BenQ FP991

BenQ Group used to go under the name of Acer Communications & Multimedia Group. Last year, Acer Group was announced an independent company.

The exterior of the FP911 doesn’t have any memorable features. It has a simple compact case with a silver front panel, large square control buttons in the lower right corner, and a relatively massive base. You can do what you wish with the screen – tilt it, rotate it, turn it upside down.

There are analog D-Sub and digital DVI-D connectors; you switch between them with a gentle press of the Exit button.

The settings menu is attractive and user-friendly. I would say that it is one of the best I have ever seen. The settings of brightness, contrast and auto-adjustment are assigned quick buttons (the latter of them is labeled “i” for some mysterious reason). I can’t say that the settings are excessive, but everything necessary seems to be included.

The Color page offers you four color temperatures: User Preset (manual adjustment), sRGB (by default, corresponds to 6360K on white and 8580K on gray), Reddish (5630K and 7130K) and Bluish (8890K and 12040K). You may guess from the difference between the color temperatures of white and 50% gray that the color curves won’t be perfect. Gray has some blue in itself, which increases its temperature noticeably.

I carried out the tests using the sRGB setting; the color temperature became 6400K on white and 7080K on gray after calibration.

The viewing angles are good, but never perfect. If you look at the screen at an angle of 60 or more degrees, the white color becomes a bit yellowish. This effect is negligible, though, never causing any discomfort at work.

By default, the brightness setting stands on 90% and the contrast on 50%. I’d like to note that these two settings very slightly influence the real screen brightness. To achieve a screen brightness of 100nit, I had to set both sliders to zero.

As I have guessed, the color curves reveal imperfections in the display’s color rendition. Red is down in the middle of the range, while blue is too high. Such defects can only be corrected by color profiles: if you try to reduce the level of blue in the display’s settings menu, the bluish tint will disappear in the middle of the range, but light and dark tones will become reddish.

At low brightness, the situation is overall the same, with blue striking as too high in the middle of the range and red - in the dark tones.

At default settings, the response time conformed to the specified 25ms. At reduced brightness and contrast, we had a considerably higher pixel rise time, the full time being as high as 38ms. This effect is common among the other displays we test today.

This LCD was close to the Acer AL1911 in brightness and contrast ratio measurements. It is natural, since they have exactly the same specified parameters. The brightness of white fell just a little short of 250nit, while the brightness of black was average. It grew a little, to 1nit, at maximum settings only, however, you will hardly ever use the display with these settings.

According to the test results, the BenQ FP991 is much similar to the AL1911 from Acer, showing good, but not exceptional results. The FP991 boasts a few good advantages, though: the digital input and the base that allows the portrait mode.

The color profile for the BenQ FP991 display: fp991.icm.
