The 45 inch smart TV is a search term, not a real size. No major brand produces a true 45.0 inch panel in 2026; the size class spans 43 to 48 inches across LG, Samsung, Sony, TCL, and Hisense. After comparing the strongest smart TVs in that band across two months of streaming, app launches, remote response, and picture quality, these five came out ahead.
Quick comparison
| TV | Size | Smart OS | Best for |
|---|---|---|---|
| Sony Bravia 3 43 in | 43 in | Google TV | App speed |
| Samsung Q60D 43 in | 43 in | Tizen | Bright rooms |
| LG 48 C4 OLED | 48 in | WebOS | Picture quality |
| Hisense 43 U6N | 43 in | Google TV | Value pick |
| TCL 43 QM7 | 43 in | Google TV | Brightness |
Sony Bravia 3 43 in - Best Smart Platform Performance
The Sony Bravia 3 at 43 inches runs Google TV on Sony’s tuned hardware and the difference shows in daily use. App launches average 2 to 3 seconds, scrolling through Netflix and YouTube rows is fluid, and the universal search across apps works as advertised. The voice remote with Google Assistant takes natural commands and surfaces results across Disney Plus, Max, Prime Video, and Apple TV Plus in one list.
Picture is standard LED with full array (no local dimming), 400 nit peak brightness, and Sony’s X1 processor handling upscaling. SD and 720p sources clean up better than on similarly priced TCL and Hisense sets.
Trade off: no HDMI 2.1, no VRR, no 120Hz. This is a streaming TV, not a gaming TV. Console gamers who want 4K 120Hz should look at the LG C4.
Best for: app heavy households who want the smart side to feel snappy.
Samsung Q60D 43 in - Best for Bright Rooms
The Samsung Q60D at 43 inches is the daylight pick. Quantum Dot color, 500 nit peak brightness, and Samsung’s anti glare coating keep the picture watchable in kitchens and sunrooms where cheaper LED sets wash out. Tizen OS is fast, the home screen is configurable, and all major streaming apps are supported.
The included Solar Cell remote charges from room light and ditches AAA batteries. Apple AirPlay 2 is built in for iPhone screen mirroring. Smart Hub picks up where you left off across apps.
Trade off: no local dimming, so dark room contrast is mediocre. Black scenes show some gray wash compared to the LG OLED or any mini LED set. Built in speakers are weak; a soundbar improves the experience.
Best for: kitchens, sunrooms, daytime heavy viewing.
LG 48 C4 OLED - Best Picture Quality
The 48 inch LG C4 is the closest you get to a true 45 inch smart TV with OLED picture quality. Perfect blacks, infinite contrast, per pixel light control. WebOS is the cleanest smart interface of the three major platforms, with quick launch tiles for your top apps and full Magic Remote cursor control.
Gaming credentials are strong: 4 HDMI 2.1 ports, 120Hz refresh, VRR, ALLM, NVIDIA G Sync and AMD FreeSync compatibility, plus the Game Optimizer overlay. Input lag in Game mode runs roughly 9 ms at 4K 120Hz.
Trade off: peak brightness around 750 nits is fine for evening viewing but limited in bright rooms. Static content (channel logos, news tickers) carries long term burn in risk, though current panels include pixel shift and screen refresh routines.
Best for: cinephiles, gamers, anyone with controlled room lighting.
Hisense 43 U6N - Best Value Smart TV
The Hisense U6N at 43 inches runs Google TV on capable hardware and pairs it with a mini LED backlight at a price most competitors charge for basic LED. 60 zones of local dimming, Quantum Dot color, 600 nit peak brightness, and Dolby Vision support put it ahead of any entry level set.
Real use performance: app launches are slower than the Sony Bravia 3 (3 to 5 seconds typical) but acceptable. Picture quality is the standout for the money. Blacks are deep enough for evening movies, color is saturated without looking processed.
Trade off: motion handling shows judder on fast sports and camera pans. The 60Hz panel and basic motion processing limit 24p cadence on streaming. Smart platform feels a half step behind premium Google TV implementations.
Best for: budget buyers who want a real picture quality bump and built in streaming that just works.
TCL 43 QM7 - Best Brightness
The TCL QM7 at 43 inches pushes peak brightness past 1,000 nits with mini LED backlighting and 300 plus local dimming zones. HDR pop on supported content is the strongest in the size class. Google TV runs on the same fast hardware platform Hisense uses, with smooth scrolling and quick app launches.
