Severe vertical banding on multiple OLED TVs.
Severe vertical banding on OLED TVs.

Goal

The goal of this test bench is to add a new test to evaluate TVs for the presence of vertical banding. This issue is very common on OLED TVs, which struggle to maintain even black levels in very dark scenes. You can see a few examples of this in the photo above. These photos were captured on recent OLED TVs, and as you can see, there are very noticeable vertical bars on all of them. This can be extremely distracting when watching dark scenes in a dark room.

The size, visibility, and number of bands vary from unit to unit, so the goal of these new tests is to objectively measure and quantify the amount of vertical banding visible on each TV.

What's New In 2.4

  • Added a new "Vertical Banding" section.
    • Added a new 5% gray test photo.
    • Added a new "Vertical Banding Visibility" test.
    • Added a new "Vertical Banding Contrast" test.

We are retesting popular models first. So far, the test results for the following models have been converted to the new testing methodology. However, the text might be inconsistent with the new results.
