4K (or not to 4K) • Applications • Issues • Image sizes • 4K readiness • Demonstration Reflex.co.uk creating connected workspaces

4K applications • Desktop • Signage • Medical • Simulation • Cinema/telly Reflex.co.uk creating connected workspaces

4K issues • Bandwidth = cost • Image size Reflex.co.uk creating connected workspaces

Image sizes Reflex.co.uk creating connected workspaces

Minimum viewing distance Reflex.co.uk creating connected workspaces

Desktop • 80cm viewing distance • Infocomm 1:6 – 10” • Full HD – 20” • UHD – 41” Reflex.co.uk creating connected workspaces

Small meeting room • 3.3m maximum viewing distance • Infocomm 1:6 – 44” • Full HD – 56-84” • UHD – 84” to 168” (1m – 2m tall) Reflex.co.uk creating connected workspaces

Large meeting room • 8m viewing distance • Infocomm 1:6 – 107” (1.3m tall) • Full HD – 136”-204” (1.6m to 2.5m tall) • UHD – 204” to 408” (2.5m to 5m tall) Reflex.co.uk creating connected workspaces

Auditorium • 16m viewing distance • Infocomm 1:6 – 214” (2.7m tall) • Full HD – 272”-408” (3.4m to 5m tall) • UHD – 408” to 815” (5m to 10m tall) Reflex.co.uk creating connected workspaces

4K summary Reflex.co.uk creating connected workspaces

Scaling Reflex.co.uk creating connected workspaces

Laptops Reflex.co.uk creating connected workspaces

Videowalls Reflex.co.uk creating connected workspaces

Scaling demo Reflex.co.uk creating connected workspaces

Scaling summary • Consistency for users • Clean image switching Reflex.co.uk creating connected workspaces

Audio • Acoustics • Fancy speakers • Surround sound Reflex.co.uk creating connected workspaces

Acoustics - reverberation Reflex.co.uk creating connected workspaces

Pragmatic approach? Reflex.co.uk creating connected workspaces

Audio - NXT Speakers Reflex.co.uk creating connected workspaces

Audio – line arrays Reflex.co.uk creating connected workspaces

Audio – ceiling speakers Reflex.co.uk creating connected workspaces

Audio – surround sound Reflex.co.uk creating connected workspaces

Example – Lecture Theatre Reflex.co.uk creating connected workspaces

Example – Lecture Theatre Reflex.co.uk creating connected workspaces

Audio summary • Intelligibility comes from the room • The right speakers can help • Does PowerPoint even support surround sound? Reflex.co.uk creating connected workspaces

Standards Reflex.co.uk creating connected workspaces

Swiss Army knife design Reflex.co.uk creating connected workspaces

Swiss Army knife design Reflex.co.uk creating connected workspaces

Example – Divisible rooms Reflex.co.uk creating connected workspaces

Example – Divisible rooms Usage Cost per use Cost to hire Worth it? Once a week £100 £500 Yes Once a month £416 £500 Maybe Four times a year £1250 £500 Probably not Once a year £5000 £500 Do you have to ask? Reflex.co.uk creating connected workspaces

Summary • 4K has applications; do you? • Audio quality has more to do with the space than the system • Scaling is your friend • Standards save money • Buy what you need most often Reflex.co.uk creating connected workspaces
