It didn’t take long into our Toshiba 43LF621U19 43-inch 4K Ultra HD Smart LED HDR TV review before we realized it’s one of the most impressive cheap 43-Inch TVs we have ever reviewed. It’s one of those electronic devices that remind you to never judge a book by its cover.
Toshiba 43LF621U19 43-inch 4K Ultra HD Smart LED HDR TV review part 1: What’s in the box of this cheap 43 inch TV?
The exterior of the 43LF621U19 is rather plain, with a plastic bezel surrounding the screen that is just as ordinary. The infrared receiver that receives input from the remote is located at the lower right corner of the front area.
It comes with two plastic TV stands that look just like what you would find when you take a close look at any budget TV. It a very stable stand, but it won’t impress anyone. It gets the job done, which is what matters.
There are three HDMI ports located at the back of the TV, an optical audio output connector and a USB port. It also comes with an RCA video input, cable/antenna connectors and an Ethernet port. The input/power button is also located at the back of the television.
The Toshiba 43LF621U19 43-inch 4K Ultra HD Smart LED HDR TV comes with an Amazon Fire TV remote that is somewhat similar to what comes with Fire TV streamers. It comes with three menu buttons that are located above the navigation pad and three playback buttons below. At the top of the remote, you’ll find the microphone and power buttons.
It also comes with a live TV button, volume rocker, mute button and dedicated buttons for popular streaming services like PlayStation, Netflix, HBO, or Amazon Prime Video. The remote communicates with the TV via Bluetooth and infrared signals.
Alexa and Fire TV OS

You can also effortless stream from any other streaming services like Hulu or HBO. During our Toshiba 43LF621U19 43-inch 4K Ultra HD Smart LED HDR TV review, we noticed it also comes with a YouTube app, but we were never able to get it to work unless we opened up the site using the Firefox web browser that comes with this Smart TV.

Toshiba 43LF621U19 43-inch 4K Ultra HD Smart LED HDR TV review part 2: High resolution, decent colors and mediocre contrast
The Toshiba 43LF621U19 43-inch 4K Ultra HD Smart LED HDR TV has an above-average peak brightness of 352.8cd/m2, a not so impressive 0.2cd/m2 black level, and dismal 1,764: 1 contrast ratio.

The Toshiba 43LF621U19 43-inch 4K Ultra HD Smart LED HDR TV performs exactly as you would expect a budget TV to perform. There’s a reason why high-end TVs like the Samsung NU8000 55 Inch 4K Smart TV cost over $2,000!
Power Consumption and input lag
A TVs input lag is how long it takes for the picture to update after it gets a signal. While watching movies, the input lag on this television is quite poor at 70.6ms.

The 43LF621U19 consumes 137 watts and it does not come with a power-saving feature.
