Of course the operation of the XPR system is identical in both cases so…Īnd these are the features that Texas Instruments announces in the official pdf of the chip Let’s go straight to the point and find out how XPR technology works and many questions will be answered.įor reasons of economy we will deal only with the case of DLP projectors that wear the small 0.47″ DMD chip with resolution 1920X1080 and not those with 0.66″ with resolution 2716X1528. XPR technology is what has allowed the DLP projectors of the last years to be called 4K and advertised as 4K, it is the trick of Texas Instruments we would say to give 4K resolution to the manufacturers of DLP projectors while selling them the classic DMD chip with resolution 1920 × 1080 who has been manufacturing for 10 years now, good eh? But we strangely see 4K… how is this done? Now you should read the rest of the article… Hmmm… very short answer, and you may save yourself from reading the rest of the article, no, these projectors are not 4K UHD projectors nor of course they are not giving UHD resolution to our screen. Marketing trick or indeed these projectors deliver the coveted 8 million pixels of UHD resolution on our screen so the companies are doing well and claim that these projectors are 4K? The DLP manufacture companies the mention in the specs of these projectors that their resolution is 3,840X2160 but in fact they do not mention anywhere that this resolution is not the native resolution of the panel but is achieved mechanically by a device for doubling or quadrupling the pixels that has been installed between the DMD chip and the lens. 4K DLP projectors have been on the market for a long time now and are undoubtedly the most economical solution if one wants to live the experience of watching UHD HDR 10+ material in his personal home cinema.
