Q: Does this work well as a computer monitor
A: Yes, BUT... I am trying to use this as a PC monitor. The device wakes up as a Fire TV every single time it turns on!!! Just stop already. I do not have a need for this to be a TV at all. I have yet to figure out how to make HDMI port 1, 2 or 3 be the default mode upon power up. So if you want to have to switch inputs EVERY SINGLE TIME you turn on this device, go right ahead. Once the device is switched to HDMI input, the screen is nice and sharp and a great image with my Windows 10/11 PC. I am using it in a virtual pinball cabinet.

Excellent Value for the Price!
I’ve been using the Insignia 43" F50 Series 4K Fire TV for a few months now, and I’m very impressed with the overall experience. The picture quality is crisp and vibrant, with great color contrast and smooth motion perfect for movies, sports, and streaming. The built-in Fire TV interface is fast and user-friendly, and Alexa voice control makes it super convenient to search and switch between apps. The sound quality is decent for a TV of this size, though I’d recommend pairing it with a soundbar for a fuller audio experience. Setup was quick and easy everything was ready to go within minutes. Overall, this TV offers excellent performance for its price point. A great choice if you’re looking for a reliable and feature-packed 4K smart TV without spending too much!

Love our new TV from BestBuy.
We love our new Insignia TV. The picture and sound is perfect. It was easy to setup and the TV looks great in our bedroom. We know that Insignia is a great product because we had 2 Insignia TV's in our motorhome and love the picture on both.
