Custom Resolution Tool for Intel Graphics: Easier Overscan Correction - Page 3

Just another small issue from me..

I added the programs 1080p @ 60, 50 and 24 via. the program to test with.

I am testing my software to detect HD-DVD, Blu-ray, PAL and NTSC material on playback, and change the refresh rate to the correct setting.

However, my projector reports the refresh rates to be 24.03, 50.10 og 60.12 Hz.

What is up with that? 24.03 - my PS3 shows 24p as 23.97.

Is this a thing with the graphics adapter, or is this a thing with the timing values?

(It's a G35 board btw).

Regards,

Brian

Hi Brian,

I suspect timing values. Again, Archibael can probably explain better than me.

If you select the corresponding EIA/CEA "standard timings" (at the bottom of the "calculation" tab) these show the refresh rates you expect (or very close to). Try using these as the starting point and "tune" as required.

Cheers,

Wo0zy

Odd. These actually show up as 50 (dead) 60 (dead) and 23.9825581395349Hz on our systems.

Edit: Shows up within DTD Calculator that is. Is this what DTD Calc shows you as well? The screens I've got don't give me the same level of info as your PJ. Does seem strange. Archi?

Even changing the active pixels doesn't alter this as long as the Pixel Clock, H End of Blanking Interval and V End of Blanking Inteval remain consistant.

Can you post your DTD's for us?

Also, please try the new version with the delimiter fix (you can get this from http://clevertechnologies.co.uk/down...etupdtd100.exe. Archibael may have already updated http://members.cox.net/archibael/setupdtd100.exe as well but I haven't heard yet).

@Wo0zy, FYI m8 the 2600XT works perfectly with the Gigabyte G33.

IMHO the quality of the video and desktop are alot better with the 2600XT than both the G33 or G35.

There were 2 objectives to my new build

1. HD audio over HDMI

2. A nice slimline case

I achieved one of them, I'm a little dissapointed the Intel video didn't work out, guess I will have to wait for the next solution.

My thanks again to both you and archibael for the help I received, I shall be watching this thread with interest.

Thanks for the update m8. Appreciate you taking the time to report back .

Did you use Powrstrip to get a pixel perfect desktop or just the CCC scaling options? Still playing with both options myself. Cheers.

Glad you got 50% of what you want.

The futures bright....

UK chap here also

A new customer UI is due out next year, but it's not clear from the presentations I've read whether it will be for the new chipsets only or whether it will work with G33/G965 etc.

Intel puts out about one new driver for each OS every two months, with some interim bug patches when the OEMs are noisy enough about a problem with the current drivers.

Yes, the DTD calculator shows me 60000, 50000 and 23982,5581...

However when these are actually outputted by the graphics card, the projector shows me the previous mentioned values.

As I see it, there are be two problems:

a) Either the DTD calculator have a minor calculation glitch.
b) Or, the intel graphics card simply gets as near as it can, which is the values mentioned.

There's no need to change my DTD profiles - they are the exact ones from the program.

I'll just try the new version, just a minute.

60 Hz:
02 3A 80 18 71 38 2D 40 58 30 45 00 00 00 00 00 00 1E

50 Hz:

Nah, it's not the DTD Calculator glitching. The 23.98... value is based on the DTD itself, (my pocket calculator gets the same thing) so either the Intel graphics can't get closer than that (which seems odd, but I'll let it go for now) or your projector is misreporting.

Let's assume it's the Intel drivers for now; what if you try to tweak the first value in the DTD up and down a bit? That should alter the pixel clock slightly and you should see a refresh rate impact at your projector. Alternatively, you could try one of the following:

# 1920x1080p @ 23.976Hz (EIA/CEA-861B)
ModeLine "1920x1080" 74.175 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync
# 1920x1080p @ 24Hz (EIA/CEA-861B)
ModeLine "1920x1080" 74.250 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync

Originally I went with timings borrowed from Powerstrip calculations when specifying the DTDs for DTDCalculator, but the other night I dug through the actual EIA-861B spec and found that the Powerstrip timings were slightly innaccurate-- given the particular way in which they were inaccurate, it appears this was done purposely to cope with older graphics cards' requirement that all horizontal values be modulo-8. For instance, Powerstrip 24p is:

Linux modeline parameters:
"1920x1080" 74.250 1920 2560 2608 2752 1080 1084 1089 1125 +hsync +vsync

The differences are slight, but they change the computation enough to make a difference. Give my new values a shot. Wo0zy, I should have sent these to you to include in the new modelines.txt file, sorry I didn't. Friend in from out of town, other stuff on my mind. Heck, might as well post them some people can patch their own modelines.txt file themselves:

That's as near as I can get-- they are directly from the spec. I am concerned with the 1080i stuff since I'm not sure how the drivers will react to an odd number of vertical lines in an interlaced rez (the standard Intel DTDs included with the driver drop to 1124 total lines-- perhaps there's a reason for this), but it's worth a shot.

