 About RMIT
If you're looking to replace monitors or roll out new PCs, it's hard to go past one of these 15-inch LCD monitors. But is the 15-inch form factor in danger of becoming extinct?
It has been 10 months since we last looked at LCD monitors in the August and September 2003 editions of Technology & Business. Those two reviews were general looks into the growing popularity and affordability of LCD monitors, from 17-inch units up to 21-inchmodels. This current review is focusing on the mainstream desktop 15-inch models currently on the market.

When we say "mainstream", however, this is starting to look like one of those instances where the manufacturers are looking out for their profit margins rather than listening to customer needs. Already some major vendors are abandoning their 15-inch models and selling only 17-inch or larger. While we are usually inundated with LCD monitors whenever we review them, this time around when we asked for 15-inch monitors, we only received five. Sure, we can't think of many people who would say no to a 17-inch LCD monitor on their desk -- unless they're really short on space -- but the accounts department may have other ideas. So treasure this review, it may be the last time you see 15-inch LCDs in these pages.

LCDs now carry many advantages over CRT displays, the most obvious of which are space saving and power saving, not to mention the elimination of the radiation factor. Some people are still reluctant to take up LCDs because of the slower refresh rate, however many vendors now have faster LCDs. For the average office worker who uses their monitor for e-mail, wordprocessing, spreadsheets, and database applications, it probably makes little difference. Also, with corporate offices now much more in the public eye, style surely must be another incentive for some offices to make the move away from CRT. For more information about the pros and cons of LCDs vs CRTs, take a look at our Monitor Buying Guide.

Something to keep in mind here when narrowing down the field if you are looking at upgrading from a CRT monitor to an LCD -- particularly in the larger sizes, 18-inch or bigger -- it's worth checking your existing video graphics card has a DVI port on it. And this applies vice versa; if the LCD panel doesn't have a DVI input then you are limited too.

The difference in image reproduction on some monitors between the standard analogue 15-pin D-Sub (VGA) port and the digital DVI ports is amazing, somewhere around 10-15 percent better visible image sharpness and overall image quality.

You can purchase small adaptors that convert from DVI to 15-pin D-Sub and though not providing the same benefits as a direct port connection, they may improve the image slightly over the standard straight 15-pin connection. This is something you will need to test yourself, as it would depend on your system and monitor choice.

Generally, the smaller and cheaper LCD monitors do not support DVI input. With the smaller size comes lower resolutions of between 800 x 600 or 1024 x 768 and the image quality is generally quite acceptable even through the traditional analog 15-pin D-SUB VGA connection.

AOC LM520i
AOC LM520i
The AOC unit is quite a stylish matt silver over matt black. The unit itself is very attractive to look at, however it has a kind of cheap plasticky look and feel to it, this may be in part to do with the matt colour scheme.

The rear of the monitor has two different sets of wall mounting threads available for use, and the base is readily removed. There are only two ports on this monitor, one VGA port and one standard IEC power socket. It is interesting to note that all the units submitted for this review have their power supplies built into the monitors, whereas the last LCD review we performed several of the manufacturers opted to use external "brick" power adaptors. The base itself is relatively sturdy, however with the screen pivoted all the way forwards it can be a bit prone to tipping over. The base also has no swivel functionality, just pivot forward and aft. The rear of the unit also has a Kensington security lock port.

Once powered on, there was a handy "auto" setup button which made the initial calibration/setup for us. We found that only very small tweaking was required when running through the Display Mate setup routine.

The blacks were very black on the AOC panel, however they tended towards blending with the greys too much, not giving much contrast differences. The video playback was acceptable, however fast moving/flashing scenes tended to tear a little; the pixellation also of these sequences was also quite pronounced.

While it's not a well known brand, we feel this monitor offers good value for money, in a no-frills solution.

Hallmark Viewmaster ES555

The Viewmaster unit is a stylish matt silver over gunmetal grey. The rear of the monitor has a set of wall mounting points. The base is easily removed by taking out two screws. There are two ports/sockets on this monitor, the first is a standard IEC power socket and the second is an audio jack for audio input. The video input is via an integrated VGA cable that is just over 1.5 metres in length. Note that this cable is not removable, so should the cable or plug ever become damaged or need replacement, the entire unit would need to be returned to a service centre. (This is also the case with the ViewSonic VE510b monitor.)

The base of the Viewmaster unit is quite sturdy, while not offering any swivel capabilities the pivot forward and aft would be more than sufficient for most applications. The rear of the unit has a Kensington security lock port too.

When we first plugged this monitor in it automatically went through a setup procedure, which resulted in the image on the display looking very dull, blurred, and out of focus. We immediately suspected that something was wrong, however a short flip through the menu showed that the phase was way out and once set more conservatively we found the screen image to be quite sharp. We then ran the auto setup again which can be accessed from the menu and found that the brightness also improved dramatically.

Image quality was reasonably good in our performance tests. During video playback, there was some slight tearing and pixellation however nothing to be really concerned about. The depth of field also was not as good as some of the other monitors.

This is a very nice professional looking display with inbuilt speakers, but no headphone port. There is no DVI input or swivel on the base, also the integrated video cable may become a headache to replace. Overall this is a decent monitor at a reasonable price.

IBM ThinkVision 6636-AB1
IBM ThinkVision 6636-AB1
The IBM monitor is very attractive and certainly would blend well with most offices these days. The rear of the unit is covered by two very well designed removable plastic covers, these not only hide the ugly parts of the rear of the monitor but they also act as cable guides. The base can be easily removed.

