BENQ BL2410PT MVA Monitor.

post #1 of 21
Thread Starter 
After reading review of the monitor at Prad.de I ended up buying it. So after using it for one week I decided to write a small user review.

Build:
Build quality is great. Monitor stand is heavy, the monitor does not wobble at all. Small grain matte plastic is used for its construction. It is fingerprint resistant, though not as resistant as large grain plastic. Monitor features two USB ports, but due to their location they can be comfortably used only to connect keyboard and mouse. Built-in speakers are crap and can only be used for system sounds. Ambient Light Sensor in mine and one reviewed by Overclockers.ru does nothing at all (not a big loss, as I would not use it anyway). Presence sensor mostly works. Touch buttons for menu access have poor responsiveness.

Panel:
Monitor uses AG coating. Coating is not as heavy as on Dell u2312hm and other e-IPS monitors, but crystalline effect is visible if you look close. Display has good panel uniformity, backlight is even, without bleeds.
According to review by Prad.de and at Overclockers.ru panel covers around 99,4% of sRGB color space before calibration and 100% afterwards ( http://www.youtube.com/watch?v=xBDHa7XBIFU ). For those interested in AdobeRGB, it covers around 76% of color space. Viewing angles are as you would expect from MVA based panel (wider than TN but narrower than IPS/PLS). BENQ advertises that 8bit panel is used. I checked Gradient test at Lagom. Gradients were even on default settings, but after calibration you can see banding (I guess it is similar to most 6bit+AFRC IPS displays). Contrast and Black Level tests are perfect after calibration (did not test before). No Black Crush. Every square is visible.

Can not say anything about display responsiveness in games, as I do not play fast paced games. AMA is set on HIGH and I see no problems in general purpose use. According to reviews it is as good as on GW2450HM. Contrast levels are above 3000:1. Brightness can be adjusted from 68 to 260 cd/m2.

PWM:
PWM is used for brightness control. PWM frequency is around 400Hz according to Overclockers.ru and around 360Hz according to Prad.de. PWM can be seen on camera if brightness is reduced below 91%.
The most interesting thing, however, is that I was able to eliminate PWM by setting brightness to 100% and then making ICC profiles for 80 – 140cd/m2 luminance with x-rite i1 Display Pro colorimeter’s i1Profiler software. Display Hardware Setup in i1Profiler is done via ADC, without manual brightness/contrast/RGB levels adjustment. As a result I get heavy contrast loss. Measured contrast is between 1160:1 (80cd/m2) and 2050:1 (140cd/m2). Although much lower than original contrast of >3000:1, those values are still higher than on most IPS/PLS and TN displays.

Average Delta values are between 0.89 and 0.62. Of course LEDs are always on, it results in higher electricity use (I think it is around 40W/h) and shorter backlight lifespan (LEDs are said to last around 11 years if used 6 hours a day).

As a result, I am very pleased with the monitor. I will upload ICC (Mac) and ICM (Windows) profiles for luminance levels between 80 and 140cd/m2 for PWM free use a bit later. Of course they are individual to my monitor, but should give some approximation for people without access to colorimeter.

Here are ICC and ICM profiles:

ICC profiles (Mac OS X) No PWM (settings inside): http://www.4shared.com/zip/unsHF2G0/BL2410PT_noPWM_OSX_.html
ICC profiles (Mac OS X) with PWM (settings inside): http://www.4shared.com/zip/pmwIwhrc/BL2410PT_PWM_OSX_.html
ICM profiles (Windows) No PWM (settings inside): http://www.4shared.com/zip/n4S1e51D/BL2410PT_noPWM_WIN_.html

Will send them to tftcentral.co.uk too.

how is its AG Coating ?

By PRAD.de is very fast for gaming, it is true ?

As I mentioned in my first post, the monitor uses AG Coating, though not as heavy as on Dell u2312hm/u2412m. Crystalline effect is present if you look close. My previous monitor had similar AG Coating, so it is not a problem for me. What's really important, at least for me, is the ability to spend many hours in front of this display without headaches (PWM disabled).
As for gaming, I do game very little and those games I play are not fast paced. I guess you can trust PRAD review in that area, as PRAD seems to be quite reliable.

so its not semi glossy like other VA ?

Are you blind? I already stated for 2 times that it uses AG Coating, PRAD says it uses AG Coating. Should I repeat once again?
And what other *VA monitors are Semi-Glossy? Benq BL2400PT used to be semi-glossy, but starting from 2012 it uses the same panel (with AG Coating) as GW2450HM. The same, as far as I know, applies to newly produced Samsung S24A650D units.

Hi, I've recently purchased this monitor and I got few questions for other users.

I think that gradients are much more visible than on my old TN monitor. It is even visible on Win 7 wallpaper... Even Windows 7 logo on logging when its moving looks weird like it has glow.
I can compare to the situation when colors is set to 16 bit instead of 32 ( little bit less visible)

I see lack of details on black pictures, movies, games, Black is just to dark... and its blurred with no details compared to my old TN

Can anyone share with correct settings of this monitor. I think that it was better when i purchased it maybe i changed smth, but i did factory reset with no success.

EDIT: Its the same on DVI and display Port on integrated and discrete graphic card.

VA panel without very light coating ?mad.gif so epic fail

Try to use profiles I posted above (settings inside).

There is banding on this monitor, but nothing special, similar to most 6bit+AFRC IPS displays.
Regarding Black Crush, try http://www.lagom.nl/lcd-test/black.php test. I can see every single square on mine after calibration.

No perfect monitor exists... Semi glossy would be better, but I am used to AG coating. Had it on previous monitor.
Was considering Asus VG23AH semi glossy IPS, but as with most cheap IPS it has backlight problems, vertical lines due to polarizer, questionable build quality, no portrait mode and low PWM frequencies without possibility to use at 100 brightness due to low contrast. PWM is really a priority for me, as I spend long hours in front of the monitor.
