Dell has started selling its first OLED display in the US . Actually, the model was discontinued because the manufacturer was not satisfied. But apparently, Dell was able to solve the problems of the 30-inch display with 4K resolution
Dell's 30-inch OLED display Ultrasharp UP3017Q comes on the market. At least in the USA he is currently offered with a delivery time of one to two weeks. On the past CES it was said, the monitor would be adjusted because of viewing angle problems. Up to now, OLED technology in the IT sector has only spread to wearables, smartphones and additional displays like the Macbook Pro 2017. In the case of larger screen diagonals, television manufacturers in particular are panel buyers. This could change soon, because the problems with the technology has apparently solved Dell and offers the display regularly for about 3,500 US dollars. As usual, taxes still have to be applied in the USA, which vary according to the state. If you consider local taxes, the price should be around 4,000 euros, that is, the triple of what Dell requires for a similar LC display. Still, Dell Germany does not list the OLED display device. No DCI-4K resolutionThe UP3017Q is one of the monitors of the 4K resolution class with 3.840 x 2.180 pixels (Ultra HD) at a screen diagonal of 30 inches. The monitor is not particularly bright: the figure is 300 candelas per square meter. Nevertheless, the power consumption can be very high. Something over 100 watts should be typical, 240 watts are the maximum. However, the OLED panel is typically also very dark: 0.0005 cd / m2 is achieved. It is worthwhile an old trick, with LCD users years ago were inserted : A black screen should save energy at that time, which was not the case. With OLED technology, this is different, which we have measured with an OLED TV . For LCDs, this is sometimes the case, but only when techniques such as local dimming or Direct LED are used, which is more a specialty of TVs. The Dell monitor is a 10-bit panel, and the colors are as follows: Adobe RGB 100 percent, Rec.709 100 percent, DCI-P3 97.5 percent, Rec.2020 85.8 percent. The panel should also react very quickly. Dell gives 0.1 ms for a change from black to white. There is no comparison to the gray-to-gray interchanges popular with LC displays. The angle of view is indicated by 178 degrees horizontally and vertically. The OLED technology is an exception in monitors and so far predominantly found in expensive and chunky professors. With the UltraSharp UP3017Q, Dell is taking a first step on the parquet around the young display technology, which is completely different from the popular liquid crystal displays (LCD). The first OLED monitor from Dell is by no means chunky despite the image diagonal of 30 inches, but is also aimed at the professional segment. The resolution is indicated with Ultra HD 4K and is therefore 3,840 × 2,160 pixels. The screen is particularly suitable for graphics and photo applications on a PC. With a price of around 5,000 US dollars it becomes clear that it is not a product for the masses - new technology has its price. Short response time and high contrast thanks to OLED The advantages of the self-emitting organic light-emitting diodes, which are concealed behind the abbreviation OLED, are, among other things, the possible elimination of additional background lighting. While LCDs have to be aligned with liquid crystals for the color change, this is not necessary with the OLED display. This reduces the reaction time immensely. Dell gives the UP3017Q a response time of only 0.1 milliseconds - the fastest LCD monitors for players are ten times slower with a millisecond (on the paper). In addition, the technology allows for a very high contrast ratio, which in this case, Dell gives 400,000: 1 - even contrast-strong VA-LC displays usually only one hundredth of that. In terms of color reproduction, the extended gamut is served outside sRGB and Adobe RGB is completely covered by the data sheet. The color depth is 10 bits per color channel and thus 1.07 billion colors. Moreover, USB type C is called a universal connector. Further details are still to be found. 120 hertz points towards DisplayPort 1.3PC Monitors also(4k gaming monitor) wants to have learned that the OLED panel operates with a refresh rate of 120 hertz. Since neither DisplayPort 1.2 nor HDMI 2.0 Ultra HD with 120 Hz create, the solution could be with DisplayPort 1.3 because this year the market launch of the new video interface is expected, which is supported by AMD's upcoming Radeon graphics cards of the Polaris generation. At the CES the display was connected via USB type C via Thunderbolt dock. Furthermore, the Dell monitor should have a function, so that pictures do not " burn ". Since OLED displays also have lower durability than LED-illuminated LCDs, a presence sensor is installed, which switches off the screen in the absence of the user and thus protects the light-emitting diodes.
