I have a 22 widescreen Acer LCD computer monitor that has 1680*1050 resolution. The monitor has a VGA and DVI-D inputs and also has/supports HDCP.
Yes and no. It won't be able to natively display 1080i or 1080p but it will probably downconvert it automatically for you. It should be able to display 720p just fine as it should auto-adjust to display that lower resolution.
That is what you want. It doesn't matter what kind of graphics card you have. You plug the single end into the back of your computer, and you plug your monitor into one slot on the double side, and get another VGA cable and run it from the other slot on the double side to your HDTV.
It all depends on the HDTV source. You can force the monitor to display 1080p but it may damage your monitor as it is a resolution that it does not support. It can display 780i/p though with no problem. This does not mean it can display all types of HD content. HDCP or High-Definition Content Protection is not regulated and is in no way standardized between different hardware components and various HD media. A Montior or graphics card can be HDCP certified because it has the little extra piece of on board hardware that allows it to accept and translate the copy protection but since each company has their own why of doing it, it does not work 100% of the time. you will run into this most often with things like HD DVDs or Blue-rays. Now, HD sources like XBL are set up to work for as many people as possible. When the 360 launched HDMI was not the standard, Component was, and that is why the 360 came with component cables and not HDMI, until recently. Xbox offered an alternative for people who may be using wide screen monitors and you can buy a VGA cable for a 360 and watch 720p movies downloaded from XBL using your monitor. I have an Acer P221w and use the DVI port for my comptuer and the VGA port for my 360. Only draw back is the 360 maxes out at 1280x1024 for it's resolutions using the VGA cable so I can not play my games and the highest detail my monitor supports, 1680x1050 just like your's But since 1024 is greater then 720, the HD content from XBL plays at full resolution with out issue. I do not own the HD DVD player for 360 so I do not know if it will work with you monitor, but since Xbox uses the VGA plug as an available output I would assume they are designed to work together. If you were to try and connect an HDTV cable box to your monitor using a HDMI to DVI adapter it may or may not work. Again, your monitor is not meant to display 1080p signals so you would have to some how make sure the signal from the HD box is only running at 720p.
