DisplayPort is a computer connection format that delivers high performance display feature. You can connect your computer to a monitor with a DisplayPort cable for better display. However, it is possible that you have run into an issue where your monitor has no signal when your devices are connected via DisplayPort. In this case, you need a good fix to solve your problem. Aug 20, 2016 Displayport no signal after wake from sleep (things tried so far) A small update to my post (but without success so far): - tried the Framebuffer Edits for HD4600, no change - found some posts in Asus forums that possibly indicate that it is related to an Intel bug regarding power saving (see here, pointing to here).Applying these hints on a Gigabyte board is not working, because settings like.
Hi, I found a handful posts with the same problem, but no solution posted anywhere. My new monitor works great on the Displayport with a 4k resolution if coming from power-down, the resolution is recognized (audio not working yet, but I know there is a thread about HDMI audio I need to go through). But if I put the computer to sleep and wake it up again, the monitor notices it and powers up, but immediately says then 'no signal'. The only way to continue then is the power button.... I have a Gigabyte Z87X-UD4H board with onboard Displayport, no graphics card, with Mavericks 10.9.4 I tried Graphics enabler off and on, and set the motherboard BIOS setting to first use 'IGFX' (internal graphics), before it was set to the PCie. All that made no difference. Did anyone have the same problem and solved it? Thanks, Toni
On April 30th Microsoft released a large update to Windows 10 known as the ‘Windows 10 April 2018 Update’. Since the release, we have had a handful of reports from customers using our Thunderbolt 3 docking stations (such as the TBT3-UDV and TBT3-UD1-83) that after the update the dock’s video outputs would continue to work, but the dock’s USB ports, Ethernet port or audio port would stop functioning. (Note that this behavior can happen with all brands of Thunderbolt devices, and is not specific to Plugable devices.)
In all the cases we have seen so far, the cause was determined to be that the Thunderbolt device lost its authentication status in Windows during the OS update. To expand further, in Windows there are security measures in place which require Thunderbolt 3 devices to be authenticated or ‘approved’ before certain elements will function. While video outputs will always function regardless of authentication status, the USB ports, Ethernet port and audio port will not work if they are not properly authenticated.
If things stop working as expected, the best path forward is to uninstall and reinstall the Intel Thunderbolt software (with an updated version if available) to help ensure that the Intel Thunderbolt software that controls the authentication process is in a good state. To do so, follow the steps below:
1. Disconnect the Plugable Thunderbolt 3 dock from the system and remove its power cable so it turns off completely. Please keep it disconnected until prompted. 2. Uninstall the Intel ‘Thunderbolt Software’ present on your system via the Control Panel -> Programs and Features. 3. Restart the system, even if not prompted. 4. Download and install the latest version of the Intel Thunderbolt Software published by your system manufacturer. If you are unable to obtain this download from your system manufacturer, you can download a version directly from Intel here ->https://downloadcenter.intel.com/download/28658/Thunderbolt-3-Driver-for-Windows-10-for-Intel-NUC-Products 5. Restart the system once again, even if not prompted. 6. Reconnect the power cable to the Plugable Thunderbolt 3 dock, and then reconnect the Thunderbolt 3 cable from the dock to your system. 7. You should be prompted to authenticate/approve the dock, similar to what we show here ->https://plugable.com/products/tbt3-udv#Authenticate Please approve the device as shown in the example using the ‘Always Connect’ option. * There is a chance the approval prompt will not pop-up automatically. If that is the case please just proceed with the next step for now. * 8. Please test any non-functioning ports in the dock again.
