So, you’re thinking about getting a projector and want to know where the projector needs to be to fill the screen or to get a certain size image. Or you know exactly where you want to install the projector but don’t know how big the image will be at that distance. No problem!
Introducing the Installation Triangle…
If you have any two dimensions on the installation triangle – you can calculate the other one.
So – taking our UHD40 4K projector as an example. This has a throw ratio (TR) of 1.2~1.59:1
If we want a 100cm wide screen – we multiple the screen width by the TR = projection distance of 121cm~159cm
If we know where we want to place the projector (ie 121cm back) and want to calculate how large the image would be – we divide the distance by the TR which gives a screen width of between 76.1~100cm (depending on how much you zoom in the image).
If you don’t know exactly what model you need but know your screen size and where the projector needs to be – you can calculate your TR. This will help you to narrow down which models would fit your room.
But put that calculator away!
Optoma has a brilliant distance calculator on its website that does all the hard work for you! Simply put in one dimension and the calculator will do the rest.
Where you place the projector is an important part of choosing the right projector
Short throw and ultra-short throw projectors can be positioned very close to the wall and still provide a big image on the screen. The benefits here are no shadows and they tend to be brighter by being closer to the screen or wall.
Normal or standard throw projectors sit further back and tend to mounted on the ceiling and above/behind where you would be seated.
If are thinking of placing your projector on a shelf near to the ceiling – don’t. You would need to tilt the projector which would distort the image shape. Install the projector under the shelf rather than above - ideally with a universal mount.
Optoma announced this week the integration of Amazing Colour technology into its latest projectors. The combination of advanced colour technology and multiple settings in all Optoma projectors, from entry level to high resolution, creates precise, true-to-life colours which do not fade.
Outstanding colour precision
Optoma projectors deliver accurate sRGB/ Rec. 709 colours for true-to-life visuals. This provides precise detailed images with more realistic and natural looking colours. Perfect for business presentations, education, films and photography - where detail really matters.
Tailored visual experience
Equipped with multiple display modes, Optoma projectors give users the freedom to choose the best setting for the content. Each mode has been fine-tuned by Optoma’s colour expert team to ensure superior colour performance.
Optoma projectors deliver high ANSI contrast. This means the projector is far superior at differentiating between dark and light content within the same image - providing crisp, intense and saturated colours.
Optoma guarantees colour will never fade on its projectors so users can enjoy consistent colour performance for years to come.
Multi-colour processing technology
DLP® BrilliantColor™ technology raises the bar in colour performance and picture quality. This multi-colour processing technology provides a wider colour gamut, making it possible to produce over one billion colours. It supports the continuous processing of RGB (red, green, blue) colours along with yellow, cyan, and magenta. This gives realistic colour reproduction, particularly evident in skin tones.
Amazing Colour technology offers better colour performance to match any application or environment – whether for business, education or home entertainment. For more information on Optoma Amazing Colour technology, visit: www.optoma.co.uk/Amazing_Colours and watch the Amazing Colours video
With the sun shining and summer around the corner, Property and Facility Managers at universities and schools are gearing up for their busy annual maintenance period. Part of this involves installing new classroom equipment.
Increasing pressure on budgets makes it more important than ever to take all factors into consideration when replacing existing projectors or installing new projectors.
Our blog looks at the key things to consider when choosing a new projector for schools:
Cost: Schools and other education venues are often under pressure to choose the cheapest equipment but this is not necessarily the best deal. Property Managers need to look at the overall cost of ownership which includes the projector, ongoing maintenance, energy saving features and lamp life. It is a false economy to choose a cheap projector that needs regular costly lamps and maintenance.
Maintenance: What maintenance will be needed? Does the projector have filters that need regular cleaning? DLP® (Digital Light Processing) based projectors have a dust-sealed, filter-free design that prevents dust and dirt from affecting the system. This means the projectors need no maintenance as there are no filters to remove and clean.
Replacing projectors: If you need to use existing fittings, check the new projector’s throw ratio. A projector's throw ratio is defined as the distance that a projector is placed from the screen divided by the width of the image it will project. For existing fittings, you just need to check the throw ratio of the new projector enables you to install this at the right distance and screen size. A zoom increases the flexibility in installation. Optoma offers a wide choice of projectors that will fit into your existing fittings.
The room: When choosing a new projector you’ll need to consider the room size and ambient light levels. Optoma has a handy guide on its website to help schools identify the brightness they would need for a small or large classroom, lecture theatre or auditorium.
Warranty and support: What is the warranty on the projector and lamp? If the projector goes wrong – what support will the supplier give to schools? Check if the warranty is ‘return to base’ or ‘DE-RE’. Optoma offers a DE-RE warranty on many of its education projectors. The DE-RE warranty means the projector will be replaced and re-installed in the unlikely event it is found to be faulty, giving real peace of mind to schools that they will not be without their vital equipment. In addition, Optoma’s dedicated UK-based helpline will provide customer support to answer questions and queries on projectors.
Performance: Will the image quality be consistent? DLP® technology uses millions of mirrors which produce higher quality images and does not suffer colour degradation over time, as sometimes experienced in other projector technologies. Optoma is so confident that the image colour quality of its projectors will remain as good as the day you bought it, that it offers a five year guarantee.
Other features: Check which additional features you need. Many projectors can be managed and monitored remotely through network control. This will alert you when lamps need to be changed and automatically powers down projectors at the end of each day to save energy and lamp life.
Do you need interactive capabilities in your projector which enable students to participate and learn together by making any projection surface an interactive one. Consider whether you would like built-in speakers, 3D or wireless capabilities, which allow teachers to present wirelessly from a PC or mobile device.
Security: What anti-theft features does the projector have? Optoma projectors have a Kensington Lock Port that enables schools to attach a lock for added security. Some projectors can also be password protected for added security.
Optoma manufactures projectors with a wide range of resolutions, brightness and throw ratio including standard throw, short throw and ultra short throw and some with a interactivity features. Short throw and ultra short throw projectors can project a 100” image from as little as 0.4 metres from the screen. This is ideal for small rooms where there are space constraints or classrooms /training venues where the presenter is at the front and wants to avoid creating shadows.
It offers a complete solution to its projectors with wall mounts and a full range of accessories. Its Visualisers enable teaching staff and students to share work with the whole class. The microscope adaptors allow tiny objects to be seen by the whole audience. It is also possible to capture and save images from what the Visualiser captures either as photographs or as a video.
