Review of BenQ EW2420 Backlight LED Monitor

After spending some time with the monitor today i thought i'd post my findings here

Firstly i've had a real mare setting it up regarding colour,contrast and brightness and at one point today was 2 clicks away from buying a calibration tool. After 3 hours i've finally settled on what i think is best for me which is as follows

brightness 32
contrast 60
sharpness 3
gamma 2.2
red 88
green 88
blue 86
AMA on

This seemed to give me the best possible all round quality and colour for my pc and ps3.

Right onto what i think

Firstly backlight bleed, direct(face on) on the unit suffers no backlight bleed only when moving to a 70 degree angle to the left or right can i start to notice a bluish tinge to the 2 opposite corners, it's perfectly acceptable as most people do not view their monitors from obscure angles on a daily basis.

Next i went on to test the ghosting/trailing i've seen a lot of people talking about. Yes there is some ghosting to be seen especially when going from extreme white to black very quickly. The best example I found of this was by going to this webpage http://www.lagom.nl/lcd-test/contrast.php also opening up a second tab with googles homepage on there. Now switch to the langom test page,wait 10 seconds then switch tabs to google homepage and you will see the 15 black boxes from the langom page drift away on the google page. I timed this 5 times and made a average of the time it took for googles homepage to become white again. The average time was 2.1 seconds remember that is an extreme example of black to white transition.

Next I tested ghosting/trailing in game the games I tested today were.
Metro 2033
Splinter cell conviction
Crysis warhead
Resident evil 5
Alien Vs Predator
Killing floor
Need for speed shift

I can honestly say it is not a problem in any of the games I tested, yes it's present in a minor form but unless you are specifically looking for it then it is something that is not going to affect you in your everyday gaming sessions. Even using splinter cell convictions sonic goggles which show white,grey and black I did not notice and trailing which would inadvertently affect your gaming.

Onto the picture quality using the same games mentioned above

One word can describe my experience very well and thats WOW I have never seen any of my games look so good the colour reproduction,transition and a feel of depth to the scenes were immense at some parts, Crysis warheads greenery looked vivid and lively, right down to metro 2033's dark damp tunnels and stinking sewers . I think the reason things look so good is down to the semi gloss coating of the screen itself. I really cannot explain any more how good the quality is from this monitor especially in it's price band.

Movie and high definition playback

This was also a joy to watch blacks were deep and dark and not the usual greyish blacks I was used to from my old TN panel. My movies of choice were Terminator salvation and The matrix on blu-ray, both looked stunning using the Playstation 3 as the playback source. I actually got sidetracked from what I was doing watching Terminator it was a joy to watch the 40 minutes or so that I did. Once again colours were top notch.

My final verdict

I think at this moment in time and in this price band the BenQ EW2420 is a cracking all round monitor. And other companies definitely have to pull something special out of the bag in this price range for me to consider switching again to another brand.

Any questions then please feel free to ask and i'll answer best I can.

****Also sorry if it seemed long winded it is my first time reviewing anything!****
 
Thanks for the review it's very good to see. :)

I would just like to pick up on a point you made -

"going to this webpage http://www.lagom.nl/lcd-test/contrast.php also opening up a second tab with googles homepage on there.

The average time was 2.1 seconds remember that is an extreme example of black to white transition."

I've done that several times myself and the transition is almost instantaneous. It is supposed to take this monitor 25ms for a white-black-white transition so if it's taking 2100 milliseconds to go from black-grey to white and you see afterimages that's something else (not the monitor). I can't think what exactly it could be but I don't get that on my system.
 
Definitely something wrong there, no transition on any LCD screen should take 2 seconds. Maybe a browser problem? If the monitor was reacting that slowly to light/dark transitions it would be useless, you wouldn't even be able to see the mouse cursor move.

And light/dark transitions are VA's strength, it is dark/dark (ie, going from black to dark grey for example) that it is slowest at.

mmm it just seems to be doing that set method i used doing it any other way results in almost instantaneous transition.

i opened up photo shop and put some black squares around a white background and flicked to google and it turned white instantly, i did the same but with black squares and grey background and got the same result turned white instantly.

Musy be a browser problem or something with that specific page that is causing it. I'm going to look into it a little more tho and thax PCM2 for pointing it out and trying it yourself
