Contact your dealer. If it is a manufacturing defect, BenQ will replace it with a new one. However, if it was caused by the user, you may ask the dealer to ship it back to our service centre, and you or your dealer will be charged for the repair.

Referring to the commercial standard of an LCD panel, when a single spot is over 50%, it is regarded as one spot (Red, Green and Blue Rule 1); when two adjacent spots are RG/GB/BR and are over 50%, the max. is 3 dark and 7 bright in the same screen (Rule 2). Please refer to API RGB LCD PANEL SPEC.

Please visit the BenQ website at www.BenQ-eu.com/serviceandsupport/ to download the appropriate LCD Monitor drivers, alternatively you can also use the standard plug n play monitor driver in windows.

Strange lines appear on an LCD panel under very few circumstances. It may be a result of the VGA signal and can be corrected by the adjustment menu on the monitor. In the adjustment menu choose geometry setup and you can adjust the horizontal or vertical phase and pixel frequency.

The FP 551 uses Hosiden Panel. Due to the fact that the original manufacturer design of the Hosiden Panel driving current is limited to 5mA, when the contrast is too high, a change in the brightness is not apparent. After having conferred with Hosiden, the driving current range has been modified to a larger margin and the change in brightness will become noticeable after adjustment. In order to achieve a noticeable change in brightness, we recommend the following: Adjust Contrast to optimal range around 25~35, then adjust Brightness. There will be a distinct change in brightness.

Check the pins of the connector, if there are any bent or missing pins, contact your dealer. You can also either check the settings of your VGA card or whether or not the display frequency you are using is within the limits of the monitor.

Go into the Control Panels, and select "reset factory preset timings", or any default factor value from the table.

Check the energy saving mode; press any key or move the mouse to quit the energy saving mode. Check if there are any bent or missing pins in the monitor connector. If there are, contact your dealer.

The so-called response time refers to the time it takes for a liquid crystal panel to go from total white to total black and then back again (Rise Time (Tr) + Fall Time (Tf)). Broadly speaking, the response time of LCDs are slower than those of CRTs. In the past, the response time of most LCDs was between 20ms and 50ms, and the adverse effects of this relatively long interval could be noticed during playback of DVDs or when playing games that required especially quick scene changes. You would, for example, find that fast-moving objects would cause ghosting, particularly when black objects passed through a bright-colored background.

Image frequency and the human eye

The human eye will perceive a series of sequential images displayed at a frequency of 30Hz (30 images, or frames, per second) as continuous, as is the case with movies (24 frames per second). Screen images displayed at 60Hz will offer even more comfortable viewing, but careful scrutiny will reveal a slight sense of "flickering", as is the case with the NTSC television standard (which displays at 60 frames per second). According to standards set by VESA (Video Electronics Standards Association), the frequency necessary to achieve flicker-free display with a CRT is 72Hz. Most VGA cards and software applications, in order to accommodate the use of CRT monitors, have working frequencies set at 75Hz. In the past, the LCD monitors with 16ms response time that predominated in the market supported frequencies only up to 63Hz (1/0.016), making their display performance inferior to that of CRT monitors. Avid gamers therefore continued to use CRT monitors.

Lightning fast response time: 12ms

BenQ's new FP767-12 and FP783 LCD monitors represent a breakthrough, having reduced response time to a mere 12ms. The LCD panels used in them can support a display frequency of 83Hz (1/0.012). Coupled with BenQ's sophisticated electronic design, this allows BenQ's LCD monitors to achieve the full performance potential of their hardware, enabling them to fully support the 75Hz working frequency of VGA cards, as well as their targeted applications. The amazingly fast 12ms response time made possible by BenQ LCD monitors provide exceptionally fluid video without flickering and other visual artifacts. The result is that dynamic game and movie scenes displayed at 75 frames per second appear without breaks, offering display quality fully the equal of a CRT monitor's.



Gaming

Today's most popular games-whether racing titles such as 2 Fast 2 Furious, first-person shooters like Half-Life: Counter-Strike or Unreal Tournament 2, or sports games such as NBA Live 2004-demand speed and fast responses. Taking 2 Fast 2 Furious as an example, if your LCD's response time is slightly slow, you may notice a momentary blurring of the track or even a double-image of your racecar when you accelerate to shoot past another racer. Not only is the visual experience of the game marred, but these effects may even lead to a mistake in driving judgment that could mean the difference between victory and defeat.

Moreover, when you are playing a first-person shooter game such as Counter-Strike, if the time between discovery of an enemy combatant and firing your weapon is delayed by even milliseconds, it can mean the difference between survival or adding yourself to the bodycount. Smart gamers know the advantage of having an LCD monitor with a fast response time. And BenQ's 12ms response time give you that crucial edge at the moment of truth!
