One of my schools has 13 of these installed as part of their new build. They plumped for the more expensive option of 72" screens with built in PC's. Each PC has a Blu-Ray drive built in too. OVERKILL for a Primary School!! I was not part of the decision but ho hum!
Anyways back on track - In my opinion, these machines are nothing to shout about. Sure technologically they are good but in terms of longevity they suck. They have been installed just under a year, already we have had one screen that has been replaced entirely and then had the touch surface replaced, Another one has been taken away on express repair (2 weeks ago) for a faulty backlight.
I'm not that impressed with them to be honest. I certainly don't expect equipment like this to fail so often and as such it has put me off them.
One other major gripe I have with them is the way they have been designed. There are 2 Infra-Red emitters in the top corners of the screen. In between these emitters are the cameras which monitor the infra red. Around the bezel of the screen is a reflective strip which bounces the Infra-red all over the display surface. The issue here is that dirt builds up on the screen causing the infra-red beams to be broken thus causing the camera to pick up the break and interpret it as a touch. VERY POOR design if you ask me.
I wouldn't really recommend these as an option in a primary school.
Let me check this Monday / Tuesday as I'm positive I remember testing the new model LCD's in W7 and starting with my finger in the middle of the screen and the mouse pointer being with me and as I ran my finger up the screen the mouse pointer got further and further away.
Will test it start of the week and come back to you
It may be worth noting also regarding sound through HDMI that I had to make a bios change to allow the machines we have to play sound out the HDMI. I can't remember exactly where it was off the top of my head but if it doesn't work for you worth checking your bios
Thanks for your comments, I am intrigued by the screen-res comment, I have always take it to be a linear X Y grid with no variability centre to border. If you have a recomended screen res to try that works best for you, please share it so I can see if it makes a difference. I have tried a 25 point calibration and not found it to improve reliability.
The weight will vary from size to size, we now have 7 of them within our school and a 55" screen is 59kg. We also have 3 of them in the primary we support, 2 wall mounted and one on a movable trolley with the 'up and down' feature for the little children.
With the newer models of the CleverLCD (we have 3 of the old models and 5 of the new models) the speakers are inbuilt and they have HDMI connection so you can run sound through this and you dont need a 3.5mm jack, on the old models they had DVI but no HDMI and the speakers were a seperate purchase and were screwed into the bottom. You can tell the difference as the new ones have beveled corners, the old model was a lot more square.
With the new models you dont have to install a driver, they are plug and play in Windows 7. From memory they also dont need calibrating.
The main issue with the 55" screen we have found is when using programmes like Excel in class rooms which you would consider more than average in size. The cells are just too small to see from the backs and corners of rooms. With this in mind you need a bigger screen which means more weight and more money, just something to consider (whilst pinch to zoom works on the CleverLCD's in Office 2010 it isnt ideal and is restrictive teaching wise).
Another issue which has been raised with us regarding the CleverLCD's is a lack of a freeze frame option like projectors have. I've spoken to the CleverLCD manager at Sahara and this isn't something they will be implementing until the end of 2013, so he said.
We purchased our screens and had them installed by @Millgate in Sheffield and have been happy with them but I don't personally think they are an automatic replacement for projectors and interactive boards just yet.
Oh, one more consideration, will the teacher truely make use of the interactiveness the screen provides or are they going to use it like a big TV? If the answer to that is 'probably not' then why not just buy a big TV? It's something we've considered for going forward, main issue being if the teacher moves on / out of the room and a more proactive teacher comes in..........problem!
Lynx has some nice features but is far from the complete package, the integration with google earth etc is nice though.
EDIT: just watched your video on calibrating, if you go to settings and change calibration to 25 points it will be more accurate, this may help with some of the issues you have had
EDIT: just watched your 'fine control' video for resizing the text box, I believe that your screen res will affect your accuracy towards the top and bottom of the screen in Windows 7, if it isnt right the accuracy will be fine in the middle and way off to the top and bottom, as seems to be the case on your video.
