Several issues could cause such a color cast. do you think my Spyder is faulty? or could it be the RGB screen is difficult for the Spyder to accurately work with (I have read that earlier models had trouble with LED RGB displays) or could it be another reason (including me being an idiot) Their screens are pretty poor at the best of times so the differences was just a different kind of poor, if you see what I mean I have also lined up my HP Envy 17 with it's 100% sRGB screen (according to the Spyder), which gave poor result with the Spyder, but nothing like as bad as the Dell result and also I tried the Spyder on a couple of Acer laptops I have. As they have not been conditioned by staring at my screen for weeks they should be unbiased witnesses and as experts in colour matching, their opinion must have some credence. Every single one of them said it (the Dell) looked awful and once I showed them the original default settings they said they easily preferred them.
Anyhoo, as a professional outside broadcast TV sounds engineer, i thought I should take advantage of the many qualified Vision Engineers I work with and give them a look. As an old saying goes "Accuracy implies precision, but precision does not imply accuracy". So i rechecked and tested etc and after 6 attempts, I saw great consistency with the results, but always poor colours. I checked picture taken with different cameras and they all looked awful. Peoples faces looking like beetroots! As a reference, documents that are mainly whitish in their appearance (WORD for instance) looked decidedly greenish. Everything seem to have a slight shift to green although Reds were super strong and saturated. I know many people will think I should get used to the new colours, but it is much worse than that. Anyway, the 'not so good' bit was how the screen looked. It also gave a fairly high Adobe RGB score. which for a laptop I thought was pretty good. It told me I had a wide gamut monitor and eventually said I had 99% sRGB gamut. So I checked my display was set to default, left it on for ages (it is well run in by now too) and let the Spyder go to work.
Out of the box the Dell looked very vibrant and a little over saturated, especially in the Reds.
I recently bought the above Spyder 4 Pro to compliment my new Dell XPS 15 Laptop with RBG display.
