Matthew N. Henry

The Philips 498P9 Brilliance is a SuperWide curved Liquid crystal display with a forty nine-inch (124cm) diagonal and 32:9 facet ratio that can switch a dual screen established-up. It offers the equivalent of two 27-inch QHD (2,560 x 1,440) displays facet by facet. You can screen the movie from two PCs and flip a solitary keyboard and mouse back again and forth involving the PCs employing the created-in KVM swap.

Finished in a textured black, the styling of the 498P9 is unobtrusively small and the only noticeable branding is a smaller PHILIPS emblem in the the centre of the bottom edge and ‘Brilliance 489P’ on the decreased still left corner.

Consumer controls

Consumer handle is through the regular row of buttons, hidden less than the edge of the enclosure in close proximity to the bottom appropriate corner. The fifth button, very last on the appropriate, is the electrical power ON/OFF button. With the screen turned off from this button the 498P9 is nevertheless consuming close to .3 Watts. There is a legitimate electrical power ON/OFF rocker swap positioned subsequent to the IEC electrical power socket. When on and in normal procedure the 498P9 typically consumes 77.2W and has a ‘B’ power rating. Our measurements clearly show .3W and 63W for the review sample. Two normal 27-inch QHD displays with an ‘A’ power rating could possibly consume 50W to 55W put together.

The other 4 buttons are context similar, dual-function buttons. The very first is the SmartImage scorching critical: recurring presses cycle through the eight SmartImage solutions, with a ninth option to change SmartImage off. With the OSD (on-display screen) menu chosen this results in being a return-to-prior-menu-level button. The second button selects for sign input and the 3rd is a customisable person function button. With the OSD displayed, these two buttons are up/down menu navigation buttons. The fourth button possibly opens the OSD or, with the menu open, confirms a collection.

The person handbook mentions a handheld distant, but this is only available in China.


A created-in 5W stereo electrical power amplifier drives two interior loudspeakers with downward struggling with grilles positioned together the bottom of the screen enclosure. Audio input is through the HDMI or DisplayPort connections.

Automated impression optimisation

Prime ZDNET Assessments

Like quite a few Philips screen items in the very last few several years, the electronics driving the screen on the 498P9 consists of the computerized impression optimisation capabilities SmartImage and SmartContrast. For both of those of these capabilities, the incoming movie sign is analysed and dynamic adjustments are built to the screen parameters. Both equally can be turned off, if needed, through the OSD.

SmartImage dynamically adjusts distinction, color saturation and sharpness according to a chosen content type. It features a option of Movie, Match, Economic climate, LowBlue mode and SmartUniformity.

SmartContrast dynamically adjusts the brightness of the backlight to offer the best possible impression distinction. It can also support to reduce electrical power use.

Display screen technological know-how

The 498P9 has a 48.8-inch diagonal (124cm) Vertical Alignment Liquid crystal display panel with a 1800R curvature (a 1.8-metre radius). The indigenous resolution is five,120 by 1,440 pixels with a pixel pitch of .233 by .233mm.

Color gamut is specified as 121% of sRGB, 103% of NTSC and ninety one% of Adobe RGB. Which is great for a W-LED backlit VA Liquid crystal display. Displays with quantum dot backlights can do better, while: 1 of the few Philips screens to use a quantum dot backlight, the 436M6, features a gamut of one hundred forty five% of Adobe RGB.

The color gamut for this screen is noticeably better than would ordinarily be expected for a classic VA-Liquid crystal display panel. Rather than use a quantum dot backlight to increase color gamut, Philips has utilized a technological know-how it phone calls Extremely Vast-Shade. This achieves an improvement in gamut by tweaking the chemistry of the backlight LEDs and the transmission traits of the color filters in the Liquid crystal display panel for a better response match.


Spectrogram of the normal backlight W-LED showing that, although the blue spike from the LED is a great match for the blue Liquid crystal display filter transmission curve, the rest of the output is not as great a match for the green or crimson filters. Standard filter responses are proven as dotted lines.

W-LEDs typically utilized in screen backlights are noticeable blue LEDs with a yellow phosphor, and although their gentle appears ‘white’ to the human visual procedure, it is not a notably pure ‘white’. This is ordinarily not a great match to the response of the R,G and B color filters in an Liquid crystal display panel, which boundaries gamut.

Every 498P9 is equipped from the manufacturing facility with a calibration chart. Brightness and color uniformity are calculated at 25 details throughout the screen. Relative to the centre stage, measurements have to be involving ninety seven% and 102% for brightness uniformity and fewer than 2 for regular Delta E.



This diagram of the 489P9 I/O connections is from the person handbook.  

Impression: Philips  

All connections to the Philips 498P9 are downward struggling with together the prime of a recess that runs together the back again of the screen, earlier mentioned the decreased edge. Seen from the back again, the 3 pin IEC socket for the electrical power guide is situated at the still left end of the recess, together with a mechanical electrical power on/off rocker swap. The I/O connections are grouped at the appropriate end. The movie connections include two HDMI connections 1 and 2 which are HDMI 2. compliant and 1 DisplayPort connection which is DP1.four.

A created-in USB 3.2 hub is provided which has two upstream connections and 4 downstream. Just one of the downstream connections supports BC 1.2 quickly demand. A 3.5mm jack socket caters for headphone connection. 

The USB hub supports Keyboard Movie & Mouse (KVM) switching for use when the screen is related to two PCs (in fact it’s keyboard and mouse switching). Switching is achieved possibly through the OSD menu, or the Consumer Perform button — the 3rd of the 5 person controls — can be assigned as a KVM toggle. While Philips claims in the literature for the 498P9 “A effortless button makes it possible for you to quickly swap involving sources,” there is no trace of a committed KVM button on our review keep track of.

Included extras

Included with the 498P9 are an IEC mains cable, a DisplayPort cable, an HDMI cable, a Rapid Start leaflet, the calibration sheet and a person handbook on CD.  



Impression: Philips

The 498P9 is a neat all-in-1 alternative for people who would usually want to use two large Quad Hd displays. The use of a SuperWide panel ensures impression uniformity and color stability, which is generally additional difficult to accomplish with two independent screens.
In use, though it can be operated as a entire-width five,120-by-1,440 screen, it can make minor perception to do so for general computing tasks. At entire width, although handle menus stay together the edges of the screen, pop-up handle panels, net web pages, or textual content documents obviously show up in a slender strip 1 quarter of the display width, down the centre of the screen. Environment document zoom to site width utilises the complete width of the screen, but vertically only displays a strip of probably 10 sentences. Entire-display YouTube movie occupies the centre 50 % of the screen.

The Extremely Vast-Shade gamut-boosting technological know-how, together with Philips smart impression processing, does control to extract really great impression good quality from the VA Liquid crystal display panel in the 498P9.

The created in audio lacks bass but is usually of fair good quality and is unquestionably effortless, although the created-in KVM is crippled by the absence of the promised ‘convenient button’. Ideally this would be an external button on a traveling cable that could be situated in close proximity to a keyboard and mouse.
