ASUS VG278H 27"
+ Better-than-average LightBoost color
+ Easier to enable LightBoost, due to builtin emitter
+ Can exceeds 700:1 contrast ratio in LightBoost (when recalibrated after setting Contrast OSD=75% or 80%)
- LightBoost artifacting (corsstalk) becomes bad if you raise Contrast to 90% instead of 65%. (nearly invisible ghosting at 65% though)
ASUS VG278HE 27"
- This may not be consistent on all VG278HE's but some of them reportedly had a more amplified LCD inversion artifact (pixel checkerboard artifact similiar to this
), and hazmatm compared VG278H vs VG278HE
and 3 others concurred.
- This is the display reviewed by TFTCentral's Motion Blur Reduction Backlights
ASUS VG248QE 24"
+ Clearer than average LightBoost (lack of crosstalk, lack of faint ghost double-image aftifact) -- no ghosting, no overdrive artifacts, no trailing, nothing at all
+ Best CRT effect according to many (e.g. Vega)
- Poor color. Lower contrast ratio, about 500:1 (reportedly as low as 250:1 with buggy new 320.18+ drivers)
- Occasionally a very faint scanlines effect at the upper-right corner (some samples)
BENQ XL2411T 24"
... Similiar to VG248QE. It uses the same panel as VG248QE.
BENQ XL2420T 24"
+ Very good color for a LightBoost monitor.
- Poor LightBoost trailing artifacts; I've heard a few reports of LCD inversion artifacts (pixel checkerboard artifact, similiar to this
). This is a different/older panel than the XL2411T
BENQ XL2720T 27"
+ Very good color for a LightBoost monitor with newest drivers (320.18+)
+ Reportedly can approach nearly 1000:1 contrast ratio in LightBoost
- Poor color with older drivers
- Slight dark ghosting effect during LightBoost, but not too strong
Some monitor samples can unexpectedly have worse attributes (e.g. more LCD inversion artifact -- checkerboard artifact -- than others). For example, while my XL2411T does not have a noticeable LightBoost checkerboard artifact, one person reported theirs had a noticeable version of this artifact. Eventually someone needs to obtain all LightBoost monitors and execute the Great LightBoost Comparison Test. Also, I am creating a new LightBoost FAQ page on Blur Busters (e.g. answers common LightBoost questions with known answers), as a supplement, it should be published within the next two weeks.
Also within the same LightBoost monitor, via monitor menus:
- For a brighter image, increase LightBoost %
- For a dimmer image (but clearer motion), decrease LightBoost %
- For less checkerboard artifact, decrease Contrast %
- For less LightBoost trailing artifacts, decrease Contrast % on monitor to 65%
- For less gamma bleaching effect, decrease Contrast % on monitor to 65%
- For maximum color gamut (when recalibrating with a Spyder4 or i1 Pro), increase Contrast % to 90% before beginning colorimeter calibration. Better colors and contrast will occur, but you will get somewhat worse LightBoost trailing artifacts. In certain cases, it is possible to approach 1000:1 contrast ratio with LightBoost on some of the better 27" models.
...Bottom line, you will be wanting to choose a compromise picture setting based on preferences.Best Color
-- If you want a color/contrast champion for LightBoost, the VG278H and XL2720T is probably your best bet.Minimum Artifacts
-- If you want a fast-responding panel with very clean CRT effect (minimum possible LightBoost artifacts) or minimum possible 3D crosstalk, the VG248QE and XL2411T is your best bet.
