Benq G2420HDBL or Dell ST2410?

miceormen · 15 Jan 2010 at 00:55

As per the title really. I want a quality 24" screen after some deliberation on here.. Both seem pretty bargainous, I'm not worried about hdmi either way, so long as its hdcp compliant (I can't afford a flippin ps3 - nor would i want one - how the heck you play cod6 with a pad is beyond my understanding)

What are the main advantages of the led lighting on the Benq? Will it just be the same story as all other tn panels where the light ultimately needs turning down in order to avoid headaches anyway?

And as ever worried about dead pixels.. Is this a common occurence or just something thats guaranteed to happen to some poor schmuck?

Interested to see peoples thoughts on this too

It will be the same story.

The main advantage with LED backlighting is lower powerconsumption. However, recent CCFL:s use so little power that the advantage here is minimal. The max powerconsumption for G2420HDBL is 24W. The max powerconsumption for ST2410 is 30W. So for personal use this isnt really what should be crucial.

Another advantage with LED is that it makes it possible to produce thinner LCD:s. The G2420HDBL use the same shell as the CCFL-monitor G2420HD though so I would think that ST2410 i thinner because it is a later model than G2420HD.

One advantage with G2420HDBL compared to ST2410 isa that it has a VESA stand so if you want it on the wall you should go with that one.

I've just ordered the G2420HDB. I was also considering the Dell ST2410 and the two reasons I went for the BenQ were the VESA mount as Trana mentions (essential for me), as well as the fact that it's slightly cheaper. I also fancied seeing what the LED backlighting does for the image, if anything.

It's coming on Monday so I'll put up some pics and a review on Monday night.

Brilliant, it'd much appreciated : )

Could you pm me where you managed to find one?

No need, it was OcUK

. Best price I found. Look north east of here ^^

It doesn't have LED backlighting though that's the G2420HDBL

I did wonder why he'd added a 'b' but omitted the 'l' to the suffix. Anyone who successfully acquires an LED version, i.e. the G2420HDBL could they be so kind as to put some pictures and thoughts up on here. Thankyou!

LED-lit panels also have better blacks as they can actually achieve it properly. CCFLs have their on-state as white, to achieve black the light is simply blocked rather than turned off, which is never going to be 100%. With LED panels they can literally turn off the pixel to achieve a true black.

How big this effect will be though is completely dependent on how well made the LCD is to be honest.

Woops silly me. Looks like we're getting the normal version then, oh well!

Its a gamble, although most people (A very large amount)are very lucky with it. Most monitors are checked by the manufacturer before shipping and they generally will pull units that are defect and recycle them rather than shipping them out. Depending on manufacturer.

Most monitors of this price are ISO13406-2 standard for deal pixels, which basically means they will allow up to 2 dead/burned or 5 stuck pixels per 1,000,000 before you can RMA them for that reason.

How many million pixels are we talking per screen?

I'm sure there's some highly logical calculation as per the resolution at this point that would point to an obvious answer but I know I can fall back on the trusted expertise of people who spend even more time in their chairs than I do

NathanT · 16 Jan 2010 at 17:18

Heh, don't know about spending more time on my chair.. but number of pixels is calculated by the NATIVE resolution.

When you look at screens and get the numbers : 1280 x 1024 or 1900 x 1080 for example it is exactly that. the height in pixels and the width in pixels

So a standard HD 24inch screen is 1900 multiplied by 1080 which equals 2052000 pixels.

Each manufacturer has its own pixel policy, some tend to be better than others.. and more than often the chances or dead/lazy pixels is reduced with the more expensive the unit.
Some retailers (for a charge) will dead pixel test a monitor before shipping it to you. As far as I know Overclockers don't offer this service, but if your that worried it may be worth asking.

just read this myself from this post here: http://forums.overclockers.co.uk/showthread.php?t=17772691

Apparently, ordering a TFT (or any product when not face to face with the salesman) you have a 7 day cooling off period with the retailer under the Distance Selling Act ( http://www.oft.gov.uk/shared_oft/business_leaflets/general/oft698.pdf ). As long as you cover the costs to send the item back to where you got it (as long as its re-packaged as you received it and no damage has been issues to the item whilst in your care), the retailer will have to offer you an exchange or refund. I'd do a little bit more homework in to this but this is the general gist (Although I'm sure there will be certain conditions)

Your confusing LED backlit monitors with true LED monitors, which as far as I know aren't available to the public, with Organic LED technology available, but being used mainly for smaller devices at the moment.

LED backlit monitors/tvs are simply LCDs, where the backlight is provided by LEDs rather than CCFLs.

I know, but I'm not getting it mixed up. The point is with LED-lit panels there is one white LED per pixel. If that pixel wants to be black, that single pixel can be switched off individually, and so a true black is achieved. Its because of the LED-lit tech that LCDs are no longer thought to be old tech to be replaced by OLED screens, using LEDs as backlights improves them to a similar level as OLEDs. Especially the RGB-LED backlights.

With CCFLs they use a series of horizontal tubes that are always on, as its tubes they can't be switched off for an individual pixel, so a true black can never be achieved.

And you can get OLED screens commercially. Some mobile phones use them.
