Just pulled the trigger yesterday, and here are my reasons:
(1.) I'm a tech geek and I couldn't resist the allure of HDMI 2.1. I'm going to hold on to this TV for a loooong time. When I buy a good TV, it's going to last and as a result, in 3 years, HDMI devices will all be upgraded to 2.1 and I want to be able to take advantage of the additional bandwidth for gaming, which leads me to...
(2.) Q90R is the best gaming rig today but without HDMI 2.1, in 3 years it may be hamstrung. Again, both are expensive TVs and since I plan to hold on to these TVs past 5 years as I upgrade to PS 5 or Xbox Anaconda in 2021, they will both be running HDMI 2.1 but the Q90R will not. Oooops.
(3.) I don't need the extra brightness or glare reduction in my dedicated HT area. I'm a serious movie watcher, and as this is my "home theater" rig, I would like to get accurate cinematic details that ONLY an OLED delivers (and I would have bought the Sony AG9 if I not for its lackluster gaming support, ironically enough). After perusing way too many reviews of the Q90R, the number one complaint (see
) is that Samsung blasts the brightness settings and color saturation for maximum appeal to consumers/gamers shopping in brightly lit showrooms. Consequently, out of the box, movie watchers need to re-calibrate it, and even then it's impossible to get color accuracy - gamers don't care but movie watchers do. Also, I have a light controlled HT area, so the super duper panel brightness is wasted - I prefer the C9's more accurate HDR and color gamut. If this was going into my brightly lit kids play area, then definitely I would have gone with the Q90R.
(4.) What pushed my decision (but not the primary reason) to stop my research and bite the bullet yesterday is the Memorial Day promotion by LG: 15% off the 77" and 55" (Costco only but Best Buy was willing to match)
Hope this helps!
