Laptop + 4k TV - Where is my bottleneck?

Since it's not mentioned that laptop likely doesn't have an HDMI 2.0 port, so no way to get 4K/60.

HD Graphics 620 doesn't do HDMI 2.0 without additional hardware so if they had added the necessary hardware they'd mention it.

Dear LTT - Community,

 

during the last christmas sales I have bought a new Samsung 4k 50'' TV. (50" Samsung UE50RU7092) LINK TO IT

//I wish Linus' video would have came out earlier :D

Either way, when I connect my laptop to it with an HDMI 2.0 cable, certified for 4k @ 60Hz, I can still only get a 30Hz output on my TV.

My Laptop is a Lenovo ideapad 520S-14IKB, 80X2 model. Link to the Laptop

As far as I know, it should have an integrated intel graphic chip.

Now I have two questions.

1. Is there any way, I can achieve a 4k image @ 60 Hz on my TV with this current setup?

2. If not, where is my bottleneck and what do you think would be the cheapest way to get there?

 

Kind regards and thank you in advance,

neomodd

could it be in the tv settings?

maybe it's capped at 30Hz.

I think some tv's had that where they could do 4k @ 60 Hz but it was set to 30 from stock because tearing or ghosting becomes visible at 60.

 

EDIT: The comment below makes more sense but still leaving this just in case.


Anything i've written between the * and * is not meant to be taken seriously.

keep in mind that helping with problems is hard if you aren't specific and detailed.

Make sure that you HDMI 2.0 cable is connected to a 4K ARC input.

Thank you for your fast answers! :)

 

I have crawled myself through all TV settings but could not find anything. I have Game Mode enabled and I am using the HDMI 1 port, which is a 2.0 port just like all the other ones. But it did not make a difference.

 

So I guess upgrading my laptop is my only choice to get 4k @ 60Hz ?
