In fact, not so much hit it, more slammed my head straight through it in sheer, irate frustration. You see, it uses an LED backlight, which Samsung&#8217;s press bunf confidently told me would produce a level of contrast the old CCFL kind simply can&#8217;t match.</p>
<p>And it does. Not just any old contrast, but MEGA contrast! Yes, MEGA, in capitals. In non-marketing speak that converts into a figure of 5,000,000:1, or 5,000 times higher than the standard contrast ratio on most of today&#8217;s TFTs.</p>
<p>Except the XL2370 doesn&#8217;t manage that at all. <span id="more-7375"></span>As with all of these ridiculous figures it&#8217;s a dynamic contrast ratio, and while it may be several magnitudes higher than the 10,000:1 or 20,000:1 of the best CCFL monitors, it still relies on adjusting the backlight on the fly during a video in order to maximise both the blacks and the whites depending on the type of scene.</p>
<p>Now, I&#8217;ve commented before in the magazine that I simply cannot bear dynamic contrast modes. I can count on one hand (with around three fingers to spare) the number of DCR modes I&#8217;ve ever seen that were even slightly bearable. I don&#8217;t even need fingers to count the number I&#8217;d actually contemplate using.</p>
<p>If you&#8217;ve never seen one of these modes in action, it goes something like this: during all but the most uniformly lit scenes the backlight swings wildly up and down to make shadows darker and highlights lighter in a manner that&#8217;s monumentally distracting and in no way better than what you had before.</p>
<p>The most brilliant DCR moment I&#8217;ve had was just a few days ago with the Samsung, as it looked at the blackness of a space scene in Wall-E, couldn&#8217;t tell there were stars scattered liberally across it and switched the backlight off entirely. It was certainly an impressive black level but it didn&#8217;t exactly help me follow the action.</p>
<p>Worst of all, I know the UK product managers at several TFT manufacturers hold the same opinion as I do on the subject. To them it&#8217;s nothing more than a figure the marketing department slap on the information card in the shop &#8211; and some have started doing so at the expense of any standard contrast ratio figure at all.</p>
<p>So who actually uses these terrible dynamic contrast modes? Do you have a monitor that offers DCR, and if so do you choose to enable it? Or perhaps you&#8217;ve been wondering why your films look so bad without realising your monitor came with DCR enabled by default?</p>
<p>I&#8217;m willing to admit I&#8217;m in the minority if it turns out you all love feeling nauseous during films, so if you&#8217;re a DCR fan do your best to convince me in the comments below.</p>
