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!

Specifications and Overview

Talk to most PC enthusiasts today, be they gamers or developers, and ask them what technology they are most interested in for the next year or so and you will most likely hear about 4K somewhere in the discussion.  While the world of consumer electronics and HDTV has been stuck in the rut of 1080p for quite some time now, computers, smartphones and tablets are racing in the direction of higher resolutions and higher pixel densities.  4K is a developing standard that pushes screen resolutions to 4K x 2K pixels and if you remove the competing options discussion (3840x2160 versus 4096x2160 are the most prominent) this move is all good news for the industry.

I first dove into the area of 4K displays when I purchased the SEIKI SE50UY04 50-in 4K TV in April for $1300 when it popped up online.  The TV showed up days later and we did an unboxing and preview of the experience and I was blown away by the quality difference by moving to a 3840x2160 screen, even with other caveats to be had.  It was a 30 Hz panel, half a typical LCD computer display today, it had limited functionality and it honestly wasn't the best quality TV I had ever used.  But it was 4K, it was inexpensive and it was available. 

It was hard to beat at the time but the biggest drawback was the lack of 60 Hz support, the ability for the screen to truly push 60 frames per second to the panel.  This caused some less than desirable results with Windows usage and even in gaming where visual tearing was more prominent when Vsync was disabled.  But a strength of this design was that it only required a single HDMI connection and would work with basically any current graphics systems.  I did some Frame Rating game performance testing at 4K and found that GPU horsepower was definitely a limiting factor.

Today I follow up our initial unboxing and preview of the ASUS PQ321Q 4K monitor with a more thorough review and summary of our usage results.  There is quite a bit that differs between our experience with the SEIKI and the ASUS panels and it is more than just the screen sizes.

NVIDIA Releases 326.19 Beta Driver, Adds Support for 4K Tiled Displays!

It would appear that NVIDIA was paying attention to our recent live stream where we unboxed and setup our new ASUS PQ321Q 4K 3840x2160 monitor.  During our setup on the AMD and NVIDIA based test beds I noticed (and the viewers saw) some less than desirable results during initial configuration.  The driver support was pretty clunky, we had issues with reliability of booting and switching between SST and MST (single and multi stream transport) modes caused the card some issue as well.

Today NVIDIA released a new R326 driver, 326.19 beta, that improves performance in a couple of games but more importantly, adds support for "tiled 4K displays."  If you don't know what that means, you aren't alone.  A tiled display is one that is powered by multiple heads and essentially acts as multiple screens in a single housing.  The ASUS PQ321Q monitor that we have in house, and the Sharp PN-K321, are tiled displays that use DisplayPort 1.2 MST technology to run at 3840x2160 @ 60 Hz. 

It is great to see NVIDIA reacting quickly to new technologies and to our issues from just under a week gone by.  If you have either of these displays, be sure to give the new driver a shot and let me know your results!

Some more 4K love!

This morning Fedex dropped off a new product at our offices, one that I was very eagerly awaiting: the ASUS PQ321Q 31.5-in 4K 60 Hz monitor!

While we are far from ready to post a full review of the display and have lots of more game testing to get to, we did host a live stream for the unboxing and initial testing of the PQ321Q that I think is worth sharing.

In this video we do a walk around the $3500 4K display, hook it up to both NVIDIA and AMD test bed at 60 Hz and then proceed to install 3-Way SLI Titans to see how it games!  Enjoy this quick preview before our full review of the ASUS PQ321Q.

UPDATE: This display is now available for purchase if you want to shell out the $3500!

ASUS launches PQ321 monitor with 3840 x 2160 IGZO display

While they did fail to provide us with a price we do know that some time this month ASUS will be offering a 4K display for sale in North America, so you may not have to special order one from overseas anymore.  Of course as the two models are 39" and 31.5" you can expect a premium price as not only is 4K relatively new, the sizes of these monitors are also very new to the market ... at least for PCs.  The extra size does bring the pixel density down to 140 ppi but you will still have beautiful picture quality.

