Force DVI/HDMI resolutions and refresh rates

How to Force DVI or HDMI Resolutions and Refresh Rates in Windows 7​

   Information
There have been innumerable posts on SevenForums about things like 59Hz refresh rates and 1080p 16:9 HDTVs that display only 1024x768 when connected with DVI or HDMI. After a ton of research and development I think I've got a working solution for virtually all of these issues.



Starting with Vista, Microsoft has required graphics vendors to read and respect monitor capability information from the display itself if they wanted to pass Windows Hardware Quality Labs (WHQL) certification. This display capability data is encapsulated in an EDID. Few HDTV manufacturers sought WHQL and it's unclear whether Microsoft tests display EDIDs from monitor manufacturers as a WHQL requirement. Please let me know if you have a WHQL display that seems to have a bad EDID.

As a result, many DVI/HDMI connected HDTVs and some monitors are locked into displaying only those resolutions and refresh rates that are specified in the EDID. No graphics adapter or driver is supposed to allow configurations not listed in the EDID at least as a default. Newer ATI drivers allow for a small number of HD resolutions to be forced but it's been hit or miss for the users I've surveyed and nVidia's offerings don't seem to be a 100% solution either.

The natural solution would appear to be changing the EDID information in the display. Rarely, this is possible with Powestrip if the display stores the EDID in a flash memory but more commonly the EDID is stored in an EPROM that can only be updated with specialized hardware. I've talked with several display vendors during the development of this tutorial and none of them consider a bad EDID grounds for warranty service. So if next to no displays support updating the EDID through software and the manufacturer won't fix the hardware, what are we left to do? Break out the toolkit and warm up the soldering iron?

While that's well within my capabilities it seems to put some end-users off a bit, although I really can't understand why -- I love the smell of solder in the morning! :geek: But there has to be a better way right? Again, Microsoft has a solution if you really dig for it and do your homework: How to Use an INF to Override the Monitor EDID While it's not intended for end users, what really fun stuff is? The challenge was to develop a method accessible to a greater audience -- to improve on the solution that Microsoft provides that's intended for hardware manufacturers and make it work for us.

Prerequisites
  • Read and understand both linked documents above.
  • Post questions if anything is unclear before you proceed.
  • Don't blame me when you ruin your $3000 HDTV. Smoke can happen.
  • Read up on what your displays true capabilities are stick close to them.
  • This is more of a coffee tutorial than a beer tutorial...






Procedure
  1. Download View attachment Phoenix.zip and extract it to a working folder.
  2. Run it and click the registry toolbar button.
  3. Click the pencil toolbar button for edit mode.
  4. Change the EDID settings to reflect you display's true capabilities
  5. Pay special attention to the Standard Timings tab.
  6. Detailed Timing blocks 2-4 provide some very interested additional options.
  7. Save the EDID to a .DAT file in the working folder.
  8. Download moninfo.exe and install it.
  9. Open the saved .DAT with MonInfo and make sure it doesn't complain about it
  10. If it does post here for help
  11. If MonInfo reads in an displays the settings the way you configured them in Phoenix then...
  12. Select Create INF... from the file menu and save it to the working folder.
  13. Feel free to edit the strings in the INF to your liking.
  14. Open Start, type devmgmt.msc and press Enter.
  15. Select the monitor you want to change, right click and select Update Driver Software
  16. Use the tried and true "Have Disk" method to select the INF and install it.
  17. Reboot and enjoy your new resolution!

I have a crt monitor hp p1230 and it has 140khz horizontal refresh rate max. I just want to get up to 240hz vertical refresh rate at 640x480. Is that possible if I did the pin removal guide? I tried using powerstrip, but that gave me out of sync. If not is there any other way? or is it just impossible?
Please dont ask why i'm doing this, just answer the question plz.

Need help: Force HDMI to show 1900x1200

A little long, but want to make sure I give all relevant info:
Tried again and again to force the HDMI to show a higher resolution using the "INF"-method. But my problem is that when I want to select my "new" improved INF-file it does not load at the "have disk" pop-up window. I can see it there alright. But no dice... Tried many versions of "home grown" INF's to make sure I was not making a mistake but every time I get stuck when trying to select it. :confused:

Here's the problem: I have a high end EIZO bought while I lived in Japan where the DVI connection has died on me (no idea why - and its NOT the video card which I already changed). The model is not sold here in Europe so no EIZO repair possible. The HDMI connection works fine and I can get 1900x1080 in excellent quality. What I cannot have is 1900x1200. I am "sure" this is due to some kind of EDID limitation.

