    Toshiba M450

    This is a fantastic 43” TV. I bought one for my son a while back to use with his new XBOX series X. Of course, a high end monitor is best when playing video games but, this TV suffices and gives the UHD video quality something to admire. The refresh rate is the only downside. But for general TV watching, it’s worth the money. He’s had the TV for several years and it’s still working great. Recently, I needed another TV for a different room and found it on sale for basically half price and bought two for $169 each. The built in Fire TV works well. The picture quality is great. The sound is good as can be with internal speakers. The TV turns on quickly. I’d pay the typical price which is $320 for this TV. Toshiba is an underrated brand that is actually the most popular in Japan. You can’t go wrong purchasing this TV.

    Great under rated QLED 4K TV for the price

    Perfect size TV for my garage gym. I have only had this 43" Toshiba TV a month. Picture quality is crisp and clean. The sound is effortlessly bold and powerful. Amazon fire tv works as expected activated and organized all apps needed. This was a great purchase for what I need it to do.

    A great buy at a great price!

    Only had a few weeks but so far I am very impressed with this TV! The sound is good and the picture is great! It fits perfect on my dresser in bedroom. Replaced an old Roku (never again) TV. Don’t need my old soundbar either, it sounds great without. A Best Buy at Best Buy!

  • Will this TV work with an old-school roof antenna?

    Hello Russ, thanks for your question. Yes, the Toshiba 43" M450 QLED Fire TV (43M450SU) will work with an old‑school roof antenna, and it’s fully compatible as long as the antenna uses a standard coaxial cable connection, which plugs directly into the TV’s built‑in over‑the‑air tuner so you can scan for local channels.
