Hello all :)

 

I bought a 4k TV so i could plug my PC into it.

 

I use a gtx 970

 

https://www.amazon.co.uk/d/5fn/Samsung-UE40KU6100-Smart-Curved-Ultra-HDR-inch/B01LZUKKLC

 

How can i figoure out my TV's refresh rate? Tried to look for it but cant find it.

 

When i put the 4k on the screen means laggy, Im assuming this is down to the GPU.

 

Any help would be great :)

I'm assuming it's 60Hz, though it's actually not that, because TVs do some complicated frame copy/swap/modify thing or something.

It will likely be 60Hz without any funny business. It's when you see the 600Hz effective refresh rate that they're using back-light strobing and post processing to get the bullshit numbers.

60Hz, with trickery to "simulate" 120Hz http://www.samsung.com/latin_en/tvs/uhd-ku6000/UN40KU6000HXPA/  Tvs tend to have really bad response time compared to monitors and yeah some lag from the 970 not being able to power 4k in graphically demanding situations (and maybe that 120Hz trickery messing with you, should be an setting to turn it off somewhere)

So I'd assume it's really 60Hz.

hdmi 1.4 can only do 30 Hz on 4k

hdmi 2.0 can do 60 hz

maybe the hdmi cable is not good enough for hdmi 2.0 ?

Is your TV equipped with hdmi 2.0 inputs?

 

maybe your card is only hdmi 1.4? (it should really be hdmi 2.0)  - if that's the case you can get displayport to hdmi 2.0 converters for around 10-20$ which convert displayport to hdmi 2.0 that can do 4k at 60hz

Most can do 60hz (assuming its 4k via HDMI 2.0)

Very few tvs have faster native refresh rates without interpolation. Some 240hz TV's have 120hz panels. These aren't widely documented.

It is a 60hz panel. For using with a PC, you'll want to turn off all its filters/interpolation/processing that you can to reduce latency. Turn on game mode, and you should see a large improvement: http://www.samsung.com/us/support/answer/ANS00041431/

 

Check what refresh rate it is detecting at under display settings > advanced> display adapter properties> monitor on Windows, to make sure it is at 60hz.

that's a different panel than the one OP has. He has a KU6100 varient, not KU6000

how embarrassing I don't know what went wrong, typed in "samsung ku6100" and the top listing was purple and I believe it sent me to the right place this time http://www.samsung.com/uk/tv/KU6100/   and...doesn't list refresh rate and the links to download the manual and got to the support section don't work in any browser I have..... good work on your site samsung
