Hey all. I just put together a new pc using my old monitor, old pc is gone.

Using a MSI 7850. The problem is that via HDMI the colors look all washed out and wrong. A few hours of googling and poking through the OCF search didn't really find any solutions so here goes.

What do I do to fix it? I had the problem before on my old computer (Nvidia card) but and it went away when I used a DVI-HDMI converter dealio so I just left that in place, but that's in a cargo crate in the pacific somewhere right now and not accessible.

If I move my box to the living room and use the other TV it looks fine when I change the input name to DVI-PC but that's not possible with this one.

I've used a different HDMI cable and checked TV presets (warm/cold/etc, game/standard/movie modes, RGB/cymwhatever 444/422 options, etc.) and am at a loss. Tried changing monitor and control panel brightness/gama/color levels to no avail (reset them back to default afterwards)

Samgsung UN22D5000NFXZA display. Just your regular 22ish inch 1080p display.

Mobo: MSI 970A-G46 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX
CPU: AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Quad-core.
RAM: CORSAIR 4GB (2 x 2GB) DDR3 1333 - $21.99
Case: Rosewill R-5
PSU: Rosewill 550w
HDD: Western Digital Caviar Blue WD5000AAKX 500GB 6.0Gb/s
GPU: MSI R7850 Twin Frozr 2GD5/OC Radeon HD 7850 2GB

Just trying to see if there's a software fix, since it seems video card makers haven't fixed this problem over the last couple of years heh.

Thanks!

I get this on my TV, when i try to play at too high a resolution, try reducing the res down a notch or 3.

Tried going to catalyst control panel and try adjusting pixel timing and such there? I assume by TV preset you are changing setting on the monitor itself?

I have a Samsung Monitor myself. On mine there is a setting in the onboard menu that may help. It is under Menu>Setup & Rest>PC/AV make sure you have it set to PC.

You may want to calibrate your monitior.

The problem is HDMI. Most graphic cards assume a limited Range HDMI connection, therefore limiting the colour range. You can correct this by either looking deep into your driver (Catalyst Control Center) and search for something like "full range RGB" instead of "limited range RGB", or try to change this on your monitor.

This drove me nuts for about 2 days, but this will surely solve your problem.

Yeah, it normals out when I'm at weird resolutions... 1080/720p doesn't work properly, but if I lower it to weird ones

Video mode is set to RGB 4:4:4 Full, was trying RGB/CYMwhatever 4:2:2 and 4:4:4 earlier with 1080, no dice.

Sadly with this monitor I can't set pc/av/etc modes, or rename the input. On my other TV I can, simply naming the HDMI port "PC" instantly fixed the problem (which is that it's cropping off the edges thinking that they're black bars or something then upscaling to fit the screen)

This annoys the **** out of me, before when running a 90's analog VGA cable it looks just fine. Try to use current technology? Nope. Sadly the stores near me have VGA cables, but no DVI-VGA adapters, and my video card didn't have one either.

i have duel monitors (identical) ones on hdmi other uses dvi... the dvi looks heaps better, like you, the hdmi one looks a little washed out, lacking the "pop" the opther one has. Soon as i can be assed and stop being lazy i shall be replacing the hdmi with a dvi, dont use the sound form the monitors so not like i will be losing anything.

Hey Tabrin,

Did you fix your colour problem already? I tried to google your monitor and it seems like it is an LCD TV actually.

Your problem is: most home appliances like DVD-players etc. Only support limited range of colours in RGB. If your monitor awaits full range, he is not able to display a true black or white screen is the limited range stops at a dark grey. Thtat is why he has to compute the signal and match it to a full scale colour code. It is a little complicated to describe as I am not a native speaker :-)

In your case, it seems that everytime you use a "home appliance" resolution, he assumes a limited range signal while instantly switching to full range if you use a slightly different resolution as only PCs capable of sending full range can produce this.

There should be two or three ways to solve it:

1. Try to set your graphics card to limited range on RGB or your monitor to full range.

2. Use another connection. i think it could work with a DVI2HDMI-adaptor with a DVI cable instead of using a single HDMI cable. Maybe your monitor recognizes that you are not using a home appliance and grants you full range.

3. Last possibility, set up a custom resolution in thegraphics card driver like 1919x1079. You won't notice the two lines missing but this should convince your monitor to get a full range signal.

Hope this helps...

YOUR TV HAS DIFFERENT COLOR/IMAGE PROFILES FOR DIFFRENT INPUTS.


That means if you are having beautiful colors, with VGA cable, you can still have power-saving-ultra-color-fade profile active if you plug in your HDMI.
