Ultrawide no longer works with DisplayPort cable after just one week of use.
Ultrawide no longer works with DisplayPort cable after just one week of use.
You have an MSI Ultrawide that stopped working recently. After turning off the Xbox controller, the screen went black and then showed no signal. After unplugging the GPU and plugging it back in briefly, it worked for a moment before going white and then black after a minute. HDMI is functioning correctly, and the 1 DP port works when connected to a Mac. Using a different monitor (1920x1080, 144Hz) with the same cable resolved the issue. In Device Manager, you removed the GPU drivers and reinstalled them without success. The display sometimes shows a higher resolution (3480x2160 vs native 3440x1440), causing blurriness. This behavior is unusual. The video linked may help clarify what’s happening with your monitor. Your PC specs are: AMD Ryzen 5 5600, RX 6600, 16GB RAM, DDR4, 3200MHz.
It appears the connection is inconsistent, sometimes functioning and other times not. I’d just replace it with a fresh cable.
It might be possible the cable supports the reduced resolution but struggles with the ultra-wide format. Regarding the odd HDMI resolution problem, adjusting the display settings through the AMD interface could likely resolve it.
No special settings were applied, so the issue remains unchanged with an unusual error occurring.
Cable may fail unexpectedly. After three years and a month, connections stopped working. Even if it still functions slightly, it might be too damaged to handle the required resistance and frequency.
