LCD SEC3255=1600x1200 shows only 1400x1050

I got Windows 7 running on my old Inspiron 8200 with GeForce4 440 Go (0x0174), but I had the 1400x1050 problem. I tried the fix on the first post but it did not fix the problem. Then I discovered that there is a mistake (typo?) in the fix. Here is the corrected version.

HKR,,OverrideEdidFlags0,%REG_BINARY%,

3A,C4,00,03,00,00,FF,FF,04,00,00,00,00,7F,00,ff,

ff,ff,ff,ff,ff,00,4c,a3,55,32,00,00,00,00,00,0d,

01,03,80,1e,17,78,0a,ad,75,96,57,52,89,27,23,50,

54,00,00,00,01,01,01,01,01,01,01,01,01,01,01,01,

01,01,01,01,48,3f,40,30,62,b0,32,40,40,80,6e,11,

30,e4,10,00,00,19,00,00,00,0f,00,00,00,00,00,00,

00,00,00,19,af,02,32,00,00,00,00,fe,00,4d,31,36,

33,35,02,31,35,30,55,32,0a,20,00,00,00,fe,00,e6,

d6,c0,a9,8a,67,43,00,02,0a,20,20,20,00,38

The above version works on Windows 7.

Does anyone know way this string has 14 more bytes than a normal EDID?
