New LightBoost monitor: AOC g2460Pqu

pcmonitors.info confirmed that the 144Hz AOC g2460Pqu supports 3D Vision 2, which automatically means LightBoost support!  This is an unadvertised feature, but is good news!

2560x1440p LCD monitors overclockable to 120 Hz

There are several 27″ high resolution 2560×1440 computer monitors that are “overclockable” to 120 Hz using a high quality IPS (or PLS) panel, including the Catleap 2B and the Overlord Tempest X270OC.  These are not as clear motion as LightBoost (CRT clarity), but have much less motion blur than 60 Hz (photo comparison of motion blur).

These displays overclock using refresh-rate overclocking methods such as ToastyX Custom Resolution Utility (harder), or those found in EVGA Geforce Titan or GTX 680 (easier, shown in dialog below):

Recently, HardForum users have found that the much cheaper QNIX Q2710 Evolution 2 monitor (1440p) overclocks easily to 100-120 Hz!  The best thing is that these high resolution 27″ 2560×1440 displays cost a mere $340 on Amazon!

4K TV for only $1500; can do 1920×1080 @ 120Hz native!

The brand new SEIKI brand 4K HDTV has arrived with 3840×2160 resolution for only $1500 on TigerDirect.  This is an incredibly low introductory price for 4K HDTV.  A big bonus is that it also supports a native 120Hz refresh rate at 1080p!

A user on HardForum has discovered that the SEIKI 4K HDTV can run 1920×1080 successfully at a native 120Hz refresh rate!  Confirmed by Refresh Rate Multitool. It also appears to run at higher refresh rates as shown below, though 120 Hz is the maximum supported rate with no frame skipping.

Ars Technica mentions LightBoost

There is a great Ars Technica System Guide that mentions LightBoost’s motion blur elimination benefits (page 3).  Check it out!

Teardown: LightBoost Reverse Engineering for Scientific Use

Marc Repnow (StrobeMaster), a researcher who maintains http://display-corner.epfl.ch, did a BENQ XL2411T tear-down and a BENQ XL2420T tear-down. He discovered how to modify LightBoost electronics, for use for scientific tachistoscopic applications.  Apparently, XL2411T’s can be used as an inexpensive scientific tachistoscope, thanks to LightBoost!

For enthusiast gamers, the discovery of LightBoost trigger electronics also provide a means of hacking for a brighter LightBoost picture (bigger boost pulse), shorter strobe flashes (for clearer fast motion), and better color (via adding a wide-gamut edgelight).

Overclocked Quad Titan SLI on Three 120Hz Monitors

The world’s most powerful single-GPU graphics cards, nVidia GeForce Titan, cost over $1000 each.  But what happens if you buy FOUR Titans, and overclock all of them with water-cooling on triple-LightBoost setup?  Crysis 3 running at 120fps @ 120Hz on three ASUS VG248QE LightBoost monitors in surround mode!

See Vega’s recent post in the HardForum thread.  At Blur Busters, we think nVidia needs to sponsor an all-expenses paid trip for this rig to a gaming convention (E3, GDC, QuakeCon).  It would sell enough GeForce Titan‘s and LightBoost monitors to more than cover the cost of such a trip!  CRT-quality motion on triple monitor surround.

EDIT: 3DMark11 score of 33189 by userid CallsignVega! The world’s fastest 3DMark11 score for a true 24/7 gaming system; not a liquid nitrogen cooled system!

BENQ XL2720T First Impressions on HardForum

A user has posted first impressions of BENQ XL2720T on HardForum. Initial impressions are positive for its LightBoost motion blur elimination; and preferring this over IPS LCD.

BENQ XL2720T, a 120Hz 27″ LightBoost LCD, is also now available from Amazon.com.

NewEgg.com Video Mentions LightBoost 2D Zero Motion Blur

NewEgg and ASUS are now both officially aware of the LightBoost tweak for eliminating motion blur on LCD displays.  LightBoost recently became a very popular feature driving sales of the VG248QE monitor.  It is mentioned beginning at 5:18 in this YouTube:

New customer reviews for ASUS VG248QE on both Amazon and NewEgg now mention the 2D motion blur eliminating feature of LightBoost more often than its original intended 3D Vision purpose.  Even googling “LightBoost” now returns more highly-ranked results in 2D motion blur elimination, than for 3D Vision!

nVidia needs to re-brand LightBoost as also being a marketing feature for 2D, and make it an officially easily-enabled feature; because it beginning to drive some sales of GeForce GTX 680′s and Titans in many forums threads.

Article on Why Some OLED’s Have Motion Blur

OLED has been regarded as a Holy Grail for motion blur. Unfortunately, the portable Playstation Vita has lots of motion blur during fast scrolling animations. This is due to sample-and-hold. The PS Vita OLED is bottlenecked by this issue. Some newer OLED’s eliminate motion blur, but not all do. Even instant pixel response (0 ms) can have lots of motion blur because of sample-and-hold. Frames continuously shines for a whole refresh. When tracking moving objects, your eyes are in different positions throughout a whole refresh; this causes the frame to be blurred across your retinas:

The Amazing Surround CRT-Equivalent Setup

Vega of HardForum set up an amazing surround CRT-quality setup with three ASUS VG248QE and GeForce Titans’s (plus the LightBoost tweak to eliminate motion blur).

1174.,1,0,0,331,256,369,1,0,33,37,1,0,100,0,1943,1935,2144,1283603

This was made possible via a new method of enabling LightBoost (See comments!).  Although TN panels are not good for portrait usage due to viewing angles, fast panning motions remains as perfectly clear (CRT-quality) as stationary images. The CRT-like “smooth as butter” motion apparently outweighed TN panel deficiencies for some users!

Try that with CRT-sized bezels!
