I really don't know the answer, but here's some deduction and guesswork.
You're getting colour on bootup, so there's a good connection. My first guess is that neither HDMI cable is up to it. Try going into the display settings. Look to see if you can find any setting that might say PAL or NTSC - it may be that a UK set can't do NTSC (American colour system). Next, try reducing the desktop resolution on the laptop. For a full HD TV, it should be 1920x1080. It should be at this. If it's above, it's being wasted and you should reduce it to that. If it's at that, reduce it further to see if the colour comes back. If it does, I'll blame (both) the HDMI cable(s). They can't handle the badwidth being thrown down them by the computer. Would be worth testing other ones, and maybe even buying a higher quality one (Like, £10 on Amazon, not £20 in PC World!).

have you tried via vga on tv? (assuming it has one of course
also may i ask what is the exact model number of tv? also have you tried fiddling with tv options?

Since you're getting colour during boot is NOT the cable, the cable sounds fine.
It's either a Driver issue with the Graphics card (since windows basic drivers are used during boot and the main drivers kick-in after boot.)
or the Monitor / TV. what's your PC and TV make and model and we might be able to help you more...

Hi Guys

Thank you so much for your replies, it is a Samsung LE40R88BDX/FEU.
The graphics card is an Nvidia 9600gt i think??
The PC is a Medion one from Lidl or Aldi.
I think my mate came round and tried vga to hdmi, using an adaptor and it was still b&w.
It's only b&w on one certain resolution (the one that fits the screen best)
Sorry I can't give more detail but I'm not at home just now and not very good with techy stuff lol.

There are no new graphics updates/drivers from Nvidea, i apparently have the latest ones already.

Not sure what TV settings I should have.
The TV has 3 HDMI plugs in it and tried the HDMI in each plug, each one produced a different range of settings on the pc
(for example- plug one will show a resolution as very zoomed in, while plug 2 on the same resolution will be very zoomed out)

This only recently occurred, it worked fine for 2 years with pc previous to this. No known changes which would cause this , no new updates or downloads or anything, just put it on one day and it was black and white.

if you have latest drivers you should have nvidia control centre on you pc.
right click on the desktop and select Nvidia control panel
click on adjust desktop colour settings, there might be some tv specific option there that can resolve issue, 'if digital vibrance is set to zero % move it up a bit

After 3 hours of Google-ing last night, I've came across the hue and digital vibrance sliders issue a lot, but all my sliders are set at the right bits and even trying to change them just make the tiny dull bit of colour poking through the b&w go just a little brighter or a little more shaded.
It's very odd.

hmm damnit and so when you select display options on tv remotes there is no mention of any kind of display option that might affect it?

I haven't tried the settings on teh actual TV yet, I just assumed the problem was something to do with the PC/graphics card

Giant_Space_Lizard

so just to clarify it only goes b&w at the native resolution 1366x768?? but at all other res works absolutely fine?

do you use windows vita/7? i very much doubt the 9600 cannot handle it (i am certain actually it is decent card) but try anyways disabling windows aero on the desktop, cant hurt to double check


ah well if definately worth fiddling with the tv options there could be a clear = 'pc mode' etc.... that for whatever reason wasnt required when you use your previous pc

It has windows vista on it :-)
It's the same PC I'm using, nothing changed, just one day it showed up black and white.
Will try the TV settings when I'm back home. Cheers :-)
