How did you got it work at RGB 4:4:4 and Full Dynamic Range?
I can only choose RGB and full dynamic range,when i choose 4:4:4 i have only limited dynamic range which i cant change as its greyed out
Unless im missing something

I just did it in the nvidia settings, I have a 1080Ti if it makes a difference.

Can someone help me here, whatever I try I can't get past a 30FPS cap, it's in game mode and the screen info says 4k 60p when you press the middle button on the remote, but all games are capped at 30FPS no matter what settings I use.

looking at a 43 inch tv / monitor - how does the

SAMSUNG UE43MU6100 43"

fit into the scheme of things?

looking to play mmos like FF14 and ESO principally.

Anyone tried fps on this tv? was looking to pull the trigger on 40MU6400.

What graphics card are you using, and what type of cable?

I had an issue until I switched to Display Port with a DP > HDMI 2.0 adapter and a good quality HDMI cable.

Angerer · 28 Jul 2017 at 17:00

Ordered the MU6400

Tried it with two different cards and three different cables now. 1080ti and a 1070, three different HDMI cables, all good quality.

I'm not 100% sure what settings I need to use to get it to work, googling brings up nothing except a few similar but not the same sort of issues.

I received my MU6400 yesterday and had a little play, I noticed that I get a black screen for 2 or 3 seconds when watching youtube/netflix and also when clicking on Nvidia CP settings.

any clues whats happening?

I am using a 780ti and ordered a hdmi 2.0 cable from rainforest see if it helps.

New cable or do a clean re-install of your drivers.

I was having initital flicking problems which was sorted by the clean re-install.

Angerer · 30 Jul 2017 at 18:28

Cheers ReppyBoyo will try it.

Angerer · 1 Aug 2017 at 03:01

update.

I installed latest nvidia 384.94 drivers for my 780ti and now my tv is displaying "Mode not supported" ?

Do I too need a display adaptor?

cheers

*edit* I've pulled plug from mains and reset the tv back to original settings but still no luck, tv wont pick up pc anymore :/

This screen is not curved. Do we need a curve for a monitor of this size?

Angerer · 2 Aug 2017 at 22:16

Fixed my "Mode not supported" issue.

I am unable to run UHD Colour using my 780ti so just switched it back.

might try a display adaptor see how I get on.

Double check your refresh rate whilst in game mode on the desktop, try to manually set 60hz via display adapter properties > list all modes. If that doesn't work switch to PC mode, game mode is crappy 4:2:2 and not worth the IQ degradation imo.

My previous monitor (ultrawide) was curved. On moving back to a flat screen it actually appeared to be curving the other way and I struggled to get used to it - after a couple of weeks I stopped noticing.

LOL. So curve not needed really. Good to know. Thx.

How do these screens cope with 1080p input? I'm fine with 4K for my Mac but I've only got a lowly PS3 and it'd be nice to know that the upscaling (or whatever the technical term is) works like a charm.
