PC to UHDTV stuck at 60Hz

[EKuan]

Hello all,

So, I purchased a Samsung UN55JS9000; it's a 4k SUHD TV at 120Hz refresh. However, after my purchase, I learned that the TV does not run at 120Hz when connected by PC. I've tried both the DVI and the HDMI connections but I cannot achieve 120Hz refresh rate, stuck at 60 at the highest. I have read that this is the simply the way it is due to the cords or something like that, but there is a utility, CRU (Custom Resolution Utility), which can be used that will allow the TV to use its 120Hz refresh rate when connected to a PC. I have tried this over and over again to no avail. I have a GTX 980 and I've even tried to set the custom resolution settings, and I can enter the custom resolution for 120Hz at the 1080 setting (not 4K), but it always kicks it out and resorts back to 60Hz. Has anyone gotten this TV to work with either custom resolution settings or CRU? I'm not sure if I need to do something differently or if I should just settle for 60Hz while gaming and watching films at 1080. There has been quite a bit of chatter about this issue on forums but nothing has really helped me directly, possibly due to my specific model. In ideas on how to achieve 120Hz at 1080p with this Samsung television? Thank you.

Thats the trouble with marketing, sometimes they can be misleading.

No monitor today can do 4k @ 120Hz and certainly not HDMI. 60Hz raw input is what you're seeing, the 120Hz is internal to the TV to enhance motion.

Check product manual for supported resolutions.
I can tell you that it doesn't support 120Hz signals on any of available resolutions.

Hello,

Above is true for your TV, but not all of them.

Your TV cannot do 1080 120 Hz, though there are plenty of TV's that can. Here's one:

All the best!

That is what I was afraid of. I was attempting to get 120Hz at 1080p, rather than 4K, but I can't seem to achieve that neither. Looks like I will have to stream if I want the 120. Games still look great but I should have researched this matter further before jumping into the purchase. However, the marketing schemes got me, because I wasn't even aware that I needed to research it. I simply assumed that if I plug my PC in, I will get 120Hz, silly me.