There are two ports on this monitor, one D-SUB 15-pin VGA port (DB15F) and a standard IEC power socket. The stand is very strong and heavy, it would be extremely difficult to tip this monitor over. The stand offers a good deal of fore and aft movement however there is no swivel capability. There is also a Kensington security lock port at the back of the unit.

The IBM monitor, like the AOC, has a button for automatic setup of the display. The image quality in our tests showed up rather average. In video playback, the skin tones seemed a little washed out, while the blacks and contrast in dark/greys was very good. Despite all our tweaking, we could not get the monitor to display more than average skin tones. Fast motion also created tearing however there was very little pixellation during those scenes.

The IBM panel is overall a very nice LCD panel and performs quite well. Remember, though, there is no DVI input, no swivel functionality to the base, and no speakers/multimedia. For the brand name, it is competitively priced.

Philips 150B
Philips 150B
The Philips 150B is an extremely attractive monitor, silver with gunmetal grey highlights. The base can extend to give an extra 60mm in height, so bonus points go to smart ergonomics in the design.

The rear of the unit is has a removable plastic cover built into the adjustable base which acts as a cable guide. The base is also easily removed to allow wall mounting. There are five ports/sockets on the rear of this monitor, one D-SUB 15-pin VGA port, one DVD-D digital video port, a standard IEC power socket and two audio jacks, one for headphones and one for audio in. There is also a Kensington security lock port at the back of the unit.

The base offers an amazing deal of fore and aft movement, but it understandably becomes unsteady at extreme angles. The base also features a swivel ability.

We tested the 150B using analog video input so we could perform a equal comparison between this monitor (which also has DVI input) and the other monitors in this review (which only have the analog 15-pin input). The initial configuration is via an automatic setup which is launched by pressing the "auto" button.

Once the auto setup had completed, the image was bright and sharp. The whites were very crisp and the black text stood out clearly. Contrast was particularly good. Video playback tests were very good with excellent depth of field and very little tearing or pixellation even in the faster scenes.

The Philips 150B was the only monitor with DVI in this review, and considering its very good performance via the standard analogue port, the use of DVI could only provide better results. It was also the only monitor here with a height-adjustable base and a base that allows swivelling, which considering the relatively light weight of these monitors is a slight bit of overkill.

The 150B was also one of only two monitors in this review with in-built speakers. Overall the 150B is very well designed, finished and particularly attractive. This monitor is also perfect for use in a multiple-display arrangement due to its very small side bezels (17mm). A very hard monitor to go past and is certainly worth shortlisting for evaluation.

ViewSonic VE510
ViewSonic VE510
The Viewsonic monitor is black with chrome highlights. The bezel is 17mm wide all around the monitor, which is great for users looking to deploy these units side-by-side with dual display adaptors.

ViewSonic has been able to keep such a small bezel because the five control buttons are all embedded into the base of the unit which is integral to the monitor and cannot be removed. It can however be flipped up behind the monitor to allow wall mounting. The rear of the unit has the four standard wall mounting threads covered by removable rubber plugs. There is only one port on this monitor, it is a standard IEC power socket. The video signal comes in from a two-metre video cable and 15-pin plug. The unit's base is surprisingly sturdy, it would be very hard to tip this monitor over.

The stand offers a good deal of fore and aft movement, but there is no swivel capability nor is the base removable. There is also a Kensington security lock port at the back of the unit.

When the ViewSonic VE510 was first connected to the host PC it went through an automatic setup which resulted in a very impressive configuration needing little tweaking to improve it.

The video playback was very impressive with excellent depth of field and contrast ratio. The blacks were very black while not affecting the overall image. There was virtually little if any tearing however we did notice some pixellation in the fast scenes.

Overall the ViewSonic is quite an attractive monitor and performs quite well, but again it has no DVI input, no swivel base, and no speakers.

The integrated cable could also be a headache for some, however the slim bezel makes this monitor ideal for users of systems with multiple displays. The base is also not removable however it does fold up to allow for wall mounting.

We used DisplayMate for windows video edition to adjust each model according to the application's instructions and patterns. Once setup was completed we looked at subjective image samples, movie clips, and patterns to get a feel for the image quality and clarity. Our test rig stayed the same for all units comprising of a 2.6GHz Intel Pentium 4 system with 512MB RAM, 80GB HDD unit, and a 128MB Radeon video card with both digital and analogue outputs. In all the tests we used the 15pin D-SUB VGA connection to the monitor; the only monitor with both analogue and digital inputs in this review was the Philips 150B.

Final words
Well it seems they can only keep falling in price -- all the units in this review are easily within the reach of the average desktop user, and with the space saving as well as the power saving there are many benefits in replacing CRTs with LCDs on your next desktop rollout.

Look out for...

  • Image quality is going to make a big difference to your everyday use of the monitor. Look for sharpness of text, refresh rate, and contrast ratio.
  • Scrutinise the vendor's dead/bright pixel policy to ensure that if the worse case happens you will have support from the manufacturer.
  • Features such as in-built speakers, the ability to rotate the screen from portrait to landscape, extra inputs such as DVI, S-Video, composite RCA etc, or widescreen format. Some of these features are hard to find on the more entry-level monitors as tested in this review, however it is something to keep in mind.
  • Aesthetics in the office are becoming a important fact of life especially in professional environments, so the monitor's style is another issue to take into account.

Editor's Choice: Philips 150B
This month's pick is the Philips 150B 15-inch LCD Monitor. It not only has the most features of the monitors in this review, it also performs very well, has excellent design features such as the height adjustable base, and is well constructed but still stylishly attractive. The only downside is unfortunately the price as it is a little on the high side.
