I’ve just sent an email now even though I think it would be more useful for everybody we could figure it out in this forum. I’m sure more people will benefit from this.

This is my email:

Hi,

I’m trying to get [email protected] on my LG UF770V, I’m using a CAC-1170 adaptor (mini dp 1.2 to hdmi 2.0), hdmi cable 18gbps 2.0 (have tried 4 of them), the last hdmi cable actually allows me select [email protected] without the need of adding a custom resolution in switchresx.

On the back of my tv it’s written [email protected], in the menu I enabled and disabled Lg Ultra Hd Deep Color, port 1 supports [email protected] (4:4:4, 4:2:2, 4:2:0).

When I select 3840 x 2160, 60 Hz (NTSC) HiDPI or the one without HiDPI the TV works ok, but shows 30hz, even in tv menu it shows [email protected]

In http://www.testufo.com I get 60hz, in About This Mac / System Report… / Graphics/Displays / it shows the resolution : 3840 x 2160 @ 60 Hz.

I have also updated the firmware for this adaptor with ps176b0_0x07.0x00.0x23_encryt_bank12.hex (you have no idea how hard it was to find a computer with a dedicated gpu, windows, mini dp port).

I have tried it on 3 macbooks (Late 2013 rMBP 15”, Mid 2014 rMBP 13”, Mid 2015 rMBP 15″), two tv’s (LG UF770V (my tv), LG UF850V (friend’s tv)).

The third cable which I have bought is : http://www.ebay.ie/itm/391324200976?_trksid=p2057872.m2749.l2649&var=660570922231&ssPageName=STRK%3AMEBIDX%3AIT

This is the last hdmi cable which I have bought http://www.adverts.ie/cables/gold-plated-2m-high-speed-hdmi-2-0-cable-full-hd-1080p-2160p-4k-2k-3d-for-ps3-lcd-dvd-hdtv/9152841?notification=75e0c281cb8392a6bd3d3f18ec045ac1-1462058125#comment_68183533

<p class=”p1″>Basically I can choose [email protected] but in fact the tv displays [email protected], even though the laptop informs me that the tv displays [email protected]

What else can I do ?

Thanks,

Daniel Asofiei.
