Philips BDM4065UC Monitor Review: really big picture

Ultra HD monitors are quite popular. Although still significantly more expensive than their HD counterparts, the prices are not comparable with what they cost at launch. Disadvantage for smaller sizes remain the pixel size, which requires good software scaling. At Philips BDM4065UC you have will not notice, because this screen has a diagonal of 40 inches, or roughly one meter. Another advantage: it is not even that expensive.

For televisions is that diagonals smaller than 50 inches actually make little sense to manufacture Ultra HD resolution: you’re usually not close enough to see much difference with the still more common 1920×1080 Full HD. Since it is a thing to barter, but for most users in most situations it goes on.

On the desk, the situation is different because there you usually not much more than 50 cm from the screen. The difference between 82 ppi for Full HD 27 inch and 28 inch at 157 ppi is significant. Whoever longer has put behind a large screen knows it, especially for games yields a more immersive experience. Just as the movie screen that occur in comparison with the average home television.

So it’s nice that we are seeing an increasing number of 28 and 32-inch UHD monitors in the market. Now we have that first type already discussed the necessary and we’ll come back to the larger size, but the screen that is the subject of this review, goes one step further. Philips BDM4065UC measuring as much as 40 inches and as a pixel density of 110 ppi, similar to either 2560×1440 WQHD 27 inches.

A diagonal of 40 inches, or more than a meter, very big to put on your desk. We rarely ever hear from readers who use a Full HD television as a monitor of that size, but on a regular viewing distance you still less summary. You can not see at a glance the whole screen – that should take you further away. On the other hand, you are almost literally the middle of a game.

Upon introduction, the price of the BDM4065UC was 699 euros, but the dollar rose against the euro has a price of 749 Euros at launch plausible. It will take some time – if at all – for that price really goes down. This is also reflected in the current providers: Philips partners only fixed price of 749 can live up anyway, the rest is overhead.

In fact, the screen is equivalent to four 20-inch 1920×1080 monitors, but there will never be a lot of it. 21.5 cq. 22 “monitors with Full HD resolution, there are considerably more. You have them for less than 100 euros, so for roughly 400 euros you have the same amount of workspace, with this Philips. However, you’ll, of course (especially in the lower price range) fairly wide bezels that interrupt the image and a monitor for four screens is certainly not free. The cheapest in our Price comparison costs about 115 euros, but most are a lot more expensive. Overall, the price of the BDM4065UC is not so crazy not only do you need a separate monitor arm and you do not suffer from bezels, it is also about a VA panel, not a TN panel as the cheapest 22-inch screens And so it is time to this screen. something closer look.

We discussed the BDM4065UC earlier in Hardware.Info TV, so that delivery can you here under another look back.

Philips BDM4065UC

Philips BDM4065UC is as said a 40-inch monitor with a resolution of 3840×2160 pixels. The resulting pixel density is 110 ppi. That provides some smaller icons and text than with a typical 24-inch full HD monitor, but there is excellent to work with; as we wrote it is effective about as sharp as a 2560×1440 27-inch monitor. Scaling is not an issue, as long as you do not sit too far away.

The panel is used by the VA-type and from the factories of TPV Technologies itself. Reportedly involves the TPT400LA-K1QS1.N panel. The panel is real 8-bit, so it does not use interpolation. The screen has a slightly shiny layer, as often seen in VA panels. The reflection is not too bad as long as you light source directly above / behind you hang there is excellent work on. The backlight uses PWM over the entire brightness range. At low brightness can thus observe blink, if you are sensitive to it – most people do not suffer from this, but if you know yourself this, it’s something to consider.

The BDM4065UC stands on a beautifully designed, but not fully adjustable stand. Even tilt not a possibility – it is rather a TV stand, a copy of a monitor. Now the height such that you probably do not much want to adjust, but if your circumstances require it, you are so reliant on a separate suspension in the form of a 20×20 cm VESA mount.

A little thing that we have to mention here: in our test sample was the picture with the Philips logo below the screen covered with protective film, which appeared to be clamped between the panel and the base. It took some careful handling a thin knife to remove it. Not very nice.

Philips BDM4065UC: Connections

In terms of connections provides the BDM4065UC, as we are used Philips and AOC in this class, nice lot of connectors. It is striking that DVI is absent, but HDMI is there, in duplicate. Incidentally, its HDMI 1.4 connections, so they are at the native resolution is limited to 30Hz. One of the HDMI connectors is also suitable for MHL, though it is as far as we could ascertain MHL 2.0, so not suitable for Ultra HD.

