I stopped using roccat quite a while back due to the constant disconnection issues then the servers going down. I've heard people recommending Gameglass which do have a very small cost, but give much better immersion and usability than Roccat ever could.
See their 'shards' or screens, here.
Personally, I massively went OTT after I stopped using Roccat....
Here are the screens from a couple of years ago (after Roccat), which is not much different now, although slightly improved and an extra tablet not shown in the first two overview pics, but shown below those:
The other angle:
Then the next 3 from August 2020. Main 10" tablet in front of the chair. Which has Elite Companion, plus the left buttons down by myself in Rainmeter:
Voiceattack tablet attached to the left of my chair, with Rainmeter volume + Mic slider and visualiser built by me:
View of the tablet above and the new tablet I mentioned. The new tablet at the top, shows everything in text which EDDI is saying so I never miss anything:
Lastly, the phone at the end of the throttle. This was done in rainmeter again but this is the old version. Now, there's an animated gif of my anaconda flying in the background, rather than a static image. Basically, with 7/1 sound, I see a visual representation of where sounds are coming from, which I can easily see the direction on here too
Edit. If you want to use tablets and phones as PC monitors like I do, there's a free app called spacdesk which you can find on the play store and google search. Most of mine are connected that way, except the Elite Companion centre piece. That's connected with TwoMonSE which costs only around 7 quid and allows you to connect to the PC with usb cable - so it's always 100% smooth with its maps etc
