Windows and Linux implement overscan compensation in different ways. I believe we fixed some bugs since first introduction where overscan was allowed when the HW didn't have the capabilities to implement it without artifacts in all cases; that might be the reason for the behavioural change.

mh9,

That's strange. I'll file a bug and see if we can get a repro so we can debug more directly.

Default No hdmi video on Samsung HL-S6187 with versions newer than 195.36.31

Stephen,

Thanks for taking a look at it.

As Leech and others have said, it doesn't appear to be an issue with the motherboard. Instead, it looks to be something between the driver and my TV (so I guess the thread was actually misnamed). Not quite sure how you are going to reproduce it, though, unless you have one of these TVs.

Again, I am happy to experiment and/or collect data for you.


Leech,

No, 195 does not have the overscan compensation.

mh9,

Do you have another HDMI display device you can test with. That will eliminate whether you're having a problem with your specific TV, or your GPU/chipset. Thanks.

Stephen,

Yes I do, but it is 720p native resolution. Although that shouldn't matter because it doesn't appear to be related to the resolution.

I believe I did this before (can't remember because I tried so many things) but will test again sometime in the next couple days and report back.

Stephen,

Sorry, I did this late the other night and then forgot to post my results.

I hooked the Asus board up to a Samsung 720p LCD in my bedroom, installed the same 260.19.29 version I used in my last tests and it works. However, the resolutions available over hdmi (1920x1080, 1280x720 but not 1360x768) are not the same as those available via the vga port (1360x760) and the colors over hdmi were very washed out. But it did work.

Now what?

Thanks,
mh9

Hi mh9,
Try different HDMI cables and test for two monitors you have with same mother board. Let us know the result.

Sandipt,

Tried three different cables, at least two of which claim to be 1.3. Same results. All cables work fine when used with my dvr and other hdmi devices. Besides, none of the devices require 1.3 so that really shouldn't matter.

Thanks,
mh9

Hello mh9,
As per my understanding ,

1) You are not getting hdmi display on Samsung HL-S6187 DLP TV when startx with drivers newer than 195.36.3 for all three cables with same motherboard AT3N7A-I.
2) For another monitor hdmi display working but you are not getting resolution 1360x768 for all three cables with same motherboard AT3N7A-I.

Now we concentrate on First issue only, that is not getting hdmi display on Samsung HL-S6187 DLP TV but getting on another TV with motherboard AT3N7A-I.

Correct. I can only get 1360x768 when using a vga cable, but I am not worried about this. The only reason we brought this second display into the mix was to verify the issue wasn't chipset related.

Correct. And from all my testing, it appears to me, something in the driver changed immediately after 195.36.31. The next version of the driver (can't recall the number right now, but I did test it) or anything newer thinks it is working and the Xorg logs are effectively identical but the TV gives a "weak or no signal" message.

Another note that might be important. Usually, I can shutdown X, install a driver, start X and the display comes up. However, after installing one of these new drivers, start X, no display, stop X, install 195.36.31 driver, start X...doesn't work. Must completely reboot machine before X will work again.

Thanks,
Mh9

I get the same thing - have you tried custom modelines?
