Can my HD 6550D2 graphics card handle my new Philips B272B monitor?

not sure what you mean that your graphics card's connectors are blocked from the outside. If you can use your smartphone to take a pic, that would be helpful

Oh, I'm not sure if that is even relevant to my problem. But here it is (attachment).

also can you post the status of your drivers by posting whatever is in the right-hand side of the display when you do start > run > msinfo32 > components > problem devices. If all your drivers are working fine, the right-hand side (which shows problem device detail) should be blank.

It's blank.

I also tried the driveridentifier method (yes, I saw how it's done... watch where the drivers are unzipped, then use "browse", then use "let me pick"), but none of those drivers are accepted on my computer.

So you have internal motherboard graphics that you are using, and also a graphics card that is blocked off.

For the graphics card, I would remove the screws on the dvi port and remove the plastic covering the hdmi port on the graphics card, and giving each port a go. It could be that acer has built you a higher model x3470 but by covering those ports, sold it to you at a lower price so they could call it a lesser model. To try these ports, you will need to be sure there is no monitor plugged into the motherboard graphics ports, because when the system starts to boot if it detects something plugged into the motherboard graphics ports, the graphics card ports will be de-activated. Its uncommon for a system to be able to simultaneously use a graphics card alongside internal motherboard graphics.

we see from note 1 that the x3470 graphics specifications (resolutions?) vary by model.

The previous generation of amd motherboard graphics had a special dongle that had an ATI label and it was made specifically for amd in order to provide hdmi 1.4 functionality. Without that dongle you would get hdmi 1.0 resolutions (1920 max). AMD advertised those ports as "HDMI 1.4 via dongle". I'm not saying that's for sure the issue with your motherboard hdmi port, but it makes me suspicious.
