If you are looking for a 45-inch smart TV, start by measuring the space—not by assuming a TV’s diagonal size equals its width. The compact recommendations and listings reviewed here center on 40-, 42-, and 43-inch sets; a 45-inch model may be uncommon among them, but that does not establish that none exist. If those nearby sizes could fit, compare specific 43-inch 4K smart TVs such as the Samsung U7900F and LG QNED70A, then verify dimensions, features, local availability, and price for the exact model sold in your country.
How to find the right size when you want a 45-inch TV
TV size refers to the screen’s diagonal measurement, not the television’s outside width. A set described as 43 inches can be substantially narrower than its diagonal measurement, and its frame and stand affect the space it needs. Measure the intended location, then check the manufacturer’s dimensions for the exact model, including width, height, and stand depth. For wall installation, also check mounting dimensions and clearance.
The available compact-TV recommendations and category listings reviewed for this guide focus on 40-, 42-, and 43-inch televisions. That is a description of those sources, not proof that 45-inch TVs are unavailable everywhere. If a model’s label or listing looks suitable, confirm its actual dimensions and regional SKU before buying.

| Model | What the manufacturer identifies | What to verify before purchase |
|---|---|---|
| Samsung U7900F, UN43U7900FFXZA | Samsung US identifies this as a 2025 43-inch Class Crystal UHD 4K Smart TV. Its US page displayed $329.99 and showed delivery and store pickup unavailable when accessed; those are dated page details, not a current or universal price or stock guarantee. | Check the exact US listing or local equivalent for current price, stock, dimensions, apps, warranty, and supported features. Samsung U7900F product page |
| LG QNED70A, 43QNED70AUA | LG USA identifies this as a 2025 43-inch Class 4K Smart TV. That confirms the model identity and class, not how its picture or overall performance compares with another TV. | Check the exact SKU sold in your country for dimensions, apps, inputs, warranty, availability, and features. LG QNED70A product page |
| TCL 43-inch models | TCL’s global category page lists multiple 43-inch TVs. It describes features including 4K, QLED, HDR, HDMI, USB, Wi-Fi, and Bluetooth across the category; not every model necessarily includes every feature. | Use the local product page for the exact model to confirm its panel, HDR formats, inputs, wireless features, and dimensions.

For broader compact-size comparisons, RTINGS’ guide to 40-, 42-, and 43-inch TVs says its recommendations consider price, visitor feedback, and availability. What Hi-Fi?’s compact-TV guide discusses panel type, brightness, platform, and use cases. Rankings and recommendations on review sites can change; treat them as inputs to your decision, not as results of testing performed for this guide.
What to compare before choosing a compact smart TV
Fit the set to the room or cabinet
- Measure the usable width, height, and depth of the space, allowing for the TV frame, feet or stand, cables, and ventilation clearance.
- Compare those measurements with the manufacturer’s dimensions for the exact SKU. Do not infer width from the screen’s diagonal size.
- For a wall-mounted TV, confirm the model’s VESA pattern, weight, mounting instructions, and clearance. Check that the wall and mount can support the set; a mount must match the specific TV.
Match the picture to your lighting and seating
Compare the display type and evidence about contrast, brightness, reflection handling, and viewing angle. A bright room with windows may make reflection handling and brightness especially important; off-center seating can make viewing angle matter more. Check which HDR formats the exact model supports rather than assuming that all TVs labeled 4K or HDR behave alike.

Confirm the streaming platform works where you live
Check that the TV’s operating system has the apps you use in your country. App availability and product variants can differ by region. Consider whether the manufacturer’s software-support policy meets your expectations, and look for details that apply to the exact model rather than relying on a family name alone.

Check gaming features and HDMI inputs
If you use a game console, compare the TV’s native refresh rate, supported variable-refresh features, HDMI input count, and each input’s capabilities with what the console can use. A feature listed for a product family may not be available on every size or regional SKU, so confirm it on the exact model page or in its manual.

Decide whether the built-in sound is enough
Consider how clearly the built-in speakers will serve your room and viewing distance. Add a soundbar only if it addresses a real need, such as dialogue clarity or fuller sound; it is not a prerequisite for buying a smart TV.
Compare the whole purchase, not just the listed price
Check local stock, delivery, warranty, return policy, and support alongside the current price. These terms and availability can change quickly, and US product pages do not establish what a buyer will receive in another market.

Energy figures need a model and reporting period
The CTA/D+R table reports 164 kWh annual energy consumption for the Hisense 43A6H for televisions sold by signatories between April 1, 2024 and March 31, 2025. It is a model-specific figure for that reporting period, not an estimate for the Samsung or LG examples above and not a typical value for all 43-inch TVs. CTA/D+R television energy-consumption report
