@_discord_738643037512663072:t2bot.ioivry.vr I haven't tried it, being not that interested in writing my own compositor. SteamVR definitely doesn't use that. In the table, WMR uses 0x01 and PSVR2 (and other PCVR headsets) uses 0x02. I was not able to get 0x01 headsets working with SteamVR at all, even though that type is able to present an EDID (and have it overridden). 17:32:15
@_discord_738643037512663072:t2bot.ioivry.vr It would be possible (if type 0x01 headsets can be used by DisplayCoreYadaYada) to write a custom SteamVR driver that used "Driver Direct" and DisplayCoreYY. I was looking into a similar approach to combine LiquidVR output and nVidia rendering, but stalled on getting any LiquidVR sample code at all. 17:39:42

@_discord_408450936277565441:t2bot.iothaytan Set non-desktop=0 after you plug it in and switch it on if you want to see it appear as an extended desktop display 00:43:59
@_discord_408450936277565441:t2bot.iothaytan e.g. xrandr --output DisplayPort-2 --set non-desktop 0 00:45:06
@_discord_408450936277565441:t2bot.iothaytan That's probably taking the silence a bit too personally, and probably too soon too. People might just be too busy to do a detailed review of a board that requires some specialised knowledge, or the right people might just not have seen the post, or they did a quick scan and didn't see anything wrong so didn't comment 08:54:53
@_discord_408450936277565441:t2bot.iothaytan If it helps, I'm very impressed with how much you've learned and produced 08:55:22

@_discord_652643943829471252:t2bot.iojx35 Looking at it, there's nothing that should make the board not work - these are just nitpicks - which is what I suspect is the reason you didn't get any comments. I'd have a few suggestions for the schematic, but they'd be more of "here's how I do stuff"

I have some things on the PCB:
- (pic1) You should prefer to have the amount of copper coming out of both pads of small SMD parts balanced, so that during reflow, both pads heat up at a similar rate and the component doesn't tombstone. I'd expect JLC to handle this tho
- (pic2) The decoupling capacitors don't really make sense here. You have a lot of capacitance - 600uF at least - you really don't need that. The idea behind having multiple different capacitances is to have a small cap (both in size and capacitance) as close to each power pin as possible, I usually do 0402 1uF; and one or a few larger capacitors somewhere nearby. The smaller the capacitor (physically), the better it is at being a capacitor to higher frequencies. The larger bulk capacitors can deal with the lower frequency loads from some distance. (so C13 and C14 will do absolutely nothing; 0805 is unnecessarily big for them and they further from the pins than the bulk caps). Also having a via intersect a pad is ugly and would lead to problems in more extreme scenarios (it's a hole - it'll wick away solder if exposed)
- (pic3) CC lines don't carry significant loads, no need for a copper pour. FUSB302: VCONN should be connected to 5V, it uses that power source to send power to potential active cables. Which won't be the case with the PSVR2, so whatever
- Not sure why you went with 0805 parts, the vast majority didn't need to be so big, especially when you're making it for machine assembly anyway (I use 0603 when I'll be assembling by hand, which is most times, because it's way cheaper when I don't limit myself to basic parts)

I'd wait to see what's needed for the PSVR2 with the new firmware, it looks like the DP-aux section won't be needed

@_discord_652643943829471252:t2bot.iojx35 Yep, looking at other boards in the subreddit, there's usually something easy to point out, we've done that here already, I'd take the silence as a compliment. The board is absurdly impressive for a first design 08:56:55
@_discord_738643037512663072:t2bot.ioivry.vr Reddit is a hive of scum and villainy, where no one will hesitate to tell you you’re wrong, even if you’re not. I would take silence as positive. Regardless you’ve done an awesome job! 👍 10:18:26
@_discord_738643037512663072:t2bot.ioivry.vr Or try the Stack Exchange method, where you make incorrect comments via an alias and then use people’s desire to be correct to your benefit 😉 10:38:13
@_discord_709495567595864136:t2bot.iomrandtx LOL. Course, that kinda works everywhere, not just SE 😆 15:15:40
@_discord_408450936277565441:t2bot.iothaytan oh no it doesn't 15:44:38
@_discord_188950678721396736:t2bot.iosoloion Well, this sounds promising.

@_discord_408450936277565441:t2bot.iothaytan I wouldn't get a PSVR2 for use on Linux any time soon - we don't know how to make huge pieces of the headset work yet, or any idea about controller tracking 03:42:51
@_discord_188950678721396736:t2bot.iosoloion You would need a PS5 to get this firmware update anyway. Without one, there isn't much reason to get a PSVR2 for a PC.
I wonder if official support happens, will a PSN account will be required to use PSVR 2 on PC?
09:56:57
@_discord_738643037512663072:t2bot.ioivry.vr All the points made by others + you need a VirtualLink port or adapter. 13:20:53

@_discord_635168381971988490:t2bot.ioihc160 Is Sapphire AMD Radeon™ RX 7900 XT HDMI/Dual DP/USB-C https://amzn.eu/d/isIfNJw safe to use because everyone talks about the 6800 XT and not about the newer models? The headset was powered on with 12V from the USB-C port and booted. But it shows the GIF Scene to lock on the TV/Monitor and nothing more! 09:00:33

@_discord_652643943829471252:t2bot.iojx35 It's very unlikely the port can provide 12V 06:05:40
@_discord_652643943829471252:t2bot.iojx35 It needs 12V PD; and DP-alt mode with 2 pairs for USB3 and 2 lanes for DP. If it can provide 12V DP, it very well could work - my laptop does technically have PD output, but only 5V3A 17:50:15
@_discord_652643943829471252:t2bot.iojx35 Exactly. It advertises 5V3A when asked over USB-PD 17:58:50