Sadly ATI CCC will let me override EDID on a VGA connection - but not HDMI. :mad:

Clues/suggestions would be very welcome!!!!!

I will continue to post all that I can imagine could be relevant for identifying the problem:

1a) My home made INF file using Barood's excellent guide:

Adapting instructions to Elgato HDMI capture card.

I've been trying to adapt these instructions for my uses, though not with such success as others. I have an Elgato Game Capture HD which I want to use to record the HDMI output of my computer.

The elgato is capable of accepting 1080p at 60 frames per second, this is both by specification and in my practical tests (hooked it up to my Xbox 360 running at that resolution). But either the Elgato's EDID isn't reporting the full capabilities of the device or my Radeon 6870 isn't reading them correctly. There isn't an option for 1080p output when the Elgato is plugged in, so I tried the instructions here.

I got the EDID fine (EGA0001) and added a standard timing block in Phoenix with the attributes; 1920 image width, 16:9 and 60hz. Installed it using Have Disk and restarted. Unfortunately, I encountered a blue screen at every boot and had to roll back to a previous recovery state.

I'm keen to get this working, but I'm not sure where to start tweaking values.

Follow up while writing; I was writing this post on my laptop (Radeon Mobile 4500) and wanted to see if the HDMI port here might show different results, and to my surprise, it did. I can output 1080p to the HDMI at 59hz and it records without issue. I think I can say I'm definitively stumped.

Here's the report from Moninfo;

I'm having trouble getting my Nvidia gtx 650 to output to a 5.1 audio system connected to my monitor. Nvidia says its because the EDID only shows up with stereo enabled. Im assuming if information is stored in the EDID then I can edit it as well. Is that correct?

To follow up in case anyone stumbles on this through Google et al. I found that the issue with my Elgato was that it was broadcasting a different EDID based on whatever output device was connected to. So when I had my Dell ST2210B monitor connected to the output HDMI the Elgato decided that it would broadcast an EDID with a low video bandwidth reading. Not sure why it did that; the monitor was perfectly capable of displaying full HD.

Anyway, when I connected the unit independently or with a newer monitor (I've now got a Viewsonic VX2260wm) it broadcast a more suitable EDID allowing the 1080p60 option to be selected. So on that front all is good. Though I do still find that if the Elgato is plugged in while booting up I still reliably hit a blue screen. More work to be done, but the main goal is accomplished!

Success. 2560x1440 resolution for HDMI/Intel HD4000 on VAIO S13 extern

I have a Dell U2711 I wanted to drive at its native resolution of 2560x1440. Unfortunately the Vaio tools and the Intel driver classify this monitor as a TV and only capable of 1920x1080. I asked Vaio support what was the revision compliance level of the HDMI hardware and they did not understand the question. Small amount of work with the Intel tools, timing specs etc showed that this Vaio(S13 Premium) is HDMI1.4 compliant so should be able to drive 2560x1440, as long as you have a 1.4 compliant HDMI cable. The U2711 supports this as well.

However getting the hardware to do this through the Intel Graphics and Media Control Panel is a bit convoluted and does not always work. The U2711 just did it without adjustment. Some fiddling required. I now have it stable at:-
2560x1440
32bit
54p
CVT-RB

How I did it:-

Modify the Dell monitor driver to show a max resolution for HDMI of 2560 (was 1920). Files attached. Use the manual "I have a disk" method to load these. Note that when you plug the U2711 in it comes up on Device Manager as a second General PnP Monitor. I had to try both to work out which was the U2711 and which was the built in display.
Restart Windows.
Open the Intel Graphics and Media Control Panel in Advanced Mode.
On Multiple Displays page select "Single Display" and in my case "Digital Television Dell U2711"
On the General Settings page ensure Display is showing your external monitor. Probably 1920x1080 32 bit 23p.
Go to the Custom Resolutions page. Click past the warning, mine's been running at this high resolution for a month so I doubt it will fail now.
You need to create a number of custom resolutions so you can then change the settings on the General Settings page one at a time to go from low resolution low scn rate to higher ones. However, the max that the Intel hardware seems happy with is:
2560x1440
32bit
54p
CVT-RB

Now the fiddling begins.

Go to the General Settings page.
Select various of your custom settings until you get 2560x1440 appear in the drop down list under "Resolution", then select that. I then had to decrease the scan rate to 23p, and then to 24p as the driver said the U2711 did not support 23p even though it seemed to at 1920x1080. I also found that if you did not decrease the scan rate the driver said it had applied the new parameters but actually did nothing. When it does apply new parameters the screen blanks for a few seconds. If it comes straight up with the "Accept or change back in 15 seconds" screen then it is fibbing.

