REVIEW: BenQ G2411HD Part 14

DVD film "The Lord of the Rings: The Fellowship of the Ring".

The image quality for film playback confirms our impressions from the gaming test: The lack of light patches, a good black value and high contrast ensure very good film playback. Streaking is hardly visible in video playback. On the other hand the monitor loses points for the viewing angle, which makes a DVD evening with more than three viewers impossible.

DVD series: "Two and a Half Man: My cool Uncle Charlie".

Video signal processing

BenQ itself does not provide any details regarding what input signals and refresh rates are supported. It is also unknown what electronics are used. In the following procedure, we tested to what extent the G2411HD is suited for the playback of external sources other than the PC as a video processor.

Supported refresh rates

Since displays with frequencies other than the usual 60 Hertz are very rare in the PC sector, we do not expect miracles in terms of refresh rates for an office model. Frequencies of 50 Hertz or multiples of 24 are especially helpful in allowing for judder-free display of videos and films. In order to test whether the monitor can also work internally with these frequencies, we carried out a juddering test.

Juddering test on the G2411HD

More information can be found in our special "Perfect image enjoyment: It depend on the image frequency!".

Full-HD with the usual frequencies of 60 and 50 Hertz.

The G2411HD surprised us with possible playback of 50 Hertz as well as the usual frequency of 60 Hz. Thus, even the judder-free playback of 50i material, such as that on German PAL DVDs, is possible. Frequencies of 70, 72 and 75 Hertz could also be selected in a maximum resolution of 1.280 x 960. Through judder-free testing of 72 Hertz – a multiple of 24 – we also hoped for 24p playback of Blu-rays. Unfortunately, the G2411HD responded to the playback of such material with a black screen. Nonetheless: Playback, if somewhat juddery of Blu-rays is possible with a resolution of 1080p at 60 Hz.

Also surprising, but unusable, was the fact that we could also force a frequency of 56 Hertz in the driver, which the G2411HD even displays without juddering. The possible resolution in this frequency was limited to 800 x 600 pixels.
