Seriously not happy with this TV - any suggestions?

Okay, bought myself a 1080p 42" Clarity telly, as advertised by Edi last week. It arrived yesterday and, well, it'd be great, if it didn't look utterly rubbish when it's supposed to be looking its best. That is, when it's set to 1080p 60hz resolution, being fed by an nVidia 6800GT graphics card, over a DVI to HDMI cable.

There's three problems with the image quality. First is that it's blurry. Second is that it's forcibly being oversized, so that the edges of what should be onscreen are lost to the TV's frame, third, is that it appears to be interlaced. There's a youtube video at youtube.com/wat…VyY which might give you an impression of it.

I'm three days from calling Tesco and telling them to send their couriers to take it back. If anyone's got any suggestions on how it can be made to look like it should - that is, crystal clear, pin sharp, and not total pish - I would much appreciate it.

thanks

Buy a graphics card capable of outputting HDMI to your display. It's no good blaming the tv when your system doesn't support it.

But HDMI and DVI are compatible technologies. The only difference between them is that HDMI omits the analogue connectivity and includes lines for audio. And the plug, natch.

What settings have you got set up on your gfx card?

I've given my second PC a shot on it now. It has a 3850 graphics card, the latest Cat 9.4 drivers and Win7, and between the two systems, I've tried running with:

1920*1080 @ 25hz
1920*1080 @ 30hz
1920*1080 @ 50hz
1920*1080 @ 60hz
1780*1000 @ 50hz (which fits the entire display into the frame, but with a border around it, and also blurry quality)

It's been blurry, overscaled, and interlaced at every resolution, with both nV 6800GT and ATI 3850 graphics cards. There's something odd, in that 1360*766 is reported by the TV to the PC as the telly's "native" resolution, and that looks okay, albeit with obvious rescaling, but no blurring or interlacing.

Any thoughts?

The 6800 is over 5 years old is nothing more than a capable low end graphics card. Not good enough for hd tv. I agree there is no need to have hdmi, dvi is all thats required and would probably be the best regardless of the card used. But 6800's are just not good enough.

You could go all 'rock n roll' and chuck it out of a hotel window! :w00t:

some TV will accept 1920x1080 as the input resolution but the screens native resolution is 1366x768 pixel array, in the case of television inputs, many manufacturers will take the input and zoom it out to "overscan" the display by as much as 5% so input resolution is not necessarily display resolution.

where do you get this rubbish from, 'HD' is nothing more than computer digital resolutions which PC users have had for years. 1920x1080 is not a new resolution for PCs.

this is what i was going to say so +1 :P

Op try setting the GFX card to output at 1366x768 you should see a difference.

No it is not new, but using that resolution on a monitor for games or programs is one thing. Trying to watch a high definition movie is something else. HD TV was still in its infancy 5 years ago. The 6800 card was never designed or intended for it. The 7series does a good job but then that was made for the purpose.

The op does not own this card, read the posts.

nm all the gfx, both cards did it so maybe the op was sent/ordered wrong set, from what i remember there were 2 versions of this set posted as deals, 1 full HD and 1 720p, OP check your model number

Most hd TVs dont do 1 to 1 pixel scaling over HDMI which means that any signal over HDMI is seen as a TV signal and resized,I know this sounds ridiculous but this is how they work,The only way to make a PC connection look good on such a TV is to use the VGA input ,Some Sony TVs do PC over HDMI but you need to use the "full pixel" setting ,

Heres a list of TVs that do 1 to 1 pixel mapping,

Okay, tried pushing various buttons on the remote to change scan mode and evrything else I could find, but nothing made it work properly. I've been on the phone to Tesco, and they'll be sending the lorry back for a pickup on Friday. Shame. It's a nice telly otherwise.

Still, on the plus side, that still gives me until thursday evening to box it up. Sucks that all the work and effort that went in to buying it, going to bed early and getting up at 6am so's to not miss the courier, working from 10am until about 2pm on buying and building a unit big enough to fit the thing, and from there having to move the box (which could house an entire family of tramps, and that lead me to suspect that it did when I tried to lift it) up the stairs, but then, I do still have from now until thursday to complete Bioshock on it, impress girl with it, and watch HD porn on it. Yay4that.

Rep for all.
