asus vg248qe lcd panel brands

ASUS VG248QE fast gaming monitor shortens the time it takes for rendered frames to display on the screen. Lower monitor latency gives a gamer the opportunity to improve their in-game response time.

Conventional 60Hz LCDs show extensive motion blur, and can be distracting when playing games with fast movement. The ASUS VG248QE 144Hz fast gaming monitors half the effects of motion blur to deliver a perceivable difference for natural movement and crisp edges on fast paced gaming environments.

As with most ASUS displays, the VG248QE has an ergonomic design, with tilt, swivel, pivot and height adjustment to give users a comfortable viewing experience.

When it comes to design, ASUS always have customers in mind – the ASUS VG248QE features the ASUS-exclusive GamePlus (Patent-pending) hotkey with crosshair (aimpoint) and timer functions. Gamers can select four different aimpoint types to suit the gaming environment; while the latter keeps players aware of the elapsed time in real-time strategy games. These tools allow gamers to practice and improve on their gaming skills.

The VG248QE is compatible with the NVIDIA 3D Vision® 2 kit** through DisplayPort and dual-link DVI, providing support across three Full HD displays for an immersive multi-display 3D gaming experience. DisplayPort, HDMI, and Dual-link DVI-D ports ensure extensive connectivity and compatibility with a variety of multimedia devices including Blu-ray disc players or game consoles; while built-in 2W stereo speakers further add to an immersive home entertainment experience.

The VG248QE is compatible with the NVIDIA 3D Vision® 2 kit**. Through NVIDIA® 3D Vision™ 2 glasses technology, it instantly takes you into another dimension - transforming all your gaming experiences and movies to 3D. Also with the latest NVIDIA® 3D LightBoost™ Technology, user can enjoy twice the brightness of conventional 3D technology in 3D mode with zero increase in total energy consumption.

The ASUS VG248QE monitor is very similar to the BenQ XL2411T in that it uses the same LC panel, supports NVIDIA"s 3D LightBoost, and allows for refresh rates up to 144Hz. It differs from the BenQ XL2411T in that it has a somewhat less stable casing (-), a shiny bezel (-), internal speakers (+), pulse-width-modulated backlight (at a high PWM frequency though) (-), and a much better overdrive control (++). Moreover, the ASUS VG248QE is upgradable with NVIDIA"s GSYNC DIY upgrade kit. This feature is of little use though, as the upgrade kit is not easy to come by – not in Europe anyway. Note that earlier releases of the XL2411T also used PWM backlight (at a low PWM frequency of 180Hz).

When compared to the BenQ XL2411Z, the successor of the XL2411T, the ASUS lacks the flicker-free backlight and, obviously, BenQ"s motion blur reduction feature. However, the ASUS has the advantage of 2D LightBoost being unlockable with ToastyX"s Strobelight tool, which does not work anymore for the Z-versions of BenQ"s XL monitors.

The ASUS VG248QE has a pulse-width-modulated LED backlight, which is usually not seen as a plus, as it can interfere with the monitor"s refresh rate and also causes strobe effects in the presence of eye movements or when motion is being presented. Rather often, manufacturers choose a PWM frequency as low as 180Hz, but ASUS does not only apply a much higher PWM frequency of up to 864Hz (at a 144Hz refresh rate) but also synchronizes the PWM signal to the refresh cycle. The PWM frequency scales with the refresh rate (fPWM=6·frefresh). It should be mentioned that this has been measured with a monitor manufactured in June 2013. Older monitors apparently used a lower PWM frequency of just 360Hz (review on PRAD.de) which might or might not have been scaled with the refresh rate and synchronized to the refresh cycle. CORRECTION: Ahem, 360Hz=6·60Hz, so PRAD.de probably just measured the PWM frequency for a refresh rate of 60Hz, at which it is 360Hz also for monitors manufactured as late as August 2016 (at least).

