At this price I had been running a Linux Ubuntu computer using a 15 crt monitor for a couple of years and it was time to get a decent display.
jlambrec 3:53am on Saturday, September 4th, 2010 
Sleek, Sharp & Stunning I mainly use this monitor to play ps3, 360 and Blu Ray movies. Great screen E2400HD is one of the best screens out there with very vibrant colors and and great contrast and black levels. Ben Q E2400HD This monitor is great, I only use for watching movies and playing xbox 360. Picture looks fantastic, very easy to set up. very fast shipping i have ordered a lot of stuff on line and i have never wrote a review but i think this monitor is worth one.

I bought this because I wanted to play my PS3 in HD, as well as for extra screen space because I have the 13" Macbook Pro.

I bought this because I wanted to play my PS3...  I liked the cheap price, 1080p resolution, HDMI connection. I must say, having this monitor for the past ...  This monitor was great for me as I wanted a 24 inch that was Full HD, 1080p, 16:9 display.
navara 11:53am on Wednesday, April 14th, 2010 
Good quality monitor for a very decent price After almost a year of usage I have no complaints about this monitor at all. Question Why do the specifications state that this monitor has a 2ms response time, when the Benq website quotes it at 5ms?
