How to change resolution m.nt68676.2?

Question

Do it yourself

The old laptop asus x61sl (aka f50) honestly served for 4 years, got burned out by the power circuit, lay for several months in services and lay on the shelf as a useless piece of plastic. But one day an idea came up - I turn off the screen from it (there is a Samsung matrix LTN154X3 - L03), I screw it to the table, I connect it to the raspberry pi and I will have almost a desktop on the table from almost nothing.
And I ordered the m.nt68676.2 controller, it came to work, but instead of 1366x768, which this matrix displays, it displays 1440x900, it looks like a poorly readable font and a wide black bar on the right.
If I understood everything correctly, I need to reflash it for the required resolution.
Well, actually: if I understand everything correctly - please give me a link to the corresponding firmware, if I'm wrong somewhere - point me to it.
Thank you for your attention

Did you poke around in the controller menu? Maybe there you can set permission?
Or maybe you can force permission on rapsberry?
I don’t know why the seller didn’t ask you, but when I bought it, they asked me which display I would connect to the controller so that they would flash me a suitable version. You can try to write to the seller about your problem, maybe they will send the firmware.
At the very least, buy a controller where you can set the resolution with jumpers.
