Dahua A221Y 27" IPS Monitor 144Hz 1920x1080

Only HDMI does. On Dahua's sheet the HDMI 1.4 port carries 144 Hz while the VGA port is held to 75 Hz, so a computer on VGA will not see 144 Hz.

The copy of Dahua's sheet on Dahua's own file server gives 144 Hz for the DHI-LM27-A221Y. Dahua's sheet, in a later revision, describes the panel as 120 Hz, overclocked to 144 Hz, and still gives 144 Hz as the top HDMI figure.

Dahua gives MPRT 1 ms on the file-server copy of its sheet. On a later copy of Dahua's sheet, the same row reads OD 5 ms, with the MPRT figure kept beside it.

Yes. Dahua lists 100 x 100 mm. Brackets and arms are bought separately, and Dahua's sheet shows a wall mount only as an optional accessory.

According to Dahua's sheet, an HDMI lead ships with this model together with its power adapter, base and a QR code for the manual. A VGA lead is not among the listed items.
