On displays with Full-Array Local Dimming (FALD), blooming (also referred to as halo effect) occurs when the light that’s illuminating a small object bleeds into the surrounding dimmed zones.
Just how bad the blooming is depends on the number of dimming zones the monitor has and how demanding the displayed scene is.

How To Reduce Blooming On Tv
Unlike OLED displays which are self-emissive, LED monitors and TVs rely on a backlight to produce the picture.
This means that LED-backlit displays cannot produce true blacks and that some light will always bleed/pass through the panel thus resulting in backlight bleeding or VA/IPS glow depending on the panel type.
In order to bring the image quality of LED displays closer to that of OLEDs, some manufacturers implement localized dimming in their monitors and TVs. While this technology does help with the picture quality, it’s not perfect.
What Is Local Dimming?
Most LED displays use global dimming where the entire picture gets darker with dark scenes – or brighter with bright scenes. In short, there’s no localized dimming which is why you get such limited contrast ratio with this type of displays.
Next, there are edge-lit displays which have several dimming zones at either top/bottom or left/right side of the screen.
While these displays can increase the contrast ratio a bit, there won’t be any improvement in scenes in which there are a lot of dark and bright details close to each other due to the limited number of dimming zones.
In scenes where the contrasting elements appear far from each other, the picture quality won’t be ideal either as vertical or horizontal banding can occur. In other words, edge-lit local dimming is not very effective except in some rare scenes.
With full-array local dimming solutions, LEDs are placed across the entire screen behind the panel for a much better control of dimming zones according to the displayed content.
However, FALD displays are also considerably more expensive and bulkier in design.
FALD: Pros and Cons
Besides the heftier design and price tag, FALD displays can also exhibit blooming in certain scenarios.
If you have a small bright object, such as a cursor, on a plain dark background, some light from the cursor will bleed into the surrounding dimmed zones and create the halo/bloom effect that will follow your cursor as you move it.
Of course, local dimming wasn’t designed for regular desktop use, so in video games and movies, this will be much less noticeable. You can simply disable local dimming when not watching videos or playing games.
Depending on the number and size of dimming zones, some blooming can also be visible in certain scenes in games and movies too – but in all except for the most extreme cases, it’ll be negligible.
In the near future, manufacturers will turn to Mini LEDs which allow for additional dimming zones.
The PG27UQ with a 384-zone FALD solution, for instance, will be available as the PG27UQX with 576 Mini LED dimming zones which should reduce the amount of visible blooming by 33%!
While still not perfect, these FALD displays do offer the best HDR image quality possible on gaming monitors, at least until OLED and MicroLED gaming monitors become available.

Believe it or not, despite the fact that your Smart TV is HD ready, it might not be configured to stream HD the second you take it out of the box. Always take a minute to go into your display settings, and make sure the display is configured for the right TV size.
It’s a small action that could make a world of difference when it comes to enjoying video content on your new TV.

17. More Apps: Use Sideloading to Unlock Previously Unavailable Apps
Both Amazon Fire and Google Chromecast allow users to sideload apps, meaning they can be installed manually through the smart plug-in. The biggest benefit to this is that often you can access apps that are not available on your mobile devices.
Many region-blocked apps are available through sideloading, so it’s worth checking out what new options are available to download through your Smart system.

To access a broader range of apps, you can install Aptoide TV. Aptoide hosts a lot of apps that are blocked by bigger, mainstream providers, so it’s worth checking out their selection.
20. Switch Accounts: Add Other IDs to Your Apple TV
If you’re living with a family or lots of roommates, there’s an easier way to share the Apple TV. Just go to settings, click accounts, and then click “iTunes and App Store”.
From here you can switch accounts, so that other people’s purchases and downloads aren’t associated with your account.

Did you know you could create, edit, and share Microsoft documents from your Smart TV? There are a number of Microsoft Office apps that are free to download in the Google Play store, that will allow you to work from the comfort of your sofa.
Just search and download from your phone, and get your work done on your TV.
