Review on ViewSonic XG2705 27'' 144Hz Gaming Monitor - Frameless, FreeSync, Ergonomics, Anti-Glare by Joel Shepherd

You cannot use Gsyn or FreeSync with a 1ms response time. If you also enable the 1 ms response time, the image quality and brightness will be degraded by about 20%. When testing 144Hz with the UFO, there is significant ghosting even with a 1ms response time. I bought dll for 161, for such a price it is normal. But I would look for another one with better image quality and less ghosting.
