How does that help me in any way? Obviously anyone would already know that & I already do that. I have always bought my Icrons from KVM Australia which is one of their official dealers, but as I said, my friend bought from Ebay so we really want to know a way to tell if it's genuine Icron or if she got ripped off. It's really hard for us to tell, the Icron 3251C-10 isn't exactly cheap. I have it in front of me & everything "looks" legit, the packaging, the extenders themselves, the stickers, the cable etc.

Hi. I have a few Icron extenders, USB over ethernet etc which I love. Never had any issues, they always work as advertised (as I've tried a few other brands & didn't have a good experience) & the important part, they're "Made In Canada". Well at least they USED to be. I've always bought Icrons brand new but recently my friend wanted a few Icrons, & found some on ebay. But when she showed the pics of them, the sticker on their backs says "Designed In Canada, Made In China". I said WHAT! & automatically told her they're not genuine Icron extenders but China copys instead. But I noticed too many of them on Ebay etc had this "Designed In Canada, Made In China" & I emailed Icron asking if any of their products are made in China? I found out sadly in 2019 Icron was bought out by Maxim Integrated & not long after that all Icron products starting getting made in China & not Canada anymore. Now it's too hard for us to tell what's genuine Icron & what isn't. Confidence goes down when shopping. After I told my friend she just took the plunge & bought 1 for now. Still waiting for delivery. So my question is, does anybody know a way to 100% confirm if it's genuine Icron or not? Even a way to tell by just looking at ebay listing pics? Cheers.

Wait I don't understand... Do you mean you bought a cheap used 450W power supply? Did it arrive & you tested with this other PSU & the problem is still the same? ((Woah WTF why is that smiley face I quoted sooo huuge lol!!))

If you have a spare PSU try it, I know it's hassles but definitely worth the test. I know you said it's less than 4 months old but really doesn't rule it out for sure. There's people that have bought good quality PSU's brand new & have fails in all time frames, days, weeks, months & even cases of people getting delivered PSU's that don't even work from the very start lol. Pretty reputable companies too, sure it's rare but does happen. Also I know you stress tested your PC for 10 minutes but PSU's can act very funny when problematic or failing, I wouldn't rule it out.

It's really about your budget situation right now, I mean if you're going ok with cash & you want the piece of mind of a new PSU then go for it, or you can save that money for something else & push it to 10 years keeping in mind that if you start experiencing weird random problems down the road that it could be your PSU. What PSU are you using right now? Also video/display related problems.... if I had to pick out of BIOS or Windows 11 I'd definitely say it's Windows 11 related.

Yea try some steps & get back to us. Even try a different display port on your graphics card & HDMI after that just to test. I wouldn't think this problem would be BIOS related at all but then again, it is the computer world. Have you changed ANYTHING lately with your setup? Hardware or software or cables? Hopefully you get it sorted.

Have you tried simple stuff first like trying another cable? Have you got a spare monitor you can try on? Or a TV to try on? Has your PC always been like this or this just started recently? Does this also happen on Windows 10? Does this happen when using HDMI?

xg32 thanks for your reply. I literally mean no offense but you're really making up your mind on something that you're obviously unaware of the actual specs or haven't really checked out the latest specs which I don't blame you because you have Display ports as your main. I don't know how long it's been since you've bought a top of the range TV rather than just a gaming monitor but things have changed dramatically in the last year or so & the line between monitors & TV's has never been so blurry. HDMI 2.1 has VRR which is equivalent to Gsync Free Sync etc, QFT Quick Frame Transport which talks to GPU's with a frame by frame basis so there isn't input lag such as older TV's as manufacturers finally realize the gaming market, native 10-bit 4k panels, there's 8K tv's even, HDMI 2.1 even supports up to 10K these days, dynamic HDR10+, there's nothing missing from latest model top brand TV's anymore. 12-bit IS really 12-bit, why is that hard to believe for you? Even Dolby Vision is natively 12-bit uncompressed & has been for a while.When you output a color depth that is above what your display can do then the display dithers the 12-bit down to your display's native bit-depth, in my case when I output 12-bit, my display dithers it down to 10-bit. I'm not sure why you're stuck at the 12-bit anyway, you haven't read my post clearly at all. Why would you say my cap is effectively 8-bit 50Hz & that it wouldn't happen on a display port, are you living in a cave?? You seriously think HDMI is "capped" at 8-bit 50Hz ? I said I can output 10-bit 50Hz but it's just the uncompressed 4:4:4 that it won't let me do. I don't even have the latest HDMI version. I even said I can output 12-bit @ 30Hz no problem, so not sure why you'd say that other than just skimming through my post & not reading properly.

Well as I said 12-bit & 8-bit do show up AND do work on my display when I either do 30Hz or 50Hz with 4:2:2 output. Also I CAN do 10-bit 50Hz but only at 4:2:2 not at 4:4:4 which is exactly my issue here, trying to output 4k RGB/YCbCr 4:4:4 10-bit @ 50Hz as my displays HDMI supports this signal 1000%. Also let's not forget my friend who has the exact same issue with a different 4k 10-bit display & Nvidia control panel outputting this signal. Even if I had a display port, there's no reason I can find why I'm unable to output this signal with my HDMI other than Nvidia's control panel. Thanks for your reply.