PQ321Q_Front.jpg

Taipei, Taiwan (30 May, 2013) — ASUS today announced the PQ321 True 4K UHD Monitor, a desktop display with a stunning Ultra HD 3840 x 2160 resolution that’s equivalent to four Full HD displays stacked side-by-side. The PQ321 has a 31.5-inch LED-backlit 4K Ultra HD display (140 pixels-per-inch) with 16:9 aspect ratio, and supports 10-bit RGB ‘deep color’ for vibrant images with more natural transitions between hues.

Cutting-edge IGZO panel technology
The ASUS PQ321 True 4K UHD Monitor uses cutting-edge Indium Gallium Zinc Oxide (IGZO) rather than traditional amorphous silicon for the active layer of its LCD panel. IGZO panels support much smaller transistors than amorphous silicon, which in turn gives much smaller pixels and the 3840 x 2160 resolution of the PQ321 is four times that of a 1920 x 1080 Full HD display.

176-degree wide viewing angles on both vertical and horizontal planes minimize onscreen color shift, while the 350cd/m² brightness rating and 8ms gray-to-gray response time ensure smooth, bright, and vibrant moving visuals. IGZO technology also gives reduced energy consumption compared to amorphous silicon and reduces bulk — at 35mm at its thickest point, the PQ321 is the thinnest 4K UHD monitor available today.

Comprehensive video inputs for UHD content
The ASUS PQ321 True 4K UHD Monitor features DisplayPort and US models offer dual-HDMI ports inputs with Picture-by-Picture support. Built-in 2W stereo speakers remove the need for additional desktop clutter and, in addition to being wall-mountable, the monitor stand offers full height, swivel, and tilt adjustment.

AVAILABILITY & PRICING
ASUS will be exhibiting the 39-inch and 31.5-inch True 4K UHD Monitor models at Computex 2013 in Taipei. The ASUS PQ321 True 4K UHD Monitor will be available in North America in the end of June.

Computex, the second largest expo for computer hardware, is less than a week away but its influence tends to bleed over a little bit. And, since we know our readers love 4K displays, we thought we might pass along a leak we found for a new ASUS monitor.

And yes, that is a 32"

The Asus PQ321 is both a relatively easy-to-remember model number and a 31.5" computer monitor with 4K2K resolution. Connect it to your computer with DisplayPort or, for at least some US models, dual HDMI to have the same resolution as IMAX Digital as well as have a legitimate reason to pick up multiple GeForce Titan graphics cards.

The raw specifications are:

  • 31.5 inch display size (16:9 aspect ratio)
  • Indium Gallium Zinc Oxide (IGZO) panel, LED backlit
  • 3840x2160 resolution (140ppi)
  • 1.07 billion colors (10-bit RGB)
  • 176 / 176 (H / V) degree viewing angle
  • 350 cd/m2 brightness
  • 8ms (gtg) response time
  • Color temperature and gamma adjustments
  • I/O: DisplayPort, 2x HDMI ("optional"), RS-232C, 3.5mm audio in and out
  • 2W stereo speakers
  • Tilt, swivel, height adjustments; VESA mount (no landscape/portrait pivot)
  • 750mm x 489mm x 256mm with stand, 13kg net weight
  • Comes with DisplayPort 1.2 cable and an RS-232C conversion cable (???)

Looking at these specifications, it certainly feels like an IPS-equivalent technology with some very telltale characteristics: the relatively slow response time for seemingly no reason, the 1.07 billion colors, the very wide viewing angle, and the relatively high pixel density per inch. This prompted me to look over at the ASUS website for some tea leaf reading. It looks as though all P- or M-series monitors utilize some form of IPS technology, the M-series referring to thin-bezel options and the P-series to relatively image quality-focused products.

So as best as I can tell, the PQ321 is a 31.5" 4K IPS monitor.

ASUS is expected to display this at Computex 2013 in Taipei along with a 39" 4K monitor. No word on pricing or availability, at least not yet.
