three years it was three long years ago
that I first laid eyes on the technology that would put OLED in its place and
I've waited since then for what would eventually become
the high sense u9 DG this is no normal
TV instead of one LCD panel filtering
the white backlight turning it into the vibrant content that you enjoy the u9dg
has two LCD panels in theory this unique
design gives it the best of all worlds near perfect blacks like an OLED and
vibrant Peak brightness for the best possible home HDR experience and
and it's already discontinued that's
that's tific because it means that you might be able
to score a deal on the remaining stock which appears to be now on clearance
making this video interesting for two reasons first to get deep under the hood
of a display Tech the world may never see again and second to maybe score a
deal perhaps oh and a third to learn about our
sponsor glasswire thanks to glasswire for sponsoring this video keep track of
the weird stuff that's connecting to your PC even when you are not using it
if a strange device joins your Wi-Fi you'll be notified instantly get 25 off
today using Code Linus at the link below the big problem with displaying HDR
content on LCDs is that even the best ones can't fully block out the backlight
behind them making black look like more of a faded out gray and the solution
thus far has been to divide up the backlight into multiple zones that can
be individually controlled to darken or brighten the image depending on the
content in front this works okay but
even on mini LED TVs with a thousand plus dimming zones the bloom or halo
effect around bright objects is almost always visible to the naked eye but what
if you had 2 million local dimming zones
this one doesn't it's only got 132 but
in front of those dimming zones is a
1080p IPS black and white LCD panel that
acts as a light filter and then in front of that is a 4K IPS color panel to
Output our final 75 inch image at refresh rates of up to 120 hertz doesn't
that add a lot more cost and complexity you might ask yes for everything packed
into it the u9dg is impressively slim but Hisense says that the bonding
process to fuse the panels together was extremely difficult to perfect and it
clearly contributes to the shocking 42 kilogram curb weight that resulted in
our first sample being damaged in shipping the good news is that it took
years but it was worth the wait the two
panel solution gives us an unbelievable amount of dynamic range on an LCD I mean
these are nearly OLED like blacks less
than .01 knits and it still reaches as
high as roughly 1100 nits in a five percent window and the best part is the
fineness of that control the 1080p monochrome panel doesn't quite
match the resolution of the 4K color one but if you need a pinhole of light in
the darkness it'll block most of the backlight strength before it ever
reaches the color panel and with over 2 million effective dimming zones the halo
effect is nearly imperceptible unless you put your eyeball to the glass
for reference we compared the u9dg to a
cheaper OLED and a nicer mini LED and
even though the mini LED had a whopping thousand zones of local dimming on a
smaller 65-inch panel the 75-inch
Hisense was hands down the best performer for HDR content did I even
mention yet that it has a quantum dot film and supports Dolby Vision so unless
you're in a light controlled environment where the OLED really shines it's just
wow and the u9dg is pretty color accurate too giving us an average Delta
e of 5.5 in IMAX HDR and just 2.3 in SDR
filmmaker mode similar to our LG mini LED and way ahead of our Vizio though it
too is still pretty respectable for a home display
a quick note for the high sense though if you want to get this crazy dynamic
range while maintaining color accuracy you'll want to use IMAX mode with local
dimming set to high now at this point everything is preceded as I had foreseen
but my big question for Hisense from day
one has been this going to add a bunch of processing
delay and totally Fubar the gaming experience
to find out we had to hook it up along with Ethernet USB ARCA a headphone
jack and Optical output the i o is solid with two HDMI 2.1 ports one with e-arc
and the u9dg supports variable refresh rate with AMD freesync as well as
automatic low latency mode which should kick in with any supported input device
that's promising for gaming but unless the pixel response times of the two
panels are darn near identical you could
end up with some really weird motion artifacts now Hisense says they solved
this getting both of them to a matching eight milliseconds but keeping them
synced up does require some extra work courtesy of their capable SOC with t-con
or timing controller we used an ldat then with an RTX 3080 on
our three TVs to test latency and
unfortunately the high sense does indeed
lose handily to the competition it's not the worst we've seen and they were at
least upfront about it eight milliseconds on the box should tell you
that there will be noticeable ghosting or motion blur but as long as the scene
isn't moving too fast your games will look gorgeous
like our new towels at lttstore.com at
this point some of you must be wondering if this performs as well as it does then
why is this the only TV on the market using this two panel Tech and why is it
already discontinued well first of all this TV is relatively
new but the technology isn't and there's a commercial mastering monitor from Sony
that actually uses the same idea the BVM
hx310 it came out in 2019 and cost a
whopping thirty thousand dollars at launch keeping it firmly in the hands of
the Hollywood Elite kind of like Chris Rock's face it can also do a thousand nits full
screen and it has insane color accuracy for film colorists by contrast pun
intended the u9dg was always intended to
undercut OLED for the consumer market and it launched at just three to three
and a half thousand US Dollars that's roughly a tenth of the price
but now mere months later you can already find it for just two grand at
Best Buy thanks to strong competition both from mini LED and new oleds from
both LG and Samsung as for why they're not being made
anymore our best guess is that it's due to production complexity and a
competitive landscape that looks dramatically different today than it did
three years ago when I first saw this demonstrated so with Sony's mastering
display being forever Out Of Reach of the general public and dual panel Tech
off of high senses public roadmap the u9dg might make more sense in a Tech
Museum than it does in your living room but if you can find it for a clearance
price and you need a huge TV mostly for movies with a little bit of light gaming
it's actually a pretty solid choice and the built-in Google Assistant Chromecast
and Alexa are all nice bonuses just like
