DVI to HDMI converters

[jj]

I Have a full HD sony LCD telly.

Through the PC connector is  only support 1368 x 768 or something like that res.

If I used a DVI to HDMI converter whould my pc reconise the extra resoulution and would I be able to set my desktop on my pc to 1080p.

Are you sure you have a 1080p TV?

[jj]

To confirm I am talking about therough the analouge vga cable.  Taking to a few people in work seems this is the case with these.  And through a dvi to hdmi box on the grpahics card it does give the full HD

@ bloodline oh yes im sure

everything else, my xbox, dvd player etc is running at 1080p

in case you want to  check its a kdl-40w4000

so back to the original question.  does anyone know ?

From what I've heard about HDMI and DVI the video signal is very similar, which is why an adapter has been made.  I would guess that if you have an adapter, you could indeed set your resolution to 1920 by 1080.  Bear in mind though, you might be limited to 720p or 1080p only, so anything game or program that is set to a different resolution might not display properly or at all.

My telly supports a few other res over hdmi so should be ok, but I know what you mean.

To be honest, only want to use it for things that would open to desktop resolutions , like firefox, thurnderbird and open office.  Might play the odd rts in massive res might be fun.

Wouldnt want to play fps at 6ohz, no my telly does not have 100hz

I have Sony 2000w and it works 1080i, 720p, 576p, 800x600 comes out as 720p, and some still smaller modes, all via HDMI; 1080p probably doesn't work because of cheap and long cable.

Hi JJ,

It looks like the specs on Sony's site say it only allows 1080P over HDMI or Component, not over VGA. This would make sense as sending 1920x1080 over VGA would look quiet bad unless you had very well shielded and very short cables.

A DVI to HDMI cable should therefore work fine (as long as your graphics card can support that high resolution). And, because DVI is digital, you should get a perfect picture. What graphics card do you have driving that monster?

On the TV, you will also want to set the Display Area to "Full Pixel" so that the TV runs the panel without any overscan. This should give you the best picture quality.

Hi Mike

Already have my screen on full pixel  :-D

GPU should be fine its a 8600 gts 512mb  

I have a dvi to HD component converter sowhere off my old 850XT will give that a whirl for now.

As already using all my HDMI ports.

Im confused though why it wont do 1080P over a vga analouge connection, but will over a component analouge connection.

is it because of the cross talk over a vga cable where as component three seperate cables ?

[zipper]

My Sony instructions clearly state that the VGA output is max 1366x768.

[jj]

SO do mine.

But HD component ( whic his also analouge) supports 1080p

I was just wondering why the difference.

[AJCopland]

It should be capable of it but maybe they just decided not to support it, I used to use VGA for doing 1080p with my Xbox360 on my Dell 2407wfp because it didn't support 1080p over HD component (the reverse of your situation! though it would do 1080i.).

I think they just skimp and save on some internal components sometimes.

Must be for that reason. because you would think a vga cable carries a better picture/signal than three rca cables for the coomponent.

And as you say the xbox 360 supports 1080p over a vga connection.

HDMI has the DDC lines, so yes, your PC should recognize new resolutions. I'm using a DVI to HDMI adaptor and the graphics card instantly recognized that it was an HDMI connection.

If your TV can accept 1080P through the DVI/HDMI input, then it will display 1080P, otherwise it will display 1080i max.

Since you've got a 8600GTS, you'll have the Nvidia control panel from which to set up your output resolution.  Your TV should be automatically identified by the software.

One good reason for going the HDMI over VGA is that you can combine your audio.  If you've got onboard RealTEK audio with an SPDIF OUT header on the mobo, just connect the output to the SPDIF input on the graphics card and make the SPDIF settings in the RealTEK audio software: -

Sampling Frequency 96KHz or 192KHz

SPDIF output - Audio Device (not by-pass)

If you prefer to have 5.1 or WHY through co-ax/optical, then set the sampling rate to 44.1KHz or 48KHz.

If you're using PowerDVD, then set the audio output channels accordingly.
