Acabo de adquirir esta tv hoy mismo, en concreto la 55x8509c.
A ver si alguien puede ayudarme con un par de dudas:
1.- Tengo el pc conectado, en el panel de control de nvidia la reconoce como "SONY TV *02"; en 'administrador de dispositivos' en 'monitores' aparece como "Monitor PNP genérico" y en 'entradas y salidas de audio' como "SONY TV *02-4". El caso es que tanto en el 'panel de control de Nvidia' como en 'configuración de pantalla' de windows me da opción de resolución 4k (y funciona bien), pero señala al 1080p como 'nativa' o 'recomendada' en ambos. Es todo esto normal?
2.- No veo forma de poner el panel a 4K 60hz 4:4:4 10bit. He puesto HDMI 'mejorado' en 'entradas externas', y 'rango completo' en 'margen dinámico', además del modo juego. Las opciones que tengo son:
-"RGB" "Limitada/Completa" "8bpc"
-"YCbCr422" "Limitada" "8bpc/10bpc/12bpc"
-"YCbCr444" "Limitada" "8bpc"
-"YCbCr420" "Limitada" "8bpc/12bpc"
Qué pongo si el principal uso va a ser juegos de pc en 4k?
PD: Por si influye, tengo W10 y una MSI 1080. Muchas gracias!

Por cierto, respecto a cables HDMI, estoy viendo que hay 'standard', 'high speed' y 'premium high speed' (éste último no lo sabía). Es eso correcto? Lo digo porque estoy viendo que el mío es high speed (no pone nada de premium), concretamente pone "High speed HDMI cable with ethernet". Podría estar ahí el problema?

"These days all of the buzz is about 4K, and people associate the HDMI 2.0 specification with 4K, so it's important to point something out at the outset: not all 4K video is the same. HDMI has supported 4K resolutions since 1.4, but with limits. To keep the signal below the 3.4 Gbps/channel, 10.2 Gbps total limit, a 4K signal couldn't have a high framerate, or deep color. It is still the case as of this writing (November 2015) that most 4K sources which are being run in home theater systems are HDMI 1.3/1.4 "high speed" applications, not HDMI 2.0 extended-bandwidth applications, and for these flavors of 4K, the HDMI 1.3/1.4 "high speed" testing is adequate to represent the conditions of use.
But when HDMI 2.0-type 4K is being run -- currently mostly from computer video cards -- using an extended color gamut and/or high framerate (50 or 60 fps), the 1.3/1.4 testing does NOT represent the actual conditions of use for the cable. We are, at this writing, in "early days" for HDMI 2.0, but indications so far are that the honeymoon is largely over where cable run lengths are concerned. We've had a variety of customers write to us about their experiences when running full-bandwidth 2.0 video, and what they've been finding is that most "high speed cable" does not, at least when run near its longest certified limit, stand up to the task.
The Premium HDMI Cable program really has two elements, to address two different but related problems. First, there is the testing element: in addition to passing the conventional 1.3/1.4 Category 2 cable tests, which test the cable only out to 3.4 Gbps per channel (10.2 combined), the Premium testing program tests the cable's electrical characteristics all the way out to 6.0 Gbps/channel (18 Gbps combined) so that the certification test DOES represent the actual conditions of use of the cable. If the cable passes certification, it should ALWAYS function correctly when used to connect two HDMI 2.0-compliant devices."
EDITO: Pues parece que los tiros pueden ir por ahí. Efectivamente en muchas webs pone lo mismo. Otro ejemplo:
http://www.cepro.com/article/premium_hi ... he_market#
"The current HDMI specification supports enhanced features such as 4K/UltraHD@60Hz, bandwidth up to 18Gbps, BT.2020 colorimetry, 8/10/12/16 bit color, 4:4:4 sampling and 4:2:2, 4:2:0 subsampling and a long list of advanced capabilities including support for HDR. Products and content enabled with these features were the highlights of CES 2016, especially products featuring HDR such as 4K/UltraHD displays and UltraHD Blu-ray Players."
-Under the CTA definition for HDR-compatible displays, the displays need to support their HDR10 media profile video which uses the BT.2020 color space and a bit depth of 10 (among other things)
-HDR10 is supported by the Ultra HD Blu-ray Disc standard and is also supported by the influential UHD Alliance for their UltraHD Premium designation
-UltraHD Blu-ray also supports 4K, 60fps, and 4:2:0 (some even have an option for 4:4:4 output)
-BT.2020 colorimetry is defined by the ITU and includes support for 4K, 8K, 10/12 bit color, 4:4:4 sampling, and 4:2:2 and 4:2:0 chroma sub-sampling
18 Gbps speed is also being driven by 4K PC graphics cards and PC gaming which will utilize 60Hz and 4:4:4. The confusing part is knowing bandwidth requirements based on the actual implementations of various feature combinations and by product manufacturers. It’s definitely prudent to have some bandwidth headroom available. So you need to be prepared for today’s products as well as future-proof your installations and infrastructures.

Yo tengo 2 de marca RICABLE, estan en amazon y son 100x100 2.0
Luego me dices compañero
