Is it ok to change degrade the laptop screen resolution from FHD to HD?

Added (1). i have lenovo y510p SLI my screen resolution was 1080p and i wanna degrade it HD for better frame rate. Can i buy a screen of 1366*768 on the online site for lenovo y510p and replace my self or there will be a change in the pins for lenovo y510p's 1080p laptop screen and and the screen i buy from online site. Or there will any other issues that
like not recognizable or something because it came default by 1080p screen.

You don't need to replace the screen with a lower quality screen.
You can select 1366*768 in Windows, and your current screen will work at HD instead of FHD.
Just right click on an empty place on your Windows Desktop, and click "Screen Resolution", choose 1366*768 in the list of available resolutions.
If you see black bars, use the graphics system to correct. In case you're using Intel HD graphics - the attached image will show how to do it, SELECT "SCALE FULL SCREEN".
If you're using some other graphics card, check the settings of the graphics card and look for a similar option. Is it ok to change degrade the laptop screen resolution from FHD to HD
