How to Fix a Vizio TV That Is Too Dark

Why is my Vizio TV darker than usual?

The main reason why a Vizio TV is darker than usual is because of backlight issues, auto brightness levels are too low, ambient light sensors or auto dimming and dimming zone settings.

Some Vizio TVs will have issues when the image is not displayed on full screen or when the screen dims. This can be irritating and bothersome, detracting from enjoying a good TV show or a fast-paced game.

If you’ve been experiencing similar problems, this page provides the reasons and remedies for each of these problems.

A dim screen is triggered by a hardware problem or image settings that adjust the display automatically.


The following features will cause your display to darken. Remember that your TV offers only one or a few options.

  • Controlling the Backlight
  • Controlling the brightness automatically
  • The sensor of Ambient Light
  • Luma Adaptive
  • Automatic Dimming
  • Dimming Zones

Another dimming source appears when the TV activates the HDR option. This is an HDMI-specific function that occurs when 4K material is shown. This will be consistent throughout your 4K experience.


How to fix a Vizio TV screen that is too dark?

To fix your Vizio TV screen that is too dark you need to find the proper input settings for the specific model of TV you’re using.

This information varies greatly between models. In most circumstances, the procedures in this section will be sufficient to return your Vizio TV to regular operation and eliminate the screen that is too dark.

OK, this one may seem strange initially, but stay with us as we explain why. If you are using your Vizio without a DVR, this may have a detrimental impact on the image quality.

This is because a DVR will efficiently simplify and refine the streaming. As a result, if you have a DVR, we recommend hooking it up and trying the TV again. In a few circumstances, this will completely cure the problem. Whether it hasn’t, we’ll need to look at your settings to determine if they’re the source of the problem.


Though unlikely to generate big black areas on the screen, incorrect screen settings can cause significant chaos. We’ve even encountered settings that resulted in clouding, which is exactly what it sounds like So, we’ll need to check the settings you’ve got in place to ensure they’re not too much out of whack


  • Too much brightness may be an issue in the room where the TV is located, especially if you also utilize high contrast levels. It might also make sense to experiment with lowering the brightness intensity


Because not everyone knows how to change the brightness, here is the technique.

  • The first menu you must access is the “settings” menu. You will now browse to the “image settings” option. You will be able to reach the setting required to lower the brightness level from this menu
  • While doing so, we recommend lowering the level in increments and checking back to see whether the desired impact has been achieved


Faulty Sensors

Unfortunately, if none of the preceding solutions worked, there is a significant likelihood that the problem is too serious about being resolved from the comfort of your own home. Nothing has worked so far suggests that the light sensors have begun to malfunction.

The objective of these sensors is to feed the image to the screen while maintaining great sharp quality. Of course, they need to be checked or changed every now and again.


Input Issues

Let us merely deal with the physical inputs. So all you have to do is swap out the wires that connect to the TV. If any of these are damaged (or get too old), they can begin to produce more and more havoc until they eventually fail.

If all of the inputs and connections were good, we’re afraid you’ll need to reference the manual to locate the suitable input settings for the specific model of TV you’re using.

How to fix a Vizio TV HDR that is too dark?

To fix a Vizio TV HDR that is too dark, you can watch TV in a dimmer lit room or disable HDR from the TV Settings.

The movies and TV shows you’ve been viewing for years have been mastered in what’s now known as standard dynamic range, or SDR—and it’s pretty dull, with peak brightness levels of only approximately 100 nits.

On the other hand, most current LCD TVs can produce 300 nits or more when playing SDR video, so if you’re in a brilliantly lit room, turn up the Backlight, which raises the brightness of everything in the Picture—from dark shadows to dazzling highlights.

If you can’t achieve a bright enough HDR picture in your sunlight living room, go to your streaming box’s menu, choose display settings, and disable HDR. In rare cases, you may always return to HDR mode.