Yes around £3K April, although the prices are falling so they should be cheaper now. Weigh that up against a full projector and smart board install, which has some in built obsolescence with the traditional projector lasting around 3-5years and then requiring a bulb a replacement. In my experience the schools haven't budgeted for bulb replacementwhich leaves the teacher struggling on with the classroom either in virtual darkness or pupil's squinting to see a faint projected image coming from something with the output of a gloworms armpit! With LED/Laser projectors coming onto the market it will be interesting to see whether these provide the longevity that they promise at a price schools can afford.
The real question is whether this direct contact interactivity is worth the extra cost? The primary function is to display information to a group, this can be achieved at a fraction of he cost with a standard TV with an HDMI/vga input retailing for around the £4-500 mark for something decent with excellent viewing angles and probably less reflection, and lower running costs (LED screen) A wireless mouse or wireless slate could provide the pupil interactivity (and keep Ofsted happy!) all for under a grand.
finally. the website files from the old host have been emailed through to me in a zip file. total size 5.2 MB
How does the cost compare?
It's all well and good saying these screens are better, but if they're too expensive I doubt a lot of places could afford them.
I know we probably couldn't. [I saw one priced at nearly £3000. I don't know if this is cheap or expensive.]
Given the choice between upgrading desktops and installing a gimmick, I think I'd upgrade the desktops...
can i ask which settings you changed. and ill try if from this end first. thanks shame i cant thank you in a blog
Try what they've given you with "ftp." in front of it
i supposedly have the server address but i get a 530 error each time i try it 530=Authentication. i have no faith in this company what so ever.
It's funny you mentioned cats, as in the printers' district of pre-revolutionary Paris, a series of ritualistic murders of cats took place, which were apparently caused by printers' apprentices who were fed up of the way they were being treated by their masters.
I'm not saying murdering cats is a viable alternative to striking, I'm just saying it happened.

I have already tried this with this software package but it misses out the images and some of the pages from our site so i dont know exactly where the stuff is stored or how the crawler works as it is all in the same web directory. i suspect some of them are linked in by a CSS sheet some where to be honest.
also they are supposed to be supplying me with ftp access but as of yet they have only given me a username and password and when i asked what the server address was he gave me the name of his web hosting company. is it me or has some one lost the plot.
If it's just a plain old site you can just run a webcrawler to download all the css/html files then reupload on new host.. HTTrack Website Copier - Free Software Offline Browser (GNU GPL) is what I had used when I had to do it at my old school.
Suggest making a forum post rather than a blog post... Windows Server 2000/2003
I'm waiting in anticipation for the virtualisation bits to start!
Guess it depends on how critical back up is to your business. Worth looking at your business model or infrastructure. There may be other areas where you can streamline and save costs to which you can get a better back up system.
Great when you've got the money Our budget is next to nothing; at least, it's no difference when we need to get rid of every single OS on site, replace a great chunk of computers and buy in servers & licensing, than it was last year or the year before when just ticking over. The saving of circa £2k per server was more than enough. Besides, going with intel-everything except the RAID cards thanks to availability gives us the same sort of reliability and warranties.
Some cracking progress though this week despite it being very broken up (day and a half out supporting primaries) with nailing DFS replication, solving a small issue with AD replication not being instant - didn't realise the minimum time for replication between AD sites is 15 minutes, but a small tweak put that back to same-site default of up to 5 seconds. AD structure is *finished*, all security groups *finished*. Base GPOs *finished*. Base Windows 7 image with Chrome and Office 2010 *finished* Some "nice" customisations like school logo for logon pictures done. Libraries cracked and pointing to the right places, many thanks to this cracking post : http://www.edugeek.net/forums/window...ding-wiki.html
Attempted to sort out the KMS host for Office 2010 licensing but it's got some stupid thing where you can't actually even test it with less than 5 clients trying to activate. Back end is done at least.
Had to remove and reapply the distribution point on Server 2 due to it using the C: drive as a secondary package/source location so I could force it to the specified drive but no big deal.
Next week - importing a large batch of users (Year 13's are a great batch to play with as the majority have left now!) to test with. Just need to script shares/DFS structure.
Ouch. That's why I just buy servers off the shelf from Dell. Certified to work with zero problems just pop the ESXi CD in and 10 mins later your done.
Also Veeam Backup free edition is great for quickly making ad hoc backups or even ad hoc migrating VMs between servers. I am loving it for £0!!!
Hi, have you got the code to create am html signature for each user?