With luck you now have 2560x1440 32 bit 24p working.

I also tried starting with 2560x1440 8 bit 23p.

Once you have any 2560x1440 resolution working you can incrementally change each of the Color Depth and Refresh Rate to get to your max parameters.

Note that at 2560x1440 32bit CVT-RB then 54p is stable, 55p blanks out once in a while (presumably it loses synch) but 56p does not work at all.

So the principal is to start with low bandwidth setttings and build up. Sort of sneak around the software. I guess this is just another example where software is less capable than the hardware.

You then just need to ignore all the offers to reset the HDMI resolution and don't go to the Vaio Control Centre and reset the HDMI settings.
BTW works Ok with the nVidia GPU on or off (Speed/Stamina switch) and autorecognises the U2711 when you come home from travelling and puts it into 2560x1440.

ive tried following this tutorial, but ive ran into some trouble.
im using a ~10 year old plasma TV with a dvi output, and i know it can support 1080i on 60hz because it does so for my streamer,
however,
i created a standard timing profile for 1920/1080 with 60hz refresh rate,
and updated the driver as insturcted,
and when i try to change to the new resolution through the screen resolution screen,
i get "out of range" on my tv,
i am not an expert on any of this, and would rather not fiddle with the advanced timings without some guidance,
i wasn't quite able to follow what was said in this thread so any help would be welcome.

Attached are 2 EDIDs i have created:
mar - standard timing profile created, on profile number 6
mar2 - i tried fiddling around with the advanced timing options, but i havent tried actually using it as the driver

Hello everyone. First i want to thank original poster for this miracle cure for win7 refresh rates. It helped me with my crt in the past, but recently i got mitsubishi 21diamondtron crt that can achieve refresh rates of 160 hz in 800x600 and 140hz in 1024x768.I use this monitor as secondary monitor, when i play games. Now my problem is that when i use phoenix tool and try to change resolutions to 140hz i get message that it can set resolutions only between 60hz and 123hz. Here is the picture.



Is there any way to change this to 140 hz? What I also noted is that, sometimes, when i try to load modified inf file,after the system restart it recognize my crt as "Generic Non pnp Monitor". This is the best scenario for me because than i can choose from any resolution and refresh rate I want for my crt. The only problem is that from time to time,after i restart computer (like now for example :/ ) it starts to recognize it as it is and i have no longer luxury of higher refresh rates.
So my questions would be
1.Is there any way to clock monitor refresh rate higher than 123 hz?( that would be better option)
2.Or is there any way to set my secondary monitor(crt) to always be recognized as "Generic Non pnp Monitor"(that would also be fantastic solution)
Best regards.

Stuck on Step 2

Hey guys, I'm a little stuck on Step 2. You see, when I click the registry tool-bar button, the list is empty. I should also mention that I'm running VirtualBox. Would it work if somebody gave me a reference EDID file to edit?

Doesn't work properly

I tried this for my second monitor but it didn't work properly.
When I reboot my pc both monitors run the startup but when I get to the account selection my second monitor turns black. Also the resolution on my first monitor is messed up and I have to manually change it.
(When I open device manager I can now only see one monitor registered.)
Hope you can help me with this,

Emieligeter.

To @Baarod or anyone can help about detailed resolution

I would like to create a detailed resolution based on my monitor's default but in higher refresh rate but i do not know what values to give in Phoenix

I would also like to see if i can create a lower detailed resolution, for example my monitor's native is 1680x1050 at 60hz, but i would like one at 1280x960 or 1280x1024 at 70 or 75hz...

Anyone can help, speak freely :party:

I know it's been a couple of years since this has been made (Almost 10, wow!) But for some reason when I try to extract the edid from the registry I get an error message saying that it's invalid... Would the be due to the program possibly not supporting w10?

Thank you so much

I know the OP will probably never see this. But Ive got to thank you for writing this program. I just went through a nightmare saga of getting my old TV to run with my fresh windows install and my nvidia drivers. I spent close to 20 hours reinstalling windows, drivers, formatting all my drives. All because windows no longer recognized my monitors actual values. Your program and tutorial let me force my way in and make the nvidia drivers read my actual monitor values which were different from the ones windows was feeding it. You literally saved me from throwing my PC off a building.

Thank you so much man who Ill never know.
