ViewSonic XG2401 FreeSync Monitor Review
Unlike CRT displays, the manner in which LCD panels create an image can result in one large weakness: the image can lose contrast when viewed off angle. While we do not recommend watching an LCD at anything besides perfectly straight on, the reality is this cannot always be done.
To help give you a glimpse of what a panel will look like when seen from either above the horizontal or vertical plane we have taken pictures at fairly extreme angles.
For a TN monitor the XG2401 is not all that bad in this area and is certainly above average for its price range. By that same token this is not the same as saying the off-angle viewing profile of the XG2401 isgood; rather it is merely mediocre bordering on tolerable. As with all TN based monitors viewers will lose contrast and color fidelity the moment they are not sitting perfectly in front of the panel.
Maximum Contrast Ratio
While manufactures love to throw around “maximum” contrast ratios in the millions, the fact of the matter is that to get these high numbers they have to use “dynamic contrast” which—at best—results in overly optimistic specs. With DC turned off, the number of shades between purest white and blackest black a given monitor can display is usually in the low hundreds rather than the thousands.
The higher the contrast ratio, the better the monitor will display shades of dark and light. For IPS monitors, anything below 450:1 is unacceptable, with 500:1 or above considered optimal. For TN anything above 120:1 will be considered “good enough” for most consumers.
While TN can never compare to IPS or even A-MVA in the contrast ratio department, the XG2401’s panel is not all that bad. Certainly above average and rather good for the asking price.
To obtain the maximum number we set the monitors brightness to 100% and the contrast to 100%. The Calibrated results are taken at 120 cd/m2 with the contrast set to the default level.
A relatively small monitor with no G-SYNC module equates to moderate power usage.
