Both 22". Not really looking for anything bigger tbh. Only difference is one has VGA, the other is VGA and DVI, and a £10 difference in price.
Oh yeah, the LG has a refresh rate which is 15hz higher (75hz)
Go with the Acer if you're only deciding between these two because it offers the DVI interface.
VGA carries an analog signal and is currently being displaced by DVI and HDMI. Even though both VGA and DVI can carry HD signals, there is a noticeable visual difference between VGA and DVI and you will want to have the better connection available. .
