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.

Hardware/Software Picks of the Week:
Ever since CES we have been expecting an onslaught of 4K monitors to make their way to the market. Today Amazon.com listed the Samsung U28D590D for pre-order for the price of just $699. This is a 28-in display with a 3840x2160 resolution and support for 60 Hz refresh rates courtesy of the DisplayPort 1.2 connection.
That's a hell of a deal for a 4K monitor, especially one capable of 60 Hz (likely through MST)! Worth noting is that the monitor is a TN panel so picture quality won't be as good as the IPS options still selling for over $2500, like the ASUS PQ321Q we reviewed previously.
The panel has a pair of HDMI inputs but both are listed as only supporting 30 Hz 3840x2160 resolutions without any mention of using them both simultaneously.
You can find the full specifications list on Samsung's website, and we are working to get a sample in for testing in the next two weeks!

Just before CES Allyn showed you the process of modifying the ASUS VG248QE to support NVIDIA G-Sync variable refresh rate technology. It wasn't the easiest mod we have ever done but even users without a lot of skill will be able to accomplish it.
But at the NVIDIA booth at CES this year the company was truly showing off G-Sync technology to its fullest capability. By taking the 3840x2160 ASUS PQ321Q monitor and modifying it with the same G-Sync module technology we were able to see variable refresh rate support in 4K glory.
Obviously you can't see much from the photo above about the smoothness of the animation, but I can assure you that in person this looks incredible. In fact, 4K might be the perfect resolution for G-Sync to shine as running games at that high of a resolution will definitely bring your system to its knees, dipping below that magical 60 Hz / FPS rate. But when it does with this modified panel, you'll still get smooth game play and a a tear-free visual experience.
The mod is actually using the same DIY kit that Allyn used in his story though it likely has a firmware update for compatibility. Even with the interesting debate from AMD about the support for VRR in the upcoming DisplayPort 1.3 standard, it's impossible to not see the ASUS PQ321Q in 4K with G-Sync and instantly fall in love with PCs again.
Sorry - there are no plans to offer this upgrade kit for ASUS PQ321Q owners!

CES 2014: Lenovo Convertables, Tablets, and Laptops (Part 2) Y40 & Y50 Touch (with optional 4K), Z40 & Z50

Tagged: Lenovo, GeForce 800M, CES 2014, CES, 4k
For the lover of a more conventional clamshell laptop, Lenovo has four models announced at CES. They do not need a special hinge to avoid the ho-hum. Some of these models have options for GeForce 800-series mobile and Radeon M200-series graphics. Some have options of 802.11ac (and others have it standard). One of the four even includes an option for a 4K panel.
Did I get your attention? Read on.
The Lenovo Y40 and Y50 are their gaming class notebooks with relatively high-performance components. The aesthetic is sort-of flat edges and bevels which looks pretty crisp. The dimensions and weight "start at" under an inch thick and 5.3lbs. Options will be available up to 16 GB of RAM and a 1TB hybrid hard drive with 8 GB of SSD caching. It also appears as if 802.11ac wireless comes standard. You have a choice between 14-inch and 15.6-inch Full HD screens or, for the Y50, you can bump the resolution up to 3840x2160 for some mobile 4K.
The Y50 can be powered by as much as an Intel Core i7-4702HQ processor and an NVIDIA GTX 860M 2GB GPU. This graphics solution is currently unannounced but rumors (just rumors) claim it will have about 1.4 TeraFLOPs of performance from 960 shading units. This puts it a little bit behind the Xbox One in terms of peak shader performance however it is also laptop graphics. If the rumors hold true it should be just slightly behind a GeForce 650 Ti. Perhaps we will learn more as CES continues.
Prices start at around $500.
The Lenovo Z40 and Z50, on the other hand, are their more mainstream laptops. Still, they are capable of upgrades up to an Intel Core i7 with GeForce 800-series graphics. They can include up to 16 GB of RAM and up to a 1TB HDD (with extra options for 8GB SSD caching). The laptop comes default with 802.11 b/g/n but can be upgraded to 802.11ac if desired. They come standard with a 1080p touchscreen display.
More interestingly, prices start at just under $400 (although clearly with less RAM, CPU, and GPU than the up to listings). Lenovo claims you can have "up to Windows 8.1" which makes me wonder if Windows 7 options will be available. That could be interesting if true.
