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!
Our 4K Testing Methods
You may have recently seen a story and video on PC Perspective about a new TV that made its way into the office. Of particular interest is the fact that the SEIKI SE50UY04 50-in TV is a 4K television; it has a native resolution of 3840x2160. For those that are unfamiliar with the new upcoming TV and display standards, 3840x2160 is exactly four times the resolution of current 1080p TVs and displays. Oh, and this TV only cost us $1300.
In that short preview we validated that both NVIDIA and AMD current generation graphics cards support output to this TV at 3840x2160 using an HDMI cable. You might be surprised to find that HDMI 1.4 can support 4K resolutions, but it can do so only at 30 Hz (60 Hz 4K TVs won't be available until 2014 most likely), half the refresh rate of most TVs and monitors at 60 Hz. That doesn't mean we are limited to 30 FPS of performance though, far from it. As you'll see in our testing on the coming pages we were able to push out much higher frame rates using some very high end graphics solutions.
I should point out that I am not a TV reviewer and I don't claim to be one, so I'll leave the technical merits of the monitor itself to others. Instead I will only report on my experiences with it while using Windows and playing games - it's pretty freaking awesome. The only downside I have found in my time with the TV as a gaming monitor thus far is with the 30 Hz refresh rate and Vsync disabled situations. Because you are seeing fewer screen refreshes over the same amount of time than you would with a 60 Hz panel, all else being equal, you are getting twice as many "frames" of the game being pushed to the monitor each refresh cycle. This means that the horizontal tearing associated with Vsync will likely be more apparent than it would otherwise.
I would likely recommend enabling Vsync for a tear-free experience on this TV once you are happy with performance levels, but obviously for our testing we wanted to keep it off to gauge performance of these graphics cards.

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!
