I've just tested the G900 on my laptop and Audio Visualizer works with it there just fine. Switched it to my desktop along with G900 receiver and it doesn't worked anymore, so it must be something wrong with my PC, but what could it be?
The desktop runs latest Windows 10 Professional and laptop is a bit outdated and runs Professional 1803. Both are 64 bit versions of course.
The desktop is an AMD plattform on ASUS X470 STRIX with Ryzen 7 1700X & GTX 970 and laptop is an old MSI GS60 2PE FullHD running Intel Core i7 4700HQ & GTX 870M.
I don't have any ASUS Aura or Halo software installed on my desktop. To be honest, I don't have any ASUS software installed as for now. I need almost all of the installed programs on my PC but need to get rid of the one or more which may conflict or at least report them to Logitech. May you check if there's one you know about which could conflict with Logitech G Hub on my PC? It's easier for me to check it as at least 2/3 of them are installed on my laptop as well. I've sorted out all different applications, with exception that these on my laptop may be a bit outdated as I haven't started it for last 8 months.
Installed applications which aren't installed on my laptop:
AIDA 64
AMD Chipset & AMD Software (both coming from chipset driver downloaded from ASUS motherboard support page)
Argus Monitor (insetad of ASUS AiSuite III garbage, for controlling fans and making curves only)
ASMedia USB Host Controller (coming from drivers downloaded from ASUS motherboard support page)
Defraggler
EasyNotes for Keep (UWP app)
Folder Marker
Forza Hub (UWP app)
GTA III, GTA VC, GTA SA, GTA IV and GTA V. Last two are Steam games. Rest are from CD/DVD media.
IcoFX
Intel SSD Toolbox
Kaspersky Internet Security (on laptop there's Kaspersky Free version installed)
Malwarebytes Anti-Malware (this one I've bought for 2 weeks ago and the trouble with Audio Visualizer is since 1 month ago)
Mozilla Thunderbird
Pro Evolution Soccer 2019
Rainmeter (haven't configured it yet, just installed)
Realtek Audio Console (UWP app came along with sound drivers downloaded from ASUS motherboard support page)
Realtek High Definition Audio driver is 6.0.8765.1
Sonic Studio III (UWP app came along with sound drivers downloaded from ASUS motherboard support page)
Samsung Magician
VirtualClone Drive
Winaero Tweaker (on PC it's installed, on laptop I run portable version of it. The same tweaks has been applied)
I've a lot more installed on my laptop and PC. These I listed above
AREN'T installed on my laptop, which I think could conflict, if it's not anything else.
EDIT: I need to say that LG Hub on desktop works a bit differently to LG Hub installed on laptop.
Effects on my laptop switches immediately after they has been switched.
Everything just works as it should. Just need to choose any of them and they're applied right off. It's not the case for PC. When switched from OFF to Fixed/Cycle/Breath on it, the RGB remains turned off. I need to first click on "Sync lightning zones" to get RGB on and then configure that effect. When switching from any of effects to OFF, it still lit. Something is really wrong with it on desktop.
If anyone gets on mind to tell me about the format, don't do it. I'll not format anything.
I've just uninstalled Samsung Magician and Intel SSD Toolbox as they both was really not needed on my desktop but it wasn't because any of them. This thing on my desktop works really weird. Though keyboard isn't synced with mouse it shows the same synchronized effect for them both, like a half of functionality is broken or don't work. I'm sooo pissed off of it but won't give up until it's working as intended.
