Microsoft display adapters aren't bad - but only work with Miracast so no iOS devices and require firmware upgrades at the device, so they can't be managed centrally. But at the price point they're hard to beat!

Whole screen has shrunk to half the size, or cropped half the image? Tried an auto image on the projector?

On Win10 - right click speaker in tray, choose "Open Sound Settings". From here click "Manage sound devices" (under Troubleshoot). Here he should be able to see the projector via HDMI - click it and select "Disable". Should stop it from happening ever again!

We're using the Sony FW range for non touch. Very quick start up time from standby, UHD resolution and great brightness. About £100 cheaper than our standard touch display. Worth a look IMO.

Maybe consider a USB boundary mic instead of a headset. Samson UB1 is our go to for these kind of things. As an aside - do you need cameras? Would desktop capture and audio be enough? Would do wonders for your bandwidth.

I personally have to question to logic behind this request - the teacher is not in school but the pupils are? Surely if the pupils are in school the teacher should be as well? Who's managing discipline etc in the room? How about one to one assistance for those who need the extra help? A teacher perhaps? Also consider GDPR and Safeguarding - ESPECIALLY with Zoom. I imagine extra parental permissions would have to be in place, and clear signs to show that a session is being streamed (we have to do this when recording for lecture capture, a light on the lectern illuminates to show recording is taking place). I can imagine a lot of parents wouldn't be happy if anyone could zoombomb a session and watch their offspring from anywhere in the world... But - reasoning aside - to do this properly would need at minimum some form of PTZ camera system (a wide angle shot of the class might work, but you would get blind spots which, I'm sure, would soon be found and exploited by pupils), echo cancellation for microphones and probably a few microphones (ceiling mics could work well). We're starting to look into "feedback" systems for remote learning such as this, more for sessions being conducted between 2 campuses where 1 specialist teaches 2 classes simultaneously, with another lecturer in the other location for local support. Certainly more to it than an iPad and Facetime I think!

Our standard is the Logitech Meetup. Yes it's a little pricey but it does the job very well - and if you've been to any trade shows for the past 3 years there's a reason why they're everywhere! Also started to put Dell USFF PC's behind the screens with a bluetooth keyboard and mouse. Makes for a very nice, slick install.

Only really using the VC aspect of Teams, which we really like. Telephony is handled by Skype4Business (we have the OnPrem version for our landlines) and we have a WhatsApp chat for team use. Add to that Yammer, Slack, OneNote, service desk software and email (and EduGeek!) and I can spend most of my day monitoring comms rather than doing work...

Touchback is possible via Miracast but not Airplay apparently (see https://support.airserver.com/support/solutions/articles/43000533965-can-i-control-my-mirrored-miracast-device-from-airserver-touchback-)

Working in a receiving theatre and smaller festivals mean I've met lots of comedians, actors and public figures, some of the more pertinent ones... Gave James Dyson a bollocking - I was gate guard (checking ID's) at RAF Lyneham and he hired half a hangar from us to keep his jet and helicopter in. He came up to the gate in his Range Rover and opened his window to show his pass, and a disembodied hand appeared from the rear to wave some more ID cards at me. I very curtly explained that his cars privacy glass was working very well and how the hell am I expected to check the photos match if I can't see their faces? Fortunately he was the funny side of it... Became friends with Keith Chegwin - I was working backstage on panto (doing lots of magic door openings and set moving etc) and he would wind us up every night by trying to make us miscue etc. I was only working half the run so on my last performance I opened a door for him into "Wishy Washy's Laundry" (It was Aladdin) as he walked through he grabbed my wrist and tried to pull me on stage screaming "MUM! I've got someone here who doesn't want to pay for their laundry!" Punters had no idea what was going on and the crew were in stitches! He still bought us all Christmas Dinner though, top bloke. Taught James Cracknell (Olympic gold medal winner) how to embed videos in PPT. He was doing one of his motivational talks and was all over the place, so in between sessions I went over and showed him the ever so simple "Play automatically" and "Play full screen" options, it was like I had taught him a new language or something. Amazing how the simplest of things can make people happy!

This is dead easy. Open your backing track in Audacity. In Preferences (Edit>Preferences) under the Recording option click "Record on a new track", then OK. Make sure your mic is selected as the input source, connect your headphones. Hit record - the sax player will hear the backing track, sax is recorded in it's own track in Audacity. Once the song is recorded, mix down the volumes to suit and export. Don't think anyone would complain about this approach being taken, especially for an audition.

