HDMI Problem - computer question

Any cable will introduce losses. Funnily enough my son wanted to try and stream some stuff off his laptop to the TV. We used the standard hdmi cable that comes with sky hd+ box and it worked well. The cable is only 2.5m, i would be inclined to use a standard cable to check the screen displays correctly before splashing out on another hdmi cable.
Settings wise, check your pc/laptop is seeing your monitor correctly, via the display settings under control panel. We had to play around to get the sound out of the TV speakers

Sometimes your PC will automatically install a fairly generic display monitor driver, when what you really need to install is the specific driver files that came with your monitor (hopefully on a CD or DVD packaged with it?). Install that driver if you haven't already. If the drivers specific to that monitor weren't provided with it, you can generally download them, if you search online for the monitor's brand and model, then get the driver for your particular operating system.

Would a wireless keyboard/mouse achieve what you want?

How strange that cables introduce losses whereas wifi presumably does not. If I want to use the telly as a monitor I use a vga cable to link it with the laptop then as Pale Rider suggests a wifi keyboard and mouse. No losses although the computer automatically does an adjustment for the resolution so I suppose it has the right driver already. Will have to try HDMI just to see if I get the same problem.

What GPU have you got? this is a scaling problem you get when you output to HDMI from your graphics card.
i got this for a while until i went straight DVI.

i'm guessing you're on an ATI card because Nvidia usually auto scale,
go into your catalyst control centre and choose "my digital flat panels" then scaling options, pick your monitor and set the slider to 0%
this should eliminate the black edges.
let me know how you get on

quick edit. if you're nvidia then open up your nvidia control panel and look under Adjust Desktop Size and Position then Scaling

Why does any scaling need to be done? Surely it is just a case of making sure that the driver is set to the native resolution of the monitor?

 

[Melonfish]

except that it doesn't, look it up it is a very common issue for ATI graphics cards, i had the same issue with my monitor using 1680 x 1050 res when it is native 1920 x 1080, using the scaling options in the catalyst control centre as outlined worked.

Catalist control centre is the standard ATI controller driver that should be installed with your driver package, check your toolbar or control panel for it.
GPU (graphics processing unit) is your graphics card yes.

as for quality loss, i can't comment, make sure you are setting your resolution and aspect ratio to that of your tv, so 1920 X 1080 for full hd or 1280 x 720 for hd ready your resolution slider may not show these until you tell your card which tv you're using, the latest ATI driver (sorry amd now aren't they) should have a wide list of monitors and tv's listed.

sounds like a quality issue of the cable. longer cables need to be much higher quality (£££) to help deal with these issues. Used to see it all the time in the boarding school I worked in. Longer VGA cables for projectors always needed to be much higher quality ones (think we used upto 50m in length at times) and the same applies for HDMI cables - you can get the gold plated one which usually solved the problem.

You should however be fine with a standard 5m VGA cable if you can use one without needing a high quality one.

It's HDMI underscan*. As others have said, there'll be a setting you can adjust in your video settings.

*or overscan: I can never remember which way round it is

 

[Melonfish]

overscan aye

If it were me I would borrow a HDMI lead just to confirm whether or not that displays the screen border. If it does, then you know its probably a Catalyst Centre related issue. If the border isn't present with a different HDMI lead then you know its likely that your 10m cable is a dud.

Simples.

Watched a programme where they said with a digital signal the quality of the cable is unimportant , the device either receives the signal or it does not and if it does then the quality of the picture is the same for a £3 hdmi lead or a £300 hdmi lead.

that is correct.

it doesn't need to be a goldplated oxygen free copper created by sultry maidens in some exotic place.

as long as the connection makes then it will work.

there is a length that a digital signal will stop working but I really cannot be arrised to calculate it at the moment.

Use a projector and make sure nothing is between the projector and the wall where you're pointing it.

Glad I could be of help...
