Auto Change desktop resolution according to game resolution

[Storm488]

On my old machine(a really low end one) whenever I launch a game change the resolution in the game, the desktop resolution would automatically change to that so that the game fits the entire screen.

Now I bought a new laptop but in this it does not change the resolution so the game runs like a square with black sides.

Basically I want my laptop to also have a similar feature so as to fit the game to full screen and return to default resolution on closing it.

Suggest a solution please.

You can't add functionality that doesn't exist. Just run your game in a supported resolution like 720p. If your game doesn't support that type of resolution, run it windowed

My laptop is 1080p, but I cannot run every game in that resolution due to frame rate loss. If I lower the resolution of the game, it would appear in a box once again.

Are you sure there is no such feature as to strech the game to fullscreen?
And by that I mean changing desktop resolution to the same as of game resolution and restore it back on closing.
It can be done manually I'm sure.

No, if your monitor doesn't support the resolution, it won't happen.

If the sides are just left/right, that means you're picking a 4:3 resolution for a 16:9 display. Just use 720p resolution like I said before
