Update:
the 55" LG CX arrived 3 days ago,everything setup according to HDTVTest and Rtings.
I was also able to sell my Samsung Series 7 QLED 55Q7F locally for £500.(it cost me £1200 January 2018) so the CX being £980, I payed £480 to upgrade from 2018 Q7F QLED to 2020 CX OLED.
but was it worth it?
CX Pros : 1-SLIGHTLY better picture quality overal,a little better blacks and contrast
2-4x HDMI 2.1 ports (so 4k 120Hz for my Gaming PC and PS5)
CX Cons : 1-immediately noticeable black crush in certain movies/series (in dark scenes) ,so all the details are lost and person wearing black becomes part of the black background lol
I can't believe this isn't being mentioned more by likes of HDTVtest,Rtings etc! I can live with it I think ,as it's not happening in every movie,but it's really a problem.
2-I do not like the web OS vs Samsung's Tyzen OS,it's slow and just doesn't feel as snappy and straightforward vs Tyzen
3-I don't like the 2 tone silver ,short design of the stand, my Samsung Q7,and Q90T have much sleeker,more modern stand design.overall build quality of Samsung was noticeably nicer
4-I don't like the bulky remote and motion controls, Samsung had 2 remotes and the metal minimalistic smart control was really nice to hold and use.this looks and feels backwards in comparisson.
5-and of course the constant worry about burn in,but that's something I already accepted ,there are things I can't simply risk on this TV anymore,for example I used leave Spotify running for hours on my QLED,connected to my soundbar system, this is obviously a big no no on OLED.
overall,I'm ok with it but frankly it's a little disappointing.the HDMi 2.1 4k 120Hz are really important for me but to be honest,the picture quality difference between this and the Q7F isn't worth £100 extra let alone £480 in my case.
I think it's amazing how Samsung was able to achieve such high contrast and deep blacks with minimal,really unnoticeable blooming and light bleed on a edge lit TV.that's what i understand.
the 6/ 60 seties QLEDs are very inferior but mine and the Q9/Q90 range are without anydoubt potential alternatives to LG OLED.