The ASUS VG248QE allows controlling overdrive through the Trace free parameter which can be set to one of 6 different values (0,20,40,60,80,100). This is obviously better than having only two or three overdrive levels available with BenQ"s XL monitors. Unfortunately, the Trace free parameter is not accessible via DDC/CI (Display Data Channel/Command Interface).

Side note: One might come up with the idea of combining the better overdrive with a hardware-tweaked strobed backlight in order to create something similar to BenQ"s motion blur reduction feature. Such a mode would benefit from an accelerated LC panel update speed which could be achieved to some extent by tweaking the video signal timing (see Monitor timing (tweaking it) in the BenQ XL2411Z review). Unfortunately, the ASUS VG248QE is much more picky when it comes to signal timing and does not allow for stretching the VSync phase much further than normal.

Notice how the integrals (i.e., the pulse energies) of the first high pulse (right panel) and the last high pulse (left panel) are somewhat cut off because the backlight strobe comes too early or too late with respect to the respective pixel settling curves.

There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.TN

The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.8 bits (6 bits + FRC)

Frame Rate Control (FRC) is a method, which allows the pixels to show more color tones. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. For example, by using FRC, a 6-bit display panel is able to show 16.7 millioin colors, which are typical for 8-bit display panels, and not the standard 262200 colors, instead. There are different FRC algorithms.Yes

The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.16777216 colors

The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.W-LED

The Asus VG248QE monitor uses PWM to dim the backlight, so it is not flicker-free but the frequency of the flicker is extremely high and will be unnoticeable by almost anyone, even those sensitive to flicker which is great. However, it was discovered that it flickers at about 6 times the refresh rate (60Hz refresh rate results in 357Hz flicker, 144Hz rate is 857Hz flicker). Changing the backlight doesn"t change the flicker frequency, but rather the screen"s refresh rate changes it, but most people shouldn"t notice this.

A majority of LCD monitors are limited to 60 Hz, which is fine for smooth video and productivity. But when a high-performance rig is pumping out frame rates above that, you want a panel able to keep up.

Even though we"ve tested true120 Hz displays in the past (particularly in conjunction with Nvidia"s 3D Vision technology), Asus is hearing the call from power users for screens with even higher refresh rates. The company has 24- and 27-inch monitors able to operate at up to 144 Hz, and sent us its VG248QE, which has an amazing claimed response time of one millisecond. If you pick the 27" model instead, that increases to a still-amazing 2 ms. Not only is the screen draw time substantially reduced, but input lag (as we discover in the pages to come) is extremely low as well.

Asus achieves this performance with a two-part design approach. First is an overclocked input PCB. While you can modify the input board of any monitor to increase its refresh rate, many screens become unstable right around 72 Hz, though there are a few vendors online selling monitors they"ve tweaked up to higher frequencies. Asus uses its own parts to create a stable platform that can handle the higher rates. The second element is a six-bit TN panel manufactured by AU Optronics. That requires its own bit of explanation.

TN is generally faster at screen draws than IPS because the majority of panels have a six-bit native color depth. This means they are only capable of rendering 262,144 actual colors instead of the 16,777,216 possible from an eight-bit panel. Since the color information coming from the monitor’s processor requires far less bandwidth, the entire signal chain gets a boost in speed.

In order to combat it, TN-based panels use a process called dithering. The more technical term is frame rate control, but the process is the same. Random noise is inserted into the color gradations in order to fuzz-out, for lack of a better term, the color bands. With modern video processing, this technique can be very effective in reducing the effect.

The display in the example to the right can only render red or blue. To make purple, an increasing amount of red and blue noise is inserted into the image until the eye perceives the desired color, even though there is no actual purple in the bottom-right square. Obviously this is a gross over-simplification. The actual technique is far more complex, and the result is practically indistinguishable from an eight-bit panel.

In addition to superlative response and lag specifications, Asus provides a nice package that caters to the enthusiast. Let’s check out what else comes in the VG248QE’s carton, besides blazing speed.
