My intent was to utilize the on chip video graphics to do this. 4k/UHD display standards are still emerging right now, so if you are planning to do the same do some research in advance. I also wanted to use a 40 inch TV as my monitor to save a few bucks and get up to the size I wanted to use (40 ). I don't need 40 of monitor, but with 4k/UHD pixel density and a screen that large, I can place my work windows in a position that does not induce fatigue after a long days work and have additional windows open around it with less used tools open and ready to go.
If you are pursuing the same, I will make some notes you can use to get boot strapped into this little conquest.
First, UHD and 4k are actually not the same resolution. This is lost on some TV related web sites and advertising. 4k resolution is 4096 x 2160. UHD is 3840 x 2160. UHD is what TVs and UHD content will support. UHD has 4x the pixels resolution of 1080i. So to put some of this in perspective, a 40 UHD TV has the equivalent of 4 20 HD (1080i) screens in pixels. And the pixel density of a 20 HD monitor will be the same as 40 UHD monitor.
The only interfaces that support full 4k/USD resolutions right now are Displayport and HDMI. The UHD TV's available right now don't support Displayport. I purposely bought a mother board that supports Displayport to keep my options open going forward.
You are going to need to find a TV capable of rendering the pixels without trying to enhance them for TV and Movie viewing. The Samsung I purchased supports just render /gaming mode if you learn about its odd setting requirements. LG has a few that support this mode and there are a couple of Chinese manufacturers that do as well (Seiki and TLS).
All of them overwhelmingly have HDMI 1.4 ports on them. They don't include this spec on spec sheets unless they actually support 2.0. Then they will brag about it as a feature. The notable difference between these two specs is the frame refresh rate. 1.4 supports UHD up to 30 fps, 2.0 supports UHD up to 60 fps.
Motherboard manufacturers are the same on this front and I cannot find any that claim to support HDMI 2.0. They are at least more transparent about the resolutions and fps rates they support with onboard interfaces for HDMI so a little less hunting to confirm they are unable to support 2.0.
The Displayport option supports @60 fps at 3840 x 2160 (UHD). So that is an option going forward whenever converters for HDMI are released that support HDMI 2.0. To do that I will still need to upgrade the TV.
I use this computer for work related tasks so I don't have to have 60 fps. I settled for a Samsung TV with hdmi 1.4 ports knowing I would be limited. This particular model uses a proprietary Samsung port that allows for upgrades after purchase to latest features and capabilities in an external box. Thats fine, and whenever Samsung offers this option with HDMI 2.0 I will purchase it if I think I really need it.
The on chip display is doing a very good job @30 fps. I am actually surprised by that given that it is still considered inferior to most reasonable pci video cards. I left room for a pci video card if I need to use one at some point. Right now I don't.
If you are using Linux with Xserver/Xwindows like I am, the Xserver will auto select the first resolution the chipset driver lists that is compatible with the resolutions the hdmi port reports. On my TV the hdmi does not list options to the OS. So Xserver picks the very first resolution the driver for the on chip graphics lists and that is 3840 x 2160 @24 fps. The TV refreshes @30 fps. This will cause the two to be out of sync on refresh rate. It won't be too obvious that something isn't right until you start to use your mouse or do something motion oriented like dragging something across the screen. It will have a lot of lag. Too much.
With tweaks to your Xserver configuration you can over
As a side note, as this is a K model and unlocked, it's made for overclocking. If you overclock, these overclock very well, but do tend to run a little hot over their previous iterations, so having a good aftermarket heat sink is a must (or watercooling if that's your thing). However, even if you don't overclock, having this model helps to future-proof your PC by allowing you to squeeze added performance out of the processor, and get you that much more use from your computer before you have to shove out more money for new parts. So I'd definitely recommend the K version even if you don't have immediate plans on overclocking.
I can't comment on overclocking as I don't overclock any of my CPUs.
