Speaking of G-Sync monitors, Acer has announced a 4K monitor ahead of Computex with NVIDIA's adaptive refresh rate technology. While they do not ever say that it is 60Hz, I believe that it is. It also seems to be based on a TN panel. It, being G-Sync, connects with DisplayPort 1.2 and also includes four USB 3.0 ports. It, however, does not seem to support the competing AMD's FreeSync, integrated into VESA's DisplayPort 1.2a standard.
We do not currently have an image of the monitor
4K could be where we really start seeing benefits for G-Sync. At that resolution, it is very difficult to get a system, regardless of how many GPUs are inside it, which can play the most modern of games without dipping below 60 FPS. Once you miss your 16.67 millisecond window, your game starts hitching between images living 33.33ms and 16.67ms, when each frame is supposed to be presented at a constant rate.
As for pricing and availability: Q2 (early May to end of July). That's all we know.

You might remember the ASUS PQ321Q 4K monitor from last year that we loved. It was based on an IGZO panel and allowed for 60Hz via one DisplayPort 1.2 cable, running in Multi Stream Transport (MST). At Computex 2014, ASUS announced the PA328Q. This "ProArt" panel ships calibrated and offers 10-bit, 100% sRGB color representation. More interestingly, it supports HDMI 2.0 as well as DisplayPort 1.2, for 4K at 60Hz, apparently over a single cable.
The monitor also has an extra mini DisplayPort connector and two HDMI 1.4 inputs. Also, four (4) USB 3.0 ports and a headphone jack. I guess professionals like high-speed removable storage.
Some points that I would like to see clarified are:
- its Adobe RGB coverage (for printer color spaces)
- its panel type (I expect IGZO)
- and its pricing (and availability)...
I do not know how this fits in to the ASUS product stack, relative to the $3500 PQ321Q. It includes more modern connections and could hit the checkboxes for digital content creation at 4K. Its price might give us an idea about where it stands... or it might just blow our minds, one way or the other. For now, I don't know.

4K for $649
The growth and adoption of 4K resolution panels (most commonly 3840x2160) has really been the biggest story of the past year or so in the world of PC gaming. After a couple of TVs that ran at 3840x2160 over HDMI at 30 Hz found there way into our offices, the first real 60 Hz 4K monitor that I got some hands on time with was the ASUS PQ321Q. This monitor was definitely targeted at the profressional market with its IGZO display (near IPS quality) and somewhat high price tag of $3500. It has since dropped to $2400 or so but it remains somewhat complicated by the use of MST technology (multi-stream transport) that was required to hit 60 Hz.
Earlier this month I took a look at the Samsung U28D590D 28-in 4K panel that was capable of 60 Hz refresh rates for just $699. This display used a single-stream transport DisplayPort connection to keep setup simple but used a TN panel rather than IPS/IGZO. This meant viewing angles were not as strong (though better than most TN screens you have seen before) but...that price!
Today we have our second low cost, SST 4K monitor to evaluate, the ASUS PB287Q. We saw it at CES back in January and with a launch date of June 10th and an MSRP $649, ASUS is setting itself up for an impressive release.
So what can you expect if you purchase the ASUS PB287Q 4K monitor? In short you get an adequate screen that won't live up to IPS standards but is just good enough for the PC gamer and productivity user in all of us. You'll also get a form factor that well exceeds that of the Samsung U28D590D with fully moveable stand and VESA mounting. And a price of $649 for a 3840x2160 screen doesn't hurt either.
Read on the next pages for more details on the user experience in Windows 8.1 as well as while gaming to see if this is the right monitor for you to buy this summer!

