Of course you do all that with every number/test, because biosrefl2.bat is flashing this modified BIOS and removing monitors is to force reinstalling a new monitor. It takes a few seconds to do the monitor reinstalling. Only after the first BIOS flash you do: monitor reinstall + clean install HD + monitor reinstall. Please pay attention to what I write, it is not necessary to come with this double questions after all the work I invested. I could have put you to do all the work in MMTool and command prompt, just provide the files, but I went a little further with batch, just to avoid this questions.

i just try with number 11......
can i ask something that makes me confused? i just want to avoid any mistakes.
1. in your instructions: "clean install HD" means that i need to remove the intel hd driver, restart the pc and install it again?
2. "switch between first and second panel type in Chipset" you mean switch between "tms150xg1-10tb" and "m185xtn01" in chipset bios menu?

thanks for your kindness to me.

The answer to your questions is: Yes and Yes!

But if you really want to go this way, despite the fact that I tried to do all the work and also provide (in my honest opinion, maybe I'm mistaken) accurate test conditions, then so be it. My work here is already done and I suppose a few minutes of my time is not that much of a loss.

Pre-condition: Inverter 200Hz

First test: run biosbck.bat, run #Any_update.bat and input the number 11, run biosrefl2.bat, reboot and remove all the monitor devices under Device Manager -> Monitor. Scan for new devices and Windows should add a new PnP monitor. Clean the video drivers like I already told you, remove the monitors once more, reboot and install 3517 drivers, reboot and test resolution.

The following tests: run biosbck.bat, run #Any_update.bat and input the number x (where x is from 12 to 22), run biosrefl2.bat, reboot and remove all the monitor devices under Device Manager -> Monitor. Scan for new devices and Windows should add a new PnP monitor. Reboot and test resolution.

Extra steps: with tests 11-18, switch between first and second panel type in Chipset Tab, test with both. With tests 11-16, 19, 21 select PWM Normal; the rest with PWM Inverted.

The first 6 tests (11-16) are important, the others you can skip if you want. If you do only these 6 tests, deduce from above: PWM Normal at 200Hz and switch between first and second panel type in Chipset Tab. The switching between panels must be done as a last step, when testing the resolution, with a simple reboot in between.

I think it is more or less the same as previous message, I really don't see what I could add.

@lordkag
i try it all from #11 to #22, and as your guess, no one works......
also i try with "m185xtn01" panel from bios, the effect little bit different than before for all of this test.
if in previous test they are blank, black, nothing....on this test the screen become white and blinking so many times until i shutdown the computer from power button.

anyway thanks a lot for your effort....
you are amazing :)

我也在研究这款主板，技嘉H77TN ,我从技嘉得到相关的修过之后的BIOS ，刷写之后可以支持正常的分辨率，包括 1024*768 ，需要的话给我发邮件 51336519@qq.com
