What is the best 40 inch smart TV to buy?
Top 40‑inch smart TVs of 2026
Though true 40‑inch screens have all but vanished, several 42‑ and 43‑inch models serve the same purpose. TechRadar (consumer tech authority) names the LG C5 42‑inch OLED as the overall best pick, citing its brightness boost over the C4 and extensive gaming features. For budget buyers, the Amazon Fire TV Omni QLED 43‑inch is the recommended value choice.
RTINGS.com (dedicated TV lab testers) gives the LG OLED42C5PUA its top rating, praising perfect black levels and self‑lit pixels. The LG C4 remains a viable, slightly cheaper alternative.
LG’s OLED42C5PUA proves that small‑screen buyers no longer have to compromise on picture quality. The trade‑off is a higher price tag — around $1,300 — compared to LED alternatives that cost half as much.
Key features to compare
- Resolution: Full HD vs 4K — 4K is increasingly common and noticeable at close viewing distances (TechRadar).
- Smart platform: Tizen (Samsung), webOS (LG), Fire TV (Amazon), Android TV.
- Panel type: OLED (best contrast), QLED (brighter), LED (budget).
Price‑to‑performance ratio
The best value today sits in the $300–$500 range for a quality 43‑inch 4K model. For Irish buyers, Euronics Ireland (national electronics chain) highlights the LG OLED AI 55‑inch as premium, but 43‑inch options from Samsung and Hisense offer similar features for less.
The pattern: small‑screen buyers now have a clear premium‑value split.
How much is a 40 inch smart TV Samsung?
Samsung 40‑inch TV price tiers
Samsung no longer produces a true 40‑inch model; its smallest smart TVs start at 43‑inch. The Samsung 43T5300 (1080p, Tizen) typically retails for around $330 in the U.S. and €290–€350 in Ireland, according to stock listings at Expert.ie.
For a 4K Samsung, the 43AU9000 is priced near $480 in U.S. markets. Irish prices tend to be slightly higher due to VAT — expect €450–€550 from Euronics Ireland.
Where to buy (Ireland‑focused)
- Euronics Ireland — stocks Samsung 43‑inch models with nationwide delivery.
- Expert.ie — offers Samsung 43‑inch smart TVs with price‑match guarantees.
Factors affecting price
Resolution (1080p vs 4K), panel type (LED vs QLED), and smart platform features drive most price differences. Sales and bundle deals can reduce costs by 10–20%.
The catch: true 40‑inch Samsungs are gone, so adjust room planning.
Which is better, a 40 or 43‑inch TV?
Size difference in real‑world use
A 43‑inch screen provides roughly 15% more viewing area than a 40‑inch. RTINGS.com notes that 43‑inch models now dominate the market, offering better 4K availability and more features at similar price points.
Viewing distance and room size
For a viewing distance of 6–8 feet (typical bedroom or small living room), a 43‑inch TV works well. At 5 feet, a 40‑inch can suffice but the 43‑inch still feels comfortable. TechRadar suggests 43‑inch is the new minimum for a satisfying experience.
Resolution impact at each size
On a 40‑inch screen, the difference between 1080p and 4K is subtle beyond 8 feet. At 43‑inch, 4K becomes more perceptible, especially for text and HDR content. Most 43‑inch models now ship with 4K as standard, while many older 40‑inch sets stuck to Full HD.
If your space is extremely tight (under 6 feet), a 40‑inch still works. But you’ll pay a “rarity premium” — 40‑inch models are becoming harder to find and often cost more than comparable 43‑inch sets. RTINGS.com advises buying 43‑inch for better value and selection.
What this means: 43‑inch is the pragmatic choice for most rooms.
Which is better Samsung TV or LG TV?
Smart platform comparison: Tizen vs webOS
TechRadar judges webOS (LG) as more intuitive, with a cleaner interface, while Tizen (Samsung) offers a broader app library. Both platforms receive regular updates.
Picture quality and color accuracy
At the 40–43‑inch level, Samsung typically produces brighter panels, thanks to its QLED technology. LG counters with superior contrast and black levels in its OLED models, though those are not available at 40‑inch. RTINGS.com notes that LG’s 42‑inch OLED (C5) outperforms any Samsung of equivalent size in contrast.
Value and warranty
Samsung offers longer panels warranties (2 years standard) in many markets, while LG usually provides 1 year except on premium OLEDs. In Ireland, both brands are widely available at Euronics and Expert.ie.
The implication: your choice hinges on how much you value contrast vs brightness.
What is the lifespan of a 40‑inch smart TV?
Average lifespan and what affects it
Most 40–43‑inch LED TVs last 5–7 years with moderate use. TechRadar reports that power surges, heat, and humidity are the main failure triggers. OLED panels (like the LG C5) have a shorter half‑life in terms of brightness degradation — about 4–6 years before noticeable dimming.
LED vs QLED vs OLED longevity
- LED: 5–7 years, most reliable at this size.
- QLED: 6–8 years, better brightness longevity.
- OLED: 4–6 years before burn‑in risk increases, but pixel‑refresher technology helps.
Warranty and maintenance
Samsung and LG offer standard 1–2 year warranties. Extended warranties through retailers like Expert.ie can add coverage for up to 5 years.
The pattern: LED remains the longevity champion for this size.
Which is better, 4K or QLED?
Resolution (4K) vs color technology (QLED)
4K refers to 3840×2160 pixels; QLED is a display technology that uses quantum dots to boost brightness and color volume. TechRadar explains they are not mutually exclusive — many 4K TVs also use QLED. For small screens, 4K matters most at close viewing distances (under 5 feet).
