Need help with this. Its troubling me for a month on which screen to buy. Stock screen is LP156WF6-SPP1. My research got me to this 2 panels. N156HHE-GA1 and B156HAN04.2. I read on some post that brightness control or g-sync doesn't seem to work properly on B156HAN04.2 hence I looked for some alternative. I'm not sure whether the N156HHE-GA1 would work. It has the same connector as the stock but doesn't state its Signal Pin Configuration. Does this mean it may not be compatible with my system?
