The World Cup has started and although you can watch it in Ultra HD quality, I’m urging you not to.
In the UK, you can watch the tournament in 4K – at least for certain matches. This is because only BBC iPlayer has this feature and the other matches being shown on ITV will just be in HD.
Even then, you need a compatible TV or streaming box to get UHD on iPlayer (I’ve written a full guide here), but that’s not even one of the three reasons I think you should avoid doing it for the World Cup 2026.
Let me explain…
It’s not live
This doesn’t just apply to streaming in 4K but is made worse by the fact the higher quality makes it more likely to occur.
The problem is that streaming a World Cup match via a service like iPlayer means you’re not actually watching the footage live. There’s a delay vs a broadcast signal – particularly compared to watching Sky via satellite – so you could be watching as much as a minute or more behind the action.
And that’s even if you have super-fast internet and a speedy mesh Wi-Fi network, though those with poorer connections are also more susceptible to buffering and similar issues.
BBC
This might be ok for some, but it comes with a high risk for many viewers. Primarily, you could easily be notified about a goal or other major event before you see it happen on the screen.
You might hear neighbours cheering, you might get an alert from a sports or betting app on your phone or see posts going viral on social media.
If you want a true, spoiler-free, truly live World Cup experience, then avoid streaming.
I can’t see properly
We’re typically led to believe that watching content with various fancy standards is inherently better and this is true of HDR – it promises a more vibrant, colourful and lifelike viewing experience.
However, that’s not always the case and there’s one big downside to streaming content in 4K HDR on BBC iPlayer.
The app uses HLG (Hybrid Log-Gamma) as its default (and only) HDR standard, but even if your TV supports it – many do – you might be better off avoiding it.
Countless viewers, and I’ve experienced it myself on many occasions, report that the picture is very dark. This is not ideal for watching football and though you may be able to correct it with some settings, no one wants to have to deal with that kind of faff at kick-off, especially if you have got guests over to watch the game.
It’s not even real 4K
This feels bizarre to say in 2026, but the World Cup 2026 isn’t even in proper 4K quality if you watch on BBC iPlayer.
Despite 4K, not to mention 8K, TVs being around for well over a decade, the amount of true 4K content is still surprisingly and frustratingly sparse.

It’s bad enough not having proper 4K channels and having to jump through hoops on iPlayer (nothing on ITV is 4K), but this year’s tournament isn’t even being streamed in real Ultra HD.
Instead, the source material is HD and it’s being upscaled to 4K. Something your 4K TV will almost certainly be doing if you watch a game on BBC One, regardless.
Whether one is better than the other will depend on various factors, but when you combine this issue with the two above, you’re best off just watching in the old reliable way.
Switch your TV on, find the right channel, and enjoy.
