How to Buy the Right TV: Screen Types, Resolution, and What Actually Matters

Shopping for a new television can feel overwhelming. Walk into any store and you’re hit with a wall of buzzwords — OLED, QLED, 4K, 8K, HDR — and none of them come with a plain-English explanation. The truth is, your TV probably already has better specs than most of the content you’re watching on it. In this episode of Tech Talk with Refresh Computers, technician Adam Littlefield breaks down what those labels actually mean, which ones matter for everyday viewers, and why chasing the highest numbers isn’t always worth your money. We also cover cables, Apple’s latest iPhone announcements, and a handy tech tip for making text bigger on any device.

Choosing the Right TV Size

Before you worry about picture quality or fancy features, start with the basics: size. One of the most common regrets people have after buying a TV is that they went too small. For a typical living room, a 55- to 65-inch screen is a solid choice. If you have a large room or plan to mount the TV high on a wall and sit farther back, a 75-inch set might be the way to go.

Measure your space before you buy! A 75-inch TV on a 50-inch entertainment center is going to be a bad time.

LED, QLED, Mini LED, and OLED — What’s the Difference?

Think of these as different “flavors” of screen technology. Each one describes how the panel behind your screen lights up and produces color. Here’s a quick breakdown:

• LED / LCD — The budget-friendly option and perfectly good for 90% of everyday viewing. These screens perform especially well in bright rooms with lots of natural light.
• QLED / Mini LED — A step up from basic LED. These offer better color and contrast, making them a great middle-ground choice. They work wonderfully for streaming services and general entertainment.
• OLED — The premium option. OLED panels produce deep, true blacks and rich, vibrant colors. If you’re building a home theater or you’re a serious movie lover, this is the technology to invest in.

If you’ve ever been to a Dolby Cinema and seen the difference between “black” and “true black” on the screen, that’s exactly what OLED delivers at home.

4K vs. 8K: How Much Resolution Do You Actually Need?

Here’s the honest answer: 4K is the sweet spot for most homes right now. The numbers 4K and 8K refer to the resolution — the number of pixels the screen uses to display an image. More pixels means a sharper picture, but only if the content you’re watching can take advantage of it.

Most cable broadcasts still use 720p or 1080i. Streaming services offer 4K content more regularly, but 8K content is extremely rare and often locked behind premium streaming tiers. On a TV smaller than 65 inches, you won’t even notice a difference between 4K and 8K because the screen simply doesn’t have enough physical space to show the extra detail.

If you’re buying a very large screen (75 inches or more) and want to future-proof your setup, 8K could be worth considering. For everyone else, save your money and stick with 4K.

A Note on HDR

You’ll also see “HDR” on many TV boxes. HDR stands for High Dynamic Range, and it uses software to adjust colors and make the picture look more vibrant. Results can vary — some people love it, while others find it washes out the image. If you’re not happy with how HDR looks, you can usually turn it off in your TV’s settings.

Modern TVs Are Internet TVs

Almost every television sold today is a smart TV. Operating systems like Google TV, Roku, and Fire TV come built in, giving you direct access to streaming apps like Netflix, Hulu, and Disney+. In many cases, you don’t even need a separate streaming device — just connect your TV to the internet and you’re ready to go.

Keep in mind: smart TVs track what you watch to serve you targeted ads. You can disable content tracking in your TV’s settings. Check out our earlier podcast episode on that topic at refreshcomputers.net.

Don’t Forget About Your Cables

Your fancy new TV is only as good as the cables connecting everything together. If you want to play a PlayStation 5 at 4K with a 120Hz refresh rate and pipe the audio through a surround sound system, that old HDMI cable from 2015 might not cut it anymore. Cable standards have evolved to handle more data, and using an outdated or cheap cable is often the first thing that causes problems.

Ethernet cables matter too. If you’re streaming movies and shows on your smart TV, a wired ethernet connection will give you a far more reliable experience than Wi-Fi. No one wants a buffering screen right in the middle of a climactic movie scene.

Got a Drawer Full of Mystery Cables?

If you have a junk drawer stuffed with cables you can’t identify, here’s a practical rule of thumb: if you haven’t used a cable in the last year or two, it’s probably safe to let it go. Cables older than 2016 are likely outdated and won’t support modern devices. You can bring mystery cables to Refresh Computers and the team will help you sort out what’s worth keeping and recycle the rest.

Apple’s iPhone 18 Pro, Pro Max, and the $2,000 Foldable iPhone Duo

Apple’s “Surprise and Shine” event introduced the iPhone 18 Pro and Pro Max at roughly $100 more than last year’s models, putting them in the $1,200 to $1,300 range. That price bump was expected given rising memory and storage costs. What raised eyebrows, however, was Apple’s decision to delay the more budget-friendly iPhone 18, 18e, and iPhone Air until spring — and to raise the prices on existing iPhone 17 models by $100 in the meantime.

The biggest headline was the iPhone Duo, Apple’s first foldable phone. It features a 5.4-inch cover display that unfolds into a 7.6-inch screen — just half an inch smaller than an iPad mini. It’s essentially an iPad in your pocket. But it starts at $2,000 for just 256GB of storage, and it’s eSIM only, meaning there’s no physical SIM card slot.

For comparison, Samsung responded by cutting the price of its similarly sized Galaxy Z Fold 8 to $1,650 — and that model starts at 512GB of storage, double what Apple offers at a lower price.

If you currently have an iPhone 16 or 17 and you’re on a budget, this probably isn’t the time to upgrade. Wait until spring when Apple releases its standard and budget-friendly models — and watch for potential sales when those new devices launch.

Tech Tip: How to Make Text and Screens Bigger on Any Device

This week’s tech tip is one of the most helpful adjustments you can make, and it takes just a minute or two. If you’ve ever squinted at your phone or struggled to read text on your computer, here’s how to fix it:

• iPhone/iPad: Go to Settings → Display & Brightness → Text Size and drag the slider. For even larger text, check the Accessibility settings.
• Android: Go to Settings → Display → Font Size and Display Size and adjust the slider to make both text and icons bigger.
• Windows: Go to Settings → System → Display and change the Scale percentage. You can go up to 200% in the standard options, or up to 500% in Advanced Display Settings.
• Mac: Hold the Command key and tap the plus (+) key to zoom in on any web page.
• Any web browser: Hold Ctrl (Windows) or Command (Mac) and press + to zoom in on the page you’re viewing.

All of these devices also have a Magnifier tool in their Accessibility settings that works like a digital magnifying glass, letting you zoom into specific areas of your screen.
