4K Display help needed

[Karatedude55]

So my dad and I just got 4K 60hz TVs to use as monitors. I got mine up and running just fine but my dad is having issues.

My dad connected his TV to an HDMI 2.0 cable, then to a displayport 1.2 adapter, and into his GTX 760. He cannot run the TV past 30hz. I know that the cables are not the issue, because I am using the same ones in my setup.

We have tried updating the drivers for both the TV and the GPU, but it still not will run past 30hz

Note: when set to 60hz, a white screen is displayed. Also, we both know very well that a GTX 760 will not game at 4K, we are planning on buying a new GPU, so please do not mention that. Also, I have an MSI R9 390 and he has a MSI GTX760

*Disclaimer* I am by no means an expert on the subject, just trying to be helpful.

what version of windows on both pcs?
I noticed that you have a AMD video card and he has an Nvidia card. Ensure your dad's drivers are up to date.
And did you both get the EXACT same tv? All those letters in numbers in the model name indicate different nuances and features in each tv. I am only familiar with Samsung but there are a lot of different features that they can put in or leave out of a tv that seriously varies the price.

Some things you may need to check for your dad:

The exact specs of your card.
How much memory does the card have? It might not be enough to run 60fps
If that specific card even supports 4k at 60fps.
I do not believe 4k was even on the horizon when that card was made if my memory servers correct. You'll need to check both NVidia and MSI.

Hopefully this gets you pointed in the right direction to fix your issue. When you do go to purchase new GPUs, make sure you research thoroughly what you need, don't just go off of price cuz that can lead you to purchase something that seems good at first glance but doesn't allow you to do everything that you want the card for.

This is a link to AMD and NVidia GPU comparison chart that lists them from top to bottom in order of performance. As of now, your card is in the 4th highest tier and your dads is in the 7th highest tier. Your card has a good bit more horsepower than your dads, which means it has enough brains and muscle to run 4k at 60fps. At first glance I'd say your dads card is just under what is needed for 60fps.

NVidia indicates their cards general performance level by the number in the 10s column. Generalizing again, low is the 10-30, mid is 40-60, high is 70-90. Your dad has 760 which is the high end of the mid range of the 700 series of card, and what number most people end up getting as those are usually priced in the $250 range and you get good performance for you money. I ended up buying a 770 back then because I wanted a high end card and that's what I could afford. AMD has a similar scheme but I don't buy or their cards so I cant explain their system to you.

Looking at the amazon page for your dads card, it was originally design to max out at a resolution of 2560 x 1600 which was pretty badass in 2013 but not quite as demanding as 4k is since it is obviously a smaller resolution. It may just turn out that your dads card can not run at 60fps. If you do upgrade him to a 1060 or 1050ti if he is just using the tv as a monitor. If he does plan on gaming, you'll need to look at a 1070 or higher (or whatever the AMD equivalent is) depending on his graphical taste. If you want a solid 60fps for gaming at 4k, you'll have to spring for a 1080ti or 1080, the 1070 can game at 4k but not on max graphical settings while maintaining 60fps.

Thank you to those that responded. We actually went out an got an RX580 for him today, and it now works perfectly fine. I assume that it must have been a compatibility issue with his old graphics card.