We've been talking about the benefits 4K for a while, most recently with the Samsung U28D590D, which added single-stream 60Hz support to the mix, but there have certainly been some drawbacks with 4K monitors to date. Between usually low refresh rates and the general problem of getting smooth images on the screen (not to mention the high price of entry into 4K) there have been some legitimate questions about when to upgrade. Well, an interesting new product announcement from a surprising source might change things.
With a logo like that, who needs product photos?
Today, Acer is announcing an interesting alternative: the world’s first 4K monitor with integrated NVIDIA G-SYNC technology.
The XB280HK will be a 28" display, and (provided you have an NVIDIA graphics card and were looking to make the move to 4K) the benefits of G-SYNC - which include minimizing stutter and eliminating tearing - seem ideal for extremely high-res gaming.
We’ll be eagerly awaiting a look at the performance of this new monitor. (Or even a look at it, since Acer did not release a product photo!)
The details are scarce, but Acer says this will be a part of their “XB0” series of gaming monitors. Here are some specs for this 28” 3840x2160 display, which features three proprietary technologies from Acer:
- “Flicker-less” which Acer says is implemented at the power supply level to reduce screen flicker
- “Low-dimming” which sounds like an ambient light sensor to dim the monitor in low light
- “ComfyView” non-glare screen
Of interest, the Acer XB280HK is likely using a TN panel given the claimed "170/170 degree" viewing angle.
The hardware needed for good 4K frame rates are definitely up there, and with G-SYNC onboard the XB280HK will probably not be in the low-end of the 4K price range, but we shall see!
3840x2160 for Cheap!!
It has been just over a year ago when we first got our hands on a 4K display. At the time, we were using a 50-in Seiki 3840x2160 HDTV that ran at a 30 Hz refresh rate and was disappointing in terms of its gaming experience, but impressive in image quality and price ($1500 at the time). Of course, we had to benchmark graphics cards at 4K resolutions and the results proved what we expected - you are going to need some impressive hardware to run at 4K with acceptable frame rates.
Since that story was published, we saw progress in the world of 4K displays with the ASUS PQ321Q, a 4K monitor (not a TV) that was built to handle 60 Hz refresh rates. The problem, of course, was the requirement for a multi-stream connection that essentially pushes two distinct streams over a single DisplayPort cable to the monitor, each at 1920x2160. While in theory that wasn't a problem, we saw a lot configuration and installation headaches as we worked through the growing pains of drivers and firmware. Also, it was priced at $3200 when we first reviewed it, though that number has fallen to $2400 recently.
Today we are looking at the Samsung U28D590D, the first 4K panel we have seen that supports a 60 Hz refresh rate with a single stream (single tile) implementation. That means that not only do you get the better experiences associated with a 60 Hz refresh rate over a 30 Hz, you also gain a much more simple and compatible installation and setup. No tricky driver issues to be found here! If you have a DisplayPort 1.2-capable graphics card, it's just plug and play.
The Samsung U28D590D uses a 28-in TN panel, which is obviously of a lower quality in terms of colors and viewing angles than the IGZO screen used on the ASUS PQ321Q, but it's not as bad as you might expect based on previous TN panel implementations. We'll talk a bit more about that below. The best part of course is the price - you can find the Samsung 4K panel for as low as $690!

We’ve seen what happens when you put two monstrous graphics cards together with Ryan’s look at a R9 295X2 CrossFire setup and now here’s something that would challenge even that: Crysis 3 at 8K resolution!
An enthusiast called "K-putt" has created a hack to allow the 8k setting, and his Flikr gallery has full-res versions of the screenshots. (Be warned - they're HUGE files!) While this likely isn’t practical even with a quadfire setup like we had for those tests (K-putt was only getting 2 FPS with his single-card setup), it’s still very nice to look at!
The original Crysis became famous as the game that would bring any system to its knees, and now any game can really challenge a system just by adding a 4K monitor. With prices coming down to the sub-$700 range already it won’t be long until a multi-4K monitor setup will actually become feasible.
Here's what comes up under "4k monitor" on Amazon today:
Prices are dropping! Just be warned: Before attempting anything like this you’d better have the GPU horsepower or it’ll just be a (very pretty) slideshow!

