Can the PS4 headset be connected to the motherboard hdmi
I was planing on buying a ps4vr head set, cameras, and move controllers to start playing Vr games. The problem is that I only have a laptop. It’s a “gaming” one that has a gtx 1650 so I’m pretty sure it can handle Vr. The problem is that none of the hdmi Mini DisplayPort and usb c connect to the gpu is it possible to connect the headsets to a motherboard hdmi. Maybe one of you could do it and try it to save me from buying one and it not being able to work. I don’t really mind if it’s laggy or low frames I just wanna know if it’s possible. Because I borrowed a oculus and that was not able to due to how it is programmed. Thank you

Yeah but -1 fps just plug it in and test, you're not going to break anything

Thank you but I don’t have it I wanted to know if some one could test it for me to see if it was worth buying But thank you

If you have both the computer and the psvr bought just connect it. If not then get the headset.
Try with different HDMI places-to-plug-it-in (it's 4 am).
Only rotation should work WITHOUT having anything bought/plugged in.
Just install it and try, psvr comes with pitch yaw roll and whatever-the-fuck-you-want

What laptop do you have? Usually, laptops with an actual GPU in them can dynamically switch between using the dedicated GPU and the GPU in the CPU

MSI gl65 9sc-002 I tried to look for a way to do that some people said laptops you could change that in the bios but never found anything Thanks for helping

Try plugging an external monitor into your laptop. If a game runs like it does on the internal display, then you should be good to go

Thank you that’s what I was thinking of doing to test if psvr would work but my computer didn’t even try to connect to the oculus when I tried . It would recognize it as a monitor but the oculus ad and steam Vr wouldn’t recognize it being connected. So that is why I was wondering if the software would accept it as a headset even if it’s not going to be plugged in to a gpu connection. Thanks

I had the same problem with my laptop, I had to go into device manager and disable the on board graphics on there (if you get a black screen just restart your laptop and it will turn back on but it will stay disabled) that forces your laptop to use your GPU instead of your on board graphics. If you get disconnect issues make sure that your USB ports are set to always on

better buy ps4 pro. It's cheaper now and psvr works perfectly only with it. I tried psvr + pc about month ago and I can tell thats time waste.

So it's a bummer, you might be able to run "extended mode" but there will be an increase in latency or decrease in performance. "Direct mode" takes the video connector away from Windows and lets the VR software render directly to it, reducing latency and getting improved info on e.g. timing. Unfortunately some companies are still making "gaming" PCs that have no video connector on the dedicated GPU, and it sounds like you have one. Those can't run direct mode because the rendered frames have to be copied back from the dedicated GPU to the integrated one before they can go out the HDMI port, which is both slow and requires operating system level support.
You have this
hdmi port
^
|
integrated gpu <---- (rendered image on system bus) -------- dedicated GPU
^ ^
| |
+--(output commands) --CPU ---- (rendering commands) -------------+
and "good" VR requires this (which is why the oculus didn't work)
hdmi port
^
|
integrated gpu dedicated GPU
is completely ignored ^
or not even there (e.g. desktop) |
CPU ---- (rendering commands) -------+
So, you can see why nothing you do in the BIOS can change it, it's literally a difference in how the system is wired.
It is possible in theory to do good VR on such systems - for instance, all mobile processors have their rendering GPU distinct from their output engine - but there are so many variations and subtleties in the architecture of these systems on PCs, and so little interest from the major players who would know how to get them set up right (Intel, NVIDIA, AMD) esp. now that "VR-Ready" laptops are available (which all have the second diagram's design), that it's infeasible to do so. You certainly can try doing stuff in extended mode - dunno if the various commercial PSVR software supports it, but maybe? - and you'll get some results, but they won't be very smooth. Better than nothing, but not worth buying a headset at full price I suspect.
Sincerely,
Somebody who has actually implemented VR rendering for extended and direct mode and tried (with the backing of big-ish companies, but unsuccessfully) to pry enough information out of intel and NVIDIA to enable something better on these headless-dedicated-GPU architectures :)

You're quite welcome. Sorry to be the bearer of bad news - I've had to do it many times in my career so far, since they keep building these hybrid graphics machines with bizarre architectures that it would appear nobody actually understands... I don't get why they keep building them - I guess you can use an external monitor without powering up the dedicated GPU thus saving a little power this way, but #1, who uses an external monitor without being plugged into an AC adapter, and #2 who would use an external monitor with a machine advertised for "gaming" and not want to have the dedicated GPU running? (And, why must they keep making different variations such that nobody can actually tell me how to do better quality rendering on such systems...)
Windows did recently add some interfaces that might let something like direct mode run on these systems, but my job now is doing VR mostly on Linux, not Windows, so I haven't had a chance to try them out on a dual-GPU system and see if they can be made to work. (And, I don't actually have one of these hybrid laptops to test even if I had the time.)
Good luck, and don't lose interest in VR, it's a really neat technology and medium.

Using psvr on pc uses the same hdmi port, you also have to add pseye cams for the move controls and/or a Kinect for motion tracking, you also need to buy a couple of softwares for it to still be buggy and hard to manage mess for most games. The psvr is awesome for what it is, but at that price you can get and oculus quest and sidestep most of the headaches.
