Previously, when I'd turn the 1 monitor off, the 2 monitor would flicker, and reset itself as primary. At this point, the mouse pointer was contained on the monitor. Now, out of nowhere, when I turn it off, the mouse pointer will still go off screen to monitor 1.
So just today, I have this problem where my monitors does not display anything after start up. I would turn on the CPU and everything runs fine (fans, power supply, etc) but my monitors stay undetected as if my computer was never turned on.
Are you getting post beeps on startup ? If not you may be dealing with a power issue . Just because your fans are running and your motherboard light comes on doesn't mean you have enough power in the power supply to run the machine .Power supplies can die slowly and still appear ok .If you have access to another power supply try changing it out . You may also want to try a different monitor or test your old monitor on another computer. depending on your motherboard you could try resetting the mem button common on Asus boards. Also you mentioned you've disconnected the power and that you've held down the power button for extended periods . Did you do this together? if not try unplugging from power and holding the power button down for roughly 60sec then plugging in and rebooting. Finally as dumb as this is going to sound but it happens to the best of us... is your monitor turned on and plugged in? Just sayin Hope something here helps and good luck
@jayeff there are 2 different issues here, but the symptoms are the same. One is purely a hardware issue(RAM, PSU cables and other) the ohter one is a software issue. Iv'e eaten my nails over this. I swapped everything, mobo, psu, monitor, gpu, cpu bios update etc.. all of it and was still experiencing this when the system needed to auto reboot, for an update for example. NOTHING WORKED. The only thing that remained unchanged was Win10. This change in power options has worked for me. Finally..
If your motherboard has an onboard graphics card you might want to try unplugging your PCI-E graphics card and plugging a monitor into the onboard graphics card. This will verify whether or not it is your PCI-E graphics card that is faulty or not.
I have had similar problems - main monitors not lighting up - BUT this morning after reseating graphics card etc - still nothing - I then turned the monitor - which was ON, turned it OFF, and after a couple of tries it DID show the screen and allowed me to log -i n
Open your PC case and locate your video card. Remove the card and then replace it firmly in its slot or, if possible, insert the video card into another slot on your motherboard. A video card that is not making a firm connection will not display images to the monitor. Close your PC case and test the monitor again.
If you turn on personal results for your Smart Display, you will automatically see personal results like upcoming calendar events and commute info, as well as personalized YouTube video recommendations, on your home screen and as notifications. Anyone near the device can see, tap, and act on them.
The DXGKARG_COMMITVIDPN_FLAGS structure stores information that the display miniport driver can use to determine how to respond to requested mode changes. With this information, the driver can distinguish between mode changes that occur during regular activity because an application requested a mode change, changes that occur because of power transitions, and changes that occur while monitors are turned off.
If monitors are being turned off or turned on, PathPowerTransition will be TRUE to indicate a power transition. In this case, a common pattern is that the monitors will be turned off, and then at some later time, the original configuration will be restored. It can be a significant workload for the driver to reset the display configuration completely after a system shutdown. Additionally, , the driver must continue to complete DxgkDdiPresent operations while the monitors are turned off. However, the driver can reduce its workload when a call is made to DxgkDdiCommitVidPn by making sure that the involved monitors are powered off. When power is restored, the driver workload to restore the display configuration will thereby be reduced.
Because the monitor might not be physically connected (at system resume time, for example), the driver should not rely on Windows to make a later call to the DxgkDdiSetPowerState function to set the power state of the child device of the display adapter. However, Windows will still request that the CRTC is to be turned on. If the driver does not turn on vertical sync when it is requested to do so by the display mode manager (DMM), and if the user later reconnects the monitor, the monitor display might be blank.
DxgkDdiPresent operations must still be honored by the driver while monitors are turned off. The driver might have to act upon a mode change triggered by an application, for example to perform modifications to the rendering pipeline to account for rotation changes. Settings of PathPowerTransition = FALSE and PathPoweredOff = TRUE inform the driver that such a mode change has occurred. In this case, the driver must not turn on the monitors, but instead it should reprogram the hardware, if it is necessary, to accommodate the mode change so that additional DxgkDdiPresent operations can be completed. When such a mode change has been performed, and monitors are later turned back on, it is unlikely that the mode that occurred before the power down will be restored.
If a system resume operation is triggered after monitors were turned off for a system suspend operation, the driver can receive a DxgkDdiCommitVidPn call with both PathPowerTransition = FALSE and PathPoweredOff = FALSE before a DxgkDdiCommitVidPn call is made with PathPowerTransition = TRUE. This situation should only occur with an empty topology and, in this case, the driver should not turn monitors back on because the power transition is not yet completed.
If a test has been completed, the system status will be reported "ready." An uncompleted test will be reported "not ready." An OBDII vehicle will not pass the annual inspection unless the required monitors are "ready." The Vehicle Inspection Report from the test equipment will identify monitors that are not ready.
To allow your vehicle's monitors to perform their tests and reset them to a "ready" state, your vehicle will have to be driven in a special way called a "drive cycle." Running through the drive cycle sets the readiness monitors so they can detect any emissions failures. Your vehicle's specific drive cycle can depend on the vehicle make and model, and which monitor needs to be reset. In most cases, two drive cycles are required, separated by a cool down period.
If the only reason your vehicle failed the inspection was due to readiness monitors not being in a "ready" state, and your current inspection has already expired, the inspection software will issue a 10-day extension that will allow you to legally operate your vehicle on the highways. During those ten days, you can either:
The purpose of the OBDII drive cycle is to run your vehicle's onboard diagnostics. This, in turn, allows monitors to operate and detect potential malfunctions of your vehicle's emission system. The correct drive cycle for your vehicle can vary greatly, depending on the vehicle model and the monitors that need to be reset. When a specific drive cycle is not known, or drive cycle information is not available from an owner's manual, the generic cycle described below may assist with resetting your vehicle's monitors. However, this generic cycle may not work for all vehicles.

Regardless of which version you have, whether it's the iPhone 14 Pro/14 Pro Max or the iPhone 15 Pro/15 Pro Max, the steps for turning off the always-on display are the same. The always-on display will be turned on by default when you first set up your phone, so if you want to turn it off, you can do so as soon as you're able to unlock your device.
Sometimes, I want to listen to streams or videos while I'm on the go, but I can't put my phone in my pocket because that would press buttons on the display. Is there any way to turn the screen off and still let the stream/video running like it does with music players?
I turned off automatic brightness adjusting in the display preference pane (as explained here). The brightness still adjusts automatically. If I have the preference pane open I can even watch the slider moving to the right. Is this a bug? I would like to set the display to a lower brightness to save battery.
