Projectors or TV?
We have an ageing fleet of Sahara and other projectors that will need replacing over the next couple of years or so and I'm wondering about the best route to go down.
We have fitted a number of ultra-short throw Hitachi projectors which give an excellent image and are reasonably priced. However some of the rooms can't take these because of the height between the top of the Smartboard and the ceiling. With that in mind was wondering if anyone had any thoughts about large touch screen TV as a viable alternative to a ceiling mounted LED projector.
The rooms I have in mind aren't that large but obviously my main concern is that it can be viewed easily by students at the back of the class. Cost would also be a consideration of course!

I've seen commerical/industrial screens 65" for around £3,000 with 60,000 hours useful life this compares favourably with even casio led prpjectors there no security cage nor speakers to add to the cost of an IWB they are more expensive initially but the lack of bulb changes the ease of install and the fact that they can last betwen three and six times the lengh the casios can do would mean they are a good option when looking at TCO. The size compares nicely with IWBs of 75"-77" as the contrast ratio is higher and they are usually clearer images i may look into them myself when our older NECs die instead of a casio projector. Also of course site licensing software from rm etc is significantly cheaper than for smart tech.

That seemed to be about the going price at BETT this year from various companies.

I have to agree, I've always thought Interactive Whiteboards are over-rated. Using a touch screen device such as Win 8, Android or iOS, you can clone your screen onto a larger screen from a distance, perform interactivity from a distance (without blocking the screen), but also hand over control to a pupil without them leaving their seat.
You could get away with a projector displaying on a white wall as no board or TV is required.

I have been toying with the idea of interactive TV's myself and had someone come out to give a demo of CTouch 55" interactive TV last month. Have to say I was quite impressed as the brightness and clarity more than makes up for the smaller screen when you put them next to each other. For a smallish classroom I found the 55" would be big enough but for a largish room in my opinion you would want a 65". Having no pens to lose, potentially no remotes really needed and no bulbs, and only a HDMI and USB cable to attach is very tempting. The 55" was about £2,500 installed with a five year warranty which I though was pretty reasonable compared to a whiteboard install but the 65" was over £3,000 I think which was a bit pricey for me at the moment.

We are just about to move into a new school, we have gone for 65" CTouch after months of testing etc, the clarity and longevity not to mention the power savings, no calibration etc make 3000 for one of these a no brainier these days.
The only issue is the software, if like in our school the IWBs are just PowerPoint presenters you have no issues, but Prometheus and smart require you have their board if you are going to use their software.

Have to agree with the comments above we have just installed 2 65" CTouchs and the response from staff and students has been positive, but we are only putting them in depts/classroom that can justify using the touch features.
I know our D+T dept is being refreshed over the summer and he would just prefer TV screens and it makes our lives easier not having to install projectors etc, i think as we replace IWB/projectors over the coming years it will either be with a TV screen or a touch screen.

We've just bought a bunch of 60" touchscreens for about £3k each. It should save a bunch of cash on projector maintenance and replacement over their lifetime
Welcome to software lock-in. Promethean are pretty terrible for this. We are trying to wean our staff away from it because of the aforementioned problem, their restrictive licensing for working at home and the fact that their format is useless for VLE's.

We are mainly a Promethean school at the moment but for the very reasons above I am slowly weaning the staff off this software by not replacing or adding any more Promethean boards. I ended up buying a site licence for RM Easiteach for a very reasonable price (compared to the main competitors) which to be honest I didn't think was too bad (and still don't) which can be installed anywhere in the school and will slowly become the teachers only option for interactive software.

Some interesting comments - thank you.
I'd love to replace the projectors and Smartboards with large touch screen TVs but the cost is prohibitive where there are already working IWBs even though the projectors need replacing. The issue of the interactive software is also interesting too as I really don't know how many teachers actively use it.

I know your using hitachi ultra short throws already. But I'm using Epson 475wi and they mount to the wall above the board. The bracket can mount flush with the top of the board (you'll need 30CM of space above the board) So unless your board is flush with a very low celing then it should have room. The top of the image will drop 25CM below the bracket (if you have a massive 84" 16:10 image) The drop is less with a smaller picture and if you adjust the bracket you could raise the image further.
Most of our whiteboards have about 18 inches above them but when mounting our interactive projectors we found that many short members of staff couldn't easily reach the top of the image, so we had to lower it anyway. This lead us to just install the projector almost flush with the board. (the epson is only £1000 and is itself interactive)

The interactive displays are the best option when having this issue of board to ceiling measurementís. I have had the same issue recently problem which a local primary so theywent with our 65" interactive displays which under £3000 fitted. They comewith a 3year onsite re-install de-install warranty which is always a plus withthis kind of solution.
If you require any further infomation on audio visual solutions please contact me.

Ours came with 5yr onsite warranty. I don't think 3yr is enough for a £3k outlay.

Sounds great, Good Work.
Yes we can offer a 5 year warranty on most of our Education AV Products.

How heavy are some of these screens? We have been asked to investigate alternatives to IWBs but we have a lot of stud walls & think that they probably wouldn't hold the a decent sized screen.
& someone mentioned no additional speakers needed. Are the built in speakers really enough to fill a room with sound?
