Walmart advertising HDR on non-HDR panels

[JaxonDouglas]

Walmart selling this TV https://www.walmart.ca/en/ip/sanyo-fw50c78f-50-4k-uhd-smart-tv-with-hdr-10/6000197993329

 

It is listed as having HDR on its spec sheet as well http://www.sanyo-av.com/us/product/product.php?id=726

 

The TV does not have a HDR panel but I guess it will process the HDR signal and that's how they get away with saying it has HDR? A family member bought this TV even though I told them to buy the TCL 4K 50" which was also cheaper with better software... 

 

I realize at this price point I shouldn't expect the HDR to be much to call home about but this is very misleading.

Listing HDR without calling out a specific HDR spec is very similar to how so many panels claim to be 120hz, though they really, really aren't. The TV is probably your standard cheap HDaRen't TV and your family member got good advice and went a different way instead, sounds like their own fault.

So it sounds like a problem with Sanyo, not Walmart.

It says it conforms to the HDR 10 spec, what makes you think it doesn't?

i asked that also because my samsung 7 series says its hdr 10 but it looks like dog crap...i asked @TheFlyingTraut about it and this is what he said
That tv doesn’t have a passive hdr panel. It’s not like their 8000 series or qleds. It essentially fakes the hdr. If you try streaming hdr from one of the apps on the tv it would probably look ok. But coming from an external source, it doesn’t have the capacity to even display hdr 100 or hdr 1000 content. 

so basicly the tv might say its hdr10 but it doesnt mean it will look good

[TheFlyingTraut]

Pretty much that. An HDR label on the box doesn't mean jack. That is why some retailers won't carry certain brands because the HDR standard isn't set on what can be on the box or not, so some retailers have more strict requirements for the manufacturers to sell their tv's with the HDR branding on the box. Once you read into the specs on the tv, you will realize it doesn't support full HDR10, just a capability to display HDR content.

 

Expecting a $500 tv to display full HDR10 is sort of unrealistic.

The problem is that the minimum requirement for HDR10 is mostly related to the signal of the video itself, not the actual capabilities of the panel. If you can process a 10-bit color signal, using the Rec.2020 color space and the SMPTE ST 2084 transfer function, you can claim your TV is HDR10 compliant even if the panel is hot TN garbage.

 

In fact, many early HDR TVs weren't even close to what the developers hoped for, such as really bright (e.g., 10,000 nit) displays and LCDs couldn't even come close to the desired contrast ratio.
