Situation

Its not cabling thats the issue. The TV shows visual but the graphics is very hazy and blurry. I suppose it has something to do with either the frame rate made for digital monitors being too high for the TV or the video resolution being too unbarable.

I have used CRT computer monitors but they used VGA. In those monitors, I used to set resolution to 800x600px and it would show the clearest. CRT monitors dont have this concept of pixels, yet setting pixels to 800x600 does the job in VGA CRT monitors. It did not work in case of my TV.

I should mention that the device I purchased to convert HDMI to Audio Video has a toggleable switch that can be changed to NTSC or PAL. I dont know what that is, both works but setting to PAL seems to be slightly clearer.

I am asking here in hopes someone else has done it and how they made it barable.

[Also I am sorry I do not understand the language that is mostly used here. This community seems to be the most active one so I decided to ask for help here]

    I think we’re gonna need a picture.

    Sounds like you may not be particularly familiar with CRT TVs, which had much lower fidelity than VGA monitors of the era.

    640x480 resolution is more along the lines of a target resolution you’d be aiming for. And even that is pushing the limits. You aren’t going to be seeing individual pixels unless you go down to 320x240, and even that’s with some squinting and imagination.

    What you’re describing may be completely normal for a CRT TV. Particularly one using composite cables (yellow/red/white) at any point in the chain.
