YouTube’s New Support for 4K Video Resolution Means Better Stereo 3D

July 11th, 2010 · 7 Comments · General 3D News

YouTube has officially announced that now they support upload and playback of videos with resolution of up to 4K (up 4096×2304 or 2304p and of course also 4096×2160/3840×2160 pixels or 2160p), and although this is not something that every normal user will be able to take advantage of at the current moment, it is still a good move. Actually the update of the supported resolution is more interesting move for people that are working with stereoscopic 3D video than to those that work with higher resolutions than Full HD 1080p (1920×1080). The reason for that being is that commercial cameras that offer recording in 4K 2D resolution like the RED Camera for example are quite expensive for a normal user to afford, but using two consumer grade Full HD cameras you can record stereo 3D video on the cheap and get it in Side by Side format with resolution of 3840×2160. Then you can upload the video in its full resolution and everyone will be able to watch it in its original intended quality in 3D, instead of having to rely on 1080p with half resolution, because of the image being squashed in order to fit into the old supported video format, although this mode will still be available for compatibility reasons with some 3D hardware.

So going to 4K video resolution is indeed a good news for all of us interested in stereo 3D, and in order to get the full quality of normal videos or stereoscopic ones that go beyond 1080p resolution you’ll just have to click on the Original mode when selecting the resolution. This will show the original resolution that the video uses if it is in more than 1080p and up to 2304p, no matter what the resolution is in between these supported modes. Just have in mind that watching 2D or stereo 3D video in 4K resolution online through the flash player requires higher bandwidth, faster CPU and preferably a good video card that can handle GPU acceleration to decode the content in real time. The new 4K support is referenced by the fmt=38 mode in YouTube and that is something that you just might be interested to know if you are interested a bit more into the internal workings of YouTube. What I would recommend to do if you want to actually watch these videos comfortable is to download them on your computer and then watch them, and that is a must if you want to watch stereo 3D videos with 3D Vision anyway.

What Happened With Asus’ VG242H 120Hz LCD Monitor?

December 30th, 2009 · 12 Comments · GeForce 3D Vision


Do you remember that earlier this year Asus has announced and shown a 23.6″ LCD display with Full HD resolution that was capable of working at 120Hz, and do you know what happened to it? Well, I don’t know either… and Asus had a working model of the VG242H available during COMPUTEX 2009 back in June, although it is still not available. Asus was expected to have the display available on the market by the end of the year, but it is still not here… and there is no word on when or even if it will be made available, not to mention that meanwhile the company missed their chance to be the first with a Full HD 3D-capable computer monitor. The reason for that is the announcement of The Acer Aspire GD245HQ 3D Vision-capable Monitor that has already started appearing on some Asian markets with soon to follow availability in other markets in January/February 2010.

Anyway, here are the known specifications for the Asus VG242H 120Hz:

Display size: 23.6″, 16:9 Widescreen
Panel Technology: TN (Twisted Nematic)
Resolution: 1920×1080 @ 120Hz
Contrast ratio: 20000:1 (Dynamic)
Brightness: 300 cd/m2
Response Time: 2ms (gray-to-gray)
Internal speakers: 2Wx2 Stereo
Connections: HDMI, DVI-D (Dual-Link), D-Sub, Audio-In Jack, S/PDIF Audio output, Earphone Jack

Acer Aspire GD235HZ will be Another 3D Vision-capable Monitor?

December 9th, 2009 · 2 Comments · GeForce 3D Vision


I’ve recently mentioned that Acer is going to release its first 120Hz gaming LCD display very soon – the Acer Aspire GD245HQ, which will be a 24-inch Full HD monitor (the first on the market with that size and features). You can see how the GD245HQ looks like on the image above, but it seems that Acer won’t be leaving things with just that 3D-ready display as there is info that the company is also preparing a bit smaller 23-inch (judging from the model number) version that will be called Acer Aspire GD235HZ. Unfortunately there is still no information regarding this new model, but I pretty much suspect that it will be based on the recently announced 23″ 120Hz Full HD LCD panels from LG that I’ve also mentioned and the specifications should be pretty much similar to the ones of the 24″ display. Still it is interesting to note that we are going to have more options in terms of size and resolution when we are considering what display to choose to build a gaming system with Nvidia’s 3D Vision active shutter glasses. Just don’t forget the fact that playing in stereoscopic 3D mode on 1920×1080 resolution will require a more powerful video card than for the currently available 22″ 120Hz LCDs with native resolution of 1680×1050 pixels. That is of course only if you want to play at the native resolution of the display (and who would not want that) with high details in the latest games and when you invest in a 3D Vision gaming PC you are most likely to want that, right?

On a side note, it seems that Acer has just started taking orders and producing the 24-inch Aspire GD245HQ monitors, meaning that there will be some delay with their availability (as I suspected) and they’ll actually be available on the market in January/February (depending on the country). As for me, I hope to have one of these displays available for testing as early as the beginning of February, but this is still not a sure thing…

Update: It seems that Acer Aspire GD235HZ won’t be using different hardware, but actually is the same monitor as the GD245HQ, just a different part number for another region!
