the performance of your computer.

Frequently Asked Questions

How come my computer slower when I have two screens?

The majority of desktop computers are designed to operate with just one display. They can be set up to detect the second monitor and reduce the processing power to fit the single display. However, if you’re using two monitors then you’ll need to manually adjust the settings to permit the second monitor to be running at its full resolution.

Can dual monitors cause lag?

Dual monitors can create delays, particularly if they’re both set to similar resolutions. The majority of computers have one monitor set to 2048 x 1080 pixels while the other one is set at 1280 1024 pixels. This means that both monitors will be displayed with a resolution of approximately 30 FPS (frames every second).
If each screen is set to similar resolutions each screen will show 60 frames per second. This is less than what you need for smooth gaming or watching content. This is the reason why users prefer to use one monitor to view content while the other is for game.


We’ve covered the most frequent causes and the best ways to solve dual monitor lags within Windows. If you’re having this issue, do not panic as the solutions are easy. The first step is to need to clear your RAM and graphics card. Then, you need to install the most recent graphic card as well as RAM into your laptop.
