Help me find a specific cable

[wetblowdryer]

Hi guys,

 

I bought a 4K HDR tv and I tried plugging it into my 1080 ti, however, I cannot enable HDR. I can however run it at 4K60fps, just not HDR. I don’t think it’s a driver or system issue as I can run HDR on lower resolutions. I have this cable btw. I know it can run 4k60fps HDR on DisplayPort, but my tv doesn’t have display port. Do I just need a display port to hdmi 2.1 adapter or am I missing something? If you know about one, please link it as it’s been difficult for me to find one. Thanks.

What kind of TV? Did you enable 4K Enhanced mode? How are you enabling HDR on the PC? Have you tried a different cable?

 

You don't need HDMI 2.1 for 4K 60fps HDR. You should be looking for Certified Premium HDMI cable.

I have UN43TU7000FXZA. I'm trying through NVidia control panel. I get the following options and can't change them in 4k.

 

 

When I downscale the display to 1080p, I get these options

 

 

I go into Window's HDR section and I get this, not matter what the options. Will that cable help?

Usually a TV will have only one port that can handle the HDR or 4K signals. Make sure you're plugged into the right HDMI port on your TV.

nope, no effect. And there are only two ports, unfortunately.

I’ll buy the chord dilpickle told me to, because I need another HDMI cable regardless. Can never have too many of those.

Did you enable HDMI UHD Color on the Samsung

I can’t find any options for HDR. I only see one setting called HGiG which apparently sets picture quality according to brightness of game content with HDR.

Try this

I swear that option is not there. The only thing I can think of is messing with the firmware or that it's the wire and Samsung's TVs are so advanced that HDR just happens automatically if you can enable it in OS with no need to flip through menus. The new cable comes Monday so I'll let you dudes know.

Ok, new cables arrived and no changes. I tried with my 4K monitor to enable HDR and it worked with the HDMI cables, but not for the TV. To show I’m not crazy (or maybe to confirm), here are the options in my tv’s menu

 

under picture settings:

picture mode

picture size setting

brightness

contrast

sharpness

color

tint

apply picture settings (to all sources)

picture clarity setting

contrast enhancer

film mode

color tone

white balance 

gamma

bt.1886

shadow detail

RGB only mode

color space settings

reset picture

 

under External device manager:

Anynet+ (HDMI-CEC)

game mode

input signal plus

hdmi black levels

input device manager 

device connect manager

HGiG

 

Im running Windows 10 20h1. I still have to use chroma sub sampling 4:2:0 according to NVidia.

Ok, I have FINALLY found the solution. You obviously need a a good HDMI cable, which I have two now . You go to general settings, external device manager, click on Input Signal Plus, select the HDMI input you want, ensure it is on full dynamic range in Nvidia control panel, and enable HDR in Windows. These options are NOT SELECTED BY DEFAULT and its label is not self-explanatory.
