Well, the first thought is you may need to have the set calibrated. Most sets are shipped completely out of adjustment, so if you want it to look as best as the set can, then you probably should have it professionally calibrated. Second, you need the right program material - 4K content. You can get that from several input sources, including 4K discs. Just remember you will need a player that can handle 4K, cables that have 4K bandwidth capability, and if you use one, an AV receiver that processes 4K signals.

Next thought is you may need to rethink how your viewing room is set up. Generally, glare and bright lights can make the video image look more washed out than a darker room. There are a number of good articles on how to set up a room for really good viewing.

Final thought about how the set should look - it may take 60 to 80 hours of viewing time for everything to settle down in your set's electronics. Some things really do get better with age! After that, then consider having the set calibrated.

Good luck, and happy viewing...

sure, but why? The one in the machine will handle just about anything short of VR.

yes. that's what I used to install mine.

It's most likely due to the resolution you selected on the scan dialogue. For example, if you're scanning those 4 pages at 600 dpi in full color into a searchable PDF, that adds up. If there are images involved in addition to b/w text, then file size grows even more. Try setting the scan resolution to 200 dpi.
