XPS 8960, black screen
XPS 8960
Hi,
I recently bought the new dell XPS desktop (8960), and since purchasing I've had an issue with a black screen. The PC starts up with the dell logo, and then after the logo it stops sending signals to the monitor.
I've had support work on me with this, it was first perceived to be a problem with the OS. An engineer came to install a fresh windows 11. When we got into the desktop, and started manually updating the drivers..it happened again.
Then it was hypothesized as a graphics card problem with how it responds to the latest drivers, so they were planning on replacing the motherboard for my PC. I ended up having the whole PC replaced. Got my new PC yesterday and the exact same problem.
I'm waiting for a response from support, but meanwhile I was wondering if anyone has had this happen, what the problem was, and how they fixed it?

Sounds like my problem form last year with the 8950 and internal graphics, tried multiple cables, this is the one that worked for Display port to HDMI monitor

My XPS8960 is scheduled to be delivered tomorrow. Configured with i7-13700K and AMD Radeon RX 6700 XT. Please tell me how yours is configured. Just hoping that your problem is not widespread with the 8960.

@Otim95 - If you have an add-in video card (AMD or NVidia), is your monitor is connected to the add-in card, not to the onboard Intel Graphics DisplayPort, correct...?
What port are you using on the add-in card and what port on the monitor? Any video port adapters being used?

No add-in video card, just Intel UHD Graphics.
Im using a the displayport in the PC and displayport to HDMI cable to connect PC to my monitor

Since the problem is common to both 8960s that you tried, I'm wondering if it could be an issue with the display port to HDMI conversion in the cable. If you can get (borrow?) a monitor with a DP input, it might be worthwhile to try it with a DP to DP cable.

@Otim95 - Have to agree with @modelman, which is why I asked about your video connections.
The onboard Intel Graphics DP port on the XPS 8960 is Dual-Mode DisplayPort 1.4. (Marked:
on back panel of XPS 9060.)
That means you don't want/need an active DP(PC)>HDMI(monitor) adapter. You need a passive DP(PC)>HDMI(monitor) adapter, which only changes the type of connector, without changing the video signal.
Also keep in mind video adapters typically only work in one direction. So you can't just turn them end/end and expect them to work.
Or, if your monitor has a DisplayPort input, just use a DP(PC)>DP(monitor) cable...

Thanks for clarifying what might be going on with my adapter. How do I know if its an active DP->HDMI or passive DP->HDMI?
My monitor only has HDMI input and USB-C (DP Alt mode) input. (From my comments to Joe and modelman) I've bought a couple of adapters to see if they work, they should be arriving tomorrow. One of them I'm trying is Displayport -> USB-C, and the other is another DP->HDMI with the hopes that it is indeed passive DP>HDMI (Joe confirmed it solved the problem for him).

Bought this just now to test if it works, thanks. I'll try it tomorrow (as well as trying Displayport to USB-C)

Yeah I guess you're right, the only thing left is to focus on how it's connecting to the monitor.
I don't really have another DP input monitor I can borrow (and can't afford to buy one for the experiment lol), but I'm willing to try a different adaptor. My monitor has HDMI and also USB-C (DP Alt mode) input, so I've just bought a Displayport to USB-C to see if that works, ill test tomorrow.

@Otim95 - Passive DP++>HDMI adapters are offered at various sites listed here. I'm sure there are others too.
All passive adapters do is change the physical connectors. There are no electronics inside to convert a DP signal into an HDMI signal. With dual mode DP++ on the PC, it automatically detects when it's connected to an HDMI monitor and sends out an HDMI signal.
If you already have an HDMI cable for this monitor, you don't need to get a more expensive passive adapter with a long cable built in. Just make sure the adapter with short cable is male on the DP end to plug into the PC and female on the HDMI end to be plugged into by your existing HDMI cable.

@Otim95 I am not sure how to know if an adapter is active or passive unless the manufacturer states what is it. Usually, active adapters cost more than passive adapters but I don't think that is a guarantee. In your situation, I think you should be able to use a passive adapter since your DisplayPort source is dual-mode DisplayPort. (The specs for the XPS 8960 state Dual-Mode Displort 1.4. and there should be a "DP++" symbol next to the port.) See this article about passive and active adapters: https://blog.tripplite.com/whats-the-difference-between-passive-and-active-displayport-adapters

This cable worked, thanks @Joe Shades
Perhaps this was a passive adaptor, I'm not sure @RoHe @Vic384 @modelman

@Otim95 Glad that worked. So now enjoy your new toy..!
FWIW, Dell actually offers an adapter that should work with DP++(PC)>HDMI(monitor) in your setup.
