Acer Updates it’s 3D-capable Laptops with the New Aspire 5740D 3D

March 2nd, 2010 · 15 Comments · General 3D News


It seems that Acer is finally going to address one of the issues they had on their first Acer Aspire 3D-capable laptop – the 5738DG by releasing an updated 3D laptop. The new Acer Aspire 5740D 3D laptop comes with a set of updated hardware, including the most important thing – the video card as the first model was somewhat lacking in that area. Acer Aspire 5740D 3D will be available in different models equipped with Intel Core i3, i5 and even i7 processors and will use ATI’s Mobility Radeon HD 5650 GPU that is much better suited for stereoscopic 3D gaming than the previously used Mobility Radeon 4570. The screen will remain 15.6″ with a resolution of 1366×768 pixels and LED backlight with overlayed passive polarization filter to enable the usage with passive polarized 3D glasses. The new laptop is also going to use DDD’s TriDef software solution to enable stereoscopic 3D support for for 3D games, 3D movies and 3D photos on the laptop. This means that as with the previous first generation laptops when you are using the display in 3D mode by wearing the polarized glasses you’ll be getting half of the horizontal resolution of the screen per eye. Something that may bring some issues with multimedia that uses a lot of small details like for example tiny texts that need to be easily read as with half the horizontal resolution on the 1366×768 screen this might become somewhat of a challenge for you. Anyway, it seems that Acer is moving on the right track with this upgraded model and maybe their next line of 3D-ready laptops will feature a 120Hz LCD screen and come with 3D Vision shutter glasses just like what Asus did with their G51J 3D gaming laptop.

Asus Republic of Gamers G51J-3D Gaming Laptop Short Review

February 16th, 2010 · 8 Comments · GeForce 3D Vision


Last week during a joint Asus and Nvidia event I was able to try for a bit the first laptop that has a built-in 120Hz LCD display and comes bundled with Nvidia’s 3D Vision shutter glasses – the Asus G51J-3D. This is actually the first gaming laptop that is intended for stereoscopic 3D gaming using the 3D Vision active shutter glasses, although you can still play in 2D mode at 120Hz without any problems if you wish to. I did not have much time to play with the laptop, but I’ve managed to test in a brief how good the laptop performs in stereo 3D mode, something that I suppose everyone else here is most interested in too. And I do hope to get the laptop for more extensive testing when it becomes available on the local market where I live to get more details and information on general performance and feedback on other features…



Asus did very well in designing a very nice and attractive looking laptop on the outside with an extensive set of features and quite powerful hardware inside. Along with the laptop you also get a nice bagpack to easily carry it everywhere with you along with all the additional accessories and these include not only the bundled 3D Vision glasses, but also a gaming mouse in the form of Razer Abyssus, so you can actually be ready for gaming on the go and in S3D too. Of course by gaming on the go I do not literally mean to play while traveling as the battery life you get won’t allow you to enjoy your 3D games for too long, it is more like you can easily move with the laptop and all the needed accessories along with it. So you can actually have a compact and mobile stereoscopic 3D solution to carry around with you and that does not only include use for gaming, but you can also enjoy stereo 3D videos and stereo 3D photos. The mobility factor is especially good if you shoot S3D photos and videos at different locations both as an amateur or professional and you need to check them out right away, but then again still not a lot of people do that and the Asus G51J-3D is mainly intended for gaming as I said.



A quick look at the most important specifications among which are the Core i7-720M processor (quad-core 1.6 – 2.8GHz) along with an Nvidia GeForce GTX260M (112 stream processors) video card with 1GB of DDR3 Video Memory. Other specifications are quite good, but these two are the most important components when we are considering if a laptop is good enough for gaming and then again if it can handle the additional load that is introduced when you are playing in stereo 3D mode. And considering what is “under the hood” of the Asus G51J-3D I can say that it offers really top performance for a 15-inch mobile gaming solution and will handle stereoscopic 3D gaming very well.



