The competing devices offer much brighter display and the peak brightness of the device was measured at 1278 CD\/m\u00b2, relatively low for its category. In a positive note, the device manages the screen well, using a high frequency PWM (modulation of the width of the impulse) at 3848Hz, which is generally more comfortable for the eyes.<\/p><div id=\"forum-1195777325\" class=\"forum-content forum-entity-placement\">\t\t<div class=\"ad-wrapper\" style=\"width:100%;min-height:250px;text-align:center\">\r\n\t\t\t<!-- In Article Blog -->\r\n\t\t\t<ins class=\"adsbygoogle\"\r\n\t\t\t\t style=\"display:block; text-align:center;\"\r\n\t\t\t\t data-ad-layout=\"in-article\"\r\n\t\t\t\t data-ad-format=\"fluid\"\r\n\t\t\t\t data-ad-client=\"ca-pub-3476569516614521\"\r\n\t\t\t\t data-ad-slot=\"9829044906\"><\/ins>\r\n\t\t\t<script>\r\n\t\t\t\t (adsbygoogle = window.adsbygoogle || []).push({});\r\n\t\t\t<\/script>\r\n\t\t<\/div><\/div>\n<p>The reproduction of the color was a strong point, with natural colors and accurate in all lighting conditions.
