Resolution solution for Warcraft in win7

My computer is a wide screen. After switching from XP to Windows 7, I played Warcraft. There were always two black bands on both sides of the screen, setting the game resolution to 1024*768*32, no matter whether it is used. although my computer resolution is 1366*768, but in XP, when the game resolution is 1024*768*32, there is still no black bars on both sides of the full screen.
After searching for the Internet, I found that someone on the Sina Blog has provided a solution:
Create a registry import file war3revolution. Reg and write the following content to it:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER \ Software \ Blizzard Entertainment]
[HKEY_CURRENT_USER \ Software \ Blizzard Entertainment \ Warcraft III]
[HKEY_CURRENT_USER \ Software \ Blizzard Entertainment \ Warcraft III \ video]
"Reswidth" = DWORD: 00000556
"Resheight" = DWORD: 00000320
"Colordepth" = DWORD: 00000020

This is a 1024*768*32 Resolution solution.
Reswidth indicates the length, resheight indicates the height, and colordepth indicates the color depth.

Deword values corresponding to some common values:
800 00000320
600 00000258
768 00000300
1280 00000500

How do I calculate the DWORD Value of a resolution value that is not commonly used?
Open Windows Calculator (win key + R, enter Calc to open), select

For example, if the screen resolution is 1366, select Dec (10 hexadecimal) and DWORD, enter 1366 in the Value box, and then select the DEC block as hex (16 hexadecimal ),

The conversion result is as follows:

When using the registry, you need to fill in the DWORD Value to 8 bits. Therefore, add 5 bits to the first part of 556. The result is the DWORD Value of 1366.

My configurations are as follows:
