What is 4D Keystone Correction?
4D simply means “4 Directions Adjustable”
When you set up a Projector at home, it may not display a perfect rectangular shape. Also, when you try to adjust it, the picture gets blurred. On the other hand, when you see the Projectors at any events or movie theatres, they fit any surface and display crystal-clear images.
The secret behind this cutting-edge technology is nothing but a feature called 4D Keystone Correction.
Keystone Correction is a feature in Projectors that helps you adjust the image with crystal-clear projection. We have explained in detail about Keystone Correction in our previous article. Now, what is 2D & 4D in Keystone Correction?
How is 4D better than 2D Keystone Correction?
You can see the 2D Keystone Correction Projector in the below image.
It has a mechanical wheel using which you can Adjust the Lens of the Projector until you see a Rectangular Image. The 2D Keystone Correction allows you to adjust the image in 2 Directions only. Hence, there is a high possibility that you still can’t see a perfect rectangular image. Moreover, disturbing the lens might make it lose focus and project a blurred image.
Therefore, Projector manufacturers have come up with 4D Keystone Correction. In 4D Keystone Projector, you can adjust the Lens in 4 Directions. Hence, increasing the possibility of portraying a perfect rectangular image with crystal clear image quality.
This technology employs advanced algorithms and optical adjustments to correct image distortions caused by projector misalignment. It fixes distortions in both axes as well as adjusts the tilt or angle of the lens.
Most Digital and Auto Keystone Projectors have the 4D Keystone Correction feature. Hence, if you are planning to purchase a new Projector, it is wise to look for a Projector with such feature.
Also, it is very easy to access the feature. You might find the option in Projector Settings or on its Remote Control. You just need to put the Projector in its place and select the Keystone Correction, Lens Shift or Screen Fit option. It would be easier for the Projector to detect and correct the image if you have Black Borders on your wall or Projector Screen.
In the below video, you can see how smoothly and quickly the Keystone Correction is Done.
Hence most Projector Manufacturing Companies like BenQ, Epson, etc. are making Projectors with this feature.
Benefits of 4D Keystone Correction:
Here are the Benefits of Purchasing a 4D Keystone Projector:
- Elimination of Distortion: Eliminated Distortion and provides clear images regardless of projector angle or placement.
- Enhanced Viewing Experience: Offers an enhanced viewing experience while projecting presentations, movies, and other media.
- Versatility: You don’t have to worry about placing your Projector on rough surfaces or projecting on uneven walls
