Question / Help Black screen. Special conditions. Not beating a dead horse.

[etazero]

I have read the many issues that plague OBS and windows update, however, my situation is different.
I am on a desktop and the only thing that changed for me was my video card back on 2-17-20.
I updated from a gtx 1060 to a rtx 2060 super. After that OBS went blank.
I have windows update 1909.
I have OBS version 24.0.3 (64-bit).
I do not have the option to switch to internal graphics via the nVidia control panel. I only have 1 video card.
I have the latest drivers from nVidia (442.19).
Under Window's display settings my "power saving" gpu and "performance" gpu is the same thing, rtx 2060 super (screenshot below).
My old card, gtx 1060 worked with windows update 1909, the last time I used it successfully was 2-9-2020.
I reverted back to Windows update 1903 right before this post, to see if that worked, it did not.
I don't know how this will help, but abiding by the rules, I have attached the log files from today.
At a loss and looking for some sort of insight.

I have almost this exact configuration and upgrade path. My Windows 10 on a GTX 1060 worked just fine. When I upgraded to a GTX 2070 black, all I get is a black screen. Any help or suggestions? Thanks.

call me a ... but
You use a TV as Display with an HDMI cable?
the is a Nice feature for protect content from ripping
"High-bandwidth Digital Content Protection (HDCP)"
check if you have this enabled and if yes disable it
most displays are HDCP ready but its only active if you run a bluray or something similar require HDCP

so there is a 50/50 chance that your TV tells the GPU to enable HDCP to secure the connection
must not be the problem but a grabale reason

Thanks! I'll check on that.

As for an update, I started a recording this morning on another PC and its working fine.
That PC has an old GTX 750ti, windows update 1909, but an old version of OBS. Sorry, I'm not in front of it right now to give you the version. However, it does solely connect to the monitors using DVI, while you're right about the PC in question, it uses HDMI.
So I'll check that when I get home.

Another update.

I checked to see if HDCP was enabled and the only thing I could find that it was "capable".
With that said, I decided to hook up another monitor this time using DisplayPort.
This worked. OBS captured that monitor without fail.
This to me is only a ducktape solution for now and should not be marked as resolved from the powers that be.
I'm still wishing to solve the initial issue at some point.

you got the first goal
we have now the "error" its the HDCP that got activation from the TV
if you are lucky there have a software switch in the TV
look if the TV have a HDCP free HDMI Input or look in the software from the TV if there support a "PC Mode HDCP free"

the issue comes from currently the TV think "every input is a Blu Ray or similar" so ask for HDCP if response must be a bluray player
every PS4 recorder knows the issue with HDCP in PS4 you can only record or look movies with switching HDCP on/off by hand
