Does display size really matter? It sure does!

Does Screen size really matter - DIB Audio Visual

Ah, the age-old question in AV; does display size really matter? In our 20 years of experience in supplying AV solutions to the education and corporate sectors, display size does matter. This is particularly true in the education sector, specifically within the classroom setting.

The main reason for understanding the importance of Display size is because if you want students to clearly read text on the main display, FONT size is important.

As a summary, display size more importantly has to do with height of an image (LCD or projected), which directly correlates to the height of fonts. This is of particular importance in an education setting, where students can be sitting as far away as 6m from the display. As you lower the size of a display (height), this can produce readability issues, which could present a huge problem in the learning process.

This potential issue is increased by the current types of content being used on the main display, which are often created on desktop/laptop devices. No longer is it just Powerpoint presentations, but collaborative learning such as using content from websites or Google documents.

To help understand, we’ll take a 100 inch, 4:3 ratio display as a reference point, which was the standard display for many AV systems in classroom approx 10 years ago. These AV systems gave a display height of 1.5m.

Many schools of recent times have been considering NEW LED TVs as their main display in classrooms (with a 16:9 ratio). Many of these are under 70 inch, typically 60 inch in size. With this size LED TV, the height of the display is 0.74m. This is less than HALF the height of the 100 inch display!

Another way to explain screen size importance is by looking at differences in FONT sizes. If you displayed the same text at 10 font and 20 font on the same screen, representing the 60 inch TV and the 100 inch displays. Then gradually walk backwards. It wouldn’t be too long before you can’t read the size 10 font.

It’s this dedication to educating clients on these types of aspects of an AV installation that make DIB Audio Visual a class leader in the AV industry.
