web@justlikeu.be — Mon, 18 May 2026 07:30:38 +0000

Introduction

When choosing a projector, one question almost always comes up: should you go for LCD or DLP technology?

These two technologies have dominated the market for many years and each offers specific advantages. However, behind these technical terms lie significant differences that can have a major impact on the image quality, durability and usability of your system. Understanding these differences is essential to making an informed choice.

LCD technology: how it works and its features

3LCD technology is based on the use of three separate panels, each dedicated to a primary colour: Red, Green and Blue. Light passes through these panels, and the image is reconstructed by combining these three light streams.

Colour reproduction in LCDs

Thanks to this process, the colours are natural, balanced and true to life.

purple = red + blue
white = red + green + blue

This technology is particularly popular for presentations, detailed visual content and professional environments.

The limitations of LCD

The main drawback of LCD screens lies in their handling of black. Even when the image is supposed to be black, light continues to pass through, and black areas appear dark grey. The result is less pronounced contrast and a loss of depth in dark scenes.

Service life

LCD panels have an average lifespan of 7,000 to 10,000 hours (depending on temperature, ventilation and usage).

DLP technology: how it works and its key features

DLP (Digital Light Processing) works in a completely different way. It uses micromirrors that reflect or block light. As a result, black corresponds to a total absence of light and white to maximum reflection. This produces a very high contrast.

DLP image rendering

Key advantages: deep blacks, high contrast, sharp and dynamic images. Main limitation: colours are generated via an RGB rotating filter, which can sometimes result in less vibrant colours, particularly on single-chip DLP models.

Mono DLP vs 3DLP: a key difference

Mono DLP

Uses a single chip and an RGB rotating filter.

Advantages: affordable price, good durability.
Disadvantages: less accurate colours.

3DLP

Uses 3 LEDs (one per colour) without a rotating filter.

Result: exceptional picture quality, perfect colours, deep blacks, high brightness.
Drawback: very high cost (up to €70,000).

DLP lifespan

DLP systems offer a longer lifespan: up to 20,000 hours. Ideal for heavy use and professional installations.

Quick comparison: LCD vs DLP

Colours: LCD (Very accurate) / DLP (Good to excellent)
Contrast: LCD (Medium) / DLP (Very high)
Black: LCD (Grey) / DLP (Deep black)
Lifespan: LCD (7,000–10,000 hours) / DLP (up to 20,000 hours)
Heavy use: LCD (Average) / DLP (Excellent)

Which one should you choose, depending on your needs?

Standard use (offices, meetings, presentations)

Recommended LCD for its accurate colours, pleasant display and good value for money.

Heavy-duty use (museums, continuous display, digital signage)

DLP recommended for its superior durability and low maintenance.

High-end applications (cinema, simulation, immersive experiences)

3DLP recommended for maximum quality and flawless rendering.

A common mistake

Choosing solely on the basis of price or a technical specification can detract from the experience, cause visual fatigue or limit the impact of your content.

Real-life examples

Corporate meeting room (used 4–8 hours a day, PowerPoint / video conferencing): LCD recommended.
Museum / exhibition (in use 7 days a week, continuous screening): DLP recommended.

Conclusion: LCD or DLP?

There is no single “best” technology that suits everyone. The right choice depends on your intended use, how often you use it, and your budget.

What Light Output Should You Look for in a Projector? A Complete Guide to Making the Right Choice

web@justlikeu.be — Mon, 18 May 2026 07:22:47 +0000

Introduction

When choosing a projector, many users focus on resolution or brand…
But one criterion that is often overlooked is actually crucial: light output.

A projector with insufficient brightness can render an installation unusable:

image too dark
lack of contrast
eye strain

Luminous flux is therefore a key factor in ensuring a comfortable and professional viewing experience.

What is the light output of a projector?

The light output refers to the amount of light that the projector is capable of projecting onto the screen.
It is measured in ANSI lumens, which is the industry standard for projectors.

The higher the number of lumens:

the brighter the image
the longer it remains visible in a well-lit environment

Why is brightness so important?

Unlike a conventional screen, a projector is heavily dependent on its surroundings.

Poor lighting can lead to:

a dull image
dull colours
a loss of clarity

Conversely, good light output allows you to:

to maintain ambient lighting
to improve user comfort
to make meetings more dynamic

How do you calculate the ideal light output?

The brightness depends directly on the size of the screen.

