Here comes the announcement of the first Nvidia G-SYNC enabled monitor at CES 2014 fromm ASUS – the ASUS ROG Swift PG278Q. The monitor supports WQHD 2560×1440 resolution and ASUS says it is a 120+ Hz display, so this is also the first monitor to officially support 120Hz refresh rate with a resolution over 1920×1080. What is not so good news for some people is the that the display probably uses a TN panel, something that is suggested by the announced 1ms response time. And the other not so good news is that there is not a single mention of 3D Vision support, so apparently this display from ASUS is not 3D-capable, meaning we are still don’t have a 3D Vision monitor with a resolution higher than 1080p.
The ROG SWIFT PG278Q is also the world’s first WQHD monitor powered by NVIDIA G-SYNC technology. NVIDIA G-SYNC, a breakthrough in display technology, synchronizes the display’s refresh rates to the GPU. The ROG SWIFT PG278Q eliminates screen tearing, minimizes stutter and input lag to deliver the smoothest gaming experience possible. With G-SYNC technology objects look sharper and more vibrant, while gameplay is more fluid and responsive.
ASUS ROG SWIFT PG278Q Specifications:
- Display: 27-inch WQHD 2560×1440 (16:9)
- Narrow 6mm bezel designed for multi-monitor setups
- Pixel Pitch: 0.233mm
- Brightness: 350cd/m2
- Display Colors: 16.7M
- Refresh Rate: Over 120 Hz
- Response Time: 1ms (GTG)
- Connectivity: 1x DisplayPort 1.2, 2x USB 3.0 ports
- Stand Adjustments: tilt (+20° ~ -5°), swivel (+60° ~ -60°), pivot (90° clockwise), height adjustment (0 ~ 120mm)
- VESA-wall mountable (100 × 100mm)
- Special ASUS Features: GamePlus and 5-way joystick OSD navigation
According to ASUS the ROG SWIFT PG278Q monitor availability is expected at the beginning Q2 this year for the Asian Pacific, European and North America markets. So we can expect to see this monitor available as early April this year with an expected price of $799 USD. As a comparison you might be able to get earlier an ASUS VG248QE monitor modified to support Nvidia’s G-SYNC technology for about $500 USD, however this is a 24-inch model with 1920×1080 resolution and the ASUS ROG SWIFT PG278Q monitor is 27-inch and with 2560×1440 resolution. It would’ve been nice if this was also announced as a 3D Vision monitor, but there is still some time left until it’s release, so it could get certified by the time for the official release on the market as it has the required features to support stereoscopic 3D as well.

Soon after the announcement of the new 27-inch BenQ XL2720Z 3D-capable monitor, the company has just announced two new 24-inch 3D-capable displays that essentially bring the new features of the larger model to the smaller 24-inch ones. The new BenQ XL2411Z and BenQ XL2420Z will probably replace the older XL2411T and XL2420T/TX series, but the not so good news is that these two new models expected early next year will not feature support for the new Nvidia G-Sync technology. Nvidia has promised us the G-Sync DIY upgrade modules before the end of the year, but we are still not seeing these available, and availability of models with G-Sync support built-in early next year, but it seems things may get delayed a bit. BenQ XL2411Z and XL2420Z are suppose to be available in early 2014 and probably not too long after their release on the market BenQ may also announce new series that are supposed to provide G-Sync support as well as the company is an Nvidia launch partner for the G-Sync technology.
Enough with G-Sync for now, the BenQ XL2720Z and the new smaller BenQ XL2420Z and XL2411Z monitors that will feature 3D Vision support with an external 3D Vision kit (including IR emitter as it is not built in) as well as 3D LightBoost technology. However, apart from the 3D LightBoost support (strobing backlight) these display feature a new Motion Blur Reduction technology developer by BenQ that is supposed to work in a similar way as the 3D Lightboost, however BenQ’s solution will be video card type independent and you will not need to “hack” it to work in 2D mode as well. Other interesting things about the new BenQ Z-series is a the addition of Low Blue Light mode that allows gamers to adjust the blue light levels of the monitor – what is considered to be the major cause of eyestrain when using computers for long periods of time. Another new feature introduced a these monitors is the Gaming-comfort Flicker-free technology that is supposed to eliminate noticeable flickering of the backlight when you lower the brightness level of the monitor (no PWM dimming of the backlight).

ShadowPlay is an extra functionality that allows the owners of compatible Nvidia Kepler-based graphic cards to take advantage of the built-in H.264 encoder to record gameplay video with hardware acceleration directly into small in size MP4 video files. ShadowPlay is a part of the GeForce Experience software that now comes as a part of the Nvidia video drivers, and although it is still in Beta stage it looks quite promising. And while ShadowPlay was introduced last month with the release of the GeForce Experience 1.7 software I still haven’t been able to try the software, but now I can and since Nvidia just released a new GeForce 331.82 WHQL video driver that comes with an update to GeForce Experience 1.7.1 it is time to try out this feature. Aside from the new version of the Geforce Experience software the new video drivers also come with a 3D Vision profile for the game Assassin’s Creed IV: Black Flag and it is rated as “Good” for playing in stereo 3D with 3D Vision setups.
