I recently encountered a small problem when configuring a Samsung LCD TV (UA32EH5000, specifically). Text displayed was fuzzy, looked as if it was anti-aliased with a sort of coloured or sometimes white halo around the text.
The solutions are simple:
- Ensure you set the resolution to native for the screen. For this particular TV, it was 1920 x 1080. You can also try lower resolutions to see if the problem is decreased. 1600 x 900 was quite good in this case, but I wanted to keep the full 1080p resolution so it was a compromise.
- Connect the HDMI cable to the appropriate HDMI port. In my case, HDMI1 was also labelled HDMI1 / DVI so I selected that one. On your remote, press the Source button. Select the appropriate HDMI source.
- You have to rename the source to PC or PC/DVI or equivalent. In this screen’s case, go to Source selection, press the Tools button on your remote, choose “Edit Name” then select “PC”. Doing this disables all processing that the screen does on the image and enables 1:1 pixel mapping. You should instantly see the text become much sharper.
- Adjust the screen settings such as Contrast and Sharpness to change how the text looks like until you like it. I’m using Backlight: 13, Contrast: 85, Brightness: 55, Sharnpess: 65 and other minor adjustments to make the image look good to my eyes. Your settings may vary according to your screen.
Hopefully these should solve your problems. Point #2 did it for me. I didn’t know “Edit Name” could have such a big effect!
Note, you may notice black borders around your image as the image no longer takes the full size of the screen. You need to disable Overscan in your graphics driver. I have an ATI card so for me it was:
- Open ATI Catalyst Control Center.
- From the top, choose Graphics → Desktops and Displays.
- From the display, select Configure.
- Go to the Scaling Options tab and drag the slider to 0%. Your image should now take the full screen.
