What brand and make is your TV damoh?

Welcome to HUMAX [Global Website]

That one mate,

Re: Previous post, i have adjusted the RGB, the image is only slightly better but no where as good as the monitor. The white colours are very dull, beige in colour.
This is where it gets a little tricky. My monitor supports HDMI so i messed around with that a little, this is what i ended up doing:

My monitor ( hanspree 19inch ) i connected using HDMI. no on this i get the same purple colour as the TV and i cant seem to make it any better.
If i connect my TV using VGA then the image is perfect. I managed to get the TV to display the HDMI only once and since then i cannot get it to display again.

So a small round up of the facts;

- On either the monitor and the TV using the HDMI cable causes colour distortion
- Using the VGA cable though produces normal colour on both. Yet you don't really want to be using VGA when you can be using HDMI.

Now, as HDMI outputs through digital I'm doubting its the cable itself.
So it could possibly be your graphics card that is doing it with the current drivers.

You have a few options I'm guessing to deduce the problem;
- You could try rolling back to the previous drivers? In Cod4 for example the new Nvidia drivers caused graphics distortion on my card and the old drivers work better.
- If you have a friend with a laptop, a hdmi port and vista you could try that to see if the tv works perfectly. If so then it's just Windows 7, which means back to the drawing board. haha.

Yeah my mate has a computer with HDMI, ill pop the TV round tommorow and try it. Its not a massive TV so transporting it easy

Sounds like the color temperature or white point setting. This is related to but separate from the RGB ramp. See if your TV menus allow you to adjust color temp -- the setting will either be general, like "cool, warm, normal" or Kelvin degrees like 9300 or even phosphor technology used like "B22, EBU, or P22". Also look for the gamma setting and try adjusting that. What would really help me here is for you to dump your TV EDID using http://www.entechtaiwan.com/files/moninfo.exe. It's free and not evil

My monitor ( hanspree 19inch ) i connected using HDMI. no on this i get the same purple colour as the TV and i cant seem to make it any better.

Try moninfo on that too and lets see what it says.

If i connect my TV using VGA then the image is perfect.

Is that using a VGA plug on the back of the TV and a VGA cable attached to a VGA port on your video card or a DVI or HDMI to VGA adapter? That makes a difference as the monitor EDID will not be available that way.

I managed to get the TV to display the HDMI only once and since then i cannot get it to display again.

Just a black screen right? Can you hook the Hanspree monitor AND the HUMAX TV up to the computer at the same time? Like one on VGA and the other on HDMI? Doing that you can adjust the HDMI settings for the TV while looking at the monitor. That makes this much easier.

I'm suspecting the TV's EDID -- I'm combing the docs on the website now... So much for that -- docs are in German. Got a link for English?

HDMI works fine for me

I'm using my notebook - HP 8710p (NVidia Quadro NVS320M) with a Mitsubishi HC4700 FullHD beamer at home. Connection via HDMI works like a charm.

As soon as it's plugged in, I get an extended desktop. Even the really bad ideas like putting the system to standby while connected to the beamer and then waking it up connected to the office docking-station with a secondard (DVI-connected) display works perfect. I get 5 seconds of auto-desktop-rearranging with some flashing of the screens - then I'm ready to go.

So - in general: HDMI seems to work just fine - as long a the devices handshake correctly and are fully compliant.

Hi

To clarify Baarod. My TV has a VGA input on it. When i connect that to the computer the image on the TV is perfect.
HDMI on the TV still no go
The HDMI on the monitor is a purple colour usable to a degree but really wierd to look at. The whites are beige and so forth.
I did what you recomended with the dump, i saved the info as a text file and attached it to this post.

Many Thanks for your help so far
Regards

 

[damoh]

i have a DVI port on my computer, so if anyone thinks that using an adapter plugged from my GC to the HDMI cable would work then ill go out and buy one

Those are absolutely perfect EDIDs -- your TV even has the extension data. I'm about 80% sure this is a damaged HDMI cable at this point. The other possibility is that there's some damage to the hardware or electronics of the HDMI plug on your computer. It is a HDMI plug right? Not a DVI-HDMI adapter?

There's a remote possibility that you have a really bad ICM profile but I've never seen one override the EDID data.

Can you borrow another HDMI cable and try that?

Also, hook the TV up via HDMI and the monitor up via VGA and check if the screen resolution control panel shows both -- you know, right click the desktop and select Screen Resolution. You might have to hit the Detect button or change the Multiple displays setting to Extend...

What video card are you using? Some drivers have an option to use an alternate digital timing that will fix those speckles. How about some rep for me?

 

[damoh]

im using a nvidia gforce 9500gt

and rep is most definatly coming your way

Thanks!

Have you tried changing resolution to fix the speckles? Just use the screen resolution control panel in 7 to try different refresh rates. You'll need to click the Advanced settings link and choose the Monitor tab. Try 60 vs 50 Hz if that's available.

 

[tweakw7]

Btw, if you havn't bought the cable yet don't blow a crapload on an expensive HDMI cable, the cheap ones are all the same.

hi 50 mhz is there but no 60 mhz, neither one improves, quite the opposite infact, the screen goes all purple again and it wont come normal again until i reboot the computer

I few things he said are making me think he's got another monitor -- one in addition to the HDMI-connected TV -- connected at the same time. Perhaps he just needs to extend the desktop?

I see this is an old post but maybe I can still get some answers for my setup.
My Graphics card has a DVI out put which I have connected to the HDMI input on the LCD TV. The only picture I can get is the background picture of the computer (It is in HDensity and looks great but cannot get anything else. When I switch to HDMI on the TV the monitor goes out for a few seconds and then starts up again.
My card is an ATI Radeon HD 2400 Pro.
Thought it would be easy as well but sadly not so.
Any help? by the way this is in W7. I have dual boot system and in XP I do get a picture on the TV which is "Terrible" and the Monitor switches itself off, so that's no good.
