4K60 signal to TV over HDMI problem

Well that explains why your friend thought it looked good :) just wanted to make sure . :)

I think for gaming AMA on high was suggested too.

Yes I think it was the modified settings rather than the factory defaults, my bad.

I set the AMA to "high" too but I pretty sure I wouldn't be able to tell these differences.

i think i had to set my DP input to 1.2 on the bl3200 monitor to get it too work with my 970 , that happen with the 1070?

I haven't tried the DP as the cable that was included was quite short and I'm using the included DVI cable now. It worked just fine from the start as it did with the AMD 280X which I used previously, and even the GTX 275 that was used briefly.

Wish the TV had DP or DVI... wouldn't be here maybe.

The cables with the BenQ 3200 are really short , apparently 6ft is not the same measurement everywhere :)

your geforce post

The 59/60 hz thing mentioned at Geforce is a windows thing and a known issue , it is in NV notes and they link to this M$ KB about it

https://support.microsoft.com/en-us/kb/2006076

your pics here show it at native Res. however your Speccy pic shows it at the same res as the BenQ , which maybe why the TV doesn't see the signal ?

Did you clean out ALL AMD and Nvidia Drivers with DDU before installing the 1070 Card ? looks like something is messed up

Update (23th of August):

I went ahead and also contacted MS support phone (and got surprisingly friendly answers). I did a complete reset to the system (other reasons besides this, too). I'm in the process of updating windows. I'll then get the proper Nvidia drivers ands see if there's any luck connecting the TV.

Edit: MS support said that I should 1) try the non-AU version or 2) just wait as this is "still very new" for the manufacturers.

Update (27th of August):

1) After clean Windows 10 reset - not working, the basic driver doesn't recognize the TV on the GPU HDMI output.

2) Tried installing previous Nvidia drivers, 368.something manually. Says it isn't compatible.

3) Windows fails it's attempt to install "a GTX 1070" driver repeatedly. Computer is essentially bricked unless I manually initiate the anniversary update.

4) After AU with basic Windows drivers - nothing.

5) After installing the 372.54 drivers - GPU is recognized porperly, so is the second HDMI output to TV. All the display settings in the NCP and Windows display settings make sense - all resolutions and frequencies are reported correctly. TV still says "no signal". Everything works perfectly on the main display (BenQ BL3200PT), all games run flawlessly.

6) Tried all the different settings from NCP while the resolution was set to 3840x2160 @60Hz (native) - no signal.

7) Tried to switch off "HDMI Ultra Deep Color" from TV. TV is now seen to the computer as a 1080p native display and it works, the desktop is seen at the TV. But at 1080p.

8) Tried to set the resolution to 3840x2160 @60Hz from NCP - no signal. All other also "no signal". Ultra deep color "off".

9) Switched the ultra deep color setting on again. Everything back as in the beginning - "no signal". Back to square one - things the same as before the reset and the first clean install.

Looks like GreyBear is giving good advice at

I would probably try a custom resolution through the NCP since you can get HD , just not UHD
and
Call LG and see what they have to say.....or did you do that already?

To anyone interested - it seems that this thing is over. Check the quoted thread over the Nvidia forums.

Well, it essentially came down to not checking the HDMI cable even if it's brand new.

Respectable effort for solving a problem that wasn't even there, from all sides of the discussion :)

A USB problem remains now. If that would go away, then I could say the two-week old computer works 100%.
