I found a way to change active pixels. It looks like DTD Calculator is not only showing my internal display, it shows a combination of all displays.

However, using it crashes my drivers and make windows bluescreen with VIDEO_TDR_FAILURE error.
Fortunately, I fixed that too

EnTechTaiwan also have a utility named MonInfo. Here is what I found on here:
Timing characteristics:
Horizontal scan range.... 30-83kHz
Vertical scan range...... 56-76Hz
Video bandwidth.......... 140MHz
Native/preferred timing.. 1280x1024p at 60Hz (5:4)
Modeline............... "1280x1024" 108,000 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync
If I don't pass the 140MHz mark. GPU drivers don't crash.
However, now the monitor is acting weird.
1. Both MonInfo, Windows and Monitor's documentation says this monitor can run between 56-76Hz. And I can't manage to run it on 56Hz. If I use a refresh rate below 60, it'll go into sleep mode.
2. Another problem is vertical resolution. It don't go beyond 1024px. If I try a resolution a few px larger than 1024px (example 1050px) it crops from bottom. Using a noticably large resolution (example 1280px) it'll go into sleep mode, just like the low refresh rate.