The display is 15.6-inch, 16:9 wide aspect ratio, with LED backlight and with resolution of 1366×768 (HD-ready) and not Full HD, something which you can actually consider to be a good choice. Although being one of the top video cards in the mobile segment the GeForce GTX260M can have some problems managing high framerates at Full HD resolution in some games, especially when you add the S3D in the formula, but for a resolution of 1366×768 everything is just fine. Moreover having a resolution of 1920×1080 pixels on a 15-inch laptop can bring some issues like things being too small on the screen etc., besides some performance issues in stereo 3D mode with some very demanding games, although it seems that Asus might offer another model with Full HD resolution. The LCD panel as I already said is a 120Hz one, but just like its desktop counterparts it can work in 60, 100, 110 and 120Hz refresh rate and you have the option to switch between the settings.



Checking the LCD panel it seems to be a bit brighter at the bottom part only which is actually very hard to notice by a normal person using the laptop when playing a game or working with something that does not include a completely black background. The uniformity of the backlight is better compared to quite a lot of other laptops, although not perfect, but for that also helps the usage of LED backlight instead of CCFLs. As you should know brightness is a very important factor when you play in stereo 3D mode as the active shutter glasses actually do block some of the light coming from the monitor and thus the image perceived is a bit darker than when not wearing the glasses and playing in 2D mode. Visually the level of brightness of the screen here is lower than what the desktop 120Hz displays are offering, this is to be expected from a laptop screen, but the brightness level was still Ok. And yo can resort to the brightness level adjustment from withing the options of games that do have darker atmosphere and you have trouble differentiating some details int he environment because of them seeming too dark.



The viewing angles of the screen are Ok and just about what you can expect from a mobile TN panel. The image is looking great for a single person using the laptop and considering this is a gaming laptop this is the most likely usage scenario, so you should not have trouble with that. But considering this is also a stereoscopic 3D capable laptop on which you may also want to look at 3D photos and 3D videos and that you might not be doing alone the lower viewing angles might be an issue. For two people sitting in front of the display and looking at the content being shown it is still Ok, but if you add a third person it might be so that only the one in the center will be seeing good image and the two on the sides might have trouble with seeing inverted colors on the display like on the picture above. Still as I said the viewing angles for a single person using the laptop everything is just fine with the viewing angles, for more people – you better go for at least a 3D-ready desktop display or start considering to get a 3D-capable HDTV this summer.



Top and bottom screen ghosting of objects when playing in stereoscopic 3D mode is here, as expected and as available on every other 120Hz monitor so far I’ve seen. It is not too much and it is easy to be ignored, you’ll very quickly learn to do that and it is not like that you’ll have much time looking for it while playing your favorite game. You should be just aware that this issue with the current generation of 120Hz LCD panels did not magically disappear on the screen used by the Asus laptop and you can expect to see it there too, just like on the desktop displays, including the second generation panels used by Acer and Alienware.



I was a bit surprised to see some colored ghosting effect similar to what I saw on the Acer GD245HQ display, but here it is less apparent and the colors are not so bright so you can much easily not notice it at all if you are not specifically looking for it. It seems that this issue is something available on the second generation 120Hz LCD panels and although it appears only from time to time if a specific conditions are met about the image shown on the screen it is stil there and you should be aware of it. Also it is more easily seen on the picture taken with the camera tough the lens of the shutter glasses than when you are looking with your eyes on the screen and much like the top/bottom ghosting it is something that you can easily learn to ignore and it is not like you’ll have much time to “enjoy” it while playing anyay.



I’ve left the Windows 7 Experience Index for last just to give you some idea on how Windows 7 rates the laptop and maybe if you want to compare with your laptop to see the difference. It is interesting to see that the overall rating is a bit low – 5.9, but that is because of the slow hard drives, all other results are higher and the performance is generally quite high, especially for a laptop. So I can conclude that Asus did quite well in providing us with the first mobile stereoscopic 3D solution that uses a 120Hz display and 3D Vision active shutter glasses. The system is well designed, powerful in terms of performance and offers some nice features… of course all this comes at a price, but if you need the mobility then the price should not matter for you. There are some minor drawbacks, but then again most of them are not uncommon for a laptop or for the new 120Hz panels in general, so I would lie if I said I did not expect to see them on the Asus. The only recommendation would be to stick to single person usage and not to try to have more people watching 3D movies or photos on the laptop as then the experience might not be the best for some of the viewers. Feel free to ask some additional questions as I might’ve missed writing something…
