So I have a BenQ XL2430T that I've been using for over a year now, with no issue. I use it mainly for CS:GO, and it's on for probably 20 hours a week, and off the rest of the week.
I got a Steam Link a couple of days ago (most likely not the issue, but it's part of the story), and was setting it up in my living room. It told me to go enter in a PIN into Steam on the computer. I went downstairs go to enter it in, and noticed that my monitor looked weird. It looked like if it was running in a lower resolution, but instead of it being fuzzy, it looked like every single row of pixels was shifted left or right randomly a couple of pixels. I had been using it earlier that day playing Shadow of the Tomb Raider, with no issues whatsoever. After entering in the code, I went into Display Settings and I think it was set to a lower resolution, so I set it to 1080p. Then, nothing. No display, no nothing. I Teamviewered into my PC from another computer, and I saw my desktop and everything seemed fine. Looking in Display Settings, Windows recognizes it as the XL2430T like it always has, but it says "This display is not active." Trying to activate it just results in it saying it can't activate it.
I have tried different DisplayPort cables, using HDMI, connecting to a different monitor using the same GPU and DisplayPort cable, and connecting from Mini DisplayPort to DisplayPort from my MacBook to the BenQ, and I've determined the DisplayPort connector on my monitor is just gone. It will "turn on" when plugged in, but it won't display anything, say "No signal detected" and go into standby mode. This happens no matter the DisplayPort cable or what it's plugged in to. I've tried power cycling it as one YouTube video suggested, and still nothing. HDMI works just fine, but only at 60Hz since the monitor doesn't support 144Hz over HDMI. I'm currently using DVI-DL for 144Hz, and while it works, I'm wondering if there's any way to diagnose or fix the issue. I work in an electronics repair shop, so I have no fear of tinkering around with it, but if it's not something fixable I would rather just use DVI-DL until I can replace the monitor.
Thanks again!
