How do you measure a TV screen?

The industry standard for measuring a TV screen is diagonally top corner to opposite bottom corner, some people measure the TV across the top which is incorrect.

What is the difference between HD Ready, Full HD and 4K resolution?

So firstly, the resolution on TVs is measured in pixels and is most commonly measured width x height to get the total number of pixels. Most terrestrial TV channels broadcast in 578i and therefore you are unlikely to see much difference in the different resolution TVs if you’re watching a standard TV channel. HD channels such as BBC One HD broadcast in 1080i.

• HD Ready TVs have a maximum resolution of 720p (1366 x 768), this is the now the lowest resolution TV available.
• Full HD which is 1080p (1920 x 1080), as you can see this has slightly more pixels therefore improving picture quality however you will only notice the difference if you connect a device that is playing in Full HD such as a DVD player.
• 4K resolution also known as Ultra HD is the next resolution available currently. This is known as 2160p (3840 x 2160). This has around four times the amount of pixels compared to Full HD so will provide an even crispier picture when there is 4K content being shown on the TV through a Blu-ray player or a streaming service.

What does SMART TV mean?

Many TV’s can now access a range of “online” features such as, YouTube, BBC iPlayer, basic web browsing, social apps and more, along with access to catch up services. Not all units have this feature and please check the item description prior to purchase. You will also require an internet connection in order to access these services.

What is the difference between LED, QLED and OLED screens?

LED and QLED TVs are similar to each other as they each use LCD panels with LED backlights; the only difference is that QLED TVs use a quantum dot layer that allows them to produce a wider range of colours. OLED panels are completely different, as the pixels are self-lit and can turn themselves off when needed, allowing the TV to produce perfect blacks.

Picture quality between different OLED models doesn't differ much, as they each offer similar picture quality. However, picture quality can change a lot between QLED and LED models, and there are even different types of LED-backlit LCD panels that have unique characteristics.

What is the difference between Freeview, Freesat and Freeview Play?

Freeview, Freesat, and Freeview Play are all TV services that offer a variety of channels, including popular UK channels and on-demand content.

Freeview

• A traditional linear TV service that uses an aerial to deliver content. You can receive Freeview channels with a TV set-top box or a TV with a built-in Freeview tuner. Freeview Lite is a cheaper version that offers only the 15 most popular channels.

Freesat

• A satellite alternative to Freeview that offers a similar selection of channels without a subscription. You can access Freeview channels with a Freesat set-top box if you have a satellite dish instead of an aerial. Freesat offers more than 170 standard channels and more than 25 in HD, plus access to on-demand streaming platforms like BBC iPlayer and ITV Hub.

Freeview Play

• The latest version of Freeview that combines linear TV with on-demand and catch-up TV from various broadcasters. Freeview Play is available on Smart TVs and boxes, and offers access to over 60,000 hours of content, 1,500 boxsets, and more than 70 live channels. You can also use Freeview Play to watch shows from the previous week in the EPG, or scroll back through the last seven days to catch up on shows you've missed.

What is HDR?

HDR stands for High Dynamic Range, and it's a technology that can be used in imaging and on TVs to improve the brightness, clarity, and richness of colours.

What is the difference between eMMC, SSD and HDD?

Embedded Multi-Media Cards (eMMC), solid-state drives (SSDs), and hard disk drives (HDDs) are all data storage devices, but they have different features and uses.

eMMC

• An advanced NAND flash memory package that combines flash memory and a flash memory controller on a single silicon die. eMMC is a popular choice for mobile devices like smartphones, tablets, GPS systems, and eReaders. However, some say eMMC has limited capacity, performance enhancements, and read and write speeds. The “embedded” part of the name comes from the fact that the storage is usually soldered directly onto the device's motherboard, so it is not removable nor displaced easily.

SSD

• A non-volatile storage device that uses NAND flash memory to store data. SSDs are often used in laptops, desktops, and tablets, and are considered the successor to HDDs. SSDs are faster than HDDs and have no moving parts, making them more robust and less likely to break. SSDs can connect to the motherboard using SATA (Serial ATA) 3, mSATA, SATA Express, or PCIe interfaces, and can be easily removed and upgraded.

HDD

• A data storage device that is often used when dealing with large file sizes. HDDs transfer data at a slower rate than SSDs, typically between 0.1–1.7 MBps for read and write processes, compared to 50–250 MBps for SSDs.

What is RAM?

RAM is a common computing acronym that stands for random-access memory. Sometimes it's called PC memory or just memory. In essence, RAM is your computer or laptop's short-term memory. It's where the data is stored that your computer processor needs to run your applications and open your files.

The amount of RAM needed depends on how the system is being used. When video editing, for example, it's recommended that a system have at least 16 GB RAM, though more is desirable. For image editing in Photoshop, Adobe recommends a system have at least 8 GB of RAM to run Photoshop Creative Cloud on a Mac. However, if the user is working with multiple applications at the same time, even 8 GB of RAM might not be enough and performance will suffer.

Which is better, AMD Ryzen or Intel Core?

Each offers unique features tailored to different user needs and budgets. While Intel processors are preferred for high-end gaming due to their high clock speeds, Ryzen processors powered laptops are favoured for productivity tasks and versatile builds.

Does the generation of the processor matter?

The processor and chipset's capabilities are often defined by the CPU's generation. As a general rule, the higher the number, the more feature-rich the CPU, with higher core and thread counts, clock speeds, and cache sizes.