Turtle Rig lol thanks for taking the time to read my post, I just wanted to give as much info about my issue as possible. I don't have a 30Hz issue & don't get any limitations when on 30Hz with HDMI. The ONLY weird thing that happens when I try 30Hz is that 10-bit isn't listed even though my display is natively 10-bit (not 8+2 bit dithering), the only modes that are listed are 8-bit & 12-bit which both work fine. Also please know that I don't plan on leaving anything on 30Hz YUCK, just curious why there's no 10-bit as it just adds to my confusion. Also 50Hz through HDMI is not odd at all. With version HDMI 2.0b I should be able to do 4k RGB or YCbCr 4:4:4 10-bit @ 50Hz. Only HDMI "2.1" can do 4k RGB or YCbCr 4:4:4 10-bit @ "60Hz". I can output 4k RGB\YCbCr "4:2:2" 10-bit chroma subsampling @ 50Hz or 60Hz no problem. But if I want to keep my uncompressed 4:4:4 signal with my HDMI 2.0b at 10-bit then my only highest refresh rate possible is the 50Hz that I'm trying to get to work. Regarding HDMI & DisplayPort, my display doesn't have a DisplayPort, if I get a DisplayPort to HDMI cable, won't I be getting the exact same result anyways because my display's side is only HDMI ports?? I don't have a cable otherwise I'd quickly try but I'll borrow off a friend. Yea it's a good cable & Premium HDMI certified 18Gb/s with a QR code I can scan to confirm the testing. On top of this my friend has the exact same issue as me with a different brand good quality cable at only 2 meters even! Another reason why it's not the cable is that the cable lets me output 4k YCbCr 4:2:2 10-bit @ 60Hz (even 12-bit!) which is 15.68Gb/s bandwidth. The RGB/YCbCr 4:4:4 10-bit @ "50Hz" signal I'm having issue outputting only needs 13Gb/s bandwidth, so my cable does 15.68Gb/s signal fine & a 13Gb/s signal I'm going for shouldn't be a problem. Yes ofcourse, that's what I'm stuck on, RGB\YCbCr 4:4:4 with 4k 8-bit @ 60Hz, I'm trying to output RGB\YCbCr 4:4:4 with 4k "10-bit @ 50Hz", it's a HUGE jump from 8-bit max possible colors of 160 million compared to 10-bit's max possible colors of 1 billion. The Quadro lineup difference compared to normal is that the Quadros can do 10-bit + in OpenGL and Direct3D whereas the normal lineup of graphics cards such as mine can do 10-bit+ but only in Direct3D (games). For Windows that's how it is anyways not sure about Macs & Linux. Thanks for your replies appreciate it.

Hi all. I couldn't find an official Nvidia technical support email which is ridiculous, all I found was an online chat which just kept me waiting forever, so I'll try my luck here. I have an ASUS NVIDIA GTX 1080 hooked up HDMI, latest drivers. The Nvidia Control Panel won't let me output RGB or YCbCr 4:4:4 at 10-bit "50Hz" & I just can't understand why. I'm fully aware of the HDMI 2.0, 2.0a & 2.0b specs & limitations, according to the HDMI chart, I know ofcourse I cannot output RGB or YCbCr 4:4:4 10-bit "60Hz" due to bandwidth limitations of HDMI 2.0-2.0b, but it clearly states I should have no problem outputting this RGB or YCbCr 4:4:4 10-bit "50Hz" signal so I'm not sure what's going on. Maybe I've missed or overlooked something which is why I'm here for help. HDMI 2.0-2.0b bandwidth is 14.4 Gbit/s, the HDMI bandwidth needed for outputting my RGB or YCbCr 4:4:4 10-bit "50Hz" signal is 13.00 Gbit/s. My 1080 is HDMI 2.0b & my Panasonic OLED HDMI ports are full bandwidth HDMI 2.0b & is a native 10-bit HDR10 panel. My HDMI cable is a Certified Premium High Speed Cable with the QR code to scan & confirm etc which is tested at 18 Gbit/s. So why won't it allow me to output my signal even though the bandwidth is definitely there ?? The weirder thing is if I set Nvidia to output at 30Hz, then it allows me the choices of RGB 8-bit or 12-bit only (no 10-bit) OR YCbCr 4:4:4 8-bit or 12-bit (again no 10-bit) & it actually does output these signals fine & stays when I apply them. Why would the native 10-bit depth of my panel be missing from the Nvidia output options at 30Hz yet it shows me 12-bit ?? Not that I intend to go down to 30Hz but it really adds to the confusion. My friend has a Nvidia 970 which is HDMI 2.0 & his panel is also HDMI 2.0 so he's in the same HDMI boat as me & even he has this exact same issue, cannot output RGB or YCbCr 4:4:4 10-bit "50Hz", also like me when he changes his refresh rate to 30Hz for curiousity, he too can only choose from 8-bit & 12-bit with 10-bit missing for both RGB & YCbCr. So 2 main questions really. Why is Nvidia Control Panel not letting us output RGB or YCbCr 4:4:4 10-bit @ "50Hz" with HDMI 2.0?? Also why is it only letting us choose between 8-bit & 12-bit on 30Hz without my native 10-bit listed? Are these driver issues ?? Thanks for your time, Ash.
