To test today, we are using a LaCie calibration gun along with specific software to accurately measure the readings. We tested the 2D elements of the Philips Brilliance P-Line 241P4QPYKES via a high end Core i7 Precision laptop featuring Quadro 4000M discrete graphics w/ DisplayPort out and a desktop system powered by a GTX670 graphics card.
We measured the Gamut out of the box and the 241P4QPYKES returned a reading of 2.19 which is excellent. We manually adjusted the gamma to 1.8 and the panel returned a 1.8 result which is reference.
Colour response is excellent at the default settings with a well saturated range of tones. Text focus was also sharp and backlighting quite consistent across the width of the panel. There is some bleeding at the edges which is expected at this price point.
Panel linearity is also well above average and perfectly fine for all but the most demanding of tasks.
Black Definition is impressive with dark blacks presented in a very convincing manner. Philips claim their SmartContrast is 20,000,000:1, which is a dynamic rating and for the most part we think it works well. Blacks could be slightly better, but for the price point, we have little to complain about. The edges of the panel shift from around +5% to +12%, but again this is very impressive.
We watched several Sci-Fi Blu-Ray films with the Philips Brilliance P-Line 241P4QPYKES and felt it was as good as we have seen in the £200 sector. Images produced were clear, with high levels of contrast.
White purity is a weak point of this model and I found it a little disappointing as achieving a very bright, pure image was difficult. The overall Brightness of the panel could be better, rating around 245 nits in our test. The panel fluctuation rated between +5% and +15%. To be fair this is not really noticeable unless you are viewing a high definition media file displaying very bright outdoor situations. The corners of the panel were the worst, and we recorded two sections of ‘pooling' close to the center point of the screen offset to left and right.
Panel uniformity is very good with only slight distortion, closer to the sides. Colour accuracy is also commendable, although we would be careful when using some of the preset modes as they can dramatically change the settings. Gradients were reproduced very closely with only minimal banding evident.
Viewing angles were slightly disappointing on both horizontal and vertical planes, falling short of the best IPS screens we have looked at this year. Pixel response rated between very good and excellent.
I can't say I noticed any motion blur problems during some gaming sessions, so no concerns in this regard either.
This is an extremely efficient panel, demanding only 33 watts after we calibrated it. With very high (unusable) settings it demanded 50 watts at the socket.