Early last month, AMD launched a new flagship dual GPU graphics card called the Radeon R9 295X2. This new card features two Hawaii-based GPUs paired with 8GB of GDDR5 memory. Since the launch, several partners have come forward with reference cards of their own. One piece of the "world's fastest graphics card" puzzle that has been missing, until now, is a vendor daring enough to take the beastly R9 295X2 and push it even further by offering up a factory overclocked edition. It looks like Sapphire is the first to attempt such a feat by offering up the factory overclocked Sapphire R9 295X2 OC.
The upcoming Sapphire card will join the existing reference design R9 295X2 and ratchets up both the GPU and memory clockspeeds. Sapphire is clocking both Hawaii GPUs at up to 1030 MHz and running the 8GB of GDDR5 memory at 5.2 GHz. These factory overclocks are modest from a numerical standpoint, but considering cards running at stock clocks of 1018 MHz for the GPU and 5.0 GHz for the memory are already pushing a 500W TDP and over the ATX PSU spec, seeing any overclock is notable.
In all, we are looking at 5,632 stream processors (Hawaii architecture), 128 ROPs, and 352 TMUs. Each GPU uses a 512-bit bus to 4GB of graphics memory. This factory overclocked graphics horsepower rounds out to a smidgen more than 11.5 TFLOPS of single precision performance.
Sapphire is utilizing the same hybrid heatsink design as the reference cards which uses a centered fan and fin stack along with a AIO water cooler with a 120mm radiator.
Sapphire has not released pricing or availability on the overclocked model, but the stock-clocked R9 295X2 has an MSRP of $1,499. You can expect the R9 295X2 OC to come in at a premium, especially considering it is the first factory overclocked version that should hit the streets.
I'm excited to see this card come to market and push the boundaries of performance.
In the meantime, Ryan got a bit crazy with two stock R9 295X2 cards in quad crossfire and two power supplies. If you've got a few grand burning a hole in your pocket (or only wish you did), see what such a drool-worthy setup can get you in terms 4K gaming at PC Perspective!

Ryan isn't the only crazy one out there stringing 2 PSUs together to power a pair of AMD's massively powerful 295X2s in CrossFire; the gang at [H]ard|OCP did as well after taking the Mickey with a certain Brian. As with Ryan's experiment they required a second PSU, in this case a 1350W plus an 850W in order to stop the rig from crashing. Their test components also differed somewhat, a Maximus V Extreme instead of a P9X79 Deluxe and slightly different RAM and Win 8.1 installed on their SSD. The other reason to check them out is the Eyefinity 5760 x 1200 tests in addition to the 4K tests.
"Got extra PCIe slots and have no idea what in the world you can do with those? Well if you have $3000 burning a hole in your pocket, wiring in your house that is up to code, a good air conditioning system, and a Type C fire extinguisher that you are not using, AMD's Radeon R9 295X2 QuadFire may be just what the fire marshal ordered."

You need a bit of power for this
PC gamers. We do some dumb shit sometimes. Those on the outside looking in, forced to play on static hardware with fixed image quality and low expandability, turn up their noses and question why we do the things we do. It’s not an unfair reaction, they just don’t know what they are missing out on.
For example, what if you decided to upgrade your graphics hardware to improve performance and allow you to up the image quality on your games to unheard of levels? Rather than using a graphics configuration with performance found in a modern APU you could decide to run not one but FOUR discrete GPUs in a single machine. You could water cool them for optimal temperature and sound levels. This allows you to power not 1920x1080 (or 900p), not 2560x1400 but 4K gaming – 3840x2160.
All for the low, low price of $3000. Well, crap, I guess those console gamers have a right to question the sanity of SOME enthusiasts.
After the release of AMD’s latest flagship graphics card, the Radeon R9 295X2 8GB dual-GPU beast, our mind immediately started to wander to what magic could happen (and what might go wrong) if you combined a pair of them in a single system. Sure, two Hawaii GPUs running in tandem produced the “fastest gaming graphics card you can buy” but surely four GPUs would be even better.
The truth is though, that isn’t always the case. Multi-GPU is hard, just ask AMD or NVIDIA. The software and hardware demands placed on the driver team to coordinate data sharing, timing control, etc. are extremely high even when you are working with just two GPUs in series. Moving to three or four GPUs complicates the story even further and as a result it has been typical for us to note low performance scaling, increased frame time jitter and stutter and sometimes even complete incompatibility.
During our initial briefing covering the Radeon R9 295X2 with AMD there was a system photo that showed a pair of the cards inside a MAINGEAR box. As one of AMD’s biggest system builder partners, MAINGEAR and AMD were clearly insinuating that these configurations would be made available for those with the financial resources to pay for it. Even though we are talking about a very small subset of the PC gaming enthusiast base, these kinds of halo products are what bring PC gamers together to look and drool.
As it happens I was able to get a second R9 295X2 sample in our offices for a couple of quick days of testing.
Working with Kyle and Brent over at HardOCP, we decided to do some hardware sharing in order to give both outlets the ability to judge and measure Quad CrossFire independently. The results are impressive and awe inspiring.
