Does it need to be 1440p? Acer makes a fast/decent 1080p VA 35" curved panel, I've seen them set up in the shop, very nice for a 1080p, and it has Gsync. They make a 1440p version, but it's IPS and about 40% higher in price.
AOC has some decent 34/35" too. I don't know much about using TVs for primary gaming use, there has to be some options in that 34-ish size that'd work for you too, I know there are a few guys here up on what TVs are best for this.
