Choosing among TVs & display panels usually comes down to a tension: do you want OLED, Mini-LED, a very large screen, or the lowest listed price? These four choices separate those priorities across different sizes, conditions, and feature sets. Start with the job the screen must do-everyday streaming, a home theater, or a connection-heavy setup-then use panel type, screen size, condition, and price to narrow the field.
Quick take
- Insignia F50 Series: the lower-price route for everyday viewing.
- Samsung M70H: the connection-focused route with gaming-related features.
The seller page may include additional marketing claims. Treat this page as a shopping reference, then confirm fit, price, delivery, and returns on the seller page.
- TCL QM8K: the large-screen home theater route.
These are distinct buying priorities rather than one universal answer. The best fit depends on which specification matters most in your room.
Listed price comparison
| Product | Listed price | Price bar |
|---|---|---|
| Insignia F50 Series LED Smart Fire TV | $179.99 | |
| Samsung M70H Mini LED HDR Smart TV | $334.60 | |
| LG OLED55B4PUA OLED Smart TV | $517.50 | |
| TCL QM8K Mini-LED Smart TV | $2,391.04 |
The listed prices span from $179.99 to $2,391.04, an absolute spread of $2,211.05. That gap makes it especially important to decide whether your priority is panel type, screen scale, condition, or the purchase price itself.
Decision matrix
- Panel: LG is the OLED-named model; Samsung and TCL carry Mini-LED in their names; Insignia is an LED model.
- Scale: the listed screen sizes are Samsung 43 inches, Insignia 50-inch class, LG 55 inches, and TCL 98 inches. Use those dimensions to match the room rather than treating size as a picture-quality ranking.
- Condition: Insignia is new, Samsung is open box, LG is used, and TCL is certified refurbished.
- Motion figure: Samsung lists 60 Hz, while TCL lists 120 Hz. Treat those as fit criteria without assuming that the higher number automatically determines picture quality.
Product notes
Samsung M70H
Samsung M70H suits a setup that needs several connection types alongside 4K viewing. Bluetooth, Digital Audio Optical TOSLINK, HDMI, and USB are included, while the feature set adds Game Mode, Voice Search, Wi-Fi Ready, Local Dimming, HDR TV, and a remote control. Tizen, Samsung TV Plus, and Gaming Hub also give it a clear smart-TV and gaming-use brief. The concrete limitation is its open-box condition, which may matter to shoppers who want a new set. Choose Samsung when connection variety and gaming-oriented features matter more than moving to a larger screen.
TCL QM8K
TCL QM8K is aimed at a large-screen home theater use case. It carries a 98-inch screen, 4K resolution, HDR, HDMI, and a 120 Hz refresh rate, with QD-MINI LED picture technology also called out. That creates a clear panel-and-scale brief for shoppers planning around the screen itself. The concrete limitation is its Certified - Refurbished condition, which may rule it out for someone prioritizing a new set. Its listed price also sits at the top of this comparison, so this model makes sense when screen scale leads the decision. For a different room footprint or condition preference, the other three models point elsewhere.
LG OLED55B4PUA
LG OLED55B4PUA is a 4K HDR smart TV with Wi-Fi Ready, Voice Search, a voice remote, Wide View Angle, Thin Bezel, and a 2 Port USB Hub. HDMI and Digital Audio Optical TOSLINK support an audio/video connection plan, while Picture in Picture and Sports Mode add further viewing features. Its concrete limitation is the used condition, so it is not the match for someone who wants the new-condition route. The listed price sits above Samsung and Insignia in the comparison, making OLED the defining reason to select it rather than the lower end of the range. Choose LG for OLED and voice-focused controls.
Insignia F50 Series
Insignia F50 Series is the straightforward lower-price route, with a new condition and a 50-inch-class LED 4K UHD Smart Fire TV format. HDR10 and DTS Virtual-X audio accompany over-the-air channels, Fire TV access, and Alexa voice control. A manufacturer warranty and 4K maximum resolution round out its everyday-entertainment brief. The limitation is the LED panel, so shoppers who have already decided on OLED or Mini-LED should move to the LG, Samsung, or TCL model instead. Select Insignia when new condition and the lower end of the price range outweigh specialty-panel priorities.
Final recommendation by use case
- Lower listed price with new condition: Insignia F50 Series.
- A connection-focused setup: Samsung M70H.
- OLED as the non-negotiable panel type: LG OLED55B4PUA.
- A large-screen home theater: TCL QM8K.
Choose one priority first, then let the remaining differences settle the decision. Panel type, screen scale, condition, and price each point to a different fit across these four 4K smart TVs.
