3LCD vs DLP Projectors, Which one is better?

DLP Pros:

• DLP projectors provide bright, vivid, crisp pictures with a high contrast ratio and strong contrast.
• Because of the utilization of mirrors, light loss is considerably decreased, and light output is high.
• DLP creates a smoother image comparable to 35 mm or 70 mm film.
• Because DLP projectors have a filter-free and sealed chip architecture, they are simple to maintain.
• Because there is less gap between the pixels, the final image is sharper
• In comparison to other projectors, DLP technology provides a deeper black tone.
• DLP is extremely accurate and produces no shadows.

DLP Cons:

• The DLP technology isn’t as bright as LCD technology for the same wattage.
• Because of the mirrored chip, the DLP has a restricted amount of pixels.
• It may create a rainbow effect because it flashes colors over the screen in short bursts.
• The color wheel can fail over time as it is a fast-moving part.

3LCD Pros:

• The color saturation of LCD projectors is excellent.
• LCD projectors deliver a clearer, more precisely focused image.
• LCD projectors have a higher brightness capability and generate a brighter image for the same power level.
• When it comes to brightness, an important projector characteristic, LCD projectors rank better.
• The LCD projector is more efficient.
• 3LCD projectors will produce brilliant colors and sharply defined pictures even in a bright setting.
• There’s no rainbow effect with 3LCD projectors, unlike DLP.

3LCD Cons:

• ‘Dead’ pixels are common in LCD projectors. A constantly off dead pixel may not make a significant difference, but the projector will be hampered if there are too many dead pixels.
• It’s difficult to move them room-to-room because of their weight due to the many internal components.
• LCD projectors give a densely pixelated image.
• Color homogeneity is not as good as DLP.
• The LCD can degrade quickly, and replacement parts are costly.
• Over time, the image fades as it is not a closed system, allowing dust and dirt to damage the internal components when combined with the excess heat that they produce.

Input Lag (3LCD vs DLP)

Particularly when playing video games, but even just for projecting movies, lag time is very important. The length of the delay might var, but DLP projectors have a higher lag than LCD projectors in general.

Having a higher refresh rate helps, so keep an eye out for a high refresh rate measured in Hertz, particularly a frequency of 120hz. If you have to choose between a 120hz LCD and a 120hz DLP, you should choose the LCD.

There is because with a 3LCD projector, there is minimal lag time due to the colors being formed straight from the crystals rather than a chip passing through mirrors.

However, if you’re choosing between a 120hz DLP and a 60hz LCD, the DLP is the better choice because it has substantially higher speed and will cover indirect color processing.

Resolution and Image Quality

As long as you are choosing a projector with a resolution of at least 1080p and a brightness of 3000 ANSI Lumens, then there are no notable variations in quality between DLP and LCD projectors. If you are interested in 3LCD vs DLP 4K projectors, then DLP become the preferred standard as they are much more widely produced for a 4K resolution. Take a look at my article on the best 4K projectors for more on this.

Convergence (3LCD vs DLP)

When colors join together to produce the pictures you see on screen, this is called convergence. Colors are reflected by mirrors in DLP projectors using one chip or three chips in more high end projectors.

Crystal Panels are used in LCD projectors to concentrate colors. When there’s a convergence issue, the visuals you see will be hazy and full of inaccuracies, as if you’re looking through a dirty window.

Single-chip DLPs win since there’s nothing to converge because they utilize one chip. So there’s no risk of a convergence issue.

LCD and 3-chip DLPs may experience convergence difficulties over time because if one chip or panel is slightly out of sink, it may impact the entire picture.

But by far the most important difference between one chip DLP and 3LCD projectors is the presence of rainbow effect in the former technology.

This is caused by the spinning color wheel, which can produce a rainbow halo around on-screen objects, particularly when they move quickly, or if you move your head too fast while watching the screen.

This is because the color wheel makes the DLP projector overlay each red, green and blue layer of the image, thousands of times per second, usually too fast for the eye to notice, but this does depend on the individual.

This can be a strong negative for DLP projectors, so it’s sensible to try one out in-store before committing to a purchase.