A basic rule used in the audiovisual sector:

≈ 2200 ANSI lumens per square metre of screen

Practical example 1: 2-metre screen

largeur : 2 m
hauteur : 1,125 m
surface : 2,25 m²

Puissance recommandée :
2,25 × 2200 = ± 4950 ANSI lumens

Practical example 2: 1.5-metre screen

- area: 1.28 m²

Recommended output:
1.28 × 2200 = ± 2770 ANSI lumens

Factors to consider

The theoretical calculation serves as a starting point, but several factors influence the final decision:

01. The brightness of the room

dark room → fewer lumens required
bright room → higher power required

02. Usage

PowerPoint presentation → moderate brightness
detailed video or image → higher brightness

03. Screen size

The larger the image, the more the light is “diffused”

04. Visual comfort

The human eye perceives a brighter image as:

more distinct
of higher quality

Common mistakes

Under-rating the power

the most common case

Result:

image that is difficult to read
frustrated users

Over-engineering unnecessarily

unnecessarily expensive

may cause visual discomfort

Case study (business use)

Standard meeting room:

écran 2 à 2,5 m

ambient light

Recommendation:

5000 ANSI lumens

Cela permet :

de garder une ambiance lumineuse

to take notes

to interact comfortably

Home cinema use case

dark room:

sufficient lower power

priority:

contrast

image quality

Light output and perception of quality

A fact that is often overlooked:

A brighter image is perceived as sharper, even if the resolution remains the same.

This means that:

Increasing the brightness can sometimes be more effective than switching to 4K

Conclusion: how do you make the right choice?

Key points:

base: 2200 lumens/m²
adapt to the environment
don’t overlook ambient light
think about actual use before the technical specifications

2K vs. 4K Resolution: Which Should You Choose for Your AV System?

web@justlikeu.be — Mon, 18 May 2026 07:05:45 +0000

Introduction

Als het gaat om audiovisuele installaties – of het nu voor een vergaderzaal, een thuisbioscoop of een professionele ruimte is – is de kwestie van de resolutie onontkoombaar.
Moet je kiezen voor 2K of 4K?

Although 4K is now ubiquitous in marketing hype, the reality is often very different in practice. Given the available content, the technologies used and the actual needs of users, this decision warrants a thorough analysis.

2K vs 4K: the differences explained

The 2K resolution corresponds to a resolution of 1920 x 1080 pixels, also known as Full HD.
This resolution became widely established in the 2000s with the arrival of Blu-ray players, games consoles such as the PS3 and the Xbox, and the first high-resolution screens.

The 4K resolution corresponds to 3840 x 2160 pixels (UHD), which is four times as many pixels as 2K.

In practical terms, this means:

a more detailed image

greater accuracy with large formats

a more immersive experience

But is that difference always visible? Not necessarily.

4K: a promise that needs to be qualified

Contrary to what you might think, the fact is that: the majority of available content is still in 2K

Films, presentations, professional content… Native 4K still has a relatively small market share (around 15% of the market).

Direct consequence: Most 4K devices use a technology known as upscaling.

Upscaling: fake 4K?

Result:

Upscalingmeans that a 2K image is converted to 4Kby artificially increasing the number of pixels.

sometimes really tasty

sometimes mediocre

It depends:

the quality of the projector or monitor

of the algorithm used

the type of content displayed

This is why two 4K devices can produce very different results.

Monitor vs projector: two different approaches

Monitors (screens)

Nowadays, as soon as you go above 32 inches, 4K has become the norm.

Why?

reduced viewing distance

high pixel density

better readability

In that case, there’s hardly any question about it: 4K is the way to go.

Spotlights

When it comes to projectors, the situation is different:

90% of projectors remain at 2K or equivalent

4K models are more expensive

The visual impact depends heavily on the projection size

In a standard image, the difference may be barely noticeable.

What criteria should you use when choosing?

The choice between 2K and 4K should never be based solely on resolution.

The following must be taken into account:

1. The type of content

PowerPoint presentations → 2K is sufficient

High-end video → 4K is worth a look

2. Image size

small → slight

large → 4K is more appropriate

3. Viewing distance

close-up → 4K resolution

distant → reduced difference

4. The budget

2K = best value for money

4K = higher investment

Specific case

A standard meeting room in a company:

75-inch screen

average distance: 2 to 4 metres

The result: 2K is more than enough in 90% of cases

A high-end conference room or showroom:

extra-large screen

premium visual content

The result: 4K is becoming appealing

The most common mistake

Many companies opt for 4K simply to ‘look modern’.

Problème :

unnecessary expense

no real gain

poorly allocated budget

A good installation depends not only on the resolution, but on the system as a whole.

Conclusion: 2K or 4K?

In summary:

2K: sufficient for most purposes

4K: ideal for demanding environments

The right choice always depends on:

actual use

environmental

of the budget
