NVIDIA's G-Sync allows video cards to time the refresh rate of monitors. This is an advantage because the GPU knows when a frame is actually ready to be displayed to the user. The initial batch of announcements were each 1080p monitors, which are least likely to dip down into the 30-60Hz gap where G-Sync is noticeable.
Today at Computex, ASUS has announced a 27", 2560x1440, 144Hz G-Sync display. This higher resolution is starting to reach the point where faster graphics cards struggle to maintain 60 FPS. Not only that, but it is one of the first 1440p panels that you can get which supports high (over 100Hz) refresh rates, officially. Others exist, but "rare" is an understatement.
Its response rate is 1ms (GTG) which, unfortunately, suggests a TN panel. This might be a deal-breaker for some, but if you are looking for a G-Sync, 1440p, and high refresh rate panel, then it might be an acceptable compromise.
The ASUS PG278Q is available in Q2, which ASUS seems to define as the beginning of May to the end of July, for $799 USD. Unfortunately for AMD fans, the panel does not seem to support FreeSync, recently added to DisplayPort 1.2a. FreeSync, of course, is the competitor to G-Sync that AMD proposed to the VESA standards body.

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.

The Densest 2.5 Hours Imaginable

After the interest in our overview of the SEIKI 50-in 4K HDTV last April, we got word that SEIKI was making a smaller version of the same television. The SE39UY04 is now available and sells for just under $700 at various online retailers and is surely piquing the interest of many PC users and enthusiasts with the combination of a 3840x2160 resolution and 39-in screen size.
In nearly every way, this 39-in model is identical to the 50-in version with the exception of size and pixel density. Having just recently published a review of the ASUS PQ321Q 4K monitor on PC Perspective I can now report that the move from 60 Hz screens to 30 Hz screens, even at this kind of resolution and screen size, is very apparent.
Below is our initial video unboxing and overview of the new SEIKI SE39UY04. Check it out and leave us any questions or ideas below!

This just in! We have a 4K TV in the PC Perspective Offices!
While we are still working on the ability to test graphics card performance at this resolution with our Frame Rating capture system, we decided to do a live stream earlier today as we unboxed, almost dropped and then eventually configured our new 4K TV.
The TV in question? A brand new SEIKI SE50UY04 50-in 3840x2160 ready display. Haven't heard of it? Neither have we. I picked it up over the weekend from TigerDirect for $1299, though it actually a bit higher now at $1499.
The TV itself is pretty unassuming and other than looking for the 4K label on the box you'd be hard pressed to discern it from other displays. It DID come with a blue, braided UHD-ready HDMI cable, so there's that.
One point worth noting is that the stand on the TV is pretty flimsy; there was definitely wobble after installation and setup.
Connecting the TV to our test system was pretty easy - only a single HDMI cable was required and the GeForce GTX 680s in SLI we happened to have on our test bed recognized it as a 3840x2160 capable display. Keep in mind that you are limited to a refresh rate of 30 Hz though due to current limitations of HDMI 1.4. The desktop was clear and sharper and if you like screen real estate...this has it.
The first thing we wanted to try was some 4K video playback and we tried YouTube videos, some downloaded clips we found scattered across the Internet and a couple of specific examples I had been saving. Isn't that puppy cute? It was by far the best picture I had seen on a TV that close up - no other way to say it.
We did have issues with video playback in some cases due to high bit rates. In one case we had a YUV uncompressed file that was hitting our SSD so hard on read speeds that we saw choppiness. H.265 save us!
And of course we demoed some games as well - Battlefield 3, Crysis 3, Skyrim and Tomb Raider. Each was able to run at 3840x2160 without any complaints or INI hacks. They all looked BEAUTIFUL when in a still position but we did notice some flickering on the TV that might be the result of the 120 Hz interpolation and possibly the "dynamic luminance control" feature that SEIKI has.
We'll definitely test some more on this in the coming days to see if we can find a solution as I know many PC gamers are going to be excited about the possibility of using this as a gaming display! We are working on a collection of benchmarks on some of the higher end graphics solutions like the GeForce TITAN, GTX 680s, HD 7990 and HD 7970s!