Which matters more on a 40‑inch screen
At typical bedroom distances (6–8 feet), the jump from 1080p to 4K is modest. QLED’s wider color gamut and higher peak brightness improve HDR content regardless of resolution. RTINGS.com says for a 43‑inch set, prioritise 4K over QLED if you watch 4K sources; otherwise, QLED gives a more vibrant picture.
Price impact
A 4K‑only TV (e.g., Samsung 43AU9000) costs around $480. A 4K QLED model (e.g., Amazon Fire TV Omni QLED 43‑inch) adds roughly $100–$150 for better color.
The catch: you rarely need both unless you watch HDR frequently.
Comparison Table: 40‑inch vs 43‑inch at a glance
Three key factors, one clear trend: 43‑inch has become the new 40‑inch.
| Feature | 40‑inch | 43‑inch |
|---|---|---|
| Availability | Nearly discontinued (RTINGS.com) | Widely available |
| 4K UHD models | Rare | Common |
| Average price (2026) | $280–$400 (few models) | $250–$500 |
| Best for | Ultra‑small spaces under 6 ft | Bedrooms, dens, small living rooms |
The pattern is clear: 43-inch has become the new default for small spaces.
Specifications Table
Below are the essential specs for a typical 2026 40–43‑inch smart TV, sourced from TechRadar and RTINGS.com.
| Specification | Value |
|---|---|
| Resolution | Full HD (1080p) or 4K UHD |
| Refresh rate | 60 Hz (most models) |
| Panel type | LED, QLED, or OLED (LG C5) |
| Smart OS | Tizen, webOS, Fire TV, Android TV |
| HDR support | HDR10, HLG; Dolby Vision on premium |
| HDMI ports | 2–3 (HDMI 2.0 typical) |
| Wi‑Fi | 802.11ac (Wi‑Fi 5) or 802.11ax (Wi‑Fi 6) |
| Weight | 7–10 kg (without stand) |
These specifications show that 40-43 inch TVs now offer features once reserved for larger screens.
Pros and Cons of 40‑inch Smart TVs
Upsides
- Compact size fits small rooms and wall mounts easily (TechRadar)
- Lower power consumption than larger sets
- Affordable entry point for smart TV features
Downsides
- Very few 40‑inch models remain; 43‑inch is the new standard (RTINGS.com)
- 4K less noticeable at typical viewing distances
- Premium panel tech (e.g., QLED, OLED) less available at 40‑inch
The trade-offs highlight the importance of measuring your space before buying.
What We Know vs What’s Unclear
Confirmed facts
- 40‑inch smart TVs are widely available from Samsung, LG, Hisense, TCL (RTINGS.com)
- Full HD is standard; 4K is increasingly common at higher price points (TechRadar)
- Samsung and LG offer the most robust smart platforms (TechRadar)
What’s unclear
- Whether QLED will become standard at 40‑inch or remain premium‑only
- Exact future model availability in Ireland
- Long‑term reliability differences between LED and QLED at this screen size
What’s clear is that the market has shifted away from true 40-inch models.
Expert Perspectives
“The LG C5 42‑inch OLED is the best 42‑inch TV we’ve tested, offering perfect black levels and exceptional gaming features.”
RTINGS.com (TV testing lab)
“For budget buyers, the Amazon Fire TV Omni QLED 43‑inch is the top choice — it balances price, picture quality, and smart features better than any other small TV.”
TechRadar (consumer tech authority)
For Irish buyers, the consensus from both Euronics Ireland and Expert.ie is clear: 43‑inch has replaced 40‑inch as the small‑room standard. The real choice is between a value 43‑inch LED for €300–€400 or a premium 42‑inch OLED for around €1,200.
The implication: if you’re shopping for a 40‑inch TV in 2026, your options are very limited. The pattern is to buy a 43‑inch set instead — you’ll get better value, wider selection, and future‑proof 4K. The catch is that the extra inch may feel large in a tight space, but most users adjust quickly.

Frequently asked questions
Is a 40-inch TV too small for a living room?
For a typical living room with a viewing distance of 8–10 feet, a 40‑inch screen is on the smaller side. A 43‑inch or 50‑inch is more appropriate. However, for a small living room or apartment where you sit closer, 40‑inch can work.
Can I use a 40-inch TV as a computer monitor?
Yes, but screen resolution matters. A 4K 40‑inch TV offers a usable desktop experience; a 1080p model will show pixelated text. Ensure the TV supports PC‑friendly refresh rates (60 Hz is fine for office work).
Do 40-inch TVs support HDR?
Many 40–43‑inch 4K models support HDR10 and HLG. Dolby Vision is less common at this size. TechRadar notes that HDR performance on budget models is often underwhelming due to low peak brightness.
What is the refresh rate of most 40-inch smart TVs?
The vast majority use a 60 Hz panel, even 4K models. 120 Hz is rare at this size and usually reserved for gaming‑focused TVs in larger diagonals.
Are there 40-inch OLED TVs?
No true 40‑inch OLED TV exists. LG makes a 42‑inch OLED (C5), which is the closest option. OLED at this size is premium‑only.
Which brand offers the best warranty on 40-inch TVs?
Samsung generally offers a 2‑year warranty in many markets; LG provides 1 year standard, with extended plans available. Retailers like Expert.ie sell extended 5‑year cover.
Should I buy a 40-inch TV in 2026?
Only if you have an extremely tight space (under 6 feet) and find a good deal on a remaining 40‑inch model. Otherwise, buy a 43‑inch 4K smart TV — it offers better value and will serve you longer. RTINGS.com echoes this advice.
How much does a 40-inch smart TV cost in Ireland?
Prices in Ireland for 43‑inch models start at around €280 for a budget Full HD set and go up to €500 for a 4K model from Samsung or LG. Premium 42‑inch OLEDs (LG C5) cost about €1,200. Check Euronics Ireland and Expert.ie for current deals.
