Running 4K

[TheRenegan]

Hi guys, i`m delaing with a problem for quite a while. I bought a 4K 3D TV ( a Philips Smart TV 40PUS6809 102 cm) and i had a hard time trying to make my PC display any image on the screen. I made it work on a FULL HD 60 Hz setting, until a couple of days when i tried to see a 8K image on the TV. I noticed that the TV cannot run any image above FULL HD. It simply take 2 corners of the image, overlaps them and shows them on the screen. I didn`t figured out what might be the problem. I tried then running my deskop at 4K and i finaly made it but only at 23Hz. Everything above it makes the screen go black.

My question is now, if it`s possible, how can i run a game in 4K? Because everytime i change this setting in game it doesn`t work. Again, it makes the screen go black.

I`ve done my research and i now it`s a real strugle even for high-end video cards to run 4K games, and i know if i can make a game run in 4K it would probably be at 5-6 FPS max...but i want to know what must i do to make the TV accept a 4K resolution from a game.

I would realy apreciate any help.

Like i said, i don`t expect to play Crysis 3 on full settings with this specs, but i just want an explenation of why can`t a game stay in 4K resolution when i aply it.

You couldn't play minecraft at 4K with those settings

You`re going offtopic. You  didn`t even read what i was asking ...

Dude your specs aint strong enough. As @ANewFace said, not even MC

I'd just run the game at 1080p and stretch it across your screen. Your frame rates and detail settings will be WAY too low for 4K.

[TheRenegan]

I don't think your graphics card can support a 4k display with any of the display outputs on the back of your card. I'm not sure what version of HDMI your card has, but I don't think it can do 4k. Also, based on what I see on Philips' website, I don't think that your TV is capable of doing 60hz. I think the most it can do is 30.

strange because at a 1920x1080 resolution the TV only works at 60 Hz. After some long battles i found out that at 4K i have to put it on 23 Hz to work.

 

But how can it display my desktop at 4K and not with a game...i just want to know some information.

What cable are u using to connect the tv to your gpu?

every game works just fine at 1080p and it looks great... i was just curious if i can see how games look at 4K.

1) you CANNOT run 4k with such weak hardware...

 

2) your GPU doesnt even support HDMI 2.0 so you cannot do 4k at 60Hz, and it is probably your cable that is cheap and limiting your bandwidth

the HDMI cable must be plugged into an HDMI or mini HDMI port on your GPU

[TheRenegan]

HDMI.Only in the port 4 of the TV. The other 3 won`t work with a resolution bigger than 1080p. It mentions it in the instruction book and check it myself

everything is posible...i haven`t payed like a billion dollars on the cable. and i haven`t done any deep research on my video card eighter

[Fgtfv567]

Friend. Trust me. A 650 Ti OC is not strong enough to play games at 4K with an acceptable frame rate and detail settings. Either play your game at 1080p and stretch it out at 4K, or get a better GPU. I don't have any more advice for you.

Dude this

The 650ti doesn't support 4k @ 60hz. It doesn't have displayport or hdmi 2.0, so the maximum it can do is 4k 30hz and ONLY on the hdmi port. That is regardless of how fast it is. It won't output at that resolution and framerate. Ever.

 

Cables have nothing to do with it, digital cables are all the same if they work. They either work or they don't there's no inbetween. The gpu is just insufficient.

but what makes the deskop different from a game?

I mean what is the GPU doing when it displays a 4K resolution on a dekstop and what is it doing when it displays a 4K resolution on a game?

 

I`m sorry if i sound stupid asking this things, but i want to understand as much as i can. I don`t want to play any game on the TV, i barely use it...i just want to understand how things work at this chapter.

In games the GPU needs to render 2D images from 3D positioning information, and this takes a lot of computation power which isn't required on the desktop.

 

If you stay out of games, the 650 Ti will handle 4K just fine on the desktop, for browsing and movies things like that. High GPU power is only needed in 3D applications. People seem to forget "running" a 4K monitor is not the same as "gaming" on a 4K monitor. Running a 4K monitor takes hardly any GPU power, the desktop is child's play at any resolution on modern GPUs, even integrated graphics.

[GoodBytes]

Yes. It must be noted however that most (both mobile and desktop together) Intel integrated graphics can't do 4K 60Hz even if you have DisplayPort. You need the higher end and newer ones to be able to do it, Check Intel website for compatibility.

 

As for the OP case, the 650Ti doesn't have the outputs needed for 4K 60Hz, but 4K 30Hz is fine via HDMI.

Ok i understand now. Thanks a lot guys.

HDMI (like every connector) has a bandwidth limit. That bandwidth only allows a MAX of 4k images every 1/30 seconds. Therefore the connection is not fast enough for the card to send 4k signals at 60hz. As for gaming, when you're playing a game the gpu has to make a LOT more calculations than when it's showing the desktop. This is because the desktop is mostly in 2d, games are in 3d and objects mvoe aroud constantly and need to be rerendered with all the filters and textures needed. Still, that has no impact on the maximum output resolution and frequency. You will just be seeing the same fram for multiple refreshes if you dip below 60. At 4k rendering  game becomes very hard because the amount of detail visible on screen is much higher than what is visible at 1080p or even 1440p, therefore a lot more stuff has to be rendered. Also, more textures are visible and need to be saved in the vram, if the vram is not large enough you hit a giant performance wall and loose 90% of your framerate as the game tries to load textures from your hard drive..

You may have to create a custom resolution in the nvidia control panel and set 30hz that way.  Not sure about it but may as well try it if nothing else is working.

Ahh I wish more people would understand this.  I got practically ripped apart for saying I wanted to hook up a 4k monitor to my 570 via hdmi for extra screen space, even when I put specifically in the op that I wouldn't be gaming on the thing.
