The Projector isn’t just a standard unit, and it is a little more different than other 4K Projector on the market because it has a built-in Amazon Alexa Voice Control. You can talk to the device and ask it to turn on and off, adjust the speakers, and control your settings.

Amazon Alexa is compatible with Google Assistant that allows you to control the device entirely, as mentioned above.

When it comes to the installation, you won’t have any difficulties while setting it up. Optoma UHD51A Includes an automatic alignment with a vertical lens shift as well as a 1.3 x zoom, which makes it easy to adjust the screen and the resolution for any screen size.

What to Expect From a Cheap 4K Projector?

You shouldn’t expect a cheap projector to use 4K technology. Most of the time, these projectors contain a lower resolution chip in addition to a 4K enhancement technology that allows them to create 4K images on the screen.

The technology typically uses 3 LCD chips each 1920 x 1080p to make up the image. You won’t really notice a big difference in the screen resolution, and you will still end up with a clear image and vibrant colors. However, these projectors have a shorter lamp life than native 4K projectors, and most of them won’t last more than 5000 hours with high energy modes.

How to Pick a 4K Projector

There are some features that you need to pay attention to whenever you are buying a new projector, let’s talk about them briefly.

Brightness

Before buying your projector, consider how bright the image it produces is as well as the brightness of the room in which you are going to use it.

You won’t be able to get a clear image with a low output projector that is used in a room with high lighting. Also, you should get a projector with high brightness if you are planning to use it outdoors.

Contrast

The contrast of the image represents the difference between the black and the white shades. Usually, a contrast ratio of 10,000:1 is enough for you to get a clear and sharp image. If you get a projector with a lower contrast ratio, you might notice that the picture is a little washed out sometimes.

Throw Distance

The throw distance represents the distance between the projector and the screen. The rule when deciding the throw distance your new projector is going to have is to think about the place you are going to use it.

If you are going to use your projector in a small room, then you should get a short-throw projector that you can place in a confined room at a distance that doesn’t exceed 30 feet. Not only will this ensure that you end up with a larger image, but you will also get fewer shadows and less eye glare from both the projector and the screen.

Lamp Life

It is crucial to consider the lamp life of the projector you will buy because this adds to your expenses. Most of the cheap 4K projectors will have a lamp life that is lower than 10,000 hours. This is not good enough to be honest because they will need to be replaced more frequently.

On the other side, some cheap models like the LG HU80KA use an innovative technology that extends the lamp life and makes it more durable.

Screen Size

There is no rule when it comes to the size of the screen you should get. At the end of the day, it is a matter of personal preference. You will find a range of screen sizes on the market. Most of the 4K projector will have a screen size that can go up to 150 inches, but some models allow you to get a bigger screen that can reach 300 inches.

Fan Noise

The noise of the fan affects your overall experience. Some projectors are so quiet or make a minimal sound. Others are just too loud and will distract you while watching your favorite movie or playing a game with the guys.

Frequently Asked Questions:

What Is HDR?

HDR stands for High Dynamic Range. It is a technology that allows your video image to be built from a wider gamut of color and brightness.  This enables you to get better details for your pictures and videos.

Are Cheap 4K projectors Suitable for Gaming?

To decide whether a projector unit is suitable for gaming or not, you need to look at two factors. The first and most important factor is the lag time. For you to have a good gaming experience using the projector, it should have no lag time whatsoever. The other factor to consider is being compatible with gaming consoles.

Which Is Better, Lamp, or Laser Projectors?

To cut things short, laser projectors are better because they are more durable. However, if you don’t use the projector for prolonged hours and only watch a movie or two on your weekend, then you can settle for a lamp projector and save some money.

Final Verdict

It can be a little hard to decide which projector to buy. And now that you have gone through our list of the cheapest 4K projectors let us sum things up for you and help you set your eyes on which projector to get.

Optoma UHD60 has the best image quality of all the projectors on our list, whereas the Optoma UHD51A is more flexible and easier to use thanks to the built-in Amazon Alexa Voice Control.

Both Epson Home Cinema 4000 and LG HU80KA are excellent choices for gamers due to the absence of lag time.

Epson Home Cinema 5040UB is the quietest projector on our list. It has got a bit of everything and will do a decent job when it comes to both movies and gaming. However, you should note that it has a lag time of 48ms, although it is compatible with gaming consoles.
