Here are some frequently asked questions on Second monitor lagging when playing games. If you have similar queries, I hope this will help you.
1. Does a second monitor hurt gaming performance?
Yes, while multiple monitors help increase productivity, they negatively impact gaming performance. Especially if you use low-end PCs, they cannot manage the resources required for both monitors and cause issues like flickering, lagging, and stuttering.
2. Why can't I use my second monitor while gaming?
If you are using a low-end PC or are facing issues like flickering or lagging on the second monitor, you should stop using the second monitor. If the PC cannot manage the resources to run both monitors smoothly, your gaming performance will be negatively impacted.
3. Why won't my second monitor go to 144Hz?
If the display settings on your computer are not set to 144Hz, the second monitor won't show it. Change the refresh rate to 144Hz or higher to change the refresh rate of the second monitor.
4. Why is my laptop screen lagging but not my monitor?
If the laptop screen is lagging, and not the monitor, you need to check the graphics card compatibility. If they are not compatible with higher refresh rates, the cards will find it hard to handle the rendering of images on the screen.
