I attempted to increase the speed of both my monitors, but only one is working now.
I attempted to increase the speed of both my monitors, but only one is working now.
So I got my new monitor last night and connected it with the other one, everything worked just fine. I decided to push both of my Dell SE2717H models up to 70Hz from their default 60Hz. It ran smoothly all night, but when I turned on the computer the next morning, it booted into Windows and then went black. I had to reset it, unplug one monitor, and eventually it worked again. I reached out to Nvidia, they tried but referred me to the monitor maker. Then I called Dell, who also couldn’t help. If anyone could assist, that would be a huge relief. I ended up getting a new monitor and an early Christmas gift, but it’s frustrating not being able to use it.
I'm not sure if I'm understanding all the details correctly.
Does each monitor function independently when it's the only one connected?
Are there variations depending on whether a monitor is linked to the GPU or the motherboard?
In other words, just verifying that each monitor operates alone—without both being active together on the GPU and/or motherboard.
Two monitors might be putting too much strain on the PSu through the GPU.
It seems it worked until something failed.
If everything runs smoothly at 60Hz, 70Hz could be pushing limits.
It's linked to the GPU, but there seems to be no distinction there.
The displays function independently rather than collectively.
This might be the issue, yet it doesn't clarify why the entire system operated smoothly the previous night.
It would work by simply turning off the PC and having the settings take effect at startup. I’d undo the overclock on both monitors to check if functionality returns. Unstable overclocking is a problem, especially with dual monitors. It might be that the second monitor’s settings are corrupted. Just proceed carefully—monitor performance can drop when refresh rates increase.
