I'm currently trying to build my own display. I got the case from an old 27" monitor and I already know which panel I could order. The power supply is also not a problem. But I still can't find a good LCD controller manufacturer that sells/makes them as individual parts. The only thing I know is that Dell makes their own. I know that this is messy and I know that that this isn't the most practical way, but the Croatian market is just too bad. All of the prices are 2x higher than on eBay/Amazon and the shipping from USA is too expensive. The current specs I'm aiming at are 144Hz, 2560x1400px and 350 brightness and In the end it is aproximately 150$ cheaper (considering that the part I'm looking for costs around 140$).
