Calculating the Size of a Screen Bezel
To calculate the size of a screen bezel in pixels from millimeters, you must multiply the screen width/height in pixels by the bezel size in millimeters, then divide by the screen width/height in millimeters.
For example, given:
- A 2×2 four panel display wall (see Image 1)
- The dimensions of each panel are1100mm x 620mm
- 1100 mm = 1920 pixels and 620mm = 1080 pixels
- The vertical bezel is 17mm and the horizontal bezel is 20
the number of pixels in the vertical bezel area is (1920 x 17) / 1100 = 30 pixels and the number of pixels in the horizontal bezel area is (1080 x 20) / 620 = 35 pixels. Add the width (1920p + 30p + 1920p) to the height (1080p + 35p + 1080p) to get the total bezel-adjusted resolution (3870 x 2195 pixels).

Configuring a Video Wall with Bezel Compensation
To configure a 1x2 video wall with bezel compensation:
vm = CreateObject("roVideoMode") sm = vm.GetScreenModes() sm[0].video_mode = "1920x1080x60p" sm[0].transform = "normal" sm[0].display_x = 0 sm[0].display_y = 0 sm[0].enabled = true sm[1].video_mode = "1920x1080x60p" sm[1].transform = "normal" sm[1].display_x = 0 sm[1].display_y = 1100 'Bezel compensation of 20 pixels sm[1].enabled = true sm[2].enabled = "false" sm[3].enabled = "false" vm.SetScreenModes(sm)
