Help with set-up please!

[Kenetix]

Hi,

I know this topic has probably been discussed a lot of times, but I have to ask you because I found contradictory info on the internet.

I would like to hook up one of my pc's to my LE40B550 but I am not sure about what cables i actually need.

I have an HD4870 1Gb with 2 DVI ports, and i was thinking of buyin a DVI-D to HDMI-M cable, but I read somewhere that DVI cables do not transmit sound (not sure if thats the case nowadays because the post where I read that were old).
So basically, if DVI's do not transmit sound, I would also need a 3.5mm cable that would connect my sound card to the tv's audio hole ? That simple?

Last but not least, I should mention that this PC is not close to the TV, so i would need 30ft long cables at least.

Thanks

With ATI cards there is often an included DVI->HDMI adapter that triggers the cards ability to deliver sound as well via HDMI.

That should solve the problem for you.

Hello Kenetix,
Check if the box has the DVI to HDMI Adapter, we had the same issue some Manufacture do not include the adapter. I know 100% sapphire does.

Also be aware that where you have a PC with a DVI port the PC will likely go into sleep mode if you switch away from it on the TV to view another source - this can make reselecting the PC a bit hit and miss as the PC will not receive the trigger to wake up from the HDMI port on the TV.

If you cant disable the sleep mode on the PC you may have to install an EDID grabber between the PC and the TV - that way the PC thinks its always seeing a monitor:

I am sorry I really dont know what you mean? Well obviously i am not going to spend 129 on that thing, basically because I might as well get an external hard drive with the abitlity to play .mkv files.

So to keep it simple If i dont get that thing I will have a hard time trying to... what? Reconnect my PC display? see anything on the TV?

How can the PC possibly go into sleep mode if I am watching a movie with it? Instead of watching it on my 24 incher I am watching it on my TV, that's the only difference :S

Thanks.

'Without that thing' you may get on fine - then again you are connecting the DVI out of your PC to the HDMI In on your TV when the PC is expecting a DVI Input on a Display that gives it the correct EDID data back when it needs an instruction to come out of Power save mode.

If the HDMI Input on your TV is not designed for use with a PC its quite common to run into EDID issues when connecting a PC - Extended display identification data - Wikipedia, the free encyclopedia

Without the EDID grabber you may find that every time you go back to the PC you have a blank screen and require to reboot the PC.

One question,


If i set up my HDTV as a secondary monitor, will i still have those possible EDID problems??

[Joe Fernand]

Its really a case of try it and see - if it all works as hoped then great; if not the EDID grabber is a good way to sort things out.

My Samsung 32" has the ability to rename the HDMI inputs from a list of possibile options (Games, sat etc) Think your 40 will have the same options. Can't rememember but if you check your manual you may find a specific HDMI is recommended for PC use

If you change the name of the HDMI to PC it actually makes changes to the way that input is handles. Not tried it myself as I use VGA for mine but I know it changes the processing mode and I believe it changes the way the HDMI handles EDID

So, because of such ability, you are not having issues with EDID and your samsumg, and you wouldn't in the event that you used HDMI?

I'll skim through the manual to see if there's any recommendation on which HDMI I should use for PC.

I use VGA so no EDID anyway.
I've not got a PC with HDMI to try, just remember reading about the option in the manual and the thread covering my model TV on here. If you do suffer from the problems above it may help, even if you don't its worth doing as it changes the picture processing options to be more suitable for PC input I beleieve

I found the part in the manual where it suggest what HDMI port I should use. I hope it all runs smoothly when I get the cable :P

Thanks and will get back to you then !

Hello all

VGA>VGA - you'll have EDID; just not the hassles you get over HDMI

PC mode - will likely change the video processing to suit the PC where Black and White have a different electrical value compared with the video world.

Obvious really when a PC can recognise the make of monitor and resolutions available. Doh

PC mode defenitely changes the video processing as thats what I read. Hoping it might even help with any issues with the EDID. Having a HDMI as a dedicated (well switchable anyway) PC HDMI should presumably mean its designed for the job.

I am sorry but Im lost? lol
