XENEON 32UHD144, fw v. 0.08 – any means to disable “Deep Sleep”?

Gigabyte Aorus Master B550 -- BIOS F15e (also tried ‘b’ and ‘d’)

Ryzen 5800X3D

Geforce 4090 {MSI Gaming}

XENEON 32UHD144, fw v. 0.08

 

 

In jist, there’s no display output on POST during “reboots”. This is observed via DisplayPort {across a variety of different cables and all ports of the card}. On cold-starts where the system is left off and the monitor is allowed to fully enter standby ‘first’, it works correctly and comes up with a POST every-time.

{in otherwords, I cannot enter the BIOS or see the OS startup unless I cold-start the system}

 

 

Whenever I just reboot, the standby prompt is shown – times out, the monitor enters standby – post beep goes off (slightly after this point), and the monitor never comes back on until the system enters an OS {loads display drivers}. For instance, in safe-mode, there’ll just never be a screen shown. Same behavior is observed on CSM and UEFI, whereas other monitors that I own seem to work correctly.
 

It’s worth noting that I've tried a 2080 Ti {in the same machine} and it behaves correctly -- there’s always a POST display on it. I have also tried flashing NVidia’s UEFI vBIOS update, and tried contacting NVidia for support. Their suggestion was disabling Deep Sleep on the display.  Unfortunately, I can find no such setting (either through iCUE or the monitor's menus).

 

-- Is there any setting that I’m overlooking for “Deep Sleep” that I can disable, or other hidden service menus for this display?

Thanks!

Take it that the answer on this one is a "no".  So I'll refine the question, given that I've tried HDMI 2.1 -- and that has its own set of issues it seems.

-- On HDMI to the 4090 the display comes up on POST consistently..  However, every time that the monitor enters standby, it instantly leaves standby --followed by two back to back device detection chimes.  {aka, the OS automatic display timeout does not function anymore}  On DP, this is only a single chime triggered on leaving standby.

 

Is the ability to disable Deep Sleep (always present EDID) a feature that Corsair can potentially add down the road in a firmware update?  If not, does anyone have experience with products such as the "Dr HDMI 8K" on the Xeneon lineup?  (or any other device that can sustain EDID)

I'm having a similar issue. If I change something in the BIOS on my Motherboard like a frequency or timing then save and exit my monitor 95% of the time fails to detect either a DP or HDMI signal.  All i see is the monitor LED fluctuate between orange and white thus leaving me with a brick. By hooking up another monitor which works perfectly I can get the XENEON to work properly until the next time I change the BIOS.

Do you see on the monitor when booting a no signal message?

Pretty much, no-signal, monitor standby.  Though for myself personally, it's on any reboot of the system.  That can be on an exit of BIOS that touches processor settings and causes a reboot -- or on simply choosing "Restart" from Windows. I will get display signal if I just power off the system, let the display enter standby, then power it back on {cold start}. [trying to train myself to "never reboot"]

 

It's worth mentioning that the Xeneon display also takes a really long time to come out of standby.  On cold starts of the machine, I will never see the post display unless I raise the post timeout to 20+ seconds or hit pause / break.  It takes about 10-15 seconds for the display to come on even with cold-starts.

Update-- Tried two devices to persist monitor connection state to the GPU:

DisplayPort Hotplug Maintainer  (DP-HP-MNTR-SRC), 230$:  Display comes up 100% of the time on post with resets, but this seems to impact signal quality, and no matter the cable that I use in conjunction with it -- the screen will black out intermittently when running at 4K 144hz.

 

DrHDMI 8K, 199$:  Display comes up 100% of the time, and does not randomly lose signal at 4K 144hz w/ freesync.  Unfortunately it seems that I lose the ability to run HDR, no matter the EDID settings combo in the device's web-CP.

 

The DrHDMI device has the ability to be re-flashed, so I will reach out to their support.  ... Sure wish Corsair would lend a hand here though, it's a shame to be seeking products to solve a problem that no other monitor in this price-class seems to have.

8 months later update:  I've since replaced my motherboard with an ASUS X670E-E {coupled with 7800X3D}, RMA'd the graphics card -- same problem --, and finally replaced my MSI 4090 with an ASUS (at a loss) -- due to TPU users being convinced this was isolated to MSI.  (it's not)

 

Contact with NVidia and DrHDMI support has gone silent {no fix}.  Is this end of the line / time to sell the monitor {feels like it}?  Doesn't seem Corsair is pushing updates, and support similarly has gone cold.  Neither MSI nor ASUS provided any support, everyone is just pointing the blame at everyone else.

--I've gone back to my old display for the last several months due to having to 'hard power' the machine when it gets stuck during boot (because I can't see what Windows is doing until drivers are loaded).

 

Figure one last bump here in hopes of reaching someone.  Feeling pretty betrayed as a fan of the Corsair brand.

Hey,

Just chiming in to say, I have the same issue. I've been pulling my hair out thinking it was an issue with my new build and it turns out that it was the monitor. No matter what I did, I couldn't get this thing to go into BIOS if I disabled the iGPU. I'm guessing due to, "deep sleep" the monitor misses the DP handshake and the GPU assumes no display is connected. Out of curiosity I connected my old monitor and it went straight into BIOS 100% of the time. So, that's how I narrowed it down to this monitor.

A trick I've found is to turn the monitor off and wait like.. 15ish seconds(or in my case until my USB DAC makes my speakers thud) and turn it back on and it should actually handshake with the GPU and  let you into the BIOS.

This monitor is absolutely beautiful and I'm stuck with it because my eyes are super sensitive to KSF, which rules out pretty much anything that isn't an OLED. It's just a shame the firmware is half baked.

Oh... and my rig has the bonus feature of disconnecting the graphics card whenever the monitor goes into, "deep sleep". So, I get the hardware disconnect/connect noise every 30ish seconds once the monitor goes idle and turns off.

 Come on Corsair, you have been made aware of these issues (I have exactly the same and have set my system to slow boot, but no screen shows up until I remove the DP or HDMI from my RTX3090)  I am using ICUE software, but there is no firmware update.  This monitor is now about a year on the market, surely Corsair is aware of these issues and if there is no resolution to this I will have to RMA my monitor.  There are plenty of good monitors in this class at the same price point.

Make sure that you go through the hoops with support if you've not already...  You'll likely wind up with the silent treatment like I have [dead end], yet nagging them is apparently the only way that we're ever going to get this addressed.

I'd also like to echo that point that there are other monitors of similar specs in the game price class.  All of those monitors (the alternate choices / the competition), have the ability to disable Deep Sleep, and DO NOT have the blank post display issue that the Xeneon does.  I've infact already replaced my monitor and given up on ever using my Xeneon ... which just sits in a closet at this point.

 

Reviewers may be giving Corsair a pass ... which I honestly do not understand at all.  Yet it's a SEVERE problem to not see the display until an OS is loaded and drivers are loaded.  Eventually every computer user will wind up in a situation that they either need to install an OS, access BIOS, or heaven forbid that something breaks / goes wrong.  I literally was corrupting my install, because I was shutting off the machine in the middle of a check disk {requiring input that I could not see}.

-- If you're still in the return window, I'd seriously consider it unless support gives you an in-writing confirmation that a fix will come.

I'll do my part in bumping this yet again.
