Ask Slashdot: Why Don't HDR TVs Have sRGB Or AdobeRGB Ratings?
dryriver writes: As anyone who buys professional computer monitors knows, the dynamic range of the display device you are looking at can be expressed quite usefully in terms of percentage sRGB coverage and percentage AdobeRGB coverage. The higher the percentage for each, the better and wider the dynamic range of the screen panel you are getting. People who work with professional video and photographs typically aim for a display that has 100 percent sRGB coverage and at least 70 to 80 percent AdobeRGB coverage. Laptop review site Notebookcheck for example uses professional optical testing equipment to check whether the advertised sRGB and AdobeRGB percentages and brightness in nits for any laptop display panel hold up in real life.
This being the case, why do quote-unquote "High Dynamic Range" capable TVs -- which seem to be mostly 10 bits per channel to begin with -- not have an sRGB or AdobeRGB rating quoted anywhere in their technical specs? Why don't professional TV reviewers use optical testing equipment that's readily available to measure the real world dynamic range of HDR or non-HDR TVs objectively, in hard numbers? Why do they simply say "the blacks on this TV were deep and pleasing, and the lighter tones were..." when this can be expressed better and more objectively in measured numbers or percentages? Do they think consumers are too unsophisticated to understand a simple number like "this OLED TV achieves a fairly average 66 percent AdobeRGB coverage?" -
Lenovo Looks To Commemorate 25th Anniversary of IBM's Notebook Brand With Thinkpad 25 (theregister.co.uk)
New submitter Provocateur writes: Lenovo will be marking the 25th anniversary of IBM's well known notebook with the Thinkpad 25. Andrew Orlowski writes via The Register: "The long-awaited 'retro' Thinkpad will be based on the guts of a contemporary T470 laptop, Lenovo's business workhorse, according to a German certification site. Lenovo inherited IBM's notebook brand 12 years ago, and with it a design classic. However, in 2012 Lenovo saw fit to 'modernize' the iconic keyboard, along with other unwelcome changes. This didn't meet with approval from some stalwarts, who clung to the superior X220 and T420 lines, the last that you could buy with the 7 row QWERTY. Two years ago Lenovo's design chief Dave Hill acknowledged that some people 'would stand in line' for the classic version. In June, Hill confirmed that for the Thinkpad's 25th anniversary this year a retro edition would indeed be produced, which Hill promised 'will embody many of the things people asked for.'
The German certification site has found the 'Thinkpad 25' variant described as a Thinkpad T470 here (hat-tip to NoteBook Check). A Chinese notebook forum has a picture purporting to be the Thinkpad 25." -
XBMC Running On an Atom-Based MID
reborn writes "Someone's got XBMC running on one of those MIDs. This one is a Compal Jax10. It runs Linux and is powered by an Intel Atom processor clocked at 800Mhz along with Intel's GMA500, which is basically a licensed PowerVR SGX GPU. Except for the better GPU (and its screen and keyboard, of course), it is similarly specced as some of the lower-end netbooks. XBMC would make a great portable media player, given its ability to play media off the network and virtually all file formats, but in the end it depends on the price-point of these MIDs. Here's the video."
