Connecting PC to TV for desktop use

[deamer44]

Hey all im new to this forum, just thought i could get a little help with my situation.

I want to hook up my graphics card (3850) to my tv ( Acoustic Solutions 26") -http://www.argos.co.uk/static/...ACOUSTIC+SOLUTIONS.htm

As you can see it doesn't have a PC input. So i was wondering would it be better to go DVI-> HDMI or sd to component. Ive used DVI-> HDMI before and the letters seem a little bit blury, so which one do you think i should use


Many thanks Tom

Either one will make your letters look a bit blurry (you'll have to play with some resolution settings). My intuition tells me that DVI -> HDMI would be the best, but I don't see how it would be much different then going straight through composite.

WTF?

Composite and DVI are on opposite ends of the spectrum. With composite you get 576 lines of composite video. That means ass-loads of dot crawl, no more than 480i, and overall terrible quality.

Single Link DVI can do 1080p24, in full YUV components!!

If you're getting blurry text, that means that (crappy) scaling is happening somewhere. You need to know the following

1) What is your LCD's native resolution
2) Does it display this resolution with or without overscanning
3) Can you configure your PC to output this native resolution?
4) Can you live with the overscan, if present, and if not, can you compensate for it?

You want to feed the TV its native resolution, or let it do 1:1 pixel mapping. It's tricky - every TV is different.

AVSForum.com is a good place to research your particular TV.

If you have a 720p or 1080p TV, you should not have any issues with blurry text

well my tv goes up to 1080i, which i think is 720p streched?
how do i find out the native resolution?
Ill have a look on that website thanks m8

 

[deamer44]

1366 x 768 pixels. thats what it says the resolution is at so im assuming thats the native?

 

[themisfit610]

Yes. Your TV is 720p, but it can accept a 1080i signal. It will most likely be easiest to send it 720p (which is technically 1280x720). In your case, that means 1366x768. Try setting your PC to output that over DVI -> HDMI. There may be overscan (areas of the desktop clipped out), so you might have to compensate for that. The ATi driver should have something about it.

Thanks, is there any program that can change the resolution to 1366x768. As it is not an option.

I believe you can do 1360x768 which is close enough. As long as your TV supports 1:1 pixel mapping you should be good to go. If it doesn't then it will look horrible (for text anyways).

 

[themisfit610]

You should be able to generate custom resolutions somehow, if nothing else by using powerstrip

 

[deamer44]

how can i find out if it has 1:1 pixel mapping??

 

[themisfit610]

Not sure, you might want to do some research on avsforum.com.

Alternatively, set your display resolution to "true" 720p - i.e. 1280x720, and see what happens If you get a clean image with black borders on all sides, you know the TV is doing 1:1. Poke around the menus too, if you can.
