Lagging on my external monitor when gaming.

Hi Brandon,

OK, on your laptop, instead of using Windows 10 to mirror your screen to your external monitor, cancel this and look for a key on your keyboard (usually an F Key) with a symbol on it that will more than likely look like one of the symbols in the picture below.

Pressing this button will instantly turn your laptop screen off and send your display to your external monitor (that's what the button represents). This is how I use my own external display on my laptop. Pressing the button a second time will reverse the process and turn your external monitor off and send the display back to your laptop screen. This process absolutely ensures that there is no secondary display being used by your GPU, and therefore dragging your FPS down on your external monitor.

Depending on whether the F Keys are dominant or the symbols are dominant on those F keys, you may need to press the Fn Key + the F Key with the External Display symbol on it to access this feature.

99% of laptops have this key.

This should make sure you have a lag-free experience hopefully. I was hoping that closing the lid would be enough, but sometimes you need to use the Ext Key to make sure only one display is being utilised.

Please do let me know how you get on.

Kindest regards,

Neil

Hi Brandon,

When you are using the external monitor, you need to close the lid of your laptop screen as this will also cause your monitor to lag.

Please try this and get back to me.

Hi Brandon, my name is Neil, and I'm a Windows 10 user like you.

I'll be happy to help you with your question.

Sorry you're experiencing lag with your external monitor.

Normally, updating your monitor and GPU drivers will fix this issue.

To update your GPU driver, please make sure you get this driver from your laptop manufacturer (Asus). The reason for this is that laptop GPU's have slight modifications made to the driver architecture to get the best performance out of the GPU and the custom system.

These drivers can only be found on Asus. If you download the driver direct from the GPU manufacturer (NVIDIA or AMD), these drivers are missing these small modifications and can cause issues with your system.

Also, don't worry if a GPU driver appears to be old. This is normal, as laptop manufacturers don't release a lot of GPU drivers. They only release ones that work and are fully supported, so these tend to be older in contrast to a GPU manufacturer's drivers release schedule.

To check for any updates for your monitor, please do the following:

Right click your Windows Start button.

Click on "Device Manager"

In Device Manager, expand the section ">Monitors" and locate your monitor.

Right click your monitor and then click on "Update driver".

Click on "Search automatically for drivers".

See if it finds any updated drivers for your monitor.

If none are found, click on "Search for updated drivers on Windows Update" and see if you can find any drivers there.

Please do let me know how you get on.

Kindest regards,

Neil

2. The Display driver is so important here that merely updating it is sometimes not enough. So let's try everything possible to get it working correctly:

First make sure you have updated the Display driver from the PC or Display adapter maker's Support Downloads web page for your exact model number, HP Serial Number or Dell Service Tag - from the sticker on the PC.

If necessary first remove the old driver using DDU https://www.wagnardsoft.com/content/ddu-guide-t... (not necessary with Microsoft Basic driver which is a placeholder if nothing else is available) and/or installing in Safe Mode with Networking (so you have internet), or Safe Mode, accessed by one of these methods: https://www.digitalcitizen.life/4-ways-boot-saf...

While there check also for newer chipset, BIOS/UEFI firmware (very important), network, sound, USB3 and other drivers, comparing to the ones presently installed in Device Manager reached by right clicking the Start Menu.

If this doesn't give you the latest or ideal driver for what you need, compare it to the driver offered by the Intel driver update Utility here: http://www.intel.com/content/www/us/en/support/...

or the Nvidia Update utility here: http://www.nvidia.com/Download/Scan.aspx?lang=e...

or the AMD autodect utility here: http://support.amd.com/us/gpudownload/windows/P...

For Display issues one fix that is working is to Roll back or Uninstall the Driver on the Display Device > Driver tab, restart PC to reinstall driver.

You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick.

Then you will know you've tried everything in addition to Windows Update drivers.

Adjust the screen resolution until it fits and looks best at Settings > System > Display.

Check for a monitor driver by expediting Windows Updates (including Optional Updates) in Settings > Update & Security > Windows Update > Check for Updates to install all Updates until no more are offered.

Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.

Hi Brandon,

I'm very sorry, but I'm out of ideas and I cannot think of another solution.

This is an open forum and maybe someone else will have a solution for you.

Again, I apologise for not being able to solve your problem.

Thank you for your time.

Kindest regards,

Neil
