There's also a rare third panel type, the TN panel. On average, VA and IPS panels have about the same black uniformity, but it depends on the model. ![]() The more common IPS panels have a low contrast ratio, which we can see with the ASUS TUF Gaming VG27AQL1A above. VA panels are known for their high contrast ratio, so they display deep blacks, but it doesn't mean they have good black uniformity, as seen with the AOC CQ27G2 in the When It Matters section. Most monitors use LCD panels, of which there are different types. Monitors use different panel technologies to produce an image. This leads to certain areas of the screen having stronger backlight than others which leads to very visible uniformity issues in blacks but also colors and greys.īlack uniformity with different panel types Uneven intensity of the lighting. Sometimes, the LEDs themselves have manufacturing issues.These can cause uneven diffusion of light which leads to clouding and backlight bleed. When the monitor is being built or transported, some of these layers likely bend. Lenient manufacturing and uneven frames. LCD screens are made of many layers, and most of these are flexible.Learn more about different types of backlights on TVs here. However, some higher-end monitors have direct LED backlighting with LEDs placed all over the screen, resulting in better uniformity. Unfortunately, not all of these designs are made the same, and edge-type backlights will often have a visible backlight that looks like a distracting bright strip on one of the edges of the screen. Many monitors only have a strip of LEDs at the top or bottom of the screen and use a series of diffusion films behind the LCD panel to create an even backlight. The position and quality of these backlight systems have an impact on the uniformity of the screen. Poorly designed backlight. LED-backlit LCD monitors require a backlight to show the image on the screen.Additional Information What causes backlight bleed and clouding? Backlight bleed and clouding can occur for a few reasons: ![]()
