I did three adjustments that helped quite a bit.
In windows, I used the color management procedure to adjust the hues, brightness, contrast, etc. It didn't help any with the resolution, but it did make the color normal.
Then, in the menu for the UN32EH5300F, I used the picture mode function and selected "movie" instead of dynamic or standard or natural. That made a HUUUUUUGE difference.
Also, I noticed the screen was a bit clipped, so I used "screen fit" on the screen adjustment menu. That matched the picture exactly to the edges of the screen.
Bit by bit, this thing is starting to work. I'm sure it could use some more tweaking.
Thanks for the responses.
I just bought a Samsung UN32EH5300F to use as a computer monitor AND as a smart TV.
-- I have installed it using an HDMI cable from the PC (Windows 7 Home Premium) to the TV in HDMI port 1(DVI).
-- I also have the TV hooked up to the u-verse cable box in HDMI port 2.
It works perfectly for u-verse cable TV.
It is not working very well on the computer.
-- I have the highest resolution selected, and I have done all the MSWindows adjustments I can find (maybe I have not found them all?), but the resolution is still not very good when being used as a monitor.
-- It is usable, but I would think the picture would be at least as good as the four year old 20" computer monitor it replaced. The old monitor is still a lot crisper than the Samsung smart TV.
Are there any more resolution adjustments to make on the PC?
Are there some adjustments to make on the UN32EH5300F itself?
Is there a different driver to use when using a UN32EH5300F as monitor?
Thanks for any help!
