Resolution - Very confused

MK2 · 10 Jun 2010

That's what I was thinking, better try it on DVI
Most times there is a DVI cable included with a new monitor, so should not be a problem.

I have the VH242H and using DVI from my GF9600GT, no text blur @ 1920x1080. I have my 360 hooked up to it via HDMI, no bluriness there.

hmm... where to find the missing 28 pixels? Can you tell us the model number of your monitor?

Asus 24" VH242H

Sorry - I have updated my profile now.

There may be some other neferious goings on when using the HDMI output which is meant to be connected to a TV. The radion may in fact be blurring the image on purpose so that it looks better on a television or something.

Use a DVI cable to the monitor and see if that makes any difference.

Brilliant - I have connected via the DVI-I cable and the image quality is crystal clear at 1920x1080 and fills up the complete screen without any black borders.

But now I am still really puzzled as I thought HDMI was the best possible connection to use. Could it be a fault of the HDMI connection of the graphics card?

Is the DVI-I connection actually High Definition?

Should I carry out any further checks?

Thanks for everyones help and I have now updated my profile.

DVI and HDMI are identical in terms of quality. They're both digital and the output will be high def as long as the input is. The only difference between the two cables is that HDMI also carries audio... so if you have a capable Radeon (geforce doesn't do audio yet) , you can use an HDMI directly to your TV.

However, if you use a stereo receiver, and not your tv's speakers, like I do with my htpc, you want to use a dvi - hdmi cable from the video card to the TV, and an optical cable, from the s/pdif to the stereo.

My "fear" with HDMI is that it was made to connect computers to "TVs". To replace the component or even the old S-Video jacks on graphics cards. SO there is every possibility that the output is handled differently on HDMI than the DVI because the card manufacturers are assuming two distinct roles for the connectors. This may vary by card.

Another possibility I suppose is that your HDMI cable is not very good and at certain frequencies has a lot of croisstalk or something...

But personally I would stick with DVI for any normal computer monitor and HDMI when hooking up to a TV.

Thanks for everyones help in resolving this problem. I may well use the HDMI to connect to my 32" LCD TV in the adjacent room. It will be interesting to see if I get the same problem.

The question that comes to mind is that the TV is 1080i. Will this mean that I will have to have different resolution settings and therefore not be able to "Clone" what is on the monitor to what is on the TV?
