4K HDR. Is it worth the investment?

I recently purchased a 4K 10bit HDR Monitor, the Acer ET430K, and without a doubt it’s lovely in 4K. But this week saw a much needed update to VideoLan (VLC), it now finally supports 4K and 8K hardware playback, something severely lacking in previous releases, even 4K playback was tricky and I used MPC-HC for that, now VLC also supports HDR too.

When I bought the monitor I also dropped £50 on a new BDXL drive (Asus BW-16D1HT), this will let me rip UHD movies to my WD EX4100 and play them back anywhere. I was initially surprised by the file size, they’re big, but only twice the size of a bluray at 1080p, yet they contain  four times the resolution, 10 bit colour (instead of 8 bit) and for the most part improved audio with more channels and higher resolution.

So I went to my local CEX and bought some UHD movies, The Hateful Eight, The Martian, Logan, and Alien Covenant, and after watching them initially in 4K SDR or 8bit colour I was a little unimpressed, but I was using MPC-HC to play them back, MPC-HC has hardware playback but no support for HDR, and at the time VLC didn’t. My initial misgivings were found-less, once VLC 3.0 launched I immediately saw the difference that HDR gives. I will say that 4K is very nice, but to be honest, it’s the difference with HDR that you’ll immediately notice. And all I can say is WOW. It’s HDR that will sell more TV’s and monitors than 4K alone.

Here are some screenshots from these films, sadly you really won’t be able to enjoy them as they are… you’ll need a 4K HDR screen.

What is HDR? Basically HDR (High Dynamic Range) means richer colours, more contrast and brightness this gives a scene better definition without losing details like increasing brightness and contrast will. It’s one thing that’s hard to quantify, but once you’ve seen it you’ll know it.

So does 4K 10bit HDR make a real difference… OH HELL YES it does. Be warned though, there are many 4K 8bit HDR screens out there, and they use software to push this to 10bit, they are severely lacking, they cannot and never will render 10bit properly. So be warned… don’t be duped into buying an 8bit screen, insist on HDMI 2.0 (this meets the bandwidth requirements of 4K HDR @ 50hz) and you should be ok, though always check with the internet before buying.

So is it worth the investment? For gaming on the PS4 and PC, yes it’s worth the entry fee alone. As for movies? HELL YES.

Another thing to consider, if you don’t use the TV’s built-in tuner or smart services then why bother with a TV, get a monitor instead. Monitors don’t have this stuff and as a result you should get a better image from it than a similar priced TV.

Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.

Dylan Thomas, 1914 - 1953

Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.

Though wise men at their end know dark is right,
Because their words had forked no lightning they
Do not go gentle into that good night.

Good men, the last wave by, crying how bright
Their frail deeds might have danced in a green bay,
Rage, rage against the dying of the light.

Wild men who caught and sang the sun in flight,
And learn, too late, they grieved it on its way,
Do not go gentle into that good night.

Grave men, near death, who see with blinding sight
Blind eyes could blaze like meteors and be gay,
Rage, rage against the dying of the light.

And you, my father, there on the sad height,
Curse, bless, me now with your fierce tears, I pray.
Do not go gentle into that good night.
Rage, rage against the dying of the light.
