BenQ EW2420 Monitor Review
by Chris Heinonen on October 13, 2011 12:00 AM ESTLag Measurements and Gaming Use
As with my previous review, the BenQ was evaluated for gaming use by testing the lag using a comparison to a Viewsonic G90f CRT monitor setup with a mirrored desktop in Windows 7. Both were run at XGA resolution and at 75 Hz through the opening demo loop in the 3DMark03 benchmark test. I used my SLR to take images at 1/320 of a second and then analyzed the data to find the average amount of lag between the two monitors. The BenQ has a feature called AMA, or Advanced Motion Accelerator. I ran the tests with this enabled and disabled.
I didn’t notice any difference in the response time with AMA enabled or disabled in use, and the test results seem to show that’s the case. Similarly, with or without AMA, I didn’t notice any issues when playing any games. Motion is smooth without ghosting, and no lag is present that I could blame for my horrible FPS skills at this point in my life.
Response times are around 6ms and very good overall, right up there with what faster TN panels can manage. This is the one area where we’ve seen BenQ use MVA panels in the past (instead of PVA), with the result being faster response times. Overall, the BenQ performs very well in the lag and gaming tests.

Can you guys review the new Samsung SA950? Heard it was a great 120hz monitor with very good colors for a TN panel.Operandi - Thursday, October 13, 2011 - link
I'll throw my 2 cents in by saying please don't bother reviewing any TN panel.EnzoFX - Thursday, October 13, 2011 - link
Agreed!wicko - Thursday, October 13, 2011 - link
Next time you should keep your 2 cents.GeorgeH - Thursday, October 13, 2011 - link
This. TN panels have their place, especially in a market overflowing with 120Hz IPS screens.Next time try replacing 'TN' with '27" 1080p'. ;)

Here's a universal review for any TN panel: buy the cheapest panel in your desired size. It will suck. If you don't notice it sjkostans - Thursday, October 13, 2011 - link
Yeah unless you're talking 120Hz which is a completely different story. There are people out there that aren't satisfied with 60Hz for gaming.wicko - Thursday, October 13, 2011 - link
Yeah because there is only one quality of TN panel: crap.We get it, you're a panel snob, move along.

I can't tell if you're being sarcastic or not, so I'll ask- What 120Hz IPS screens?dqniel - Thursday, October 13, 2011 - link
Some people require 120Hz panels for competitive gaming. Not everybody's needs will be met with a PVA or IPS panel.I'd also love to see some 120Hz panel reviews/comparisons.
