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.

Would recommend this tv
I recently upgraded to the Insignia Fire TV 4K, and it has completely changed the way I enjoy movies, shows, and games at home. For the price, this TV delivers incredible value—sharp 4K resolution, vibrant colors with HDR support, and the convenience of Amazon’s Fire TV built right in. What I love most is the built-in Fire TV platform. No extra devices needed—apps like Netflix, Prime Video, Disney+, and YouTube are ready to go from the start. The Alexa voice remote makes it effortless to search for shows, adjust volume, or even control smart home devices. It feels futuristic but simple. The picture quality is crisp and clear, perfect for sports and movies. While the sound is decent, I paired mine with a soundbar for an even better experience. Setup was quick, and the interface is smooth and intuitive. Pros • Affordable entry into 4K smart TVs • Fire TV integration = endless streaming options • Alexa voice control adds convenience • Multiple HDMI ports for gaming and devices • Built-in speakers are average (soundbar recommended) • Picture quality is great, but premium models offer deeper blacks. The Insignia Fire TV 4K is a budget-friendly powerhouse. It’s perfect for everyday viewing, family entertainment, and casual gaming. If you want a smart TV that’s easy to use, packed with features, and won’t break the bank, this one is a winner.

The Price is always right at Bestbuy
For the past 10 years, I have bought 13 televisions from Bestbuy.com, for my home in both Miami and the USVirgin Islands; and, 10 of those tv's have been Insignia smart televisions. The other 3 brands were Sony, Toshiba & LG. Of those other 3 brands, I find LG, to be going strong. Thus far it is up and performing well in my 4 years of owning it. Sony & Toshiba both lasted 2 years. They died the exact time the quarantee expired; picture tube issue. So instead of replacing with the same item, I just bought Insignia tv. I have found that Insignia, out performs and out last those other well known brands. It's as if I was paying for their presigious name and not the workmanship of their product. Insignia television Picture Quality is Excellent. The cost is fairly cheap and affordable. The life span for Insignia is 7 to 8 years, before they start to malfunction. But for the low cost in buying one, "I can say that I had gotten more than my moneys worth, of prestine quality television. When they fail, I just discard the tv in the dump, and go out, and buy another new and updated, smart Insignia TV. I only buy "new" unused products.
