Lightroom 5 not rendering the color red correctly

Question

Out of the blue, LR5 has decided to render red as a dark orange - similar to the orange in the SF Giants team colors.  But red in the LR5 import previews is correct.  It's also correct in a different editor, Faststone Image Viewer and Irfan View.
It's orange when opened in Camera RAW 8.1 from PS Elements 10.  So the culprit would seem to be Camera Raw 8.1.

Answer 1

Couldn't you reach 120 Luminance in Eye One Match in advanced mode using the display's Brightness control? Are you using on the 'Custom' display preset mode and adjusting the RGB controls in Eye One Match for 6500K? Try downloading the latest Eye One Match v3.6.2 software, uninstall what you have now and reinstall with the new download v3.6.2. Something's wrong with the calibration process.
Please provide your display control settings, including Brightness, Contrast, RGB Color, and any other display control settings. Here's what TFT Central used:
Calibrated Settings
(Custom mode)
luminance (cd/m2)
121
Black Point (cd/m2)
0.18
Contrast Ratio
672:1
Firstly I calibrated the screen using LaCie's software suite while also changing the monitor to the 'Custom' preset mode, affording me access to the RGB colour controls. During the calibration process the screens brightness was adjusted to 20%, with contrast being left at 50%. RGB values were altered to 92, 90 and 98 respectively. It should be noted that OSD adjustments only form part of the calibration process with the majority of changes being made automatically at the graphics card LUT level.
After calibration, the results of the test and report were far more pleasing! Luminance was corrected nicely to 121 cd/m2, with black depth being improved also to 0.18 cd/m2. This gave us a static contrast ratio of 672:1 which was adequate. The gamma was now corrected to 2.2, and colour temperature was also now recorded at 6477k (<1% out). Most impressively the colour accuracy was improved drastically, with dE average being only 0.5, and maximum being only 1.0. LaCie would consider colour accuracy to be excellent here, and this was certainly a very pleasing improvement to the default factory settings.
