OSD Setup And Calibration
OSD Tour
The BL3201PT’s menu system is large, but logically organized. It will be familiar to users of BenQ products.
Pressing any button on the bezel or OSD controller brings up a little menu. The first three positions can be programmed by the user for settings like brightness, contrast or picture mode. The fourth button opens the full menu.
First up are the input selector, Auto Pivot (on or off) and PIP/PBP functions. You can view two sources at once either side-by-side or windowed.
Here’s where you’ll find most of the image controls. One caveat, though. If you want full adjustability, you have to select the User picture mode from the Picture Advanced menu first.
Brightness and Contrast are available in every mode. Sharpness comes set to level 5 and should be left there for the clearest image.
There are five gamma presets, but only number three tracks 2.2. The other settings make the picture darker or lighter in the mid-tones. Set to three, however, we measured some of the best gamma numbers we’ve seen to date.
A trio of preset color temps are available, along with a User Define mode. The sliders start at their max values, which means that any adjustment will reduce contrast slightly. Luckily, they don’t need too much tweaking to achieve excellent accuracy.
The next sub-menu, Picture Advanced, is where you’ll find the 11 picture modes. Standard, sRGB and User are pretty much the same, according to our measurements. If you want the BL3201PT’s maximum light output, choose Presentation. The other modes are optimized by BenQ to be better-suited to different tasks. Using any of them is a matter of personal preference as they do not match the Rec.709 or sRGB standards.
The BL3201PT offers 11 different aspect ratio modes. They’re designed to simulate the size and shape of smaller monitors, showing your image windowed. To fill the screen regardless of input resolution, choose Full.
This option is important if you use an HDMI connection. To see the full dynamic range of a PC signal, you have to set it to 0-255. By default, it’s incorrectly set to 16-235. If you use DisplayPort, this option is grayed out and won’t affect the image.
In the Audio menu, you can adjust the speaker/headphone volume or mute the sound. You can also select the source (HDMI, DVI or analog) by choosing Auto Detect.
Custom Key refers to the first three bezel buttons that can be customized for a long list of monitor functions. The two options for DP and HDMI Auto Switch allow you to include or exclude those inputs from the source auto-detect function. We left them both on, and the BL3201PT locked onto the active signal almost immediately every time. If you want to shut the monitor off automatically, you can choose a 10-, 20- or 30-minute delay.
The second screen of System options includes odds and ends like signal information, DisplayPort version and Controller Key choices. Unlike the Custom Key option, the buttons on the OSD puck controller can only be set for different picture modes. If you switch modes often, this can be pretty handy.
The final two menus, Ergonomics and Eco, make use of a bezel-mounted light sensor to adjust image brightness or turn off the BL3201PT automatically when you leave your desk. To enable the grayed-out options, turn on the sensor in the Eco menu.
Here’s where you activate the monitor’s light sensor for the above-mentioned functions. You can also set its sensitivity, which affects the power-off feature.
Calibration
After selecting the User picture mode, we had access to all image adjustments including five gamma presets and a set of RGB sliders for white balance calibration. It didn’t take much to go from good to great in the color accuracy department. The default Standard mode is just fine. It only showed miniscule errors for both color and grayscale. Gamma tracking is superb on preset three, regardless of any other changes to image parameters. The final tweak we made was to lower the Contrast a bit for better white balance at the 100-percent brightness level. Please try our settings below if you don’t have the means to calibrate your BL3201PT.
