Decided to compare my 55" GX with my Acer X27 (384 zones, 1000+ nits). Purpose was mainly to compare brightness and "pop" so I put both into the most vibrant mode (again, not to compare best PQ). Source was YouTube videos running at [email protected]
with HDR. To my great surprise, the GX was actually able to make the perceived brightness and pop even in a bright sunlit room.And this was not cherry picked clips either to favor OLED (at least not intentionaly), included for instance the Sniper trailer which is almost entirely daytime.
While the merits of OLED regarding black levels etc. are probably well known by now, I did not expect this. There were differences of course, but overall I would say it was a draw, and if you factor in stuff like perfect blacks etc. it was a clear victory for the GX.
Now, I don't claim to be an expert so this is my personal opinions on the matter, nothing more, nothing less. But perhaps interesting to others as well.
(The Acer was running Display Port but both fed from the same GPU, a 1080ti, of course confrimed that both were in fact running HDR).
