See it right with Matrox Bezel Displacement

Designed for digital signage professionals, Matrox Bezel Displacement provides image compensation for the physical border of display bezels. Images on multi-display, stretched desktop setups may look elongated or disproportioned because the image stops at the end of one screen and begins on the next. The distortion is caused by the physical space created by the bezels located between each pair of screens.

Matrox Bezel Displacement adjusts the display areas so images and text appear to pass behind the bezels. The feature allows you to adjust the image to compensate for the physical space between screens created by various bezel sizes.		 Matrox Bezel Displacement

Using Matrox Bezel Displacement
Bezel Displacement is a feature of Matrox PowerDesk 2.04-SE (and above) display driver software. Once PowerDesk is successfully installed, you can access the feature by clicking the PowerDesk icon (Matrox PowerDesk-SE icon) on your Windows taskbar.¹

Example: Setting up a 2x2 display configuration:
1. From the Bezel Displacement dialog box, click on the display to be adjusted. A square appears within the selected display and all effected displays are highlighted in green.

Display 4 is selected for a vertical bezel adjustment.
Since the change affects Display 3, it is also highlighted in green.
2. Use the adjustment options to increase the vertical and/or horizontal seams, either in pixels, or as a percentage of the selected display. As the adjustment is made for particular seam, two diagonal lines move and adjust to form a perfectly aligned "X".
Monitor Bezels are not properly aligned
Before the display seam is adjusted, "X" is not aligned.

The total resolution of the desktop is enlarged to compensate
for the pixels that are beneath the display bezels.
3. Monitors come in all shape and sizes, so different displays require different adjustments. When you are happy with the results, click OK to accept the changes, and the system is ready to go.

Note: In this example, after Bezel Displacement has been adjusted, the new effective resolution is 2650x1626. Content should now be designed for this enlarged resolution, or make sure your application allows content to scale to the new resolution.
