Suddenly stopped at 240Hz
Suddenly stopped at 240Hz
You're dealing with an Alienware 240Hz monitor that's been stable for a year. It's now running at 144Hz after a recent shutdown. You've tried various solutions without success. It might be worth checking if the monitor is compatible with 144Hz or if there are any firmware updates available. Also, ensure the graphics card and cable are functioning properly. If issues persist, contacting Alienware support could be helpful.
I was experimenting with factory resetting the monitor and adjusting the dp cables connected to my graphics card. Suddenly, I noticed the 240hz option appeared. But now I’m having trouble getting it to work—every time I try, the monitor says no signal and I have to wait for the settings to revert to 144hz. I don’t know what’s happening.
It could be the monitor's panel if it's loose, or it might be a Windows problem—try connecting another monitor with the same refresh rate, but you might not have one available.
You seem to notice an unusual color depth setting, possibly affecting performance at lower frequencies. That might be the issue.