A headache

He's new. Not the first thread he's resurrected.

Not sure how well this would work for an interactive session. We use lecture capture extensively recording screen content and audio, but this is only really useful for lectures, not the usual secondary school style teaching where you set exercises, work through problems, check understanding etc. I think the easiest way would be publish any digital resources ahead of the lesson (PPT's, .docs, PDF's etc) and have the students join in on a Skype call. Providing the students have a device they can view the resources, hear the lesson, be asked questions and ask questions back.

Just something else to ask - are you using original lamps or 3rd party?

My italics... Some are cutting in and out, some its the picture. This suggests 2 different problems? 1 where the image jumps and 1 where the image signal is briefly lost? This flickering only seems visible when a laptop/computer connected. So the projector menu screen is not affected - on either of the issues above? Is there an on board test picture you can load to see if the symptoms remain on this? All VGA and cable length 10-15 meters depending on classroom. This should be fine - if it was HDMI at that distance I'd be a little worried. Just changed over a projector in one room that had it worse than the others and the issue is still there. Resolutions all different from laptops but the laptops have been tested on other projectors and all working fine. Cant remember what resolution the projectors are at. Those projectors are WXGA - 1280 x 800. If laptops are outputting higher than that (1080p for example) it may be a simple case of the projector can't cope with the signal it's being given. Your other projectors may have higher resolution capacity hence why it works on them. Try running them at a lower resolution (1366 x 768?) and see if the symptoms remain.

By flicker do you mean the whole image moving, or is the image cutting in and out rapidly within the same projected image? Hope you can understand the difference I'm trying to ascertain! Also some details on configuration could be useful - are you connecting via HDMI or VGA? What resolution are you driving it at? Approx cable lengths?

We're an Epson house - using the laser models and love them! Disappointed with the Casio LED's we've installed in previous years, we've all but replaced them now. My advice - do the maths and get the right lens for your throw distance above everything else (ideally in the middle of the zoom range). Yes there's a lot of options for scaling and quick cornering etc, but ultimately these affect image quality. Taking the time to get it right on paper means an easy install later on. And don't be afraid to move install points if you need to - yes it may cost money but if it's in the wrong place now it'll always be in the wrong place and so the install will always be compromised.

You shouldn't - they're being re-branded as Maxell. (Remember them?) Lampless every time for me. Our standard is now Epson lasers, installed the first one around 3 years ago and hasn't missed a beat once. We had one issue with a fan which was sorted out, that's with around 100 installed so far. Try and get a brighter projector than you need, then look at constant brightness. It reduces the fall-off of the laser brightness, so running a 5k projector at 70% will give a more constant image than a 4k at 100%. OT - long classrooms and touchscreens are a recipe for disaster. You can't mount them high enough so that those at the back can see. (We mount touchscreens 1m off the floor so that everyone can reach the top of the screen). Either turn the classroom through 90 degrees and make it wide and short, or use a projector.

We're using these - active USB A to USB B cables. No breaks in the chain, no conversions to Cat5 or anything silly like that. Installed a lot of these now and no failures. Highly recommended. For HDMI we use these - again no breaks in the chain and no conversion. You do need to get it the right way around though so the amplifier works. Again no issues with these - lots installed. Hope this helps!

This is how we do it, Switcher / Scaler goes in between PC and Projector so other devices can easily be added in such as a visualiser, laptop, blu ray player etc. If you start to go HDMI make sure you get one with EDID management so the devices still think they're connected to a display when they're not being used - saves PC's etc constantly going from single display to dual display which can cause frustration!

Are you connecting via HDMI or VGA? If HDMI I'm wondering if the cable length from PC > Visualiser > Projector is too long, hence only supporting limited bandwidth of 1366 x 768? Perhaps try connecting a monitor on the HDMI out of the visualiser with a shorter HDMI cable and see if you can replicate the problem?

Could make the successors account before you leave and just forward any important stuff over, including previous discussions with SMT about projects so the email chain continues?

Sounds like your dongle's knackered. I use this one - genuine Apple product and not had any issues with it.

Henley Theatre Services (HTS) are pretty good, Stage Electrics are also top notch.