This is a quite fun to play with ;-) Thank you for the new listings.

The ones that are interesting to me are actually:

1920x1080p @ 59.94Hz, as this equals an NTSC DVD
1920x1080p @ 50Hz, as this equals an PAL DVD
1920x1080p @ 23.976Hz, as this equals most Blu-ray and HD-DVD material from my understaning.

If I do not add any of resolutions, the default of the Intel driver only gives me 25 and 30 Hz options at 1920x1080.

If I had these three, I actually gets both 59 and 60, as well as 23 and 24, and off cause the 50 Hz.

The 23 Hz one does not work, and reverts back to 60.

The 24 Hz works, reports by projector as 24.05 Hz.

Both 59 Hz and 60 Hz works, and reports by projector as 60.12 Hz.

The special thing is is that a 59.94 Hz DTD gives me both 59 and 60 selections, and 23.976Hz gives me both 23 and 24, where 23 does not work.

My guess is that this is the Intel graphics that is unable to output and handle these specifically.

I do not think it's the projector reporting incorrectly, as it reports correctly with the PS3, but that is a wild guess - the PS3 reports as 59.94 Hz and 23.98 Hz so here the projector is able to report correct.

Notice that I am playing with the new G35 chipset on the new Asus HDMI board.

I am not sure if 59.94 vs. 60.12 Hz, and 23.976 vs. 24.05 is a problem.

What does everyone else's display devices report?

Regards,

Brian

Intersting. I'll give it a go but focusing on the other minor issues first.

Great feedback again M8!

Thumbing through my TV manual as we speak to find a button that will give me the information .

If it exists I'll do the same test and report back.

My guess is that this is the Intel graphics that is unable to output and handle these specifically.

Very weird, as some people have reported back judder-free play of Blu-ray, which certainly implies 24Hz is possible. Perhaps at 24.05 it's just not noticable.

Could be a couple of things, actually-- the Intel graphics or the SiI HDMI chip on the board. Video generally runs off a central clock, typically a crystal running at 27Mhz, and the 27MHz clock gets divided down to various pixel clocks which are used to drive the video. Since we're dealing with binary, the clock dividers available are usually very basic numbers and graphics get as close as possible as they can with the dividers they have available. I think either the Intel chipset or the SiI HDMI chip are getting close to 24Hz but can't get there exactly enough to make your monitor see them perfectly.

When you construct a DTD (the 24Hz one from above), try playing with the first hex digit and seeing how your projector reports each attempt. Dropping the first hex digit should have a subtle effect on your pixel clock (should drop it by 10kHz per), which in turn should modify your refresh downward by roughly .005). Again, since it's a binary divider at its heart, you might see an effect like

45h = 24.05
44h = 24.05
43h = 24.05
42h = 23.96
41h = 23.96

etc. Monitors/projectors can be picky about exactly what refresh they will accept, but by spec they're supposed to accept pixel clocks at +/-0.5% of nominal, which is enough to cover the difference between 59.94 and 60.

I'd assume your projector is reporting accurately until proven otherwise.

Yes, the key is not what's reported at your projector, the key is how it looks to you. Both the TV and the graphics drivers have compensation to deal with slight variations of refresh rate... how does it look to you? It's also related to your application: in some cases DVDs will look poor because of a questionable 480i60 --> 1080p24 algorithm in the software, but HD DVD/Blu-ray will look better because the SW assumes they are 24p and doesn't have to convert.

Any suggestions? I can upload a pic of my TV if you don't believe me

Hi,

After some investigation it appears that this happens if you use the tuning tools and the resulting modeline (and therefore DTD) that is generated has an odd number in the "H Start of Sync Pulse" field. To overcome this, change the value to an even number (up one or down one). Also make the same change to "H End of Sync Pulse" so that the Total Sync Pulse Width remains unaltered.

We're trying to figure out why this happens (it shouldn't). All we know is that it isn't a DTD Calc bug but something to do with the way the Intel Drivers are handling custom timings in the last couple of driver releases. If the next driver releases don't fix it then we will look to make a change in DTD Calc to ensure that it will not let users specify an "odd" value. Until then, manually changing as described is the best workaround.

Cheers,

Wo0zy

Thanks! This worked great! Started working on my new Asus G35 based MB tonight and this was just what I needed to override the bad EDID info from my Sony HS20. Didn't realize that you have to right click on the application icon in the start menu to run as administrator. Haven't spent enought time in Vista yet...thanks again!

Hi.....

