Can't get 1080i on my Philips TV

[Meph1st0]

I'm a bit confused. I'm seeing in the forums that some of the people here have the same video card as I do and they're able to acheive 1920x1080 resolution. I'm wondering if they're getting this picture on a TV that requires an HDCP compatible video card.

Here's my setup:

p4 2.4ghz, 1 gig RAM, ATI Radeon 9800 Pro w/ 128 MB RAM.

I'm plugging into a Philips 42 inch plasma via the HDMI port. If I try setting the resolution at 1920x1080 I get a black screen and have to reboot before I can get a picture again at 1024x768.

Is my TV requiring that my video card be HDCP compliant? I'm not trying to watch HD-DVDs or Blu-Ray discs yet. All I want is to be able to get over the air HD at my TV's native resolution.

Can anyone tell me what I'm doing wrong?

What resolutions does your TV support?

What is your model of TV?

If your native resultion would be 1920*1080 you'd be happy to have a 1080p television rather then a 1080i-capable one. i'm pretty sure your native solution is @max 136(6/0)*786px. since you happen to have a plasma rather than a LCD i'm afraid your native resolution is more likely to be 1024*768. this is pretty common for plasmas (unfortunatly) plus: your display starts with this one, and usually display devices are feeded with their native resultions by windows.

Okay, so, here's the skinny. I just found the manual (after a great deal of effort) and have the following info. The model number is a philips 42PF9630A/37.

__________________________________________________ _______________
The HDMI IN connectors allow the following TV and monitor display
modes:

HD Standard Definition TV (SDTV) 640/720 x 480i
Enhanced Definition TV (EDTV) 640/720 x 480p
High Definition TV (HDTV) 1920x1080i
1280x720p

PC VGA 640x480 60 Hz
SVGA 800x600 60 Hz
XGA 1280x768 60 Hz

Notes:
- If necessary, you can adjust the picture position to the center of the screen with
the cursor keys.

- Due to legal requirements, it is possible that with certain copy protected PCM
audio qualities from a device connected to the HDMI input, the DIGITAL
AUDIO OUTPUT signal is muted.

- Your TV supports HDCP (High-bandwidth Digital Content Protection). This is a
system for protecting DVD content outputted via DVI from being copied. It
provides a secure digital link between a video source (DVD, PC, etc.) and your TV.
Content is encrypted at the source device to prevent unauthorized copies from
being made.

- Proper working is only guaranteed with HDMI compliant consumer products.

- Digital devices from different manufacturers have the possibility of differing
output standards which may cause difficulties for the television to properly
display.

- In case no signal is detected from your HDMI device, turn off the HDMI device
and then on again.

To get an optimal viewing, it is advised to turn your DVD player to one of the
following TV display standards: 1920x1080i, 1280x720p, 720x480i or
720x480p.

so...does this mean I gotta set my computer resolution to 1280 x 768 to get the best picture possible? Also, I got another random question. How do I find out how much overscan my tv has? The TV does kind of a funky little thing whenever I've got a computer connected to the HDMI port. The screen appears to constantly readjust itself. Shifting left or right one column at a time and sometimes shifts so far in one direction that I start to see a weird green line appear on the edge. Is this normal? I'm thinking that if I set it to it's native resolution it won't think that it needs to readjust itself.

Oh, and here's another thing. In ATI Catalyst Control Center it has an HDTV section, in that section it shows detected panel information. It says it detects that it's connected to a Philips FTV with a maximum reported resolution of 1920x1080 at 60 hz.

But again, to repeat myself, if I try to set it at that res I get a black blank screen.

According to the data sheet for your Philips TV, it is a:-

42" High-definition plasma WXGA display, 1024 x 768p resolution

so it would seem that there is nothing to be gained by using a higher resolution from your video card than 1024 x 768 - which is the native resolution of the display. And this probably explains why you are getting a black screen at higher resolutions?

Yup
1024 x 768p is the best choice for you... (don't be too sad, al will still look amazing at that quality!)
