[SOLVED] TV Monitor and HDMI problem

[S_Bard]

I use a tv as a monitor an LG FLATRON M2380A, it has a VGA and an HDMI port. Untill recently i connected the motherboard and the screen via a VGA cable, it looked fine. Now i have a GPU with HDMI and DVI ports, I connected the GPU and screen via HDMI. Turns out tvs are configured in a weird way that you have to change the name of the HDMI to "PC" in the tv options, otherwise it will look "weird". Most smart tvs can do this, mine can't.
So, what can i do? I know there is no damage in the tv, video card, and cables. Its just the weird way tvs are configured. I tried to find "pc drivers" for my display and found some files from LG, but windows insists that it already has the best drivers installed, and couldn´t get it to recognize what i downloaded as an option.
HELP

Examples of the weird input thing:

VGA

HDMI

(these are not from my pc. They are from someone who had the input problem, but solved it changing the name with options from within the tv that i don´t have)

Windows10 home
LG FLATRON M2380A
HD 7870 ghz editon
GA-H61M-DS2 (rev2.2)

What am i looking at exactly with the pictures? Image quality? Edges cut off? The flower in the Hdmi picture looks clearer.

Check TV Hz is set correctly in Windows. 60Hz is it?

It gives off the ilusion of being clearer, but its really not. The edges of the screen are fine, the problem is that everything has a really high contrast, the colours are a bit blinding and everything has a weird glowa round it, changing the colour, contrast, or any configuration on the screen/windows/AMD does nothing to fix this.
It gives off the effect of a better image, but if you look for long enough it just hurts the eyes.
(like how in youtube thumbnails the contrast is super high, at first glance it looks better, but if you pay atention is horrible). This as i mentioned, is caused by some error between HDMI conection to the PC on TVs. Searching for that there might be clearer examples.

So is TV set to 60Hz? Have you tried different pixel formats in Amd software? Ie rgb, YCbCr?

Which Windows and Amd software are you running?

 

[S_Bard]

The tv is set to 60Hz, i have tried others and no change. I have tried all the pixel formats available.
Im using Windows 10 Home and AMD Radeon software with drivers for the 7800 series.

None of these settings change anything related to the problem.

Does sRGB do anything if set for picture preset in TV?

Resolution set to 1080p not 1080i?

I tried and no, i have tried many different resolutions. The problem is the Monitor/TV software/hardware being configured in a weird way for HDMI to PC. The display belives that VGA is the only option for PCs, and if you connect the PC via HDMI it does something weird and ends up looking really bad, and im not being able to configure and fix that directly from the TV options. I need to find a soultion for that.
Anything i change besides that specific problem, will not solve it, just maybe make the problem more tolerable. I could bypass this problem if i get a newer smart tv with more options for configuration, or a standard monitor, but i will leave that for a last resort.
