All you are doing here is talking about your personal view on using TVs as monitors. Not relevant to whether this is a good price for this monitor.

But colour accuracy costs money and yet you voted cold because it didn't fit your gaming use

You wouldn't edit photos or video on a 4K telly. These monitors are fantastic.

They're most certainly not "all just panels" - some 4K TVs are "faux-K" RGBW displays, some won't display a full 4:4:4 chroma input signal without downsampling, some have non-defeatable image enhancements which are fine for TV use but horrible for a PC monitor.

The right TV can work well as a monitor in the right circumstances, but it's not as simple as you're implying and you have to research the specs properly. Just buying any old 4K TV off the shelf in the belief that it's a cheap alternative to a purpose-designed PC monitor is likely to result in disappointment at best and eyestrain at worst.

Pretty old model now as released in 2014 (4K has come a long way since then) and looking at the forums this model had some teething issues.

this or the u2715 or up2716?

Sorry but cold, it's a lot of money for an old panel. For less than this you could have a newer 4K TV, which would be a lot more immersive for games, and is fine as a monitor (except perhaps where you need 100% colour accuracy) once you get used to the larger size screen....

Sure I mentioned that, but it's a niche case, only professionals in that field need perfect colour accuracy, for everyone else there are better value options...

such as for around £500? genuine question as that's my budget.

I did see this earlier on Amazon for £470, but I believe it has now increased to £570.99?

Most TVs, even cheaper ones, have a game mode that greatly reduces input lag, though I'm not especially sensitive to it anyway and can game on any preset and don't notice a great deal of difference between them (and yes I do play fast paced games, shooters racers, the lot), but if you are sensitive to it, the game mode should at least bring it closer to the input lag you might get on a monitor. It may never be quite as low, but there are always compromises and personally I always prefer more inches for the pound as I find the extra immersion of a big screen much more important than having lower latency or higher refresh, as for me regular TVs look absolutely fine already and I think the whole issue of input lag is vastly overstated, probably to sell fancy gaming monitors to PC gamers.

It was an issue when LCDs first came out in the early 2000s, even to unfussy me they had terrible lag and ghosting (I used to use a 2004 LG as a second PC screen), use one of them for a bit and even the lowliest budget TV will seem amazingly responsive. Issues of input lag were largely solved years ago IMHO....

Maybe you should open your mind a bit 'man', in fact maybe
you all should, it's just another option for saving money, which should be what
HUKD is all about. It won't work for everyone but for those with ample space
and want to be able to appreciate the pixel density of 4K it's another way of
doing it. Dunno why you all seem so closed and negative about the idea, it
really isn't crazy at all, they are all just panels at the end of the day, just
with TV panels you get more of it for your money.

Also, of course you can't get a 27" 4K TV but why would
you want such a small screen for 4K anyway? You can't really appreciate the
resolution of 4K on 24" and 27" screens, unless you have amazing
eyesight you have to turn the Windows scaling way up (150-200%) and then you
loose a big chunk of that desktop real estate, part of which makes 4K so great
to begin with. I'm not just making this up, I have used a 28" 4K monitor
and though impressive in itself, I found it too small for the resolution and had
to use high scaling and defeat most of the benefit. I switched to a 4K TV last
year and haven't looked back, I find it far more comfortable and now I can
actually USE all that screen real estate 4K grants.

This isn't all just opinion either, why do you think monitor
manufacturers actually make 4K PC monitors up to 40" now? They certainly didn't
for 1080P ones, it’s because the bigger screen helps you make the most of the
extra resolution! What do TVs have by default? Bigger screens, so a small 4K TV
as a monitor isn’t such a mad suggestion after all when some 4K monitors match
the size of entry level 4K sets….

I haven't argued against 40" monitors as personally I think they make good sense in certain circumstances.
I simply said that for typical home desks a 40" screen is not appropriate as it dwarfs the desk and for general home usage that much screen real estate is overkill.
But beyond that 40" is clearly a different class of screen than 27" regardless of resolution.
If someone posts a deal for a premium small car is there much point in stating that for the same price you can buy an entry level SUV that is much bulkier and lacking the features of the smaller car?

All fair enough, just mentioned as there might be people browsing threads like this that are just considering a 4K monitor in general, without a set model or size in mind, and I just pointed out another option, admittedly at the other end of the scale...

I'm a big fan of Dell monitors and I've been using the U3415W for 2 years, but unless I were desperate for a new monitor, I would hang on for the 2018 models that are already starting to appear.

I couldn't imagine I'd enjoy sitting in front of a 40" monitor using a PC, but for sitting back watching movies or console gaming it would be amazing!

But that's the user base these monitors are aimed at hence the price..
