BenQ E2400HD Evaluation

Before we get to the charts comparing results with other LCDs, here's a closer look at the performance of the E2400HD. As usual, we have charts for color accuracy using Monaco Optix XR Pro and ColorEyes Display Pro with a DTP94 colorimeter, a 3D color gamut volume compared to the Adobe RGB 1998 standard, viewing angles, and input lag/pixel response time comparisons.




Overall color accuracy is good, with slightly better results than the E2200HD in several tests, but slightly worse results in a couple tests as well. This time, uncalibrated color accuracy is better under Monaco Optix than ColorEyes; in fact, the uncalibrated Optix result of 3.124 is extremely good compared to many other LCDs. Calibrated results have the E2400HD scoring just slightly better than that E2200HD in Optix XR, and just slightly worse in ColorEyes. However, the E2400HD does have one color that spikes above a Delta E of 3.0. Average dE after calibration of around 1.3 will be more than acceptable for most users.

Color gamut is slightly lower than the E2200HD and again nowhere near as high as some of the top displays. If you're an imaging professional using an expanded color space, a different LCD -- most likely one with an S-PVA or S-IPS panel -- would probably better serve you, but for the vast majority of users the E2400HD will be fine.


Here we see the standard characteristics of a TN panel, with viewing angles that are worse than S-PVA, MVA, and S-IPS panels. Plop yourself down in front of the display, however, and it's unlikely you will ever have problems with the viewing angle.



Comparing the E2400HD with the HP LP3065, results are virtually identical. Out of 20 sample pictures (after we eliminated those that didn't clearly show one time at the bottom on both displays) only two pictures didn't have the same time code. We used these two images as the lag samples, one showing the E2400HD 10ms ahead and the other 10ms behind. You can also see differences in pixel response times, with the first picture favoring the HP LP3065 and showing significant pixel lag on the E2400HD, while the second picture shows the opposite. The net result is that differences in screen refreshes and camera shutter speed create small variations, which is why we compare input lag using multiple image samples (taken using a 1/125s shutter speed). On average, the E2400HD matches the performance of the HP LP3065.

Our summary of the E2200HD said that it was our current favorite among 22" LCDs, but the E2400HD has to go up against stiffer competition. If you view a lot of 16:9 content, the E2400HD might be the better choice for a 24" LCD, and for the price there's still a lot to like. However, Acer for example makes several competing 24" LCDs that cost up to $50 less than the E2400HD. Since we haven't been able to test those in person, we don't know if color accuracy is comparable or not, leaving us to compare the E2400HD with more expensive 24" LCDs. For the price, the E2400HD is one of the cheapest 24" LCDs currently on the market, and it still offers very good performance characteristics. Just beware of the issues with support for non-native resolutions, and you will want a DVI or HDMI cable and perhaps a better base stand. Add in those options and suddenly the price advantage disappears, making it more difficult for us to give it a wholehearted recommendation. It competes well with many of the other 24" LCDs we've tested -- like the Gateway FHD2400 and the Samsung 2493HM -- but it's not really better and definitely has a lower color gamut.

    If the last MVA panel from BenQ/AUO is any indicator, input lag should be low. I had the FP241VW with December 2007 firmware and it was 7.9ms behind a CRT, with only 5% of the time it being 2 frames behind. The other times it was only 1 frame behind, or none at all.

    It's good to see that our crying over on another forum has kept BenQ and AUO from abandoning the non-TN market altogether

    The only tiny issue with it was dark greys shifted more than (say) my Dell 2709W (S-PVA). Good luck with the review.

    Did you check the Samsung T220P? looks that have the same specs as the Benq. Seems to be a very interesting competitor as well.
    I would appreciate to read your comments about it.

    Looks like that was an Asian release only? I'm not sure... spec-wise, it's actually a 1920x1200 LCD, and I haven't seen any of those in 22" trim over here in the US. Weird. Honestly, I wouldn't be surprised if Samsung makes the panel in the BenQ LCDs; then again, it's either Samsung, AU Optronics, or Chi-Mei so I have a 33% chance of guessing right. ;-)

    Thanks :-) In Israel the Samsung T220P is available, and we belongs to Asia.
    Good luck with the new president! No matter who will be I wish you the best.

    [quote]We are only aware of one other 22" LCD manufacturer that offers native 1080P support (ViewSonic), and we feel this is an untapped market.[/quote]

    Check out Dell's new 2209W, it is a Full HD 22" LCD

    I edited the conclusion for you - I should have known better than to make an assumption without a bit more research. Probably HP has a similar display too - or it's in the works. Obviously, where one LCD company goes plenty will follow, and if there aren't more 22" 1080P LCDs right now I expect that to change. The Dell 2209W appears to lack HDMI input, however, so that's a big advantage for the BenQ and ViewSonic options IMO.

    True enough, I was surprised that they didn't have the same amount of inputs that many of their existing monitors already have.

    Wasn't looking for an update to the article, just wanted to send it your way in case you were looking for more monitors to review. :) Thanks jared, good information in the review.

    Probably all use the same LCD panel - once the panel becomes available, the usual suspects will all build a display around it.

    I know I want to step up to 1920x1200 or 1920x1080 so that means a 24" monitor. They seem to be the sweet spot right now as you can get a video card these days to run those resolutions in almost every game for a very reasonable price. However, there's no reason for me to upgrade my HD3850 until I get a bigger monitor since it runs all games just fine at 1440x900. I'm sure there are many other folks out there that are in the same boat.

    Now, it's easy to figure out comparatively which video card to get by reading Anandtech and other such sites but harder to find info on 24" monitors. Not too hard to compare FPS in a certain resolution and find a video card to get the best bang for your buck. However, for a guy that is a gamer, movie watcher, internet browser, and avid Photoshop user what monitor is the best bang for the buck. I don't want to sacrifice panel speed for colors. My idea with colors and Photoshop is just get me "close enough" and I'll be happy. I'm also on a budget (that's why I'm not looking at 30" monitors). Where is the happy medium here guys? -Thanks

    I have a BenQ MVA panel up next for review, along with a couple other 24" LCDs. I'm going to be very interested to see if the MVA panel can offer colors and viewing angles equal to S-PVA but with processing lag equal to S-IPS/TN. Stay tuned....
