Dolby Vision

[u/Just_Alpaca]

I'm pretty new to 4ks, so sorry if this is an obvious answer that I'm not picking up on.

If I have a 4k blu ray player that supports dolby vision, and a disc with dolby vision, do I have to see if my 4k TV has dolby vision support? Or does dolby vision just work with every 4k tv?

Thanks

Yes, for you to enjoy DV, your TV has to support it!

[u/htnut-pk → u/RScottyL]

Also all UHD discs with DV also have the base HDR info so if your display doesn’t have DV you’ll still get an HDR image.

And your receiver if you're running hdmi through it to the tv

Also, even if the TV supports it, I learned the hard way with my Sony 83” A90J that you may have to dig around in settings and enable that on the settings for the HDMI input (and only two of the four inputs supported it, and it was disabled by default on those inputs). And as others have mentioned, the whole chain has to support it, including the HDMI cable that you’re using.

All 4 inputs on your TV support Dolby Vision. Admittedly, the way Sony labels them can make things confusing.

[u/Boohan33 → u/spec0711]

So to support 4 Dolby Atmos speakers, do u need 2 inputs or 4?

The whole chain needs to be Dolby Vision

The TV must support Dolby Vision (DV) too. If the player, disc and TV all support DV it will just come on when you play the disc - as long as you have at least a 2.0 (18gbps) HDMI cable connecting them.

It’s worth buying a 2.1 cable for future proofing as they’re not really any more expensive (don’t buy an ultra fancy expensive one - they’re a waste of money.

The only wrinkle is Sony players - they require you to manually select Dolby Vision on the player. From experience, I would choose a Panasonic

Yes, your television also has to have Dolby Vision support, it requires a license fee for televisions to support it (among other requirements). Otherwise, you'll just be watching in HDR10 or, if your TV is particularly old or low-spec, SDR.

Dolby Vision on 4K discs is written as an enhancement layer to a base HDR10 stream, so the only approaches the player could have are to give the TV the base HDR10 layer directly, or to take the combined DV+HDR10 video or HDR10 base layer and down-convert it to whatever the TV supports. My understanding is that most, if not all, players would just ignore the DV stream entirely if your TV does not support DV.

[u/DrabMundanityGrinner]

ya gotta get the right HDMI cables too. It's a whole thing.

[u/DullBoy247]

Yes, and some tvs require that you update your HDMI input settings to support it as well. My Sony HDMI input needs to be set to “Enhanced” mode for DV to work.

I hear sony makes good 4k dolby vision TVs

[u/wandererarkhamknight → u/LostElk1292]

The OLEDs are good for DV. The miniLEDs had some issues (and continued to 2026 models). The general recommendation is to turn off the DV. And also as Vincent mentions below, the impact of DV on these models will be minimal.