The only way to 60Hz Ultra HD display is using one of the two connectors Display Port, a minimum and a normal copy. By default, the screen set as DP 1.1, but the menu you can change that to DP 1.2 for full refresh rate. Surprisingly enough, the screen is detected as a single display (SST) rather than as an MST-setup; that we have not seen much earlier on UHD screens.

Furthermore, we take on the monitor is an analog VGA connector – a rather odd choice, given the high resolution never distorted by a VGA cable will come, most suitable for diagnostic purposes so. The list of connections and features further includes audio inputs and outputs, a USB 3.0 hub and a set of speakers. This 2x 7W speakers would theoretically have to deliver better sound than what we usually see in monitors, so we have tried out. We were soon ready with it, because they sound really terrible, while the maximum volume is not particularly high. Any television does it better – and that are known as no fliers in audio.

For control, a joystick analog stick located in the right corner. There’s also the power button. We have intuitive OSD’s seen with a joystick at the rear of the screen (that is, for example, Samsung quite good), Philips but fails to realize that label. It works, but with the usual irritation factor.

Enough of the physical aspects, time for the test. How BDM4065UC do it in practice?

Philips BDM4065UC: Test Methodology

We test monitors in a number of ways. Most models is measured by an older Microvision road SS220 semiautomatic colorimeter. This robot not only measures the color and temperature, brightness, contrast and gamma, but also the brightness under horizontal and vertical viewing angles of 45 degrees. Also, it determines the uniformity (luminance distribution) with a comparison of the brightness at 25 points.

Because the accuracy of the color fastness of the measurement is limited to the older road SS220 CIE1976 standard, we also use a X-Rite colorimeter i1 Display Pro in combination with the advanced Spectracal Calman 5 software to also herewith, by measuring the monitors. In addition, we record maximum and minimum brightness, contrast, gamma value and color and gray deviations based CIE1994. We do this because the modern CIE2000 standard is still less widely supported and we have a lot of comparison with the older standard. The new, we will in time gradually introduce into our test procedure. We use the i1 / Calman combination standard measurements such as the screens out of the box; if there is an sRGB mode, we set up the screen thereon for this measurement. If there is an AdobeRGB mode, which we measure separately.

Besides the aforementioned display measurements, we usually also measure reaction time, overshoot and undershoot and the input lag. When gaming screens we do that anyway, to other screens where this represents a potential meaningful result. For the first three tests, we used a photometer in conjunction with an oscilloscope. For the input lag test, we use both a visual comparison with a CRT (cathode ray tube) monitor using high speed photo recordings, and (where possible), Leo Bodnar input lag tester. Who tester for the output signal is limited to 1920×1080 and our experience is that the results in displays with higher resolution poorly reproducible, or unpredictable. Therefore we mention that results are not always at higher resolution screens.

Finally, we measure the energy consumption using calibrated flowmeters, both displaying a full black and full white image, and in the standby and off mode.

Philips BDM4065UC: Settings for tests

In all tests, we tested the monitors as they come out of the box: so most users will this also work. We base these exceptions: the color temperature measurement, we try to put in the position of the screen where the 6500 Kelvin closest is approached, the sRGB and AdobeRGB measurements we use as said the positions above, provided that they are present. If no sRGB mode is present, we do the Calman measurements in the standard (after restoring to factory settings) display. Furthermore, we do all the measurements at 100% brightness, both for the sake of a fair comparison, as to maintain a manageable test.

Philips BDM4065UC: Calibration

Often ask readers to calibrate monitors, or adjust the settings so that color, brightness and contrast are optimized. However, we do not, for two reasons. In the first place, the majority of the monitor, virtually all consumer models, to calibrate only in software. This means that you create a color profile for your combination of video card and monitor: that profile only works with that particular combination and then in addition to the specific screen that you use. Even identical monitors have namely small differences which require a different profile. This sets so actually the signal of your video card.

Only monitors for the professional market and then the section on graphics applications have the ability to calibrate the hardware. Still remains that the institutions that we have does not necessarily make sense for a copy to purchase the reader. The second reason is that calibration is a time-consuming process. What we can do is report or our test results indicate that calibration will lead to (almost) perfect view. Calibration always delivers an improvement, but the required colorimeter is too expensive for most users to do this themselves – good copies cost more than most consumer display devices.

