Strange Subpixels

Recommended Posts

I'm not sure why I am posting this, but I found it a little odd. I was looking at the temp of my GPU in the system tray on both my 23" 1080p monitor (acer) and my 37" 1080p HDTV (Insignia). The image was mirrored so there was no difference in output other than HDMI (to TV) vs HDMI (to monitor).

 

The TV made the temperature number look awful, but the monitor made it look quite sharp. I decided to take super-macro pictures of each to figure out what was going on. I still have no idea what is happening, but the TV has some really strange sub-pixel arrangement, almost like chevrons. I've never seen that before. The red number 4 in the picture should only be two pixels wide, but on the TV it seems to be blurred and bleeding out to surrounding pixels.

 

Is there anything I can do to correct the bleeding? I know the pixel arrangement cannot be helped though :/

Is the TV doing any edge enhancement? I'm noticing all of the edges in that image being distorted compared to the monitor, and I know TVs have an edge enhancement capability I don't think many monitors have. Basically TVs have the ability to process images in ways most monitors don't, and this processing is not always good.

If you go in and turn down the edge enhancement though you may actually make the problem worse :lol: Every TV I've seen an edge enhancement option on can either make the edge sharper or blurrier, with the no-enhancement setting in the middle.

At least, that is my first guess at what may be going on.

I have a similar issue with my 40“ only half fix for me is running VGA rather than hdmi

That's definitely due to some sort of filter. Sharpness would be my first guess too.

Unfortunately there is no way that I know of to turn "edge enhancement" off if it is indeed on by default. I messed with the brightness and sharpness settings but found no difference in clarity.

 

I would try to run VGA to see if it makes a difference, but I don't have an DVI-->VGA adapter at my college apartment :(

 

I'm no genius when it comes to how TVs/monitors work, so I didn't even think of the filter issue :lol:
