201812: TV in living room was destroyed with a blunt instrument, need to buy new fast.
202004: Wife want a new TV in the bedroom (the old have a partly broken screen).
202009: Kids gaming TV is broken, buying TVs seems to never stop.
Here are my considerations :
- Size :
- 55" : B-7K cheaper than 65"
- 65" : good feeling rush of success
- Brand :
- Samsung : we already have and in my age I like familiarity
- OS : Tizen - non-cluttered and less capable Bixby.
- Sony : for the kids more fun to see that different TV's have different OS
- OS : Android TV - more cluttered but more easily accessible functionality and more capable Google Assistent (I don't think all Sony's Android TV's have Google Assistent though).
- LG :
- OS : webOS and Google Assistant.
- Display :
- 4K LED : cheap and I think good enough (I don't have experience with high end)
- OLED : LG & Sony high end. (All OLED is produced by LG)
- QLED : Samsung high end.
- Viewing angles : this bedroom TV will serve not only our bed but also a running machine to the left and a work station to the right and while we can swivel the TV on the table stand - it would still be good to have better viewing angle - it seems Samsung have developed something called Ultra Viewing Angle.
- Last years models : don't seem to be available and and they are also for the Samsung 7100 model a bit slower.
Models of interest :
- 55ru7400 : 202004 we ended up buying this.
- New interest in 202008 :
- 55TU7000 (B12K)
- UA55TU8000 (B12.3K)
- UA55TU8100KXXT (B14K) 202008 we ended up buying this.
- UA55TU8500KXXT (B17K)
- 55RU7200 (B11.3K)
- Crystal 4K UHD, which like RU8xxx supports original 4K pictures but also are able to enhance non-4K to nearly 4K.
- Game Enhancer : making game scenes more smooth, however the RU8xxx have a better motion technology. However the TU8 game motion plus is better than TU7 game motion.
- Color technology is again better in RU8xxx
- TU8 have better remote control than TU7
- TU8000 vs TU8500 : TU85 have Dual LED wiich giver more color space.
Appendix : TV models naming conventions
- Samsung model naming convention : UN65RU7100FXZA
- U : I think denotes the screen type eg. U for LED
- N: region for which the TV is made.
- 65 : size in inches.
- R : year of development (N : 2018, R: 2019, T: 2020)
- U : resolution (S : SUHD, U: UHD, No: Full HD)
- 7 : series.
- 1 : model in series.
- 00 : design like stand, shape, body color.
- F : tuner type.
- X : ?
- ZA : country code there the TV is assembled.
- LG model naming convention : 65B9xyz
- 65 : size
- B : ?
- 9 : year of development (8 : 2018, 9: 2019)
- x : region code
- y : tuner type
- z : design type
Appendix : TV Terminology
- FHD : Full HD 1920x1080 pixels
- 4K : 3840x2160 pixels
- UHD : Ultra High Definition - I think it just means anything above FHD
- LED: Light-Emitting Diode - can display deeper dark than LCD and possible also brighter and have a thinner screen.
- OLED : Organic LED : high end screens.
- QLED : Samsung high end screens.
- SDR : Standard Dynamic Range - Dynamic Range is also known as Luminosity : the amount of information between the darkest and brightest part of an image. SDR have less detail information than HDR an apparently easily visible difference.
- HDR : High Dynamic Range - while SDR typically have 6 stops between darkest and brightest, HDR have 17.6 or nearly 3 times as many and therefore less pixels will be merged into the same brightness and the picture therefore more detailed. HDR must be served over HDMI2.0 or DisplayPort.
- HDR10 : a standard version of HDR (HDR Dolby Vision is another and much better HDR version but is expensive and too good for TV's today). Samsung boast some HDR10+ technology, which should be between HDR10 and HDR Dolby Vision.
- Panel : (Good comparison @Techspot)
- IPS : In-Plane Switching : Samsung have a variant called PLS : best for Viewing Angles. Contrast nearly as bad as TN.
- VA : Vertical Alignment : Samsung have a variant called SVA : better Viewing Angle than TN but less good than IPS. Best contract by far.
- TN : Twisted Nematic : oldest with bad Viewing Angle. Worst contrast. Best refresh rates.