I am trying this on an Asus P5e-VM HDMI G35 board in windows XP Pro. I can add the custom timings to the registry, but after rebooting the new rez is never listed??

A quick search of the registry shows the correct DTD Count as well as the custom DTD_1 registry value, but the rez is never listed in the video control panel? The only resolutions that are selectable are 640x480 and 720x480??

I am connecting to a Pioneer Elite PRO-530HD RPTV (1080i and 480p scan support) . My goal is to get a desktop rez of 856x480p as well as 1920x1080i support.

Any help appreciated.

Thanks,

Craig

Seems I can add 640x480, and 720x480, but thats all. 1920x1080i and 1280x720p don't show up as selectable resolutions even though the DTD reg key is correctly set.

I think it must be the driver reading the EDID display capabilities incorrectly. It only has 640x480@60Hz, 720x480@60hz, and 1920x540@60hz listed??

Ok got it working

I used powerstrip to write a custom driver for my TV. After I did that all the standard HDTV resolutions showed up and I was able to fine tune them for overscan using the tool.

Great little application, but Intel should really get there act together and write some overscan support into their drivers.

First of all let me say I've probably missed something along the way and a big thanks to all who have taken the time to create this tool. I've spent about 5 total hours trying to get my Intel based Macbook running Vista to display correctly on my 46" 1080i Sammy TV(HL-S4666) using the built in Intel Mobile G965. I'm using DVI to HDMI. I found your tool yesterday and thought this is my answer.

I started with a standard 1280x720 res. After rebooting I ran the ruler tool and was able to size it perfectly for my screen. After reboot the image is the correct size I believe, it is just too far up and to left so I experimented. I used the image in the black box to evenly move both sides to the right and down then saved and rebooted. After reboot it appears to be in the same spot. I load it up again and moved it to the right and down some more and reboot. Once rebooted it still seems to be in the same spot. The third time I attempted to move it, it has reached the bottom and will not let me move it down any more.

PS. What annoys me is that I also have a Dell m1330 laptop running Vista which has the same Intel G965 video and when I connect it using the built in hdmi it displays perfectly, no questions asked.

The DVI and HDMI transmitting chips are likely interacting differently with your monitor, which is why one laptop works and the other does not. Plus there are BIOS differences.

Can you get the EDID from your TV from the Intel Graphics Tray | Information | Save to File ? Post it here and we'll try to figure it out.

I noticed when looking @ the report file. The Dell & Macbook uses different chipsets. Macbook=945 Dell=965
whoops :-(. I still wish I could get it to display correctly.

Here's the EDID

Thanks

OK, I hooked up the Dell and realized it is pushing a res of 1184x666 which looks perfect. Is there a way to just export a driver file or something off the Dell or am I way off?

Same report saved from the Dell when connected to the TV in case it helps.

I have a Toshiba 50HM66, which is a 720p DLP set, and I connect my HTPC via a DVI to HDMI cable. Like most people, I wanted this to fix the overscan issue I had, but after following all of the steps, I'm back to square one.

I found the correct value for my TV, which is 01 1d 00 72 51 d0 1e 20 6e 28 55 00 c4 8e 21 00 00 1e

However, after editing it with the ruler, applying the new value to the registry, and rebooting, selecting the new resolution just gives me a blank (black, with no errors) screen until Windows goes back to the previous working resolution.

Any idea on what I'm doing wrong?

There is a BIOS setting (probably not available to you on the Macbook) which is called "Add Overscan Mode" which adds 1776x1000 when 1080 is detected on EDID, and adds 1184x666 when 720p is detected on EDID. Obviously Dell has availed themselves of this opportunity while Apple has not.

Assuming programmers are lazy-- ahem! "efficient"-- the timings are probably perfectly centered in a normal 720p frame. Using DTDCalculator, put in the following timings (1184x666 centered in the 1280x720 frame):

74.250
1184
1342
1382
1650
666
698
703
750
+hsync +vsync

Check my work, but I get

01 1D A0 D2 41 9A 54 20 9E 8C 05 08 00 00 00 00 00 1E

That should give you the equivalent of what the Dell is doing.

That value is standard 720p@60Hz. What is the new value you're getting and adding to the registry that causes the problem?

I will try this when I get home this afternoon. Thanks again.

Tried that DTD and it showed the same way as when I manually created it. The size looks correct but it is too high and too far to the left(I'm beginning to think somebody doesn't want me to have a HD HTPC). I've got the Dell hooked up now with DTD running, trying to see if there is a way I can just export the exact hex of the DTD that it is running then paste that hex on the Macbook and create the DTD. Sounds simple but I can't find anywhere in DTD calculator to read the DTD that is currently showing, don't even know if that's possible.

grrrrrrrrrrrrrrrrrrr