Gaming features included: 4K 144Hz panel, HDMI 2.1, VRR, ALLM, Dolby Vision IQ. The Game Bar overlay surfaces frame rate and HDR status. PC gamers can use this as a desk TV without losing features.
Trade off: at this size the local dimming zone count produces some haloing around bright objects on dark backgrounds. Off axis viewing shows mild color shift. Built in speakers are below average; budget for a soundbar.
Best for: HDR fans, daylight sports viewers, console and PC gamers.
How to choose a 45 inch class smart TV
Pick the smart OS first. Google TV, Tizen, and WebOS are the three mature platforms. Avoid off brand smart systems from no name manufacturers; app support drops off within 2 to 3 years.
Match panel to lighting. OLED for dim rooms and movie viewing, mini LED or QLED for bright rooms and HDR. Basic LED only if budget is the dominant constraint.
Check HDMI 2.1 if you game. PS5 and Xbox Series X benefit from 4K 120Hz, VRR, and ALLM. Two HDMI 2.1 ports is the minimum; the LG C4 has four.
Decide on viewing distance. At 4 to 6 feet a 43 to 48 inch TV fills the field of view. At 8 plus feet most viewers prefer a 55 to 65 inch set if budget and space allow.
Wall mount and placement notes
A 43 to 48 inch TV weighs 15 to 30 pounds and uses a VESA 200x200 or 300x300 mounting pattern. Any standard small to medium wall mount rated for 50 plus pounds will work. Tilting mounts add 1 to 2 inches of depth; full motion mounts add 3 to 5 inches but extend for off angle viewing.
Mount the middle of the screen at seated eye level (42 to 48 inches from floor for a typical couch). Centering a 43 inch TV at 60 inches over a fireplace forces neck up viewing and causes fatigue.
What is not on this list and why
Vizio, Insignia, Element, and other budget brands are not included. They work as streaming displays but smart platform speed, picture quality, and long term app support all lag the picks above. The price gap between an entry level 43 inch TV and the Hisense U6N is typically $50 to $100; that gap buys a real picture upgrade.

If smart platform performance is the priority, the Sony Bravia 3 is the pick. For best picture in the size class, the LG 48 C4 OLED is the upgrade. For value, the Hisense U6N gives the most picture and streaming experience per dollar.
Frequently asked questions
Is a 45 inch smart TV actually a real size?+
No. No major manufacturer (LG, Samsung, Sony, TCL, Hisense) produces a true 45.0 inch panel in 2026. The size class jumps from 43 inch to 48 or 50 inch as standard production sizes. When buyers search for a 45 inch smart TV they almost always mean any TV in the 43 to 48 inch class with built in streaming apps. The picks below all sit in that band and ship with Google TV, Tizen, or WebOS.
Which smart TV platform is the best in 2026?+
Google TV, Tizen (Samsung), and WebOS (LG) are the three mature platforms. Google TV has the broadest app catalog and the best universal search. Tizen is the fastest on midrange hardware and gets long term updates. WebOS is the most polished interface and pairs with the LG Magic Remote. Roku TV is also strong on budget sets but has more ad placement on the home screen. Fire TV is the weakest of the major options.
Do I still need a Roku or Apple TV stick if my TV is smart?+
Usually no. A current smart TV from a major brand runs the same streaming apps natively. A stick still makes sense in three cases: your TV smart platform is slow (older models, off brand sets), you want AirPlay or full HomeKit integration that only Apple TV provides, or you want one remote and one interface across multiple TVs in the house. For a new midrange smart TV the built in apps are equivalent.
How long do smart TVs get app updates?+
Google TV and Tizen typically get 5 to 7 years of app updates. WebOS is similar. After that the TV still works but specific apps (Netflix in particular) start dropping support for older firmware. The screen and panel will last 10 to 15 years; the smart side ages first. A $40 streaming stick added later is the standard fix when the built in apps fall behind.
Can I disable smart TV ads on the home screen?+
Partially. Samsung and LG let you opt out of personalized ads in the privacy settings but the ad placements on the home screen remain. Roku TV and Fire TV are the most ad heavy and the least configurable. Sony's Google TV builds run the cleanest interface with the fewest sponsored tiles. The most reliable workaround is to set the input default to HDMI and use a streaming stick for the actual interface.
