What is a 4K projector?
4K projectors are projectors that can display images in 4K resolution.
4K is a high definition resolution that is either 3,840 x 2,160 pixels or 4,096 x 2,160 pixels. It is also defined as four times the pixel resolution or twice the line resolution of 1080p. This resolution is usually used in commercial cinema. 4K is also known as Ultra HD or UHD, as well as 4K x 2K, 4K UHD, Quad HD and 2160p.
4K resolution is now found in a variety of uses. One of these is in 4K projectors for home theater setups. There is a growing need for 4K resolution as screen sizes become larger. Lower resolutions such as 720p and 1080p have visible pixels when seen on a large screen. 4K resolution reduces pixel visibility and makes images look smooth and have depth.
4K projectors and Faux-K projectors
There are 4K projectors that use pixel-shifting technology. Pixel shifting technology that improves the resolution of an initial image. This involves an image sensor shifting half a pixel then saving the image. It creates a lot of saved images that are then stitched together for better image quality.
There has been a debate on considering 4K projectors with pixel shift as real 4K projectors. “Faux-k projectors” is a term used by some to refer to 4K projectors with pixel shift. This is as if to suggest that these are inferior to other 4K projectors.
But, “faux-k projectors” are still projectors that can display images in 4K resolution. They are not inferior to other 4K projectors and there are times that those with pixel shifts are better. In the end, it depends on the brand and the device if it is a good 4K projector or not.
How does a 4K projector work?
To understand how 4K projectors work, we must first talk about pixels.
Pixels are elements that contain information for colors red, blue and green. Combining many pixels creates an image. The number of pixels used for an image determines the resolution. For 4K resolution, it needs over 8 million pixels. These 8 million pixels will consist of 3,480 rows of horizontal pixels and 2,160 columns of vertical pixels.
For 4K TVs, 8 million pixels are easy to cram as its screen sizes are large. But, for 4K projectors, they need to cram 8 million pixels into a chip that can go as small as one square inch.
There are two ways that 4K projectors do this.
Native 4K approach
The native 4K approach involves cramming in more than 8 million pixels into a single chip.
Sony uses the native 4K approach in their 4K projectors. For their projectors, Sony places three chips containing 8 million pixels. There are three chips for the colors red, blue and green.
Pixel shift approach
The pixel shift approach involves a 1080p chip of over 2 million pixels copies a 4K resolution chip.
For a 1080p chip to achieve 4K resolution, the projector shifts the chip. The chip shifts until it reached the needed number of pixels for 4K projection. This creates two 1080p images which the projector shows as one near 4K resolution image.
The direction of the pixel shift depends on the brand. For LCD projectors from Epson and JVC, the pixel shift is diagonal. In Texas Instruments’ chip for DLP projectors, it is clockwise. A 4.15-million pixel Texas Instrument chip for DLP projectors shifts in a diagonal way.
Why is a 4K Projector Expensive?
4K projectors are expensive despite 4K TVs going for as low as $300. High-end 4K projectors go for as much as $5,000 while entry-level ones go for around $1,000. So, what’s the reason behind these prices?
The answer lies in the pixels. Fitting more than 8 million pixels into a small chip is meticulous work. So, it also means that it involves some pretty expensive processes to produce a single chip.
Native 4K projectors are the most expensive among 4K projectors. One such brand that has native 4K projectors is Sony and their projectors go for as much as $5,000.
Meanwhile, 4K projectors with pixel shift are less expensive. This is because you only need less work to produce 1080p chips. 4K projectors with pixel shift go for around $1,000 to $2,000.

How to Use a 4K Projector?
The proper use of a 4K projector relies on its proper setup. Your 4K projector may have the best specifications and features. But, without the proper setup, it will all go to waste.
Where to place a 4k projector?
The first step to a proper 4K projector setup is knowing where to place it. You need to know the throw ratio of your projector. This is the ratio between the distance of the projector from the screen and the displayed image size.
For this, you can check your projector’s manual to know the throw ratio. You can also get a hint on the throw ratio by checking if a projector is a long-throw or short-throw. Long-throw means that you need to place the projector far from the screen. Short throw means that you can place the projector near the screen.
You also need to decide on whether to use a projector screen or a blank wall. A blank wall is fine to use for 4K projectors. But, a projector screen allows for a much clearer, sharper and more colorful image on the screen. If possible, find a screen with a black frame as this improves contrast.
Position of a 4k projector
Second, position your 4K projector properly. Your projector should be in a position where the displayed image is not distorted. An ideal place to place your projector is flat surfaces. When in slanted surfaces, some 4K projectors have the option to adjust the screen corners. Also, projectors have a zoom option that adjusts through dials or electronic control.
4K projector’s focus
Third, you need to set your 4K projector’s focus. This will make sure that the image appears clear and sharp. Make sure that there is much less pixelation as you adjust the projector.
4K projector’s settings
Fourth, you need to set your projector’s settings to make the displayed image look perfect. You will need to adjust the settings for contrast, color, brightness, and quality. You can have it set to presets or adjust starting from them.
Fifth, you will need to set up the projector’s audio. Some projectors would need to have an attached sound system. But, some projectors already comes with a good sound system.
What to consider when buying a 4K projector?
Before buying a 4K projector, you need to consider the following. This will help you choose a projector that is worth it and meets your needs.
Purpose Of 4K Projectors
First, know for what purpose you are getting the projector. Know if you are going to use the projector for entertainment or business. Then, know if you will be using it indoors or outdoors. Knowing these will help you know the ideal technical specs for your projector.
Second, check for the 4K projector’s technical specs. Find a projector that is suitable for your needs. Check the projector’s specs for brightness, contrast, zoom range, and lens shift. Also, check if the 4K projector uses native 4K or pixel shift. You can also check if it has other features such as HDMI port, USB port, and Ethernet port.
Third, you need to check a 4K projector’s other features. Check if it is reliable based on how long a projector’s lamp will run. Also, check if its lamp will have a long run when the projector is on maximum settings.
Consider also if the projector is portable. The point of getting a projector is to screen videos almost anywhere. Check if the projector is easy to move from one place and to set it up in another place.
Also, check if you would need other equipment when using the projector. Find out if you would be needing a projector screen or if you would be using a blank wall when screening. Check also if you are going to use the projector’s built-in speakers or if you would be needing a sound system.
4K projector cost
Fourth, check if it is going to be worth it. Remember that 4K projectors are expensive. Make sure that its features and specs are going to be worth the money.
