Hi all,

I am looking at buying this monitor: http://www.ascent.co.nz/productspecification.aspx?ItemID=394027 and I am perplexed by the description "LED monitor". Does it mean the backlight is powered by LED? Any advantages / disadvantages behind that? Thanks

Cheers :)

Lower power consumption. Better contrast ration.

And in theory it should last a few years longer...

Also, IMO - that monitor is no good. The resolution is way too low for 18.5", that's the resolution I use on my 13.3" laptop.
Go for a bigger monitor with a resolution of 1920x1080, you won't regret it.

And some (dont know if all), are mercury free. LED may mean its still an LCD, but it uses an LED backlight

Cato: I plan to connect that monitor to a USB port on my laptop via a USB-to-VGA port. I am not sure if a higher resolution can be supported in the first place.

Your laptop does not have VGA or even HDIM output?
Weird.

I'm pretty sure VGA won't work for 1920x1080.

But perhaps this might help: http://www.wirednz.co.nz/video/90-atlona-usb-to-hdmi-converter

Well you wont get 1920x1080 with that monitor. Since, it only goes to 1366x768

And according to the Viewsonic site it says:

VGA up to 1366768 Non Interlaced

Apologies, I should have explained the situation better.

At the moment I have got a dual-screen setup whereby my laptop screen serves as the primary display while an LCD monitor (which is connected to the laptop via the VGA port) provides a secondary display. I am thinking of adding a third screen to the current setup, and the only way this can be done is to provide another VGA output via a USB port.

Both the laptop and the current LCD monitor are running at a resolution of 1366 * 768, which is the maximum resolution that can be achieved. If I get a higher resolution monitor, the icon and text sizes would look different from the other two screens.

Cheers :)

[Edit] Feel free to recommend an alternative LCD monitor that you think I should get. As long as it costs less than $190, I am fine with that.

I dont think it'll matter what monitor you get (if you want 1920x1080).

You maybe lucky to get one under $200. And VGA probably wont go to 1920x1080 anyway. And you may not get 1920x1080, unless the monitor's 20' +

So, do you still want LED? Or LCD?

You could get this (http://www.ascent.co.nz/productspecification.aspx?ItemID=388415) but I dont think its got VGA. Its DVI

It may also depend on WHAT resolutions the adapter supports, on what you can get

Maybe you won't get 1920x1080 but you would get 1600x900.

I don't agree with that.

IMO, there's no real difference (the fonts look slightly different due to them being different fonts).

The VGA on your laptop will support 25x16, why not just get a big LCD and do away with the laptop LCD?

Hi Renmoo, not sure why everyone is going on about VGA and screen resolution when it wasnt the question.

As you already have one LCD at 1366x768 and are happy with it, the viewsonic you have selected should be a suitable choice.
As already mentioned as LED LCD screen with have lower power consumption, it will have better contrast and colour - whites are whiter on an LED LCD. Often an LED LCD screen will have a slower refresh rate, however this wont effect you unless you use it for gaming and then you might not even notice it (Many LED LCD monitors have a 5ms refresh rate versus a 2ms or even 1ms).

My only concern and something you need to research if you havent already is make sure your USB/VGA display adapter will support that resolution such as the Digitus (http://www.ascent.co.nz/productspecification.aspx?ItemID=389045) solution.
Hope that helps.
Cheers

I prefer the idea of having three screen spaces as opposed to having one giant screen and a regular screen.

If it says LED monitor it typically means an LCD monitor with LED backlight (instead of a CCFL backlight)

However some monitors\TVs use OLED screens, but if it's using that they'll be sure to tell you. Loudly.
