Grainy Picture Denon 1740 DVD and Samsung 1080P LA40M81BD

I just bought a denon 1740 dvd player. I have hooked it to my 40" Samsung 1080P and it appears grainier than my last cheap dvd player, i am wondering if I have some settings wrong. Even animated graphics seem to jump a bit. Is there a setting or anything else you thik I should try or is this just a result of something wrong with the hardware,

Firstly, you should alter the picture settings on the TV. Most TVs have independant settings for tuner, scart and HDMI, so you may need to do this several times. Once for each.

Excessive contrast and/or sharpness on an LCD causes graininess, particularly around the edges of moving objects.

Check and adjust the following on the TV:

  • Contrast - about 65% max
  • Sharpness - 20%
These settings are a % of maximum, so you may need to work out a value if max is not 100.

Also turn off any contrast enhancements - (Contrast + / Digital
Contrast etc.) dependant on make.

I assume that you are using the upscaling facility of the Denon 1740 via an HDMI lead. If so, disconnect any other connections between the DVD and TV, particularly scart. If the scart is connected the TV will auto-switch to the scart input when you use the DVD, and you will not get the benefit of the high def connection.

This is probably obvious, but make sure the DVD is set to 1080p scaling, and you will need to manually select the HDMI input on the TV.

I have a Denon AVR 1707 reciever. I am trying to connect my dvd player through RGB cables. The sound works just fine when i turn the reciever to dvd but there is no video. I have the component 2 set to dvd...


The video cables--the green, blue, and red ones must be connected from the video OUT portion of the DVD player to the Component 2 video IN of the Denon. It could be the handshake between your Denon and your television. Do you have anything else to connect to the Denon to see if you get a picture? How are you connecting the Denon to the television? Make sure you have your television on the proper input and check the cables going between it and the Denon.

Go to the Denon Global Website and select Europe, once on the Europe site go to downloads the 1740 will show up in the model drop down menu. You'll need the unit Serial Number, good luck on that, I couldn't find one anywhere on my unit.

Next step? Buy a Sony.

I have a Denon AVR-3808CI A/V receiver, a Samsung HL67A750 DLP TV, a Samsung BD-P1600 Blu-ray player, and a Motorola HDPVR for the cable signal. I have connected the Blu-ray player and HDPVR to the Denon...


You will have to disable one or the other. Most likely the source because not all disk"s will be recorded the same. If a disk was transfered from film to digital poorly, this will show up as a grainy look on your tv, not much you can do about that. I would set your tv the best possible and go with that, also if your tv is capable of 24fps use that setting.tweaktv.com can help you with your tv setting. Use Progressive Mode on you blueray and your dvd also.

No picture


the reason you can't get a signal is the denon 1708 will not pass the 1080p, switch the DVD output res. to 1080i or 720p and it will work

Denon AVR1602


I know the avr 1602 well....What exactly do you mean "I have my TV cable service wired to the Denon".....Do you mean the actual co-ax cable ?....

The denon is only able to switch raw video and audio signals.

What do I mean by that ?....IF you are running your co-ax cable from your cable company directly into the back of the denon, it won't work. The Denon has an AM-FM tuner, but not a video tuner ( channels 1-121)....If this is what you are doing, then you want to run it to your samsung first ( as long as the samsung has a tuner so you can change channels ).

If the samsung operates like an old VCR, whereby you can plug the cable company co-ax cable into the back of it, and change channels with the samsung, then that is what you must do. You would then hook up the OUTPUTS of the samsing to the VCR or DVD inputs on the Denon receiver. ( use DVD inputs on the denon if the samsung has optical audio out, and use an optical cable as well for better sound ).

You would then use the Denon for the sound, and hook up your TV to the Monitor out jack on the back of the Denon.

The Denon is like a big switchbox. You plug your DVD, VCR, Satellite, video game, or what-have-you into the Denon. Then you use the denon to route the signal to your TV for the picture, and the denon takes care of the sound.

Hope this helps, and remember to always follow your owners manual.......Rob
