Windows 7 showing TV supporting incorrect refresh rate.

by Axodious / July 15, 2011 12:22 AM PDT

I have recently upgraded from a UN40A750 to a UN46D6500VFXZA, the TV is hooked up to a computer running Windows 7. Windows 7 is detecting (I'm guessing through the EDID) that the TV supports 50hz which it does not.

Just a guess

Did you name the input "PC" and try all the other names?

Looks like there is some PC MODE

"Available in PC mode only." and not available if the cable is DVI to HDMI (see the manual?)

Tried all inputs.

I've tried all inputs and I'm using straight HDMI, no DVI. I've also tried and HDMI to DVI cable.

Didn't write about all inputs.

Sorry but I have failed to convey this well.

Call 1800SAMSUNG and have them walk you through the naming of the inputs.

Good luck!

Found what you mean.

I found what you mean however I can't get it to activate PC mode, setting the input to PC doesn't activate any of the extra settings on the TV and I still have the refresh rate problem. I also don't think this will fix the issue even if I can get it to go to PC mode.

I failed on this. While the manual should write how, call 1800SAMSUNG and have them walk you through it.

This isn't an issue with renaming the inputs, there's a firmware issue on the TV, or at least there seems to be.

We have tried ATi and NVidia cards connected to it, both show the exact same issue, so it's not a video driver issue.

Above illustrates the issue, we've tried 2 brand new clean windows installs, the issue appears right away after driver detection.

I did call Samsung yesterday, after 45 minutes of speaking to someone and having them tell me "the TV is too new, there's no new firmware" etc, when that's clearly not true, since owning this new TV, there's been 3 firmware updates. She eventually passed me on to level 2, I went through the issue with him for another 30 minutes, still no resolution to the issue, however he escalated the issue to the engineers.

We have another slightly older Samsung, a unXX750, we never had this issue, Windows always correctly saw the refresh rates, and there was never a display issue.

I was considering plugging back in the older set to the computer, capturing the EDID from it, and forcing it to the newer set, I was however not sure if this would effect 3D/Arc, so I've not ventured down this route yet.

I contacted Microsoft, they said it's an issue, and contact Samsung. The TV should be defining that only a set of valid refresh rates are in fact valid, this set is saying every possible refresh rate is valid, however if you attempt to output @ 25Hz or 50Hz the Unsupported Mode pops.

This wouldn't be an issue, my media players are smart enough to output what the device supports, I have several PAL recorded sets of media, normally with 50/25 being listed as invalid, the player is smart enough to scale the content as needed and output without any degradation. With the TV stating that 25/50 are valid, I have no choice but to lock the display @60Hz, and not allowing the content to play properly, this is causing a ton of judder/skipping/lag, making all of the content unwatchable.

Removing the AMP from the chain makes no difference either, same issue, we have investigated every possible solution and cause, we keep coming back to a TV issue.

Since none of this worked. Add one more thing.

Add the TRANSACTION NUMBERS from your calls to Samsung so the Ambassador has all the details when he gets back on the forums.

If you follow this forum, it's how it gets escalated.

Typo in model number.

Just wanted to point out that the TV is a UN46D6500VFXZC, not a UN46D6500VFXZA.

May not matter.

At this point get the Transaction numbers in your discussion so the Ambassador can kick it up if need be.

Let Samsung do their support.
