Posesorii de MacBook Pro Retina Display continua sa se planga de problemele cunoscute popular drept “ghosting”. Am vorbit acum cateva luni de zile despre aceasta problema si atunci s- a spus ca Apple va rezolva problema rapid, insa acest lucru nu s-a intamplat. Desi problema persista, se pare ca ea ar avea legatura numai cu ecranele fabricate de catre cei de la LG pentru Apple, si desi nu puteti afla, inainte de achizitie, cine a produs ecranul unui Mac, exista sanse sa cumparati unul fara probleme.
On an IPS display, when an image such as a login window is left on screen for a long period of time, you may temporarily see a faint remnant of the image even after a new image replaces it. This is referred to as “persistence,” “image retention,” or “ghosting.” This is normal behavior for an IPS display, and the faint image will disappear over time.
You can prevent image persistence by using the display sleep feature to turn off the display when it is not in use. You can also use a screen saver to make sure that a static image isn’t on the display for long periods of time. Both of these features are on by default in Mac OS X, but you can adjust the settings as needed.
Apple a scris un document pe website-ul sau in care spune ca problema este normala, insa unii utilizatori au schimbat si 4 Mac-uri fara succes, dar este bine ca Apple le schimba. Daca ati cumparat un asemenea Mac puteti rula comanda aceasta: ioreg -lw0 | grep \”EDID\” | sed “/[^<]* pentru a afla cine l-a produs, insa dsca nuare probleme cu ecranul, atunci nu va fimschimbat. Ecranele LG au denumirea LP si cele Samsung, care nu au probleme, au denumirea LSN.
