Chapter in this post:
My nephew told me yesterday that he was about to get one 4K TV would like to buy for less than 300 EUR, which he would then like to misuse as a PC monitor. The price struck me as suspiciously cheap, but since he no longer knew the brand, I couldn't check where the catch was. The whole thing made me kind of puzzled and I felt a bit read into the topic "4k TV as PC monitor".to find recommended 4K TV models. Basically, the resolution of a 4K monitor is the same as that of a 4K television, but there are a few differences in the display that I have explained in this post. Important for the article: Ultra-HD, UHD and 4K are used synonymously here and are also the same in practice. The resolution of the devices is always 3840x 2160 Pixel. As refresh rate (fps = frames per second) you usually want 60 Hz or more so that moving the window or the mouse pointer on the television is also smooth.
When selecting the televisions below, I deliberately did not list any TV sets with huge displays, because most of the time you sit close to the "monitor" and then don't want to have a 55 inch screen in front of you - that would be like the 1st row in the cinema: impressive , but unpredictable. :)
DVI to HDMI conversion is always problematic
But if you have a PC, the one HDMI 2.0 output, you can usually get a 60Hz picture on the 4K TV. If you have a DVI output (mini Displayport) on your MAC or PC, you usually have to use an adapter or a special cable, but this again has the disadvantage that it only brings the 4K resolution over with a maximum of 30 Hz.
There is currently no adapter that can handle 60 Hz. There was once an adapter from ULTRA HDTV that supposedly was supposed to handle 4k @ 60Hz, but it didn't work for many people, so the manufacturer has obviously stopped selling it.
Update: There is one Mini Displayport to HDMI adapter from Club 3D, which also offers 4k at 60 Hz and works well according to customer reviews (thanks, Heiko!). And here also the adapter as DP to HDMI (Thank you, Busch!).
Update of this article about 4K televisions that should be suitable as PC monitors
Update, November 29, 2016: After consulting a knowledgeable reader (see comments), I have decided to revise this article. I have adjusted the list of suitable devices to smaller models and now offer you an updated list of good 4K televisions that are suitable as monitors for the PC. (For all those who are looking for 4K televisions that should only be connected to the computer from time to time, e.g. for gaming, I left the old list with the large models in the article.)
New list of 4K televisions that can be used as monitors
Now you have to see that the search for “small” 4K televisions is not that easy. The smallest models measure 40 inches in the screen diagonal, i.e. around 100 cm. The search filter at Amazon at least does not allow the selection of models up to 39 inches. So here are some 4K TVs with 40 inches and one with 43 inches, for those who sit a little further away;):
Notes on color subsampling or (sub) sampling
As you can read in the comments below, Marc pointed out to me that an important criterion for monitors is not addressed in this article - the sampling or subsampling, or in German: the Color subsampling. Unfortunately, this data is also missing from this update. I rummaged through the manufacturer's data sheets and also viewed the operating instructions if they could be found on the Internet. I have not found any indication of whether Y'CbCr 4: 4: 4 (high quality) or at least Y'CbCr 4: 2: 2 (medium quality) is used. - Update, November 29, 2016 end
4K TV with PC monitor potential
As mentioned above, the HDMI 2.0 input as well as one is required for a good computer picture on the TV Frame rate of 60 Hz or more important. 2.0K @ 4 Hz is not possible without HDMI 60 - even if the televisions are otherwise advertised for 4K operation. According to this specification, I have selected some 4K TVs that meet these criteria and that also have positive customer reviews:
- TCL U40S6806S (102 cm / 40 inches, Ultra HD, Triple Tuner, Smart TV) - here at Amazon.de
- Hisense H43MEC3050 (108 cm / 43 inch, Ultra HD, Triple Tuner, Smart TV) - here at Amazon.de
- Samsung UE48JU6050 (121 cm / 48 inches, Ultra HD, Triple Tuner, Smart TV) - here at Amazon.de
- LG 43UF7709 (108 cm / 43 inch, Ultra HD, Triple Tuner, Smart TV) - here at Amazon.de
- Sony KD-43X8305C (108 cm / 43 inch, Ultra HD, 2x triple tuner, Smart TV) - here at Amazon.de
If you have models in use that you can recommend, I look forward to your comment. Please make sure, however, that I only record devices that actually offer real 4K / UHD with at least 60 Hz.
