The PA238QR is the entry model of the Asus top of the line professional art panels. The panel is a standard wide screen FullHD which is industry standard.


The ProArt series is designed for digital photography, cinematography and processional graphic arts. Its also fast enough for games. This line is the flagship for Asus.

The PA238QR features true 8-bit RGB while the more expensive PA238Q features 10-bit RGB color. The top model is the PA248Q which features 12-bit color RGB. Typically TN panels use 6-bit color and dithering.

The GTX 260 has a pair of DVI ports on it which means the PA238QR is the perfect choice. DVI is designed for 8-bit color which matches the panel natively. DisplayPort can support 10-bit color but such panels are far from mainstream. Deep color 10-bit panels start at $1000.

The supplied DVI cable does not work as it is only Single Link DVI-D which is not adequate. Our GTX-260 has a pair of Dual Link DVI-D connector which have adequate bandwidth for 2560×1600.

We have a DVI-to-HDMI dongle for the GTX 260 so its possible to use HDMI if desired. The GTX 260 needs a cable feed from the S/PDIF header to be able to provide sound, but newer video cards now have integrated audio.

The EVGA GTX 680 has DVI, HDMI and DisplayPort so the PA238QR is suitable for use well into the future. FullHD is the standard looking forward, 4K UHDTV is simply a doubling of resolution so HDTV will continue for a ling time to come. The first 4K UHDTV from LG entered the market in February 2013 for $5,500 suggesting it may be more than a decade before it reaches the mainstream.

The PA238R3 has a medium-bezel design with a basic black finish. The panel supports full rotation to portrait mode which is helpful for many purposes.

Desktop publishing is a frequent user of portrait mode where a whole page can be displayed making object placement much easier.

Email users can see far more work when using most clients in portrait mode.

The stand is fully adjustable making it far easier to use. Most panels only give limited swivel while the PA238QR offers height adjustment

There are 2 USB 2.0 ports on the rear for the keyboard and mouse and 2 more on the side for USB sticks. Integrated USB is now largely mainstream.

Mainstream panels offer VGA and DVI but the PA238QR adds HDMI and DisplayPort to make it as widely compatible as possible. Recent high-end video cards now are shipping with DisplayPort which is slowly entering the mainstream. HDMI is widely used with television and cable TV boxes.

The panel includes VGA and DVI cables which are the most widely used. It also includes a power cable and USB cable for the integrated hub.

The PA238QR has a novel human sensor to detect if a person is present and it automatically goes into standby when nobody is present. This can be disabled if desired.

The panel also features easy to identify panel buttons to select features.

Playing games with it did not present any serious problems.  As expected some older games look stretched due to the limitations of the engine. Modern games are designed for 1920×1080 so we expect the PA238QR to be ideal for games, TV and BD. The panel can do a reasonable job emulating a CRT during the boot into Windows. Even the BIOS is shown full screen fine with no problems. Works fine with our KVM switch as well using the VGA connector.

Better IPS panels feature an overdrive to improve the response time. It works by increasing the voltage applied to the liquid crystal. The PA238QR has an option to adjust the overdrive as desired however we found no problems with lag using the defaults. Overdrive is still not widely seen with IPS panels generally.

The viewing angle of IPS panels is excellent which makes them suitable for a wide range of purposes. Large display monitors would be a big beneficiary of IPS.

This is a new panel for 2012 so we are expecting longer life. LED is a mature technology and it should be stable for decades.


This monitor has much better color compared to our Acer AL1916 and OM19WD. The PA238QR offers significantly better color and contrast.

The PA238QR also has a higher pixel density. Windows is designed to work with varying pixel density panels so the desktop works exactly the same. Future desktop panels will likely see higher pixel density over time.

The PA238QR features full sRGB color space compatibility. TN monitors cannot come close to this at all. Games, cameras, TV and BD are all designed with sRGB color space as the standard. sRGB is still far from the mainstream but prices are coming down.

Television shows, PC games and DVD movies all looked much better. BD runs at 1080p so image quality is far better than DVD.


We tested the panel with our Motorola DCX3200-M digital cable box with the HDMI input. The panel displayed 1080i channels fine. Picture quality varies widely depending on the channel.


We find that LCD panels are generally cleaner than the older CRT screens. This can be explained by the use of high voltage in the CRT that can create static charge that cause dust to cling to the surface. The LCD does not use high voltage so dust is not attracted to the screen.
