The ASUS PG191 is yet another monitor on a TN matrix, but this matrix features response time compensation. Moreover, the manufacturer claims it to be one of the fastest matrixes available, with a response time of only 2 milliseconds GtG. As opposed to the Acer AL1916, the viewing angles of the PG191 are declared to be 160 degrees wide, but this doesn’t mean any improvement in the matrix manufacturing technology. It is just a different way of measuring the same angle. The viewing angles of the AL1916 are measured by a contrast drop to 10:1 whereas the viewing angles of the PG191, by a contrast drop to 5:1. It means the PG191 is no competitor to monitors on *VA or S-IPS matrixes in this parameter notwithstanding the high number in its specs.
The PG191 looks like an ASUS monitor indeed. The company pays much attention to the exterior design of its products, and this one features black glossy plastic of the case, touch-sensitive buttons (which are virtually invisible until the monitor is turned on), and an aluminum stand.
The monitor is equipped with a built-in web-camera located above the screen. The camera is set into the case and can turn up and down, but not to the left or right. Its image quality is typical such cameras – just enough for a video conference.
The key feature of this monitor can be found at its back: most other multimedia LCD monitors come with a couple of mediocre speakers whereas the ASUS PG191 offers a full-featured subwoofer fastened on the stand behind the monitor case.
The subwoofer is shaped like a cylinder and is placed on the stand at a distance from the case. This helps suppress its vibration that otherwise would have a negative effect on the monitor’s operation.
The sound system of the PG191 should not be regarded as something exceptional, though. The subwoofer just adds some low frequency to the flat and inexpressive sound of the common tiny speakers hidden behind the monitor’s front panel. I can acknowledge that the PG191 does sound better than other multimedia monitors, yet any standalone desktop speaker system, even a cheap one, will anyway be far better, especially when it comes to reproducing music.
The monitor’s stand is large and heavy, yet doesn’t look bulky thanks to its shape. It is rigid and steady, but its functionality is limited to changing the tilt of the screen. You can replace the stand with a VESA-compatible mount (to hang the monitor on a wall, for example), but it means giving up the monitor’s subwoofer.
Most of the monitor’s connectors are to be found on its back. Here you can find analog and digital inputs, connectors for the audio card’s line output and microphone input, a USB connector for the integrated USB hub and the above-mentioned web-camera, and a subwoofer connector.
