Smart TV Buying Guide – Why It’s Tricky To Buy?

Purchasing a smart TV could be tricky because of the misleading marketing campaigns and lack of consumer knowledge.

There are certain TV features that you should prioritize over others and carefully consider options, based on factors such as the living space, budget, and requirements.

So, let’s walk you through the top 10 mistakes when buying a smart TV.

Top 10 Smart TV Buying Mistakes to Avoid

Smart TVs are your path to immense movie nights, immersive gaming, and streaming in your living room, but a wrong selection can leave you frustrated. 

With endless TV brands, specs, and features to look through, it’s easy to get misled by a tricky marketing strategy or miss crucial details. 

Many buyers regret their choice within months due to issues like wrong sizing or incompatible features, so let’s break down the top 10 Smart TV buying mistakes to avoid.

Starting with the most important…

1. Getting the Wrong Size

A TV that’s too large overwhelms your view, not to mention eye strain, especially if your room is too small.

While a smart TV that’s too small makes details hard to see, going for the largest TV screen available is not always the right choice.

At ZontSound, we recommend choosing a screen size based on your viewing distance!

For 4K Smart TVs, the best distance is ~2 times the screen size in inches (e.g., a 55-inch TV is best viewed from 5–6 feet).

Hence, measure your room and reposition furniture placement to ensure the smart TV fits perfectly within the recommended distance.

Recommended TV Sizes by Viewing Distance
Screen Size (Inches)	Idea Distance (4K)	Room Size (Typical)	Best For
32–40	3–5 feet	Small (e.g., bedroom, kitchen)	Solo viewing, small spaces
43–50	4–6.5 feet	Medium (e.g., apartment living room)	Couples, small families
55–65	5–8 feet	Medium-large (e.g., standard living room)	Family movie nights, gaming
75–85	7–10 feet	Large (e.g., spacious living room, home theater)	Large gatherings, immersive setups
85+	10+ feet	Very large (e.g., dedicated media room)	Cinematic experiences, premium setups

Quick Tip: Use an online TV size calculator or project the TV dimensions on your wall to visualize the position and viewing experience.

2. Buying a Smart TV Online 

Buying a smart TV online might feel fast and convenient, but skipping on research can backfire sooner than you think.

You could end up with a low-quality set, missing key smart features, or a refurbished unit sold as new, so you need to watch out for a few critical aspects before buying.

Before clicking “buy,” verify the TV’s specs:

Also, don’t put all your trust in reviews that claim that a certain TV model has “great visuals.”

The picture quality varies based on your own tastes, the lighting in your room, and the type of shows or movies you watch.

Hence, the best recommendation here is to see the TV in person.

Quick Tip: Only buy from reputable online retailers like Amazon, Best Buy, or Walmart with clear return windows (at least 30 days).

3. Overlooking the System (OS)

A slow or unsupported operating system can make navigating apps, device compatibility, and streaming frustrating, turning your movie nights into a nightmare.

So, knowing which operating systems to choose is key when buying a Smart TV.

Below are the most popular Smart TV operating systems:

We strongly recommend avoiding anything beyond the list above. This is, of course, if you are looking for a long-term smart TV solution.

4. Ignoring Picture Quality Factors

Compromising on picture quality leads to dull colors, blurry images, or weak contrast, ruining the fun of movies, gaming, and shows, especially on bigger screens. 

So, focus on essentials like resolution, HDR, and panel type!

Look for 4K resolution, HDR10+ or Dolby Vision, and a premium panel like OLED or QLED in the TV’s specs.

Visit a store to compare brightness and color differences, and check reviews for reliable performance insights. 

Here’s a quick description of all key Smart TV features:

Smart TV Picture Quality Essentials
Feature	Description	Importance	Recommendation
Resolution	Determines image sharpness	Higher resolution delivers clearer details.	Choose 4K for most setups; avoid 1080p for TVs over 40 inches
HDR (High Dynamic Range)	Enhances color, contrast, and brightness	Makes visuals more lifelike with deeper blacks and whites.	Look for HDR10+ or Dolby Vision for superior performance
Panel Type	The display technology (e.g., LED, QLED, OLED)	Affects color accuracy, contrast, and viewing angles	OLED for perfect blacks and wide angles; QLED for bright rooms
Brightness	Measured in nits, impacts visibility in bright rooms	Higher brightness ensures clear images.	Aim for 500+ nits for bright rooms, 1000+ for premium models
Color Accuracy	How true-to-life colors appear	Accurate colors enhance realism for movies and games	Seek 90%+ DCI-P3 coverage for vibrant, realistic visuals

Quick Tip: If you want the best possible smart TV experience, go for a 4K TV with HDR10+ and an OLED/QLED panel.

5. Skipping Connectivity Options

Insufficient or outdated connectivity options can limit your smart TV’s ability to connect gaming consoles, soundbars, or streaming devices.

A TV without all the necessary wireless or physical connections may also struggle with smart home integration or other high-quality streaming units. 

At ZontSound, we recommend ensuring your Smart TV has a variety of modern wireless and physical connectivity options to support current and future devices. 

Here are the essential wireless/physical connections you need to consider:

Wireless Connectivity

Physical Connectivity

• ✔️HDMI 2.1 (3+ ports): Handles 4K/120Hz, eARC for soundbars, and gaming perks like VRR and ALLM.
• ✔️USB (2+ ports): Great for external drives, media playback, or powering streaming devices.
• ✔️Optical Audio Out: Links to older soundbars or receivers for clear digital sound.
• ✔️AUX (3.5mm): Connects wired headphones or speakers, though rare on newer models.
• ✔️RCA (Composite): Works with old-school devices like DVD players, but is less relevant today.

