Sorry for the necro-posting, but I was just looking for some input on whether this idea of mine would work:
I haven't opened my monitor up yet to check, but would it be possible to replace the controller with this: https://www.alibaba.com/product-detail/eDP-LVDS-QHD-2K-PIP-PBP_60183246899.html?spm=a2700.77248126.96.36.199m6C19
to enable FreeSync support (and 144Hz, too)?
On the labeled diagram it says "dp output" which I'm assuming is for displayport, but LVDS should still get a feed from the displayport input, right?
Hoping this could work, would be a great upgrade for $30.
