Acer is finally woken up and is paying attention to the gaming monitor Market
0:04
again they've dabbled in the past they had an at the time excellent 3D Vision
0:09
monitor the gd235hz but since then they
0:13
appear to have been sitting on their Collective thumbs until now welcome to
0:17
my video about one of the in my mind only two g-sync monitors that really
0:23
matters for high-end gaming the Acer xb280hk
0:34
Corsair gaming RGB keyboards feature Precision cherrymx RGB key switches for
0:39
16.8 million color per key backlighting for virtually unlimited customization
0:44
click now to learn more we'll start with a physical overview around this massive
0:49
28in 16x9 panel with the OSD controls
0:52
embedded in the bottom right is an unfortunately thick and glossy bezel
0:57
something I find particularly disappointing given how ahead of the curv aser was on
1:02
the super thin bezel thing when they released the h236 HL about a year and a
1:07
half ago the stand is a circular base affair with an orange accent it
1:12
assembles toolless Le in about 30 seconds and gives the xb280hk Tilt
1:17
swivel height adjust and pivot the quadfecta of ergonomic display
1:22
adjustment options it serves its purpose very well but I didn't find its build
1:27
quality particularly confidence in aspiring especially at this kind of a
1:32
price point although given that we know a g-sync module adds about $200 to the
1:37
cost of a monitor and Acer's offering is priced about $200 higher than otherwise
1:42
similar 4K displays that also don't feature beautifully overbuilt stands I
1:48
don't think Acer is cutting this corner any tighter than anyone else's on the
1:53
top bottom and right of the monitor is a whole lot of nothing but on the left
1:57
we're treated to two of the four usb3 ports that run off the monitor's
2:01
internal Hub then on the bottom we find the telltale signs of a g-sync monitor
2:06
aside from the usb3 Uplink the other two ports that go with it and an AC power
2:10
input we've got a whole lot of not much going on down here just a DisplayPort
2:15
1.2 input this is because NVIDIA's first
2:18
generation g-sync module only supports a
2:21
single DisplayPort input so then why would you want a g-sync module in your
2:26
monitor lonus great question g-sync
2:29
deliver smoother onscreen animations by eliminating screen tearing you know
2:34
those ugly horizontal lines through the image where it seems like the top half
2:38
of the screen has the last frame and the bottom half has a new one and leg which
2:43
is caused by your GPU waiting for the monitor to be ready for a refresh when
2:46
running with vsync on the way that we traditionally get rid of tearing but you
2:51
can learn more about it in this video here just trust me it works and it's a
2:55
pretty big deal but better perceived smoothness in gaming animation won't do
3:00
us any good if it's not presented on a good quality panel so let's have a look
3:05
shall we the xb280hk uses the same type
3:08
of panel that we've already seen before in the other loish cost 4K monitors that
3:14
we've covered here and here so there weren't really any surprises contrast is
3:19
pretty good color reproduction is surprisingly good for a TN panel and
3:23
pixel response times were good without excess ghosting and overdrive artifacts
3:28
even on fast moving scen as long as you leave the overdrive
3:32
setting at default within the onscreen display in fact I found most of the
3:36
settings in the OSD were best left alone I adjusted color temp to normal and
3:40
everything else especially the image profiles just made the screen look much
3:45
much worse so I didn't find myself using them in front of the flicker-free DC
3:51
controlled backlight we find a matte finished panel which is good if you hate
3:54
glare and reflections with horizontal viewing angles that are good enough as
3:59
long as you're sitting mostly centered in front of the screen the way most people use a computer the subtle green
4:04
and thin pink color shift is unlikely to bother you much on the desktop and is
4:09
pretty much impossible to pick up with a full screen game or movie running
4:13
vertical viewing angles just like the other low cost 4ks are less impressive
4:17
though with a noticeable gradient from warmer to cooler looking from bottom to
4:22
top even with your head in a stationary
4:25
position again this is something that's nearly impossible to pick up in games
4:29
and many people won't notice it at all anyway but I look at a lot of monitors
4:33
so particularly on uniform backgrounds like when reading emails or message
4:37
boards I find it a little bit distracting but let's change gears a bit
4:41
here and talk about the gaming experience I suspect if Acer could have
4:45
timed the release of their xb280hk 28 in
4:49
4k gsync gaming monitor any more
4:53
perfectly the entire world would have imploded 2 weeks ago the GTX 980 and 970
4:59
wouldn't have existed yet and graphics cards with enough horsepower to run
5:03
modern games at 4K would have started at $500 plus doar rather than 330 and they
5:10
would have been equipped with a mere 3 gigs of vram probably fine for now but
5:14
not exactly futureproof had Acer waited oh I don't know another year to release
5:19
this monitor we'd probably have better cards capable of running AAA titles
5:23
pinned at 60 FPS so the need for variable refresh rate technology that
5:27
masks stuttering when the frame rate DS drops would be reduced but as it is the
5:32
timing is great and this Monitor and those graphics cards are a match made in
5:37
heaven the way I benchmarked the xb280hk
5:41
was a little bit different than normal because it's mostly about the subjective
5:46
experience instead of firing up games and staring at my fraps counter then
5:51
dialing in graphic settings until the number looks good I went the other way
5:55
around I cranked everything to Max started turning things down until the
6:01
game felt 60fps smooth then fired up
6:04
fraps to see what frame rate I was actually running at even though I've
6:09
evaluated g-sync monitors before I've never done it this way and I think the
6:13
results May shock you I found that because of the pixel density of the
6:17
display anti-aliasing was Superfluous Beyond 2xmsaa which gave me more
6:22
Headroom to play with I candy options like tessellation and higher quality
6:25
shadows and to my surprise I discovered
6:28
that as long as my G wasn't falling below around 40 frames per second during
6:32
demanding sequences it was running to my eyes about as smoothly as if I was
6:37
running at 60 FPS constantly and this is
6:40
coming from someone who has gained for years on high-end hardware and considers
6:45
himself a bit of a frame rate Diva so
6:48
while I feel that lower cost 1080p g-sync monitors have a hard time
6:53
justifying that $200 or so premium compared to their non-gyn cousins
6:58
especially when that money could be spent on a better graphics card to keep
7:01
frame rates up or a higher resolution monitor to improve immersion and image
7:06
quality when you've already got a highres monitor the addition of g-sync
7:11
enables a smoother gaming experience with more details turned up than would
7:15
have conventionally been possible potentially saving you some additional
7:19
investment in more graphics cards this makes the xb280hk a very attractive
7:24
option for highend GeForce Gamers but
7:28
that doesn't mean that acers new beauty is the only horse on the track there are
7:32
two highres g-sync monitors that each bring their own unique value proposition
7:36
to the table this baby is the resolution
7:39
king and the only option for someone who wants a 4K display with g-sync today
7:45
while the Rog Swift from ASUS is an inch smaller diagonally and runs at a mere
7:49
2560 X 1440 resolution but delivers
7:53
thinner bezels slightly better colors and up to 144 Herz ref fresh rates so I
8:00
guess this is what it boils down to if you're a sightseer and most of your
8:03
gaming is done in third person or in casually competitive scenarios where
8:07
Lightning Fast Response times are not critical the xb280hk gets the nod if
8:12
you're looking for the best monitor on the Block for competitive play the Rog
8:16
Swift gets my vote for sure guys thanks
