I am looking for a reasonably priced TV to use as a 4k monitor for my PC. I am not interested in gaming, but want to use it for general use and a bit of Photoshop too. I was hoping to use a Samsung UE40KU6020 which seems great value at the moment with all the Black Friday deals.
Main reason for new screen is to replace my 2 x 24" 1080p screens
I have seen the specification of this TV and it seems to have HDMI 2.0 so should run 4k @ 60hz I believe with the correct graphics card.
Can anyone recommend a graphics card for me to buy, again not interested in gaming so something that will run the 4k resolution on one screen (the TV) and let me do a bit of photo editing with Photoshop.
Thanks
Richard

What budget do you have for one and is noise a factor for you?

I guess budget is around £150 for the graphics card, could prob go a bit higher but don't want to spend more than I need to if a lower spec card does the job.
I'd ideally like it to be quiet as my PC is on for a large portion of the day.
Thanks

Pretty sure the gtx 950 is one of the cheapest options for hdmi 2.0

Thanks, they are in stock at my local Currys too.
Will this run a single screen at 3840x2160 ? I read that some cards only run across multiple screens

Yeah, it will do. At £100 it is a decent price. Would hope gtx 960 might get very close to that soon.

Thanks appreciate your help.
I also saw this one - https://www.amazon.co.uk/Palit-GeForce-1050-StormX-Graphics/dp/B01M7RRV7R/ref=sr_1_13?s=computers&ie=UTF8&qid=1480114810&sr=1-13&keywords=gtx+1050

Hi not had much time to look for a best price but this is the best type as it allows some room for "extra" so if you wanted to add a 2nd screen its no issue whilst running 4k at the same time.

Thanks. I'll take a look at this one too.
Appreciate your help

You don't want to be paying £100 for a GTX 950 when the newer RX 460 and GTX 1050 are the same price. I'd probably go for the RX 460 myself but it doesn't make a great deal of difference for your use.

There is displayport 1.2 to hdmi 2.0 adapter available.

I know you got your answer, but I'll just say you're in for one hell of a ride.

I just got a Samsung UE43KU6400 to use as a monitor on Wednesday and it's bloody glorious.

Previously had a 2560x1440p Dell Ultrasharp and an LG 1080p monitor, the 1080p failed, so I've now got the 4k, and turned the Dell to portrait mode running beside it.

Just a side note for you in case you have this issue. At first I could only get 30hz at 4k. This may or may not be an issue for you, but if you're used to 60hz on your desktop it may be noticeable. I had to go into the TV settings, Picture > Expert Settings > HDMI UHD Colour and enable it for the HDMI socket I was using in order to get 60hz working.

thanks, I put a 2gb gtx 1050 card through flubit and it's come back at £99 so I think I'll go with that.

thanks for the tip
now to head out and pick up the 4k TV :-)

Hi All, thanks for your help, just one last question !

I have flubit quotes for a 2Gb and 4Gb GTX1050 card now. Will I gain anything from the 4Gb memory or is this only required for gaming? The price difference is about £26.

Option 1 - Palit Geforce GTX 1050 2GB GDDR5 Dual Link DVI HDMI DisplayPort Graphics Card - £99
Option 2 - Zotac Geforce GTX 1050 TI Mini 4GB GDDR5 DVI-D HDMI DisplayPort PCI-E Graphics Card - £125

Thanks
Richard

The TI is a different card, but you could always spend that extra £25 and keep getting a slightly better card. I would just stick at £100 for what you want to do.

What is the drawback here? Are the response times terrible?

What is the drawback here? Are the response times terrible?

Technically yes, there are two types of lag at work. Pixel latency (also called response time) and input lag. Pixel latency is how fast a pixel can change colour, the lower the better. High pixel latency produces ghosting or motion blur where you might drag a mouse over the screen and see a trail behind it. Input lag is the time the screen actually takes to put the signal on screen that it's receiving. A high input lag would have you move a mouse and it moves on screen a moment later causing a bit of a disconnect between your actions and the TVs reaction.

Most computer monitors are made with low pixel response time (very typically 5ms and below these days), and most crucially, low input lag. They're made with immediate response in mind and it generally shows in pricing as well if you've ever tried to compare a 40inch TV and monitor as I did.

In a TV especially the more modern ones, you have the TV doing post processing trying to apply effects like upscaling 1080p content to 4k to take the jagged edges off of content etc.

Now in a movie scenario this isn't a problem, it doesn't matter if it takes 90-100 or heck even 200ms to display the signal it's getting from a Blu-ray player, you're none the wiser, the picture and sound are in sync and you watch the movie.

But with a console or PC, if you're playing a twitch shooter like COD or CSGO, or even playing a racing game where reaction times are noticeable, that extra lag will feel very unnatural, and even cause you to lose games.

Because consoles are quite a common livingroom device, TV manufacturers generally add a "Game Mode" preset to the TV which can be switched on and stops the TV trying to do any post processing.

Websites like displayspecifications.com and rtings.com try to provide information about input lag on various models. Also hdtvtest.co.uk/ but their database is a bit smaller than the other two.

For screen latency, assuming we aim for the 60fps gold standard, 1 second = 1000ms. So for 60fps 1000/60 = 16.6ms. Any screen with a response time or latency of 16ms or less will display 60fps without a problem.

For input lag, obviously the lower the better, and opinions vary, but I did see a few places mention that an input lag of 40ms or below is really best for gaming.

I'm using a 43inch Samsung 6400, and although I couldn't get specific numbers on its input lag, I was able to use this comparison http://www.displayspecifications.com/en/comparison/44ee7fe6 to its sister product and was reasonably satisfied that it would perform the same.

I've been playing Rocket League and Rainbow 6 Seige on it, both quite reaction time based games and haven't felt any difference from my previous Dell 25inch Ultrasharp monitor.

Anyway I've banged on long enough, hope that helps. :)

Quick update, I purchased the GTX1050 card and also picked up a Philips 40PUT6400 in the Richer Sounds ex-demo clearance for £239.
Finished product is great, I'm really pleased. Thanks all for your assistance on choosing the graphics card.
TV is running 2160p 60hz and 4:4:4, text is crisp and sharp and colours are vibrant.
Just need to calibrate it now with the colormunki.