Tip: Prioritize the TV features that you’ll be using the most.

6. Neglecting TV’s Sound Quality

A lot of Smart TVs come with weak built-in speakers that sound tinny or flat, making dialogue hard to hear and music feel lifeless.

Well, this can muffle your movie nights or gaming sessions, pushing you to spend extra on a soundbar sooner than expected.

Check the TV’s audio specs, like speaker wattage (aim for 20W+ for decent sound) and support for Dolby Atmos or DTS for immersive audio.

Listen to demo units in-store if possible, and read reviews.

If the TV’s audio is lacking, consider a soundbar or speakers within your initial budget.

Quick Tip: Prioritize TVs with Dolby Atmos or plan to pair a budget soundbar for richer sound.

7. Not Checking Brand Reliability

Choosing a lesser-known or untested brand might save money upfront, but poor build quality or limited updates can lead to regrets. 

So, stick to established brands with a proven track record for quality, longevity, and responsive support.

Research brands on popular websites, check user reviews for real-world reliability, and verify warranty terms (at least 1–2 years). 

Here are some smart TV brands you can’t go wrong with:

• Samsung
• LG
• Sony
• TCL
• Hisense
• Vizio
• Panasonic
• Philips

Quick Tip: Choose a brand with a 4+ star rating on trusted review sites for peace of mind.

8. Buying During the Wrong Period

Purchasing a Smart TV outside major sales events means missing out on significant discounts, sometimes up to 30–50% off, leaving you paying hundreds more for the same model.

Impulsive purchases can cost you big, while waiting for discounts gives more time for planning/checking.

Time your purchase for major sales like Black Friday or Amazon Prime Day, when retailers offer deep discounts on Smart TVs. 

Quick Tip: Plan for Black Friday sales in late November for the best TV deals!

9. Paying for Extended Warranty

Smart TV extended warranties often cost $50–$200 but may cover problems already included in the manufacturer’s standard warranty or issues that rarely occur.

This extra expense can bubble up your smart TV cost unnecessarily, so we recommend avoiding it.

Skip extended warranties unless you’re buying a high-end model and need extra peace of mind, and check if your credit card offers free warranty extensions.

Quick Tip: Save money by relying on the standard warranty for the most reliable TV brands!

10. Purchasing an (8K) Smart TV

In 2025, 8K TVs remain prohibitively expensive, often costing $2,000 or more, yet the lack of widely available 8K content makes their superior resolution largely unused. 

Spending on an 8K model often means sacrificing premium 4K TVs with very good features like OLED panels, high refresh rates, or advanced HDR, which offer a better viewing experience.

At ZontSound, we advise sticking to high-quality 4K TVs, which are more affordable (starting at $500–$1,500) and supported by abundant 4K content.

Compare specs to ensure you get a 4K TV with Dolby Vision, 120Hz refresh rates, or OLED technology instead of an entry-level 8K TV.

Quick Tip: Invest in a premium 4K TV for vibrant visuals and save thousands over an 8K model.

Key Smart TV Features to Prioritize

To get the most out of a smart TV for the budget you’ve got, focus on features that ensure your performance and stay relevant for years. 

Here are all the essential features you should prioritize:

• 4K Resolution
• HDR10+ or Dolby Vision
• Reliable OS
• HDMI 2.1 (3+ ports)
• Wi-Fi 6
• OLED or QLED Panel

• 💲If you’re on a budget, prioritize 4K resolution and a good system over extras like 120Hz refresh rates, which matter more for gamers. 

• 💲💲For mid-range or premium models ($500–$1,500), aim for OLED/QLED and HDR10+ to elevate your experience. 

Budget vs. Premium Feature Comparison
	Budget ($300–$500)	Mid-Range ($500–$1,000)	Premium ($1,000+)
Resolution	4K	4K	4K (avoid 8K)
HDR	HDR10	HDR10+ or Dolby Vision	Dolby Vision
Panel Type	LED	QLED or Mini-LED	OLED or QLED
Refresh Rate	60Hz	60–120Hz	120Hz
OS	Roku, Android TV	Roku, webOS, Tizen	webOS, Tizen
Connectivity	2–3 HDMI, Wi-Fi 5	3+ HDMI 2.1, Wi-Fi 6	4+ HDMI 2.1, Wi-Fi 6

Note: Stick to these priorities, and you’ll get a Smart TV that performs great without wasting money on overhyped extras.

Smart TV Red Flags to Watch Out For?

When buying a smart TV, certain warnings can save you from a very bad deal or a disappointing purchase.

Spotting these smart TV red flags can instantly help you make better choices for your long-term investment, so let’s learn how to recognize suspicious patterns in smart TV marketing.

• Very Low Prices: A 55-inch 4K TV for $200 from an unknown seller is likely low-quality, refurbished, or a scam.
• Missing TV Specs: Listings that don’t mention resolution, HDR, or OS details often hide subpar features.
• Unknown Brands: Unfamiliar brands with no reviews or track record may lack durability or support.
• No TV Warranty: A warranty under one year or missing altogether signals poor reliability.
• No Return Policies: Retailers with strict or unclear return terms make it hard to fix a bad purchase.

Important: At ZontSound, we strongly recommend purchasing smart TVs without a warranty!

So, take time to research specs, compare models, and shop smart during sales to get the absolute best deal possible.
