The good news is that TV has come a long way in the last few years! Technological advancements, along with the enormous growth of on-demand services like Netflix or Amazon Prime, allow for incredible visuals from the comfort of our own home.

With a rise in streaming services that release whole seasons of shows in one go, binging TV is becoming the norm. There can be nothing worse than experiencing technical issues or poor screen quality when you’re halfway through the latest season of Stranger Things or The Crown (and these shows deserve to be seen at their best!).

However, there’s no need to fret when it comes to achieving amazing picture quality; we can help!

Here, we lay out some of the most common issues behind poor picture quality and the ways you can solve them, so you can continue your Netflix binge or movie marathon in peace!

Channel Picture Quality Below TV Standard

This point only really applies to people who have purchased high-end TVs, such as 4K or even 8K resolutions. If you have a new fancy TV system and are disappointed that the quality is poor, then double-check the definition of your programme. 

The streaming service Disney Plus hosts an abundance of 4K content which should show up beautifully on newer 4K TVs, provided there aren’t any other technical issues at play!

Unadjusted TV Settings

If you are experiencing difficulties with general screen quality and not TV resolution, you might want to take a look at your system settings. Playing around with picture settings, brightness and colour controls can help you produce a clearer picture to suit your needs. After all, watching the latest Marvel movies in fully adjusted HD is always a must!

Bad Cable Connections

One of the most common causes of bad picture quality is unsecured or poorly connected cables. This may sound like a simple fix (and it can be), but there are a plethora of cables that might be causing your issues! Understanding the functions of each cable can help when it comes to getting the best screen quality.

Another frequent cause of broken picture quality at home is interference. These days, our homes are a complex system of electrical wires that can sometimes disturb each other. In an emerging world of wireless and connected smart devices, there are now almost innumerable things that could cause interference.

Electrical Interference on Freeview TV

If your Freeview TV continues to break up at specific points in the day, particularly during the evening, this could be caused by electrical interference. Anything that consumes significant amounts of electricity when in use, such as appliances, pumps and some heating systems, could be causing fluctuations in your signal.

To remedy this situation, try to keep your aerial and other cables as separated from other electrics as possible. While this can be hard, even a little bit can make a difference and prevent an annoying pixelated picture.

Interference on Digital Cable or Internet-based TV

As with electrics, internet connectivity can be impacted by interference from both in and outside the home. 

If you rely on broadband to watch TV, then a reduced internet speed can cause some irritating issues with picture quality. Buffering or lagging screens can be the bane of any viewer’s watching experience.  

To reduce these effects, it can help to remove all other connected devices in the vicinity of your television. Turning them off completely and giving the TV access to as much broadband as needed can help restore your picture quality in no time.

Unaligned Aerial/Satellite

Bad weather can be a nuisance at the best of times, but when it starts to mess with your TV signal, there’s nothing worse! Storms pass, but signal issues can remain. If your picture’s not up to scratch after a bout of rain or strong wind, it could be that the weather has disturbed the alignment of your aerial or satellite.

Unalignment issues can be hard to spot with the naked eye (unless the satellite or aerial is dislodged), so consider speaking to a trained engineer if you think this might be the problem.
