OSD Setup And Calibration Of The XL2430T
OSD Tour
The XL2430T’s OSD is just like every other BenQ monitor we’ve tested: full-featured and efficient. Pressing any bezel key or the wheel on the S Switch brings up a small menu.
The top three slots can be programmed for many quick-access functions. Above you can see how the menu looks from the factory. We changed the third one from Display Mode to Brightness, making it easier to adjust the backlight when using Blur Reduction. Clicking Menu brings up the full OSD.
There is a lot here. Fortunately, it’s logically grouped into four sub-menus, the first of which contains gaming settings.
The big star is of course Blur Reduction. If you use it with an HDMI source, it’s either on or off, resulting in an 81-percent brightness reduction. You get a pulse-width adjustment called Intensity over DVI and DisplayPort, along with an Area slider.
At the default setting of 10, Intensity causes only a 51-percent light reduction, which can be easily compensated for by turning up the backlight. You can run Intensity up to 25, but then you’re looking at 96 percent less light output.
The Area slider is something we haven’t seen before. It is intended to selectively reduce blur depending on image content. In our tests, it only seemed to cause tearing and jitter artifacts when turned up too high. It comes set to 10, and that's where it works well.
Black eQualizer tweaks low-end gamma to help improve contrast. Since it starts at zero, it also crushes detail if you increase more than a little.
Color Vibrance increases saturation and may satisfy some users. Colors look more vivid, though the feature can also cause a loss of image detail.
Low BlueLight is a feature found on most BenQ monitors. It reduces blue and warms the image to reduce eye fatigue. Using the Standard picture mode already gets you pretty close to D65, so we recommend leaving this one alone.
Instant Mode increases the pixel clock to improve response. We enabled it for all our tests.
Auto Game Mode applies different enhancement settings depending on content. If you want consistency between games, it’s best to leave this off.
Save Settings lets you preserve the game options to one of three memory slots. They can then be called up using the three buttons on the S Switch. If you change any picture settings in the next menu, they apply globally.
All of the calibration adjustments are in the Picture menu. You get eight image modes – three for FPS and RTS games, three memories for custom gaming settings plus Movie and Standard. Our favorite is Standard, which is very accurate out of the box and can be tweaked for even better performance.
AMA is another tool to help improve the panel’s response time. We set it on High for our tests.
Dynamic Contrast improves perceived contrast at the expense of a skewed gamma curve. If you don’t mind sacrificing a little detail, it can be used sparingly.
There are five gamma presets, and the fifth option is best. The others are all too light and create a somewhat dull image. Regardless of the other options you choose, we recommend Gamma 5 for all content.
Here are the RGB sliders. They are available in the gaming modes as well, but they are most effective in Standard. You won’t need to change them much to achieve excellent grayscale tracking. The Normal, Bluish and Reddish presets are fixed and can’t be adjusted.
The Display menu contains the input selector and a few other options.
Display Mode refers to image sizing. Full represents a 1:1 pixel map for incoming signals. The other options size the image to match different game screens. This is a great way to avoid distorted images in older titles designed for 4:3 monitors.
HDMI RGB PC Range comes set to levels 16-235, which is incorrect. Change it to 0-255 for proper compatibility with PC signals. If you use DisplayPort or DVI, the option is grayed-out and the XL2430T handles PC-range content correctly.
Overscan is useful when watching TV broadcasts full-screen. You can use it to remove garbage pixels from edges of the image.
The final menu, System, has OSD options, languages, signal info and a factory reset option.
Customkeys refer to the top three bezel control buttons. They can be set to a variety of monitor functions, saving you a trip to the OSD when making quick changes.
Signal info gives you the active input, plus incoming and outgoing resolution, along with refresh rate.
The Other Setting menu has little-used options like on-screen notices. The main one to be concerned with is DDC/CI. Leave it on so the monitor can communicate with your PC.
Calibration
Once we switched to the Standard picture mode, our work was largely done. Tweaking the RGB sliders and setting the gamma to preset five produced a great image, yielding excellent test results. It’s easy to maintain contrast post-calibration thanks to a control that allows some upward adjustment. We could raise it to 52 before any clipping occurred. Sharpness works just fine at level five. Any higher and obvious edge enhancement appears, which actually reduces the clarity of small fonts and objects.
