You will be unable to uncover the lid, the hook on the cover will get broken and it will be impossible to properly close the battery compartment again. The medium one is already attached to the glasses and one small and one large one are included in the package. Page Troubleshooting as the glasses are not exposed to high temperatures.
Using paper towels should be avoided as they can scratch the lens! Page Important Safety Instructions These persons may have seizures while watching certain types of television pictures or playing certain video or computer games.
Persons who have not had any previous seizures may still have an undetected seizure condition. Page 13 Do not wear 3D Glasses as sunglasses or safety glasses. Never wear 3D glasses while driving, swimming, or operating machinery. Do not use near staircases, ledges or balconies. You may risk falling during or after use. TV you'll be watching, these XpanD glasses are good bet-hedgers. XpanD will be launching a new range the X with support for Bluetooth as well as the radio system favoured by Panasonic.
The Xpand 3D glasses are well-made and are fairly easy to install. A simple programming system, based around a single button and LED, enables you to tell the glasses which TV you're using. In its set-up mode, the brand is selected cyclically by pressing the button. The number of LED 'flashes' corresponds to a specific TV brand; if it's correct, press nothing for 30 seconds and you're done.
Hopefully, Samsung or some other third party will produce an adapter for IR models because it would eliminate this issue entirely. Only minor syncing issues are present with the Panasonic VT25 and Panasonic glasses, specifically when the head is tilted back. A viewing of Avatar on the Panasonic VT25, reveals that the X glasses provide a bit warmer picture than when viewing through the Panasonic glasses.
The added warmth is only noticeable due to switching back and forth between glasses and is not expected to be noticed through casual observation. Overall, the Panasonic glasses provide a superior picture, but the X glasses are a close second. A screening of How to Train Your Dragon 3D on the Samsung C exposes a disappointing picture that is not only warmer than the image when viewed with Samsung glasses, but more importantly, lacks contrast with the letterbox bars appearing more gray than black.
Upon first noticing this difference, we were confident that the display could be calibrated to make the X glasses produce as good a picture as the Samsung glasses.
Naturally, we tried to adjust the brightness of the display with the AVS HD black clipping pattern. Frustratingly, the result of the brightness calibration was the same whether using the XPAND X glasses or the Samsung glasses; yet when viewing with the X glasses, black was definitely not as black as when viewing with the Samsung glasses.
Further, we attempted to use a colorimeter to at least measure the visible difference. The meter was placed over the glasses and held up to the display as close as possible while trying to measure minimum luminance levels with a 0 IRE pattern pure black test pattern. In this state, the glasses are off and cannot sync with the IR signal from the display.
The measurements were nearly identical. Surely, there is an obvious difference when the glasses are on. The only reasonable explanation for this difference in brightness is that the time the XPAND X glasses have the shutters open is longer than the Samsung glasses.
We know that the displays produce a much higher light output in 3D mode to compensate for the dimming effect that occurs when viewing through active shutter glasses, thus, if the shutter is open a longer period of time, the eye senses more light. In contrast, the Samsung lenses have more of an amber tint and the Panasonic lenses have a somewhat brownish tint.
This difference appears to be what is causing the warmer image when viewing with the X glasses. Both the Samsung and Panasonic displays have many calibration options that could most likely be employed with a colorimeter to correct for the additional warmth provided by the X glasses.
However, once this type of calibration is performed, use of the Samsung or Panasonic glasses will likely appear too cool. Can active shutter glasses truly be universal?
