lsp files define interface or HUD elements.

For instance cp_life_360.lsp define the HUD (the lifebar) for both players. Each part of the HUD has a short name, like : "1p_item04", shortly after that is a C length variable which defines the scale, which is normally:
"00 00 80 3F 00 00 80 3F 00 00 80 3F"

Replacing the scale with all zeroes makes it invisible.

Nearby there's also a string which references which texture that element should use.

If you search for "00 04 00 00 40 02" those are the hex numbers which defines "1024x576". (240(hex) = 576 - 400(hex) = 1024)
And "00 05 00 00 D0 02" is "1280x720" (from the benchmark.lsp) (2D0(hex) = 720 - 500(hex) = 1280)
"80 07 00 00 38 04" is 1920x1080 (438(hex) = 1080 - 780(hex) = 1920)

The resolution of an entry is defined just before the name of the texture filename.
