does anybody use sports mode - picture seems too high contrast and colour for my liking but does it make a difference to watching Rugby .... or football i suppose
I never use 'Sports' mode! I hate the overall saturation the picture gives and prefer the more 'natural' look myself.
I fail to see any benefit using Game Mode on this TV, the lag difference is barely noticeable, HDR doesn't seem to affect anything. I use movie mode, the image on Horizon 3 looks tons better, Game Mode will always crush your image, with other TV's game mode is a must, on the KS8000 you don't need it at all....there, I said something good about the KS8000, jeez, I feel dirty.
I certainly notice the difference in Lag but then I have become accustomed to using 'Game' mode over the years and find anything above 30-40ms feels a bit unresponsive. If I were to use Movie mode for example, the Lag seems to take a lifetime but its still only a bit more than a 10th of a second in reality. A tenth of a second is still an incredibly small time in reality - Games like CoD which are renown for quick kill times - still take around 3-4 tenths of a second to kill someone.
Lag in game mode though is around 2 hundredths (0.02s) of a second and around a tenth of a second quicker than movie mode (around 0.12s). On games like CoD, that difference is the difference between getting the first shot in or being shot first.
Input Lag is essentially the delay between the TV receiving an image and that image being shown on screen. It may seem like there is a delay in pressing a button on a controller and seeing that action on screen. In a fast paced Multi-player, Lag can be important. An enemy could come round a corner and start shooting you before you actually see them on your screen. At 60fps, a low input lag is essentially only 1 frame behind but in Movie mode, this can be as high as 8/9 frames behind.
Game Mode certainly doesn't crush the image at all. You have just got used to seeing games etc with all the processing which basically overlays a filter over the image. All 'Game mode' does is turn off a lot of the 'processing' and motion options that delay the time it takes for the image to appear on screen. When watching the TV, it doesn't matter if the TV spends a tenth of a second processing the image before displaying it. It basically takes the supplied image and then applies various electronic processes before displaying that on the screen, the more processes, the longer it takes. Think of it like running a set of 'macros' on a photograph in photoshop. The less macro steps, the quicker it finishes.
The image in Game Mode is at it's most 'raw' in essence. It doesn't crush the info but its also not applying as many 'filters' or image processing. I don't know what console you use but have you set up your console and TV 'Game' mode correctly? Are you running the console through an Amp or directly into the OCB?
I see you have an XB1s as I do and that can be set to 10bit colour (to match the 10bit Panel) and I have mine connected directly to HDMI3. The PS4 Pro isn't out yet but when I get mine, I will connect that directly to HDMI2. I also have the colour set to Native on my TV.
