See all comments I currently use 4. I have a displaylink I bought from Amazon which has been great pluggable and the Surface Book dock. Adding multi monitors is easy in Windows Shouldn’t we be able to adjust that through scaling?

I use 2 P monitors and the Book 2’s 4K screen every day at work. It sounds like you’re encountering a settings or program specific issue. Used to cause me all sorts of problems with a second monitor on a Surface Pro 4, in the end I just bought a 4K monitor so the resolution was close to the Surface, now the issues are barely noticeable.

Not all applications suffer from this but if you use the ones that do, then it’s a real pain. I have three monitors one of them is actually a TV using with DisplayLink. Windows 10 made it bit easy to use multiple screens! I also use DispayFusion software that allows easily move the windows one to another monitor.

Also it has ton of other settings especially different wallpapers on each monitor. Every now and then all the apps switch monitors but the stretched wallpaper remains correct. The Xubuntu box on the third KVM channel stays stable. Otherwise setting the monitors up was a breeze. It used to reboot sporadically overnight until probably about two months ago.

It’s a lot more stable now. A really well designed app I use on my multi-monitor setup is DisplayFusion. I like being able to fill both monitors with one single image.

The only problem I have started cropping up a few weeks ago. Whenever the system goes to sleep, the Dells don’t wake up from mouse or keyboard action, only the SP4.

Any chance the Anniversary Update affected this? Make sure the cable supports the correct version of the display standard.

USB-C and Thunderbolt monitors are even more confusing because the cables are physically interchangeable but not cross-compatible. DVI, meanwhile, has multiple versions , and it’s possible to plug an incompatible DVI cable into a computer or monitor. Check the cable’s documentation on the manufacturer’s website to find the latest display connection version supported by the cable. If the cable doesn’t support your display, replace it with a cable that does. Additionally, check the appearance of the connectors on the cable, computer, and monitors to ensure they’re compatible.

Remove any switches or converters from the signal chain. If possible, remove or replace dongles and switches temporarily. If the simpler connection works, the removed device is to blame. Try a different display interface. This can accomplish a few things. If the current interface can’t drive all the pixels in the second monitor, switching to a different interface can fix that problem.

Unless you must use a VGA connection for legacy compatibility, avoid it; it cannot properly drive modern displays. Just because you can plug a cable into a port doesn’t mean you’ll have full compatibility. Update the computer’s display drivers. If you have a third-party discrete graphics card, update the drivers from the manufacturer. If you plug the monitor into the motherboard’s display connectors, visit the motherboard or computer manufacturer’s website to check for updated drivers for those features.

Lower the image quality. If the monitor suffers from a poor frame rate, choppiness, or corrupted video or game content, reducing the signal’s complexity can help. For games, try the lowest-quality settings first, then gradually improve the quality until the issue reappears. For video content, try a lower resolution or a less demanding frame rate. Check the power connections. If the monitor doesn’t turn on , try different power connectors or wall outlets. Test wall outlets with other devices before plugging in the monitor to ensure those devices work properly.

Check the monitor’s input settings. If the monitor has multiple input interfaces, make sure you have the correct one selected in the monitor’s on-screen menu. Most monitors have an auto-detect feature that automatically switches to the connector receiving the signal.

When that doesn’t work, set the display connector manually. Expand Display Adapters , double-click on the entry of display adapters. Click the tab Driver , click Uninstall. Step 2 : Visit the Manufactures website and download the latest driver.

Note : Before uninstalling the driver, please make sure that you have downloaded the latest Display Adapters from the manufacturer website. I have been able to use an extended screen for a year since “up-grading” to Windows Recent updates have left me unable to extend the screen.
