LCD vs DLP Projectors for Home Theater Systems: A Thorough Evaluation

LCD vs DLP Projectors for Home Theater Systems
Spread the love

Investing in a home theater system that’s right for you can be a rather daunting task due to the number of technological developments occurring over recent years. However, we see a rise in the use of projectors, and when deciding to make the leap from conventional TV systems to projectors, throughout your research, you’ll find the common LCD vs DLP projectors for home theater system debate.

To help decide which technology is best for you, we’ve provided a comparative guide that will walk you through the ups and downs of each system.

An Overview of LCD and DLP Projectors

LCD (liquid crystal display) and DLP (digital light processing) are the most widely available projector technologies on the market. Both offer the same benefits seen from all projector systems including the following:

  • Increased screen size: Most projectors can cater to varying size requirements, typically between 50 inches and 106 inches. This makes them extremely versatile as they can fit almost any home environment.
  • Cost-per-inch: Conventional TV’s will see a drastic increase in price with greater sizes. This isn’t the case for projectors as the price differences between projectors commonly ignore screen size and focus on the quality of the image and the functionality of the unit.

Understanding Functionality

Although they have similarities, each technology operates differently and understanding how they work would help you make an informed decision of which is best for you.

Generally, LCD projectors produce light from a lamp through three individual screens that then combine in a single prism before the image is thrown. They work in a similar but more effective way than their CRT predecessors.

On the other hand, DLP projectors use a completely different process altogether as rather than passing light through a screen to the lens, they use a series of microscopic mirrors that are angled to project light from the lamp and then through a color wheel. Most projectors contain millions of these mirrors providing an incredible resolution.

LCD vs DLP Projectors for Home Theater Systems

Direct Comparison

LCD Projectors

  • Rainbow Effect: No
  • Color Accuracy: Light is projected through three individual colored mirrors.
  • Contrast: Cannot produce completely black images.

DLP Projectors

  • Rainbow Effect: Yes
  • Color Accuracy: Color wheel can result in reduced saturation
  • Contrast: The individually angled mirrors allow for deeper contrasts.

A Detailed Breakdown

To provide a thorough comparison on which projector technology is best for your home, we’ll compare each across the three following sections:

  • Image Quality
  • Initial Cost
  • Motion Resolution

1. Image Quality

One of the defining factors in your projector purchase will be the quality of the image displayed on your wall or screen.

  • LCD

LCD units come in single-chip or three-chip formats, the single being less expensive. The three-chip LCD projectors (3LCD) not only provide a sharp image but do so with greater saturation and brightness due streaming light through three individual red, green and blue chips.

  • DLP

DLP’s colors might not be as bright as LCD projectors, but they do offer a great contrast of colors throughout the image resulting in deeper tones. This is achieved through the complete absence of light across pixels when the mirrors are tilted not to reflect light to the color wheel.

Best Image Quality: 3LCD

3LCD projectors offer a better quality image overall due to greater color accuracy and sharper image. This is only found at the higher levels of LCD projectors.

2. Initial Cost

When looking to purchase your projector, the upfront cost is a big determining factor in what system you’ll end up with.

  • LCD

Single-chip LCD’s are significantly cheaper than 3LCD projectors for obvious reasons, but both are considered to be the most affordable options when it comes to projector technology. Even with the lower price, LCD projectors still perform well against their DLP counterparts.

  • DLP

DLP’s can be found at every price point but, as mentioned, are generally more expensive than LCD projectors. This is due to their more complex projection systems that are displayed through its overall higher performance.

Lowest Initial Cost: LCD projectors

For those who may be more budget conscious or looking for some mid-tier projectors, LCD projectors will definitely cost you less both at the beginning and over time.

3. Motion Resolution

Motion resolution refers to the movement blur encountered when a screen can’t display the image at a high enough frame rate. A better motion resolution will deliver a smooth-running video.

  • LCD

Entry-level LCD projectors are more likely to suffer from this blur effect than more expensive models or DLP projectors. This can really ruin any home theater experience.

  • DLP

Motion resolution is considerably better with DLP projectors due to its mirror technology. At all levels, you’ll notice significantly less motion blur and an all-around smoother running image.

Highest Motion Resolution: DLP projectors

When it comes to your viewing pleasure, image distortion can be a real dampener. DLP projectors will help to rid you of this issue and display images just as you’d expect.

Final Recount

Before we visit the pros and cons of each projector system let’s have a quick recap of the final tally:

  • Best Image Quality: LCD Projectors
  • Lowest Initial Cost: LCD Projectors
  • Highest Motion Resolution: DLP Projectors

Pros and Cons

Despite LCD projectors being ahead in our LC vs DLP projectors for home theater system comparison, we’d rate the overall benefits of each system as a tie. Many other factors can influence the quality of a projector and in the end, your home theater experience. We’ll see some of these in our pros and cons section below.

LCD Projectors


  • Sharp image rendering
  • Low cost
  • Bright images


  • Contrast can’t produce completely black images
  • Bulky compared to DLP projectors

DLP Projectors


  • High contrast ratio
  • Reduced pixel
  • High resolution


  • Rainbow effect (a flash of rainbow colors around brighter images)
  • Relatively expensive

Our Verdict

When choosing the best projector for you, there is a range of factors that could have more relevance and greater influence over your final decision. That means that the LCD vs DLP projectors for home theater systems debate might just really come down to personal preference as well as budget constraints.

This being said, we’ve still found that 3LCD offers the most excellent image quality and operation for their price. DLP projectors do have many benefits and typically outperform LCD projectors at the higher price levels with significantly higher resolution, contrast, and portability. However, for the most part, 3LCD projectors will be best for the majority of users.
