Acer monitor black screen blue light12/28/2023 ![]() On specific devices, you can wake up the screen by pressing the volume up and volume down buttons at the same time three times (quickly). The "Windows key + Ctrl + Shift + B" keyboard shortcut can restart the video driver and refresh the connection with the monitor. ![]() You can also try connecting the monitor to a different computer or using a different video cable to determine whether you are dealing with a broken display, graphics card, or damaged cable.Ī black screen could also happen because Windows 10 will lose its connection with the display. Typically, you will need to press the Function (Fn) key and one of the functions keys like F8 or F10. If the problem occurs on a laptop, use the function key on the keyboard to increase the display brightness. (You may need to check the manufacturer support website for specific details.) It's also a good idea to check the monitor is using the correct input. When you connect to an external monitor, open the control panel on the display to increase the brightness to resolve the black screen problem. In the case that you recently updated the UEFI (Unified Extensible Firmware Interface) or BIOS (Basic Input/Output System), this can sometimes disable the discrete graphics card, which you can only enable again from the motherboard firmware. It is frustrating when I go to present a design to a customer and they can’t see it exactly as it shows up on my monitor.If the device has both a discrete and integrated graphics card, you can try switching to the integrated video card to determine whether the discrete card is the problem. I may modify some design decisions now that I understand why this is happening. These screens have the same difficulty displaying light gray colors in the F range. This makes design really challenging.Īnother thing to note, our company recently installed large television screens in our conference rooms and we connect to them instead of using projectors. Unfortunately, I’m not finding a workaround that works for me because my control panels don’t have the options mentioned, but I’m still hopeful. See this article for reference and a potential workaround. The reason is because my monitor is connected via an HDMI cable, and this forces the display into RGB Limited mode which has a limited color range from 16 to 235 (instead of 0 to 255). I find myself constantly dragging windows from my external monitor to my laptop’s native display to confirm color values. As I design using light gray colors in the F range, they all show up as white on my external display. I have been troubleshooting a similar issue today and thought I’d mention what might be causing the issue. ![]() The only realistic fix, unfortunately, would have been to darken the background color, which means adjusting the font color as well to satisfy contrast accessibility requirements, as well as (possibly extensive) cross-browser and device compatibility testing to determine the “minimum visible gray.” For us, it just wasn’t worth the effort. ![]() Whether or not it does depends entirely on the quality and settings of the individual display.įor us, it wasn’t a huge problem as these reports are meant to be printed, so we didn’t take any steps to fix the issue. So long as you’re using any sufficiently light shade of gray, you’ll run the risk of this happening. We ended up adjusting her monitor contrast and the issue resolved. This showed fine on my computer, but our QA tester wasn’t able to see the zebra striping at all, despite confirming it was coded correctly. I designed a set of custom reports recently that used a similar gray as a background for zebra striping rows (we used #f2f2f2, and it looks like you’re using a slightly lighter #f5f5f5). I can say with very good certainty, then, that it’s almost undoubtedly a monitor contrast setting, rather than anything you’re doing on your end.
