MSI GTX 970 + LG UHD TV @ 60Hz 4:4:4 : Finally It Works!




MSI GTX 970 + LG UHD TV @ 60Hz 4:4:4 : Finally It Works!

The first post of 2015 starts with a good news: I finally managed to get my UHD TV (LG 49UB850V) to work @ 60Hz with a chroma subsampling of 4:4:4 (more on GTX 970 + 4K TV HERE). This is confirmed with the THE QUICK BROWN FOX chroma torture test available in this post.

I updated the LG UHD TV with the latest firmware (04.36.32) and the most important I think, is the update of the VGA BIOS of the MSI GeForce GTX 970: 84.04.2f.00.50. I also installed the latest R347.09 (Windows 8.1 64-bit).

As I said in this review, the new VGA BIOS improved several things like GPU throttling or in our current case, the 4:4:4 chroma subsampling with a 4K resolution @ 60Hz.

The GTX 970 is plugged to the LG TV using the HDMI 2.0 output port (GTX 970) and the HDMI 3 (10-bit) input port of the TV. I also set the HDMI UHD Deep Colour to ON (on the LG TV).

So today I can confirm that the team GTX 900 series + LG 49UB850V can work at 4K @ 60Hk 4:4:4.

And better late than never, happy new year 2k15 to all Geeks3D’s readers!

THE QUICK BROWN FOX chroma torture: if you can read the red and blue lines, that means the chroma is 4:4:4

    Do you know where to buy a Mini DisplayPort to HDMI 2.0 adapter to achieve 4k@60Hz on LG 40UB8000T HDMI HDCP2.2 port. Thanks

    That’s good news.

    Is it true though that UHD TVs are not good for games?

    I heard something about bad motion resolution, which result in a lot of blur when motion is fast.

    I have troubles doing what you did m8 and i bust my @@ 2 days now…

    I have the LG 55UB950v with bigger firmware than you but in no way my 970 letting me to choose 4k 60p anywhere in settings…
    The only thing i didnt do is to upgrade my Gigabyte Gaming G1 970.. because im afraid to do that… never done that before.. my current bios in the card is 84.04.2F.00.81 which seems bigger than the one you put…
    Also i use the Original Cable supplied with the TV and finally i am not able to enable the UHD Deep Color because i get that annoying popup saying there is no connected device that supports this, offcourse all this in HDMI-3 of the TV.

    Any thoughts on this?
    thx in advance

I´am using on my PC graphic card from Gigabyte GTX 950 Windforce and my question is. Will this tested LG TV work with my graphics card (GTX 950) connected through HDMI 2.0 cable without problems? Or could You recommending me, what to be more careful when choosing 4K UHD TV as a PC monitor, or do You have some overview other TV´s, which works fine? Thank You very much for Your posts.
