Blu Ray vs DVD Resolution

[kwong02]

Hi I've got a few question to ask that I came across yesterday.

1: Do I need a blu ray ready monitor to watch blu ray videos or does all HDMI monitor supports it?
2: According to wikipedia DVD disc can only support up to 480p or is it only the DVD player?
3: If I put a 1080p video file onto a DVD disc would it be downscale when I watch it using a DVD drive on the desktop?
4: Would it make a difference if I put the video file onto a memory stick and watch it using the USB port?
5: If I use a DVD disc (4.7GB) to store a 1080p video and copy and paste onto the desktop and watch it from there would there be any difference in terms of resolution?

Thanks in advance

1 It probably depends on the player. An HDMI device doesn't have to support 1080p. If your bluray player only outputs 1080p, then you may have a problem.
2 Video DVD is 480p. Some DVD players will upsample the DVD to 1080i or 1080p but the source material is only 480p.
3 A data DVD isn't limited to the 480p.
4 Same as above -- data file devices not the same as video
5 Moving a file off a DVD won't change it.

Wow, I am so mind blown by this for some reason.

If I buy an internal blu ray drive for my desktop the output resolution will be determined by the graphics card and the monitor correct?

What do you mean by data DVD? what is the differences between a DVD which contains video files and a normal movie DVD?

Also by upsample a 480p video to 1080p does that mean it is not actually true full HD?

Does that mean if I watch a blu ray disc it will be a true 1080p video because the original resolution is 1080p and not upsample from 480p?

Thanks so much by the way.

If you buy an internal bluray player for your desktop your output is determined by (probably) four things

• 
  ■ Software used
  ■ Graphics card used
  ■ Display resolution
  ■ Support for HDCP on ALL stages of processing If you try to display a bluray on a monitor via a VGA cable, even though it might be able to do 1080p, you will be prohibited from outputting 1080p. That is part of the high def copy protection. The interface between the graphics card and the monitor does not support HDCP.

Upsampled video is not true 1080p because it started with lower resolution source material.
If you watch a bluray (on approved hardware, and with copy protection approved software, via a HDCP interface to an HDCP compliant device) then it will be true 1080p.
