Samsung G7 Odyssey Black Screen

[MBRenegade]

So my 27" G7 seems to be having an issue where the screen will go black randomly and seemingly for no reason, IT DOESNT FLICKER, it goes black and stays black (backlight still on, OSD unavailable). The ONLY way I have found to solve the issue is to hold the power button down for 5-6 seconds which seemingly resets the monitor as all my settings are then lost (or turning it off and back on by unplugging the power).

I have only noticed the screen going black when gaming or watching Youtube 😕

I really hope there is a fix out there as I dont want to have to go through the hassle of sending it back and then waiting for a replacement, especially when Samsung Customer Support have already told me this can take 2 weeks total (out of stock atm so god knows how long it would actually take). I am also working from home due to lockdown and its my only monitor currently. If there isnt a fix and my only option is to send it back, I will likely just refund and find another monitor, which I dont want to do either as I really like this one (when it works lol).

I am running an older build PC (6700k, GTX 980 Ti, 16GB RAM) so dont know if this maybe has something to do with it? I have a new build sat next to me but waiting for a 3080 so unfortunately I cant test my theory.

So far I have tried:

• Praying to Lord Gaben
• 2 different DP cables
• HDMI
• All Ports
• Firmware is updated
• Nvidia Drivers are up to date
• Windows is up to date
• Monitor drivers are installed
• Adaptive Sync Off
• Fully resetting the monitor, uninstalling drivers etc.
• HDR is not turned on (not available on my GPU anyway)
• As I am writing this I have found out about a firmware update for my GPU that supposedly solves an issue on my GPU with DisplayPort 1.3/1.4, I havent tested this yet. - Although I did also try changing the DP version on the Monitor to 1.2 with no luck. **UPDATE - Didnt work!

Thanks in advance to anyone that gives me advice or anything else to try that I may have missed.

I wanne bump this issue.
I have exaclty the same problem. I have it when playing Apex Legend . After 30 minutes (when monitor temps gets higher ) the monitor goes black , no OCD  and to revive i need unplug the powercord.

 I made a video of it : https://youtu.be/onGsI9r1zV0

I have got it rma'd.
I printed this topic for them to help with the problem and how to fix it . They did not replicate the problem, ( they did the test with hdmi and 60hz on a laptop!!) 
But they preventive replaced the motherboard and updated to latest firmware (it was already on 1014 with old mobo)

Yesterday i got it back and started Apex legend. Unfortunately, black screen is still there when heated up. It is actually even WORSE!. I have it sometimes with 144hz enable and watching youtube!

Im getting sick of this monitor. I don't want it anymore because this monitor is bad by design!

Ive got samsung support from whatsapp but they response is non-existent.
The only thing i want is a refund. What are the steps i need to do?

Same issues as above. I now have a desktop fan pointed to the back of the monitor because it seems as if it may be a heat issue. I saw a post on reddit where this man "fixed" his issue by removing the plastic cover in the back and mounting a 120mm to the metal post. https://www.reddit.com/r/Monitors/comments/t9eu5s/i_just_fixed_my_g7_odyssey_black_screen_problem/

Hey Guys,  Just wanted to let you know .Samsung gave me a new G7 27inch and for now i don't have any black screen issue anymore. The back of the screen isn't even warm after a full day of stress testing. (it was hot with my last G7).

note: i needed allot of reference to get that (forumpost, my own youtube video etc....)

I just realised I never updated this thread.
I had to send my monitor back for repair around 4 times, the repair company got so annoyed at samsung making me send it back for repair they just ended up replacing everything in my monitor, basically giving me a new one. Though up until the final repair I believe the panel itself was the only thing they had not replaced, so the issue could just be faulty panels.

I found ways to reliably replicate it using Youtube, gaming and even just browing certain websites however whenever Samsung tested it they didnt use the same settings I told them about either.

Sounds like Samsung made you jump through all the hoops I had to, It was rediculous, however I have had no issues with my monitor since. Though I was without a monitor for almost 2 months within the first 4 months of owning it due to Samsung saying my only option was repair.  

Due to how shocking Samsung customer service was I wont be buying from them again, nor recommending them.

Nah. From my observations it would overheat if brightness was set to more than ca. 70. Probably it was making more heat than light above some threshold. What happened is they've cut the max. brightness with newest firmware. Nobody will re-review a year old monitor...