Philips BDM4065UC: Targets

For clarity, we see preferably values above 250 cd / m² for maximum brightness and under 0.3 cd / m² for minimum brightness. A brightness of 300 cd / m² is actually not useful except for use in extremely bright environments and thus provides no extra points. Maximum contrast is ideally above the 800: 1, 1000: 1 is good since (well) above is excellent. In addition, we have to note, however, that contrast values in darkened rooms often do not fall out and that a much lower contrast higher than 100 to 300: 1, in practice, is exceptional. The figures given are mainly an indication of performance in use: higher is better.

For color temperature is a measure of 6500 Kelvin as close as possible desirable; this corresponds to normal daylight exposure. Values between 6000 and 7000K are good enough for ordinary use, as far below or above yields negatives on. Values between 6400 and 6600K are excellent.

The gamma value should approach as close as possible to the 2.2. We should remark that this is also important that these measurements from 10% to 100% brightness also so close as possible to this 2.2 because offsetting outliers are not desirable.

The color and gray-value deviation is sufficient if it is less than 5, good as it is less than 3 is excellent and if it is less than 2. Values above 5 ensure that we will not recommend the product for other than incidental imaging.

The reaction times, we note both parts (rise & fall) when combined. The key values are not the combined 0% -100% -0% and 20% -80% -20% values, as the ‘optimal’ measured values. Which show the results of the institution that produces minimal overshoot and undershoot, but the least desirable approach speed of 16 ms. We note both the results without overdrive as maximum and optimum overdrive, provided above settings are available. Provided artifacts remain limited by under- and overshoot, its values of 16ms and less adequate, and well below 10ms and 6ms and lower outstanding.

Input lag is a phenomenon which is contesting the disturbing effect, but values greater than 16 ms ensure that we will not recommend a screen for gaming. It is important to remember that the results of the comparison with CRT exclusive the response time of the panel to be read and that of the Leo Bodnar tester including those times.

For the power consumption depends on the judgment of the measured value from the screen size, resolution and color space (Adobe RGB monitors consume more complex by a backlight). What is certain is that a stand-by power above 0.5 W and a power consumption over 0W not be desirable. A stand-by consumption higher than 0.5W is also in breach of EU law.

Test results energy consumption

The power consumption of the monitors has improved in recent years. Consumed a 27-inch screen in 2008 from more than 80 watts, anno 2013, we measure consumption that far more than half lower. How small the screen size, the lower the consumption. Because TFT displays actually always lit, the power consumption varies between a full white and full black image is not very much. Dynamic lighting can affect, but usually works so bad that we would not recommend.

What is important to know is that IPS and VA monitors consume more power when displaying white image, but so far most used TN technology precisely the most consumed in black image. This screen is the difference between black and white is very low; just under 80 watts is given the dimensions it outright. Furthermore, it is important that the EU prescribes that monitors (and many other electrical equipment) that end up in the market from 1 January 2013 no more than 0.5 watts in standby mode may consume, where it was still one watt in 2012. Off-mode Philips BDM4065UC is real, then it consumes neatly 0 watts.

Philips BDM4065UC: Conclusion

We can not avoid: Philips BDM4065UC is indeed an exotic big screen, but for the price it is a very good screen. In fact, it’s one of the better Ultra HD monitors we’ve seen in our lab. The combination of resolution and diagonal allows them to work with an operating system that is not scale well and the test results are almost all excellent. Response times are ‘just to’ for games, but as long as you are not very demanding player of fast FPS are games (and we suggest you’re a 144Hz screen instead of an Ultra HD monitor), you may be fine with the feet . In all other respects, we really have no criticisms.

There is no doubt that not everyone has a screen of a meter will put on his desk, so it should be clear that this is only of interest to those who already held a large monitor, or a change from a multi-monitor configuration. CAD / CAM applications, traders, but also programmers, image editors and gamers the immense work surface but actually benefits. The price is, as with all associate screens, firm but not absurdly high. Indeed, most 32-inch Ultra HD monitors cost at least 1,000 euros at time of writing.

Who BDM4065UC television wants to use the device or must take into account that does not have HDMI 2.0 inputs and thus is not suitable to 60Hz content again: there are no external tuners with a DisplayPort output, as far as we to know. HTPC with a tuner is also the only option if you’re interested in that purpose. And who is looking for a 40-inch UHD TV, which can probably still find something cheaper. The question is whether you can find a device with such a low inputlag, while in terms of setting possibilities decidedly less sides can then monitor the menu of this product. OSD is admittedly not very comfortable to use, you can anymore for use with a computer than with the menu of a TV.
