difficult to find any hard specification for it since at the time the 9xx chipset was far more popular.

I'd guess it's simply doesn't have the capabilities. It's 8 years old and even when released it was considered low-end/entry level.
