How to choose the right screen…

How to choose the right screen…

One size definitely does NOT fit all!

With such a confusing range of display options to choose from, choosing the right size and type of screen for specific applications and particular spaces can be time-consuming and difficult…

How to choose the right screen…

And how to know - or prove - you’ve selected the right one?

All too often, displays are barely ‘good-enough’, rather than ‘best in class’ for their application and location - a missed opportunity to impress clients and guarantee best value.

Use our quick-reference screen guide to understand the four size categories and how to identify the best technology for your needs quickly - and with confidence. 

Let’s start with a spoiler alert: if you don’t get the image size right according to the DISCAS standard’s 6:1 rule (or application of its %Element Height exercise) in today’s socially distanced spaces, you fail at the first step.

Farthest viewer
from screen
Minimum screen
height (m)
Screen size
4 0.8 65
5 0.95 75
6 1.1 86
7 1.25 100
8 1.4 110
9 1.5 120
10 1.7 135
11 1.85 150
12 2 160
13 2.25 180
14 2.4 190
15 2.5 200

What size should my screen be?

For a quick and easy way to choose the right display with confidence, we have created this simple 3-Step Guide to Display Success.

Small - up to 55"

Screens up to this size are the go-to option for smaller meeting and teaching spaces up to approx 4m deep. Social distancing has ended shoulder-to-shoulder room layouts, so using the largest size possible lets users spread out while retaining their full engagement.

This size category is a mass market for digital signage throughout built environments.

The products are known as ‘flat panel displays’ (LED-illuminated LCD panels), commodity items available from distributors and resellers. For serious content display use 350cd/m2 (‘nit’) image luminance (or ‘brightness’) and for signage opt for 500cd/m2.

Always ensure the screen has an anti-reflective matt surface - and ALWAYS use professional-grade displays. Using domestic grade screens, displays - or even TVs (Heaven forbid) - you risk reliability and control issues that can end up costing you more than the most expensive display option in the long run. 

Medium - up to 98"

The volume market for meeting and small teaching spaces up to around 7m deep. 

Up to 90”, use flat panel displays. Again, for serious content applications, use 350cd/m2 image luminance (‘brightness’) and  500cd/m2  for signage applications. It’s vital to choose screens with anti-reflective matt surfaces, with your own eyes - and ALWAYS use professional-grade displays.

Above 90” it’s better - and cheaper - to use projection. But it MUST only be projection done properly. This means using ALR (ambient light rejecting) screen technology coupled with laser projectors. Avoid yesterday’s error of using matt white screens which guarantee poor results in high ambient light and waste the money spent on the projector.

Go straight to our Complete Laser Displays: guaranteed to deliver standards-exceeding image quality at a fraction of the price of flat panels.

Large - 100"-120"

Displays for medium/large meeting rooms and small/medium teaching spaces - from approx 7m deep. Projection is the only effective technology here - but only if executed properly.

Our VDL Digital Canvas has unlocked this important category, providing an all in one large screen optical projection system based on AVIXA AV standards for guaranteed image quality at ANY size giving you and your client a complete display that can exceed all relevant global AV standards.

From these sizes, if you plan to locate the bottom of the image around the standard 1.2m from floor level, you can start to bump up against the ceiling! In these cases, set the top of the image up to 10cm from the ceiling and accept the lower ‘baseline’. The top priority is that the image is big enough for the farthest viewers - always.

Extra-Large - 130" to any size

Displays for large spaces. Here, we’re back to two main technologies where choices are high stakes and you risk expensive non-retrievable mistakes.

If you’re presenting serious content, such as teaching, business meetings, presentations, then projection is the only choice - but it must be done properly. 


Direct view LED (dvLED) screens are the go-to choice for digital signage, plus there are outdoor options. They are bright and impactful - too bright for extended ‘serious’ viewing. Also, viewers cannot sit nearly as close to the screen as they can with projection.

Specifying dvLED displays can be a nightmare as apparent like-for-like comparisons hide a vast array of quality issues, based on a ‘binning’ system whereby individual LEDs are graded. Let us help you through this minefield!

It means using a scientifically selected bundle of laser projector, ALR (ambient light rejecting) screen, plus mount. These complete display packages are carefully curated on the basis of delivered image performance, so they can exceed the globally adopted AVIXA quality standards.

Are off-the-peg solutions off-the-table?

When can I use a standard ‘brown box’ flat panel?

Is there a 100% hassle-free way to use Standards to ensure my clients have their needs met, exceeded - and even to enhance our working relationships?

Off-the-peg solutions don't always tick all the Standards boxes or work well in spaces with high ambient light levels, but we can help tailor those screen solutions and technologies to your exact requirements, ensuring that you don't create 'cheap seats' for your audience.

  5. Can I use projection in a brightly lit room?

What is the best projection screen?

  • Choose the right screen for your requirement and budget
  • Type - fixed / portable / electric drop-down
  • Size - from 100” up to any size
  • Brightly lit rooms require specialist ambient-light rejecting screens
  • Small spaces require compact ultra short-throw displays

Our range of professional projection screens from dnp denmark, Euroscreen and Draper includes electric drop-down, manual, fixed frame, frameless and seamless modular screens of up to any size and specialist technologies such as ambient light-rejecting screens for brightly lit conditions. This gives us the best possible selection to ensure we have the right screen for your requirements.

Is a flat panel display better than projector and screen?

  • It depends on size and budget
  • Up to 90” choose a flat panel display (professional grade anti-reflective surface)
  • Over 90” choose projection (for best results ambient light rejecting (ALR) screen + laser projector)
  • Over 90” flat panel displays are much more expensive than ALR laser projection

Our Complete Laser Display is an all in one solution (ALR screen, laser projector and mount) that is guaranteed to deliver AV standards-exceeding image quality at a fraction of the price of flat panels. From 100” to any size.

What is the best display for a meeting room?

Use AVIXA’s DISCAS and PISCR/ISCR global AV standards to calculate minimum size and quality requirements for viewers’ needs. For small – medium rooms, professional flat-panel displays are suitable. Larger rooms require larger displays – for example a 6m deep room requires a minimum screen size of 100” to ensure viewers can clearly see and engage with content from everywhere in the room. At this size, projection is the appropriate solution, but it should be ambient light rejecting (ALR) laser projection for best results.

What are the best displays for a lecture theatre?

Lecture theatre displays must be large and powerful enough for detailed content to be clearly viewable from everywhere in a room. From 100” and above, a projected display offers the best size / cost / quality ratio for large displays for detailed viewing.

Can I use projection in a brightly lit room?

Yes, but to avoid weak, washed out images you need a specialist technology. With a standard projection screen you need to control the light level in a room to get a decent image. An ambient light-rejecting projection screen will deliver crisp, bright, high-contrast images even in brightly lit conditions. When paired with a maintenance-free laser projector you get a better result that a flat panel display at a fraction of the cost.
