Simple question, why is my screen all that blurry? I mean it is set to 1680x1050 @ 60 Hz on 1080i with a DVI - HDMI cable which is 3 m long. The Screen is a 22" HDTV (NX2240w)
My GFX card is ATi HD 3650 512mb
Any suggestions?

Don't run it at 1080i.

This is exactly what has been going on through the entire thread, and it's not the first time either.
You come to us for advice..you just spell out what you want to get, and then ask us if it is okay, and we have to explain why it isn't. That's the world upside down.. If you would just say 'hey guys, I have an X amount of money, what should I buy?' Then this would be over in 2-3 posts, not 2-3 pages.

1080i means that the resolution of the picture is 1920 vertical pixels by 1080 horizontal pixels and i stands for interlaced scanning. ...
So even though your PC setting is at 1680, it's sending at 1920.
That's why it's blurred.
If the monitor has a DVI / VGA input you should be using that, HDMI accepts HD resolutions - 720p, 1080i/p etc. not 1680 x 1050.

Yes, but the problem is that when I change it to 720p the resolution is too low. It can't go up to 1680x1050 which it could with the VGA.
ok well when I change the resolution to 1920x1080 it's still blurred and not as sharp as with VGA maybe it's because it is running at 30 hz entwined.

Then you need to use DVI / VGA or it'll be blurred.

Ah, should've known it doesn't run 1680*1050..it's a TV.
I'd opt for VGA then, but I understand it sucks you can't run Audio to your TV except for a seperate cable.

If you set your PC resolution to 1280 x 720 and set the HDMI to 720p and then also try setting your PC resolution to 1920 x 1080 and HDMI to 1080p. Won't be perfect but may be better than the blur you have at the moment. The problem with those resolutions is that it's not your native screen size or ratio. Those HD resolutions at 16:9 and 1680x1050 is 16:10, so it'll be squished or stretched somewhat (cba working out which )

If you set your PC resolution to 1280 x 720 and set the HDMI to 720p and then also play with the GPU scaling in Catalyst control Centre you'll get a sharp picture..with black bars

Sorry, I copy pasted the first of my post 
Basically, you can set your TV to either 720p or 1080i mode right? Set it to the first is what I mean

I can't SET the TV to anything as I don't have any options for that. I can't even use Auto Adjust.

I have a sort of related question, I bought a new monitor, and it just so happens that the monitor has an HDMI port and a 1:1 aspect ratio. I know I'll obviously be able to watch things in full 1080p HD, but if I wanted to play a ps3 on the monitor (most games are 720p), could I get the 720p with no stretching or distortion? Like could I just change the resolution the match with 720p, and because of the 1:1 pixel mapping, will I be ok? If not, how bad do you imagine the stretching will be?
Thanks
Thanks

i HIGHLY doubt your monitor has a 1:1 aspect ratio - if it does, please link! id love to see it
if you will be able to watch 1080p HD, ill assume this is a 1920x1200 widescreen monitor (in which case, the aspect ratio is 16:10, not 1:1) - unless, of course, you got a 2560x1600 30'', which is the only other possibility
in any case, 1280x720p (which is 16:9) would most likely not stretch, but instead letterbox the top and bottom slightly. if it did stretch, it would only be 11% vertical stretch, which wouldnt be too bad

Hmm, well I'm not really concerned about the aspect ratio anyhow, but this is my monitor:
http://www.ncix.com/products/index.php?sku...anufacture=BENQ
I didn't see 1:1 mapping anywhere in the specs, but a bunch of the commenters said that it infact had 1:1 pixel mapping, and I saw information supporting this on a quick google search.

the TV's firmware (yes, it is a TV) most likely assumes the vga is the "PC" connection, and thus maps directly for that resolution, up to 1680x1050. the HDMI inputs, id wager, are directly routed through a conversion chip - and a cheap one at that
converting, unless the pixel ratio is an integer value, always forces the calculation to use averages between the chroma and luma of adjacent pixels, which (unless your TV has a very expensive set of chips, or you use a dedicated video processor to convert) always causes blurring and loss of quality
keeping all of this in mind, especially the fact that it is a TV, id suggest using your graphics driver's TV-out setting (as opposed to monitor) when using HDMI, letting the video card scale the image instead of the screen. its worth a try
