Does anyone think PS3 will support VGA?

When I play games in 1280x720 on my monitor, assuming that scaling is disabled, my games come out with black bars.

thats great!
how to ensure that the Scaling is disabled? its in-game option or monitor (cant see nothing like that in mine, iiyama Pro410) ?

"scaling" implies that he's using a fixed pixel display, in other words, an LCD monitor.
In your case (CRT monitor), you can always reduce the vertical size until the correct aspect ratio is achieved. The "black bars" in this case are the areas of the screen where the electron beam no longer scans across.

On a side note, AFAIK progressive HDTV formats only go up to 60Hz. Some (most?) people complain of perceivable flickering at that refresh rate on CRT monitors.

I can't believe that, after all that's been said and clarified on here, especially by yours truly, people are still going on about how HDMI can't handle 1080p at 60Hz, while saying that VGA can!!

I hope they support VGA, that would be sweet!

i thought if i try to play a console game at 720p in my monitor, it would show 16:9 black boxes on top and bottom. i guess not...

CRTs have no concept of aspect ratios at all. Theoretically, an analog signal has infinite resolution horizontally (assuming infinite signal bandwidth and no noise). Simply put, the CRT would be unable to differentiate between a 16:9 720P screen mode and a standard 4:3 720 lines tall screen mode, and would adjust both of them to cover as much as possible of the screen vertically, leading to a squashed 16:9 screen where people look very thin in their face.

LCD and other discrete pixel technologies sample the analog input signal and convert it to a digital signal instead. They can thusly figure out the screen resolution and could at least theoretically be able to differentiate between different aspect ratio screens. It would be up to the monitor itself to actually do it though, some might automatically scale all video to fit the screen fully anyway.

Humm... Pardon?

Driver option. Even if you have a CRT though, it may be possible to create a custom resolution where the driver will just border the image for you.

For my geforce card, I go into it's driver properties page, and then can add one under the screen resolutions and refresh rates tab. Then I just added it in and it works fine. If you're using a CRT, you should be manually able to adjust the image settings even if it messes up the aspect ratio.

BTW, Halflife 2 may also have native support for 16:9, I'm not sure it will give you the 16:9 option unless 1280x720 is reported as a valid resolution by your driver though.

Single link DVI has a bandwidth limit of 165MHz. The VESA monitor timing standard states that a 1600x1200@60Hz display has a pixel rate of 162MHz. That's probably the origin of this misconception. The closest VESA timing to 1080p is "W-UXGA" 1920x1200@60Hz. DVI can handle this resolution only by using the newer "reduced blanking" timing specification. OTOH, VGA has no specific bandwidth limit, by virtue of being analog. What that means is its bandwidth is limited by properties such as cable conductivity, transmission line termination, cable length, and other stuff that makes analog a black art.

1920x1080 requires 8% more bandwidth than 1600x1200, if 1600x1200 requires 162Mhz then the increase to 165Mhz just isn't enough bandwidth for 1080p.

The 162MHz requirement was for the "old" timing specifications, which catered for CRT monitors. In this case the 162MHz includes a significant amount of "blanking time" to allow the electron beam to zig-zag across the display area. DVI connection are predominantly for LCD (or similiarly "digital" displays such as DLP, plasma, OLED, etc.) which have no need for such lengthy blanking periods. Hence, VESA came up with what's called the "Coordinated Video Timing" (CVT) standard which minimized the blanking period. Under these new timings, 1920x1080@60Hz now requires only 138.5MHz, and 1920x1200@60Hz takes 154MHz.

There's a handy Excel spreadsheet calculator available on the VESA site http://vesa.org/public/CVT/CVTd6r1.xls, which is how I got the numbers above.

I for one am not saying that. I'm just saying that the only current reasonably priced 1080p TV can't handle it. I think the $13K Sony Qualias can, but I think Sony is targetting a slightly larger market.

HDMI is fully capable of 1080p, but the current, just released 1080p TV's can only handle it through VGA.
