I am hopping someone with an XPS 9570 can help me.
My brand new XPS 9570 arrived in a pretty poorly state. Initial issues were:
So now having spent a good 30+ hours trying to fix the thing here's where I am:
Since doing all of the above I have one remaining issue from the original list a couple of new ones!
Aren't movies at 24fps, so the HDR for movies should output correctly?
For the HDMI out, on my personal setup, I have an HDMI wire running from the laptop to the receiver directly. Then by right clicking on the sound icon in the taskbar, I selected 7.1 output and since then it has stuck to that. From browsers, it will only be stereo I suppose, but you can try downloading a test 7.1 audio file and try playing that.
I use Potplayer, but make sure to set audio settings as "same as input" in Potplayer (default is stereo 2.0)
24FPS and the refresh rate aren't a direct one-to-one mapping, HDR specs require 4k@60hz. 24FPS content is effectively "upsampled" to 60hz (not quite the right technical description). With your setup what HDR panel are you using, most "notify" that they are now displaying HDR (e.g. LG show an "HDR" notification in top right corner) does yours?
I dont even have the option to turn on 5.1 or 7.1... it is greyed-out... whether I connect HDMI to the receiver or the LG panel (both of which work with any other device).
I'm really bored of it now TBH and reluctant to get the device swapped out only to have the same problems hence my interest as to whether anyone else has been able to get Atmos working and/or what experience you've had with HDR output over HDMI.
Oh and to add to my list of woes... now the WiFi is playing up too... keeps disconnecting for no reason (I'm 2 foot from one of my APs)... again from what I read the "Killer WiFi" is not all that great and Dell have swapped some people over to Intel cards when asked to.
I don't have an HDR compatible tv. Are you able to right click on the desktop, go into intel graphics manager settings, then under display select your tv while the HDMI is plugged in and change the refresh rate to 23p or 24p? Maybe that will let the HDR content play correctly?
Another thing I've read before is that the HDMI port uses some settings from the Nvidia card, so perhaps you could try to uninstall and then reinstall the Nvidia drivers from dell support and then the audio settings will show up... Especially if you can select 7.1 audio with your other laptops, it means that the receiver is fine.
I swapped out the killer wireless card for an intel 9260, it was ~$25, money well spent.
This is a good article on HDMI standards, HDMI 2.0a is required for HDR. You can "kinda" make it work with HDMI 2 but it generally requires reducing the refresh rate to 30hz which then "washes out" the colour rendition anyway. So, gut feel is that it HDR isn't really supported.
I've also read some about replacing the NVidia audio driver with the standard MS one but haven't tried that yet. Being that the LG panel is connected to the "Intel Display Audio" driver I'd be surprised if it was the NVidia driver at fault... however as I cant find any clear explanation of how HDMI audio output is handled on the XPS 9570 with it's dual GPU setup I'm at the mercy of Dell support to tell me how to sort this.
As for the WiFi card the drop outs are getting worse and worse...
My whole point with this laptop is it's brand new... none of these issues should be occurring and no one at Dell seems to be able to tell me if a replacement will have the same problems or not. I'm not interested in going through the hassle of a replacement only for the same problems to be present.
Ok, so I have this driver installed called Intel Display Audio which is version 10.26.0.1 under sound, video and game controllers in device manager. Check that.
Also you probably have a netflix app on your tv, I think you should just use that then.
