HP DreamColor LP2480zx - 24in Professional LCD Monitor


Our Score:


Design doesn't end with aesthetics or ergonomics, however, since on a monitor such as this, configurability - and the ease to which it's done - is vital and here the HP really begins to excel. It helps that the control buttons are logically arranged. Running along the right-hand side their vertical alignment means they work intuitively with the on-screen display (OSD) menus. There's none of this irritating right to go up, left to go down malarkey, here.

Instead you're treated to a sensible set of six buttons: one for power, two to navigate menus and a further three that act as shortcuts for default functions or are context-sensitive when in the OSD. Shortcuts include the top one, which takes you directly to the colour space menu, below which sits a shortcut button to the input select menu. Next are the navigation controls and below these is the OSD shortcut button, which doubles as Select/Open when in the menu, with the power button a little further down. Best of all, however, is that when in use the context-sensitive function of each button appears next it on-screen. This, combined with the consistent and intuitive navigation, makes adjusting the myriad settings on the LP2408zx a breeze.

Myriad is an apt word to use, too, because anyone with a mind for tweaking and fine tuning could be buried in the LP2480zx's menus for hours. It helps, obviously, that commonly used colour spaces come pre-programmed for on-the-fly changes, but you can also pre-configure one colour space yourself. Beyond this there are plenty of vital settings you can configure, too. These include luminance ('brightness') at a maximum of 250cd/m2 to a minimum of 50cd/m2, as well as the white point (colour temperature) from 4,000K all the way up to 12,000K.

You can also adjust gamma and black levels independently, while scaling options are comprehensive, allowing you to crop the picture, scale while maintaining the aspect ratio and view a one-to-one pixel map - vital if dealing with a 16:9 source given the 16:10 resolution of the display. This is something we've had problems with on some monitors but on the LP2480zx, pictures are scaled - or un-scaled as the case may be - perfectly.

In addition to the configuration options, the LP2480zw also boasts a wealth of additional management and information features. As with the outstanding LP2475w we reviewed last week, DDC/CI (Display Data Channel/Command Interface) support is included, enabling software control of the monitor's variety of configuration options, as is EDID (Extended Display Identification Data) to inform the graphics card of the display's capabilities.

HP has also added a number of power management settings, including a 'power on recall' capability and the ability to set the display to turn itself on and off at specific times. Auto switching and detection of inputs is also supported, so you needn't always manually switch between inputs. Finally, as you would reasonably expect, the display monitors and reports both the number of hours since the last calibration, as well as the number of backlight hours.

"Now all HP need do is make a 30in version!"

No, now all they need to do is make one that's a tenth as expensive aimed at the general population.

However, hopefully all the technology in this HP will filter down to us consumers in a couple of years time. 10bit colour reproduction, and all the goodies on offer here, sound like something I'd like to upgrade to in a couple of years time, when the price is more sensible.

I mean 30-bit panel (when are TR going to introduce an edit function?).

Impressive. Imagine if the cost of cars came down from tens of thousands to 2k, it would be world changing - admittedly an environmental disaster, but still a revolution.

@YG the cost has come down to that ;) http://news.bbc.co.uk/2/hi/bus...

Thanks, Andy for a fascinating review of a fascinating product! I'm a heavy-duty graphics user and own an excellent 24" Eizo ColorEdge CG241W, still less than a year old -- but of course I love to read about progress in this field.

But I'd like to point out that your article seems to confuse *bit-depth* and *color gamut*. However, there is ZERO connection between these two phenomena: the color space a monitor can display (sRGB, Adobe RGB, etc.) is not in any way controlled or limited by bit-depth.

Also, 10-bits/channel sounds nice, yes -- however, we'd need a graphics card capable of outputting this, instead of the usual 8-bit/channel. So which cards would you recommend for this purpose? Years ago, Matrox made one, but since then I've heard nothing about 10-bits/channel graphics cards. If you know things I don't know -- I'll be happy to know about it! :-)

Great review. If my design career takes off I might pick one up.

A little off topic, but: It really bugs me when I see the 'percent of NTSC colour gamut' specs... this is useful for US-based video editors, but NTSC is pants for colour, PAL has more depth. We used to call it 'Never The Same Colour twice' because NTSC sets use tint control in an attempt to display more colours. Rant over.

@ Klaus

The ATI HD4800 series supports 30-bit depth over DVI and DisplayPort...not sure about NVIDIA cards, but the very common HD4850 is quite affordable at US$135 or less. Probably not what the owner of such a quality display has in mind (NV QuadroFXs and ATI FireGL/FirePros more likely, which also support 30-bit depth), but could most certainly afford.

I'm thinking a few of these would look great on my desktop, too bad one of them nearly costs more than my entire setup combined...

Sounds really nice...but this is professional level, which I think is out of most readers budget, including mine. It's nice to read about the cream of the crop, but I think there are far more potential buyers around the 24-27" market of between 𧶲-𧺬 mark. I'm talking selfishly about my own needs here though. It'd be so great to buy a ٠k monitor and never look back!

Klaus: Are most sRGB images not designed with 8-bit in mind? If that is the case then to display any wider gamut as well you'll need a higher bit-depth so you don't lose any of the colours the original image was intended to have.

@Pbryanw: Given that 24" 8-bit monitors are still 𧹈 I'm rather doubtful we'll see 10-bit 24" monitors at 𧶀 any time soon.
