Thank you for being so understanding.

I don't think I have any power saving anything on. The only thing in the BIOS I touched was XMP, the hybrid mode on my PSU is turned off, and the monitor's eco modes are turned off.

I'm not sure what else it could be.

An observation and a question;

Furthermore, I have to turn both monitors on before powering on, this is due to some issue my GPU, MOBO, and screen all share, it causes a warning light to come on for some unknown reason. While this is not an 'issue' per say

You say the above is not an issue but what if it is in fact related to the flickering problem.

Using A and B for identification purposes.

Have you tried reversing the video connections to see if the problem is present when monitor A is connected to GPU video port B and monitor B is connected to GPU video port A.

I meant issue in a relative sense, meaning that it has been a normal action of my machine for a good long while, that being said, it could entirely be part of the same issue, I only noticed it once I swapped my monitor from two 75hz HP 27F 27" monitors to my current set.

Have you tried reversing the video connections to see if the problem is present when monitor A is connected to GPU video port B and monitor B is connected to GPU video port A.
Based on how this issue (the light included) persisted even with a single monitor (and did not change until I put a new GPU in, please see this thread), I do not think this will change the problem, but I will attempt to swap the cables on both the Monitor and GPU end and get back to you! (I feel an immediate update is in order so the thread does not get closed).

Thank you. :)

The suggestion was made based only on the info in this thread Pyro and from memory I seem to recall that you had me mark your previous thread as having been solved.

Fwiw, being that it only takes a matter of minutes to swap two cables around you could of actually done the test before you post your reply #25 ;)

That is correct, as Bruce suggested, I decided to take my lumps and call it good since I didn't notice any loss in performance.

I understand your point, but finding the time when I do not remember on startup has been more difficult than I expected, and I did not want the thread to be closed. :)

That being said, I did such, swapped the cables at the GPU, and still had the same flickering. For reference, I use the top (left most) DP out on my card, not sure if that would make a difference.

Never worry about a thread getting closed, let us know you will be busy and any thread can be marked as pending until a set date or closed and reopened by arrangement.

As the screens go it makes no difference but you have now confirmed that it is not a problem with either of the screens and have therefore made at least some progress, drivers are effectively ruled out else both screens would flicker so this leaves the GPU and the PSU.

Test both screens and each port that is available making notes on the outcome as you go, then, test one screen at a time in each of the ports on its own, again making a note of the results as you go.

If there is no flickering when there is only one screen attached you could ne looking at a power issue.

I didn't know that was an option, thank you.

Please hold for a report on this, I would like to go back to referring to the monitors as A & B for the left and right respective, if that's okay.

If there is no flickering when there is only one screen attached you could ne looking at a power issue.

You could be right, but I doubt it's a power issue, I have a 750W Platinum Seasonic, that should give me plenty 'head-room' to spare shouldn't it?

Do what you need to and in your own time, we are here to help and if kept in the loop beforehand we don`t mind delays between replies.

A very good PSU but a power setting or connection could be the cause, we will have a better idea once we know how testing the ports and screens individually goes.

You are welcome btw :)

I finally got that video of what exactly is happening (With the two monitors, not a single one), is it possible it's related to the G-Sync reminder? They seem to go hand-in-hand:

As for the single monitor tests, both did it albeit on a much short link, instead of this back and forth it was a quick flicker that took about a second or two. Of course, in typical tech fashion, when I tried to capture this on video, absolutely nothing. :rolleyes:

Hybrid is off, and my settings in Battery & Power along with Nvidia Control Panel are set to maximum power, are there any other possible settings?

Sorry but not used G-Sync so unable to comment on that, others may be able to help with that, that is a bad flicker though.

The main power setting to worry about is the Windows Power Plan, make sure that it is set to Balanced.

Balanced.

High Performance has caused so many people issues that I have a canned speech for it.

Power Profile
Active power scheme: High performance

Change the Windows Power Plan to Balanced, Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues and the setting should only be used for gaming type notebooks that have a discrete GPU that needs the extra power.

It may well not be the cause but regardless it should not be used on a desktop PC.

I'm not following with this, I checked it under 'Preferred plans'

Really? I never knew that, can I still safely change my sleep settings? (i.e. never)

The above is a canned speech that includes the power profile that Speccy detects, it saves typing out the same information over and over.

All my settings are at never and hibernation is disabled.

Ah, gotcha.

Awesome, thank you! I learned something new today. :D

Are there any other test or changes I can make to try and figure out what is causing this problem? Since I ran into the Q-LED issue I have been convinced my GPU is on the faulty side (I refuse to send it in, EVGA ships out refurb parts before even testing the ones sent in).

My motherboard was sent in and given the clean bill of health, and nothing else seems to be suffering or struggling.

Thanks again,

Couple of suggestions;

Try the GPU in the other two PCI-E slots on the MB.

Remove the GPU from the system altogether and use the integrated graphics to test.

You are welcome :)

I moved my graphics card to the second PCIE 16x slot, I will send another update after a night off and a fresh powerup. If the problem persists, I will also test the Motherboard alone.

Stay posted, thank you!
