Thanks for reply.The PC should be just another input, I have just plugged into a few TVs over the years.
Oh I did, neither produced an acceptable image. Both images looked washed out like my LG until it is put in PC Mode but the Hitachi doesn't have the PC Mode option. I tried every setting on the Hitachi but nothing made the image better.Try one of the HDMI connections.
Worth a go.
Thanks Next010. Yes I tried every setting there is on my NVidia, I read before about changing the settings, it didn't do a thing to help the image on the (now returned to shop) Hitachi.Does your GPU have a YUV output mode in its settings Intel, AMD and Nvidia usually do, some TV's process YUV a little better.
It's buried away in the Intel GPU control panel, in the AMD/nvidia go to their resolutions section and override the default RGB output then select 8-bit YUV/YCC 444.
Your LG & Hitachi TV's HDMI black level should be on low/limited 16-235 to match the YUV, don't use PC/game mode set the TV to movie mode or something like that.
Also dont use any 0-255 to 16-235 converters in media playback software (e.g. Kodi) as the GPU is alreading doing the YUV conversion at the system wide level and the OS/software is unaware.

I do use KODI and the settings don't seem to make any difference, only changes in Windows 10 Display Settings seem to make a difference.
I have gone back to my broken LG (bottom of screen is dying) and I think I will look for a new LG to replace the broken one.
I mentioned on another thread that everything seems to come down to the selection of PC in the LG Input Settings( see image below), without PC selected the image is washed out and jagged.
The PC mode is a RGB, chroma 444, 0-255 which is what PC's output by default.
TV's picture presets typically have a default of YUV or RGB, chroma 422, 16-235 for AV devices.
If your PC is set to RGB Limited or YUV output in NV control panel it should not be washed out if TV is on 16-236 (low/limited) and using a cinema/movie picture preset.
You also must remove the PC mode label on the HDMI to disable the PC mode as it will override whatever AV picture mode like cinema that you select.
As for the jagged look that is perhaps the lack of chroma 444 which will make PC desktop text harder to read, if your only using it for movie playback then it isnt usually a problem but if you are then you should seek a display that has a PC mode with chroma 444 support, look at rtings reviews they mention it under the supported resolution section.
Black level was set to AUTO, I switched it to LOW and it went really dark but no change in image quality that I could see.
I set the YCC 422 and the image looked worse, text looked like a VGA low res input, I then turned off PC mode and it looked even worse. I learned from tweaking the NVidia Control Panel while trying to sort out the Hitach that it is best left to Default Colour Settings.
Thanks again for all your help and patience, really. I will start a new thread here on the forums simply asking LG owners if they have the same menu setup as I have on my (bought in) 2016 model and if they say they do then I shall assume that my PC will display correctly on that TV.
Those auto modes can be unreliable.
The text degradation is definitely chroma 444 related so anything other than PC mode sending RGB/YCC 444 will not render text correctly. On your LG model its very noticeable but for other models it may not.
