I can't get full 4k resolution to my TV from my main pc.

[Sorakaa]

I have a 4k tv and when i connect it to my pc from a hdmi 2.0 cable, i even tried a dvi to hdmi, it doesn't work.

for some reason it worked on my laptop though which was connected to the reciever, not directly like my pc.(yes i tried pc to receiver as well....)

I've tried this on a 980 and my new 1080.

my 3 display ports are taken up by monitors also.

I don't understand why it won't work.

also it only goes to regular 1080 60fps.

 

[jimmyEatWord]

maybe you gotta have a 4k hdmi cable ?

 

[greens]

I'm confused. Does it work or not? You state it doesn't work, but then there is this little note "also it only goes to regular 1080 60fps."

Can you clarify that when you plug in the 4k TV, that NOTHING happens - ie: It doesn't work.
Or is it stuck at 1080p?

Check your cable: https://turbofuture.com/computers/do-i-need-hdmi-cable-4k-hdmi-20-guide

He state he has a 2.0 cable. Additionally, any HDMI cable should be able to do 4k, just not at 60Hz.
So the cable, in this situation, really can't be the problem...

So this is the 4th monitor on the card? Are you maxing out your cards' supported output? If you unplug say 2 of your three DP monitors, does it work then?

 

[greens]

Good idea! I'd be surprised though, i can run 4 monitors at the same time, one of them being 4k, on my R9 390.

Have you tried setting the 4k tv to 30hz since you are using a HDMI cable?

3 3440x1440 monitors max resolution. I haven't tried it but i will when i get home.

 

[greens]

Yeah i think that solves it - you're maxing the cards output.

 

[Sorakaa]

Yeah i think that solves it - you're maxing the cards output.

so i'm screwed then? There isn't any way to use it?

 

[greens]

Not while using 3x1440p at the same time.

 

[Sorakaa]

Not while using 3x1440p at the same time.

can i buy some cheap secondary video card and hook it up to that?

 

[greens]

If you just need it to do 4k @ 60hz then yeah.
A GTX 950 would be able to ouput the 4k just fine, but it wouldn't be able to use the more powerful GPU's Horsepower.

well idk what happened it just started working I guess thanks everyone for the help anyway?

"So the cable, in this situation, really can't be the problem." Because cables never go bad, and all of the working 4K connections just happen to be using different cables from the receiver.

Check your cable means swap in a different one that you know is working.

Very fast protocols need to train up. If your connector or cable is marginal then it fails to train at 4K. After re-seating the connectors a bunch of time it now works -- maybe you got a spec of dust out of the way, that's all it takes sometimes.

Very glad it's now working. If it stops working consider swapping the cable.
