problem with 2 screen display
Posted on 9/7/23 at 10:02 am
Posted on 9/7/23 at 10:02 am
Need some help....At work I have a Dell laptop (with intel core 15 vpro processor) and I display on the laptop screen and on another Dell desktop screen. I have split screen with different content on the 2 screens. The 2nd screen will lose display transiently (<5 sec) all the time. the 2 screen config might work properly for 1 min or it could be 1 hour and it shuts itself off and resets then I have to drag what I had on the desktop screen back over to it. Rinse and repeat. My IT "experts" at the govt agency I work for have no clue.
Any thoughts on what I can do to try and get my 2 screens to work properly.

I'd try this. Check your cords as well, make sure they are not faulty. If those don't fix it, it is probably something to do with your laptop. If you have a different port you can use, such as mini-display, you should try those. I had a similar issue with a monitor in an HDMI port but had no problem with the same monitor using a mini-display port adapter in another port.

Points to consider:
1) power of the remote monitor. Consider changing the cable, confirming that it’s tight, especially if you see the power light on the monitor flicker
2) transmission cable has 3 points of failure- the connector at each end + what we will simply call “the cable itself.” This is probably a little more likely to be the point of failure. Unfortunately, the ports at each end could be the problem as well.
So I would first swap the transmission cable, use different ports if available, consider something like a cheap docking station if it’s supported, and then sort of see what happened from there.

Especially if you're dealing with something moveable like a laptop, you're flexing the connector inside the laptop every time you pull it an inch closer, move it back to get a better Teams picture, etc. I managed to destroy a mini-HDMI connector in a new laptop in less than six weeks. For cables, try Monoprice or Amazon basics.
This sounds borderline idiotic, but check the power savings settings on your ports in Device Manager. Windows can be too aggressive (although it seems to be more frequent with USB ports) in trying to put ports to sleep to conserve energy. If something like this happened, your system now thinks it has one display, not two, collapses all your windows onto the remaining monitor, and you have to drag stuff back to the secondary to make it awake.
Also, check for BIOS and chipset updates from Dell. While updates are few and far between for laptops vs. custom builds, try that after the cable swap.

HEAT: is it a "thin" laptop by chance? Those are have smaller power supplies and less space for air to move through. I bought a laptop cooler that sits under the laptop and the fans blow up from the bottom. Made a big difference in my temperatures. Under 20$ on amazon in Laptop Accessories.
random shut offs of a display are usually the laptop or video card in the laptop getting too hot. It has to use more power to extend the display.

It is thin but have it on a laptop stand to allow for air circulation

What type of port are you using to send signal from the laptop to the external monitor?
On the monitor, what type of port is the cable plugging into?
Check that your display doesn’t have DP 1.2 turned on.
That’s meant to be used with daisychaining monitors.
Go to the display settings on the monitor itself and look to see if that setting is enabled.
