Yes I'd get it replaced. Looks like it's been damaged somehow.
The BenQ EW2420: Too good to be true?
- Thread starter PCM2
- Start date
The colours are better on the EW2420 (slightly more vibrant and undoubtedly more accurate) and the contrast is hands down much, much better. The LED backlight also gives it a slight edge in efficiency and lower heat production, although the *VA panel does nullify this advantage somewhat. The responsiveness is the only area where the B2430H really has an advantage. The stand is possibly a little better on the Samsung too but the overall build quality is similar. The EW2420 does have a bit of extra weight to it. This is all covered on the review though.
If you haven't noticed backlight bleedthrough from your unit - for god's sake don't go looking for it! A lot of things are only a problem once you start noticing them.

Thanks for the heads up about the joined up words. I think you are very right about the quality variability of BenQ monitors. It is something I have observed with lots of monitors from all different manufacturers but the variability of 'cheaper' monitors such as BenQ and Hanns.G monitors seems even greater. At the higher end I have seen (or or at least heard about) considerable variability in higher end monitors such as the Dell UltraSharp series too. The more extreme variability is often from differences in the backlights themselves and not the panel - I'm hoping OLED monitors will show much better consistency due to the lack of backlight.

Go to 'Picture Advanced' and change 'Display Mode' to 'Full'. You may also need to adjust the overscan in the graphics driver.

That is a tough question. I assume you mean from an entertainment point of view? The EW2420 shows slightly greater vibrancy due partly to the semi-glossy panel. No question it is the superior panel for contrast. I would say for games and movies this gives the most pleasing image but this is quite subjective. The range of colours and accuracy of the colours is very good on the U2311H and it has a slight edge in terms of responsiveness. Considering everything though and including price my choice would be the EW2420 for entertainment but the U2311H for colour-critical work. Actually I would probably choose the U2410 over either of those for anything but that wasn't the question
.
Maybe right. I just use DVI on my EW2420 and it is all fine. Maybe you should use VGA in the meantime and order a DVI cable? HDMI seems to be by far the most problematic interface for PC users.
How did you gague the input lag is better on the u2311? They are both around 15ms i would say and you can't use that is a distinction. Given everything the BenQ is a better buy as an all-rounder. Considering the uneven whites, poor contrast and tinting that is being reported by many u2311h users I wouldn't take the gamble.

The biggest consideration is that the 2407WFP is broad gamut and the EW2420 is not. But as in that post the semi-gloss screen does add a greater level of vibrancy over other standard gamut screens.

It's 'full scale' release was intended, alongside the XL2410, to be later this month. Hopefully things will pick up.
The difference in input lag depends largely on who is testing it and how they are testing it. It isn't an absolute value - it is given relative to a CRT of the reviewers choice and there is no standard methodology for testing. As I've said the input lag is not a problem in either panel and the difference between them when you actually use them is not at all significant. I didn't mean the U2311H has poor contrast - far from it. As with everything else in the post it was relative to the EW2420. Again, the values for contrast vary considerably depending on the equipment and methodology used and the 'peak' contrast is sometimes achieved using settings that are terrible to use for gaming purposes. That isn't the case for the U2211H or U2311H though and contrast is impressively close to the stated values even under 'gaming' settings.
Really what this boils down to is how vibrant and immersive you like your gaming and movie experience to be. The explosions, flames, muzzle flashes etc. etc. and just colours in general are far more in your face on the EW2420, without looking over saturated. The U2211H showed excellent variation in shades and a good 'natural' look but it lacked a certain flair to the colours. The absolute distinction between 'light' and 'dark' that can help add that little bit extra to games and movies was missing. The EW2420 and U2410 both trump it in this department. You can gague what to expect by comparing our U2211H review with the EW2420 review if you haven't already.

Thanks for your thoughts. They are always welcome . It is good that you have a monitor that you are happy enough to want to keep for 8 years if you can. Haha. In a few years time we will have nice OLED monitors (check my signature link) that will hopefully iron out a lot of the problems that come from the backlight and how the monitor is sandwhiched together.

The ViewSonic VP2365wb is astonishing value really and is probably a good all-rounder. I haven't used the monitor myself but I see it as similar to the U2311H but marginally less responsive, perhaps comparable to the EW2420 if not a little better. It's one of the best-selling IPS monitors on my website. You are right - you don't want to be bogged down by a 1 year warranty with a monitor if you can help it. There's just so much to go wrong and in most cases a small fault impairs what you see on the screen.
4.3ms sounds quite wrong for any LCD monitor to be honest. Even 7ms is pushing it. But I wouldn't dwell on this figure too much. You can always exercise your rights under DSR no matter what monitor you get. Yes you have to pay for return postage but it could be worse.
Haha, if I bought every monitor I've been considering and sent them back under DSR, I'd probably lose about £500 just from postage
That's what's nice about being able to test out review samples first I suppose. Don't have to pay for these things.
Do you have AMA enabled? It doesn't sound like a fault. It sounds like what was described in my review as 'black ghosting' and is inherent to *VA monitors.
You say it wasn't that visible when you first got the monitor? Is it not because you have noticed it and now suddenly you keep on thinking about it and can't ignore it? Or has it actually suddenly got worse? Either way if it does bother you the Hanns.G made it in as our 'monitor of the month' this month ahead of the EW2420. Don't expect the contrast or colours to be anywhere near as good. But this is the sacrifice you must make at the moment for a good level of responsiveness.

What other FPS games have you been playing? Black Ops and some others perhaps? I actually found Bad Company 2 quite bad initially - I did comment on the loss of texture detail on my very first post on this thread. After having used the monitor more and more I found the overall experience just too good compared to other TN panels in this price range. I don't use it on my primary computer though so I don't have to 'put up with it' all the time. I didn't find the response time issues adversely affected my gaming performance though.
The grass becoming super saturated sounds very much like the 'smoke-like trail' you get on VA panels when greatly contrasting colours or shades move against one another. It does sound a bit exaggerated - you don't have Digital Vibrance enabled do you? What is your secondary monitor you have next to it?
You should turn digital vibrance off and see if this helps make this ghosting less apparent. I have mine connected to an ATI card (so no Digital Vibrance) and it looks excellent.
You'll have to read the review and this thread and judge for yourself. The V2420H is not a great monitor, frankly - it's more like a toy than a serious bit of kit.
I think it is clear from the review what my recommendation is, as905. The response time is the only thing letting it down. I have no trouble gaming on it and find it much better than most if not all other monitors in the pricerange due the the image quality. For some people the response time, TrTf in particular, is just too slow. If you really want a responsive BenQ you should be looking at the XL2410T, if you can find it, as it will cost around the same as the M2700HD when it's in full stock. We will be reviewing this next week.
