sceptre x22-wg aspect ratio issues

I'm very surprised this hasn't been mentioned anywhere I can find, and I've searched the internet quite thoroughly.

I have a X22-WG monitor that supports HDMI which I use for my PS3. However, the PS3 produces a 16x9 image so the monitor stretches this to accommodate for its 16x10 aspect ratio. How do I letterbox it, so I have a proper aspect ratio?

Anyone have this monitor that could help me out? Thanks.

Thanks for your response, but the issue has already been resolved.

The 16:9 image that's produced on a Sceptre monitor will always be stretched to be 16:10 so it can fit the full screen. I've e-mailed them, and they responded saying it's an error the Sceptre engineers just didn't even think about or notice. The "16:9" option on the monitor's menu is in fact not 16:9. While 4:3 is a proper aspect ratio on the monitor, any image that isn't 4:3 is still stretched.

I've gone to many forums and even though I see these tech gurus post pictures of their PS3s running on their Sceptre monitor with that stretched image, they never even mention it! Is it like commonly accepted or something? I find it annoying.

My question is: why even support HDMI if you're going to stretch all of the signals taken from it?

I'm going to try an HDMI --> DVI adapter with a digital audio and see if that makes a difference.
