TopAV buying advice
Is the ViewSonic IFP5551 right for your classroom?
The smallest panel in the series, with none of the specification cut away.
Shortlist this ViewBoard for a small classroom, a training room or a huddle space where people sit close to the screen and write on it. At 55 inches the writing area is within reach of a single standing adult, which suits one-to-one and small-group work. Check the furthest viewing distance carefully, because this is the size that runs out of legibility first.
Reasons to shortlist it
- 50-point touch with palm rejection, so a hand can rest on the glass mid-sentence. Write Away starts annotation when a pen is lifted to the screen, without opening an app first.
- The front USB-C port carries video, touch and 65W of charge to a teacher's laptop, so the desk is one connection rather than three. The rear and top USB-C ports supply 15W each, which is what a webcam needs.
- 70W average audio output from two 25W front speakers and a 20W subwoofer, with a built-in 8-array microphone, so a small room needs no separate soundbar or conferencing mic.
- 16GB of memory and 128GB of storage on an octa-core processor, the same platform as the larger panels in the series rather than a cut-down one.
- EDLA certification means Google Play, managed accounts and MDM policies behave the way your IT team already expects, rather than apps being side-loaded.
Check before you choose
- 55 inches is legible only at short viewing distances. For a full-size classroom or any room deeper than a few rows, compare a larger panel before deciding.
- Budget separately for the mount, installation, and any slot-in PC or camera your workflow needs. None of those is included with the display.
- EDLA is not a substitute for an IT compatibility check. Confirm account policies, app licences and the supplied configuration.
See the 55" on your wall, to scale
On a phone, point your camera at the wall and see the 55" there at its real size. On a computer, upload a photo of the wall (or scan the QR code to take one with your phone and it will appear here) and drag the display around it to scale.
Not sure 55" is the right size for the room? The screen size calculator shows how far a 55" display carries for presentations, touch work and video.
What to plan before installing the IFP5551
01
Size & sightlines
Measure the longest viewing distance and allow space around the display for access and writing.
02
Mount & connections
Check wall construction, mounting height, power and data. ViewSonic lists a 400 x 200 mm VESA pattern.
03
Software & installation
Confirm the supplied software configuration with your IT team. Tell us if you need mounting, cabling or a camera.
Display price is for the panel. Installation and optional equipment are quoted separately. Purchase-order terms are available to approved education customers.
Build a quote you can compare
Include these details in your project enquiry so the quote covers the room as well as the screen.
- Number of displays, site postcode and required date.
- Furthest viewing distance and available wall space.
- Wall type, fixed mount or adjustable trolley, and cable routes.
- Laptop model, teaching apps, and any camera or Windows PC needs.
Ask for separate equipment, delivery, installation and licence costs, with a total including VAT. Confirm warranty coverage and any registration requirements before placing the order.

ViewSonic IFP5551 questions answered
Who is the ViewSonic IFP5551 best suited to?
Consider it for a small classroom, a training room, a SEN or intervention room, or a huddle space where people sit close to the screen and write on it. Measure the furthest seat first; 55 inches is the size most likely to be too small for a full class.
How much RAM and storage does the ViewSonic IFP5551 have?
16GB of memory and 128GB of storage, on an octa-core processor, as listed in ViewSonic's specification table for this model.
Which version of Android does the ViewSonic IFP5551 run?
Android 14, EDLA-certified, so Google Play and managed Google accounts are licensed on the device rather than side-loaded. EDLA panels receive Google-licensed updates in service, so the version installed on a delivered unit can be later than the one it shipped with.
Is the 55-inch model specified lower than the larger ViewBoards?
Not on the core platform. ViewSonic lists the same 4K resolution, 50-point touch, 500 nits, 16GB of memory, 128GB of storage and 70W average audio as the 65-inch IFP6551. The differences are physical: screen size, the mounting pattern and power draw.
Can I connect a laptop with USB-C?
Yes. The front USB-C port supports video, touch data and up to 65W power delivery. Your laptop and cable must support the required functions; a laptop needing more than 65W will still want its own charger. The rear and top ports supply 15W each.
How bright is the IFP5551, and is that enough for a sunny room?
ViewSonic lists 500 nits for this model. That suits a normally lit room. In a room with large unshaded windows, plan blinds or check the panel against the actual light levels before committing.
Does it include a Windows PC or a video-call camera?
Treat these as separate requirements. ViewSonic lists slot-in PCs and cameras as optional accessories for this series. Ask for a quote that identifies the PC, camera and mounting hardware you need, rather than assuming they are included with the display.
Should I choose a 55-inch or a 65-inch ViewBoard IFP51?
Choose by viewing distance and the smallest text people need to read, not by room capacity alone. Both panels are 4K, so a larger screen makes text bigger rather than sharper. Compare this 55-inch panel with the 65-inch IFP6551 using the screen-size calculator and a check of the available wall space.
Can TopAV quote for installation and school purchase orders?
Yes. Request a project quote for mounting, cabling and installation. Installation is quoted separately. Approved education customers can apply for purchase-order terms; eligibility and credit terms are subject to approval.
Is the advertised price a complete installed classroom package?
No. The displayed price is for the display. Request an itemised quote for mounting, installation, any optional PC or camera and any additional software licences. Compare the total including VAT, delivery and all required equipment.
How does the ViewSonic IFP5551 compare with a SMART Board or Clevertouch?
SMART builds its teaching workflow around SMART Notebook and Ink and Clevertouch around LYNX Whiteboard, while ViewSonic builds around myViewBoard, which on this model runs on EDLA-certified Android 14 with 50-point touch and a front USB-C port carrying up to 65W of charge. Our comparison guides use the IFP51 series as ViewSonic's reference but quote the 65-inch IFP6551-3C, so check the size and the exact order code against this 55-inch model. Our SMART Board vs ViewSonic and three-brand school comparison guides cover software, accounts and installed cost in detail.