Looking at the ShadowPlay interface you can easily see that it is designed with the normal users in mind, by providing you with a simple and easy to understand clickable buttons for configurations. But more advanced users like me will miss some simple things like an option to remap the default ALT + F9 key combination for manual start/stop of the recording for example or an option to control the recording resolution or framerate and so on. Hopefully Nvidia is going to add some more extra controls for the more advanced users as well with upcoming updates.
What I still haven’t mentioned regarding ShadowPlay is if ti supports recording of stereoscopic 3D gameplay videos as this is something that people playing on 3D Vision setups actually do need and can appreciate. Officially before the release of the ShadowPlay feature Nvidia did not say that it will have stereo 3D support, and now that the software is available still no official 3D Vision support. The good news is that ShadowPlay can actually already record stereo 3D gameplay videos, but with one important thing to note – the 3D video you get is also in 1920×1080 resolution meaning that it is essentially recorded in Half Side by Side format (half horizontal resolution per eye). Not that this is a bad thing compatibility wise, but it would’ve been nice if the user can select between Half SbS mode and Full Side by Side (maybe limitation of the hardware H.264 encoder?). FRAPS for example as the only other gameplay video capture software with stereoscopic 3D video recording support does only output in Full Side by Side format, but the major problem with FRAPS is that the video output is hardly compressed and recording 3D video does result in a lot of gigabytes per minute of recording.
So to summarize things, the ShadowPlay feature is apparently intended for gameplay video recording of 2D gameplay, though it also supports 3D gameplay video recording in Half Side by Side format meaning that the two views are squashed in a single Full HD frame and FRAPS on the other hand produces Full Side by Side output when recording stereoscopic 3D video. ShadowPlay does output small H.264 compressed video files that are ready for online sharing, unlike FRAPS that produces multi-gigabyte files for each minute of recorded footage and recording 3D makes the files even bigger, s you need to re-compress them before uploading and sharing them. The performance drop when using ShadowPlay should be significantly less, because the hardware H.264 encoder of the video card is used to compress and output small files, unlike FRAPS where the CPU handles the minimal compression applied and the HDD/SSD needs to handle the serious load caused by the large amounts of data written each second, so the performance drop is more significant. FRAPS has more features and more controls for the more advanced users while maintaining ease of use by the normal user as compared to the way too user friendly and somewhat lacking features interface of the ShadowPlay.
And now for some tests of ShadowPlay and a comparison with FRAPS when both are set to record video at 1080p 60 fps in various conditions in the game Battlefield 4. The game was chosen because it can be quite heavy even for the fastest GPUs when you up the graphical settings to the maximum as in the current case – Ultra Quality with 4xMSAA with a GeForce GTX 780 Ti video card. Battlefield 4 is not recommended by Nvidia to be played in stereoscopic 3D mode with 3D Vision, but it is still Ok for benchmarks and recording, so take a look at the interesting results below.
- 96 fps in 2D mode playing with 3D Vision disabled in the Control Panel
- 90 fps in 2D mode with ShadowPlay recording and 3D Vision disabled in the Control Panel
- 51 fps in 2D mode recording video with FRAPS and 3D Vision disabled in the Control Panel
- 69 fps in 2D mode playing with 3D Vision enabled in the Control Panel, but turned off
- 38 fps in stereo 3D mode with 3D Vision enabled and running
- 36 fps in stereo 3D mode with ShadowPlay recording video
- 25 fps in stereo 3D mode with FRPAS recording video on an SSD drive
- FRAPS 1 min 2D – 2.8 GB
- FRAPS 1 min 3D – 4.4 GB
- ShadowPlay 1 min high 2D/3D ~ 112 MB (varies based on the content)
As you can see from the results above, by using ShadowPlay you get to loose much less FPS compared to when recording video with FRAPS and also the output video’s file size can be significantly less. Aside from that you can probably notice that Battlefield 4 does not handle that well performance wise with 3D Vision enabled, even when it is not active you still get significant performance drop as compared to normal 2D mode and that is probably half the reason why the game has a Not Recommended rating for 3D Vision and the other half is the visual issues when rendering in stereo 3D mode.
And one interesting observation that I made while testing was the fact that as long as 3D Vision is activated from the Nvidia Control Panel then when you record gameplay video with ShadowPlay you are getting a stereo 3D recording in Half Side by Side format, regardless if you have pressed CTRL+T to enable or disable the display of 3D data on the screen. So you need to be careful when you want to play and record gameplay video in 2D mode you will have to disable the 3D Vision stereoscopic 3D support form the Control Panel before running the game and for recording stereo 3D gameplay video the good thing is that you may not actually play in stereo 3D mode while recording in it.
