TCL 4K TV running in 2160p30hz?

[Fellanah]

I bought a TCL L43P2US 4K TV but the max I could get out of it was 30hz. I am not sure about if the TV uses HDMI 2.0 or not so I can't really tell about that. For my htpc I am currently using a g3258 paired with a gtx 660(which I think could be holding it back as I am using HDMI, it has display port though, think it could work? I don't have a cable with me right now so I can't test it) I am a little hesitant on buying a gtx 950 as I read somewhere it can do 4k60hz but I would like to know what you guys think I should do. Thanks in advance!

GTX 660 is HDMI 1.4 only, so 30hz is the most you can get out of straight HDMI from that GPU.

There are DP to HDMI 2.0 adapters that will do the trick, but they're not cheap: https://www.newegg.com/Product/Product.aspx?Item=N82E16812400859&cm_re=displayport_to_hdmi_2.0-_-12-400-859-_-Product
Cheaper than a new GPU though.

However, you want to make 100% sure that your TV is indeed HDMI 2.0 before handing over cash for that adapter. It won't do anything if your TV is only HDMI 1.4.

Did you want audio pass through over HDMI too? That complicates things further.

DP can do audio but it's not guaranteed. I don't know whether your 660 can send audio out the DP port. That adapter I linked says it'll pass digital audio too. But I don't know whether the 660 can do it.

Yeah that's the thing, I am not entirely sure if the TV is HDMI 2.0 and that would SUCK if it didn't. By the way, audio isn't a problem for me, I would just really want to display to work as it should. I have emailed them and I am waiting for a reply whether or not the TV is HDMI 2.0. Other than that, is there anything else I should do?
