Lets keep the LCD stuff in a thread of its own 
He guys, thanks to @RBM weāve got our own space 
Ok. Back to the screen part. Iāve got stuff scrolling. Looks great I must say.
But now the bad part. Doing scrolling stuff on the screen requires hardware acceleration (for the non-geeks: basically a way that drawing to the screen is being taken care of in hardware in stead of the software) and that part is extremely buggy and in progress on the Raspberry Pi.
I canāt get it to work reliably, so for now Iām afraid this is a no-go. Which is extremely frustrating, because the scrolling looks so good and it took me a while to get it actually working 
Anyways, letās stop with the whining. Iāll follow progress on this area closely, and itās already in the software, but itās just disabled. It also means that we really need the āmultiple screensā option, because right now some of you (including me actually) are not that happy with the little space for texts etc.
Thatās it for now, keep you guys posted.

Great plan Harry.
Ok my PI just timed rebooted and the display is all unknown and blank art. Granted thee is no playlist on roon controller at this time. So I sent feedback.
I did notice that your last screenshot had radio turned off.
If you actually pause a song before you go to bed, have a look tomorrow whatās on the screen after the scheduled daily reboot. I wonāt be surprised if the last song you paused still shows on the touchscreen in the morning.
When you have this āunknownā showing in the morning, if you start playing something in the morning in Roon, does Touchscreen come alive again? Or only a manual ārebootā or cold boot brings it alive?
All is still not wellā¦I went into roon and hit back in the top area to last nights playing albumā¦hit playā¦though thatās louder than I rememberā¦it was still set at 24ā¦I thought this might be a bad sign so went to the volume adjustment and soon as I touched it it jumped to max vol on the digiamp+ and I swiftly mini used it to 0 where it when quiet, but moving it up again even to 5 resulted in max vol on the speakers.
@spockfish
I sent a feedback both in the unknown state and again in the 0 volume state and will now shutdown and power up again
Some more fun and gamesā¦My 2 extra LCDās arrivedā¦and casesā¦ very nice case from RS Onlineā¦post a pic later
BUT now with 2 cores and 2 LCDās its impossible to tell which is whichā¦so not sure if the Ropieee Hostname can be identified in the extension detailsā¦that would be a huge help
This is the RS Online case http://sg.rs-online.com/web/p/development-board-enclosures/9064665/ also comes in White and Clear ā¦I got a black and a clearā¦but hard to get a HAT in there - can mount on a wall tho - handy here is a UK link bundle http://uk.rs-online.com/web/p/graphics-display-development-kits/1228914/?origin=PSF_431023|alt
Thatās a nice bundle for Ā£60. The Pi is increasingly a RAAT-enabled Squeezebox Touch on steroids.

Boot time with a display for those that are worried its taking some time is round 10 mins to get the web page to respond. and then you can do things like set the time zone, boot time, HAT, USB, zone monitoring name and screen orientation if its upside down 
@spockfish Harry now I have 3 LCD screens running ā¦ the defining of the HostName in the extension is really desirable.
Another thing is that using 2 Zone Monitoring of the same name is working fine
BUT I think there bis a problem changing all the settings in one goā¦I think the time I got it to work was when I didnāt change the orientationā¦and on that note I think that 99% off all screen installs will be upside-down so a default for rotated might be a better default.
I also noted there an AutoBoot option that is set to 1 - so this a setting for the future to be able to force ones own updates?
And on that noteā¦is it possible at all to have the web page reload back to the non commit or shutdown link as I often just hit refresh and wonder why the system is restarting againā¦ just for the unwary user
Using the same setup: RPI 3, 7" official 7" TouchScreen, Case.
Iāve got some huge audio interferences on USB output using DietPi / RoonBridge with touchscreen linked.
See: https://community.roonlabs.com/t/powering-raspberry-pi-3-touchscreen
Iām powering RPI+screen from the same PSU at the screen level (microsusb connector from Ifipower 5V 2.5A). Seems possibly to be an under voltage issue ?
Iām interested in feedback from other users about SQ with and without screen.
Currently my choice is to use RPI + Touchscreen out of the audio path as a display/control device only.
Is the same Extension name for multiple zones an issue?
I setup multizone Ropieeeās for my old man and once you hit enable for both extensions, you should never have to look at that screen ever again.
So in my old manās system, giving it different names wonāt change anything because itās a āonce offā step.
Itās not like giving each Ropieee a host name where you do need that to identify things daily.
Itās very stable now (apart from your āunknownā title issue which I hope gets sorted of course).
I may be missing something though where it may be useful giving each extension a different name but canāt think of any case? Itās a āset it and forget itā thing with the extensions (I think)
Having said that, for ācompletenessā it might be good to have each extensionās name link to the ropieee host name, as you requested already. Just to make it look cleaner
One thing I forgot to ask you last time - why not plug your microUSB cable into the Pi, not the Screen?
So the screen will be powered by the Pi, whereas currently the Pi is powered by the screen?
Does it make a difference?
Thank you Sean.
Currently iāve unlinked the screen from my PI to be able to enjoy music but will try:
- Powering PI and screen from two distinct 5V PSU (via microUSB)
- Powering at the PI level (microUSB too) from only 1 PSU according to your idea. For this test do you think the 2 GPIO links (red and black) are OK to feed the screen.
Yes it wonāt work without those links - thatās actually what those links are for - sending power both ways.
If using 2 separate 5V PSUās, disconnect the red and black links.
@volpone also if you are using a 3B you donāt need the other connections that come with the screenā¦ this is all you need
https://www.raspberrypi.org/learning/addons-guide/display/
Thank you @wizardofoz.
Iām using 3B and this is exactly how are my connections.
Unfortunately quite a lot of interferences on USB output when powered from screen microUSB via 5V, 2.5A PSU.
Under DietPi iāve got yellow thunder bolt symbol on desktop display. I think this is āunder voltageā indicator.
donāt shutdown, just reboot.
Well yes if I want to reboot thats what I doā¦but sometimes i need to shutdownā¦like if I need to swap power supplies or move the unit so then when I plug it back inā¦brain has forgotten and just does a refresh page and poof shutdown again
