Trouble with Dual monitor output ATI Radeon (monitor and HDTV)

Q: Trouble with Dual monitor output ATI Radeon (monitor and HDTV)

I have an ATI Radeon 4670 card. I have not had trouble getting it to "Dual Display" in the past. Usually I wanted to do an extended display. I am now trying to get it set up with my HDTV with HDMI. I have added the Realtech drivers and HDMI adapter to the video card and have been able to get HDMI and digital sound to the HDTV, I am trying to get the two displayed as clones.

The problem I am having is after getting Catalyst to display the HDTV, I have lost the image on the monitor. In the process of trying to get it back to both displays I have accidently made the HDTV an extension of the monitor. Which is really a cluster as I can not get to the control panel to make any changes. All I have is the extension showing on the big TV but none of the controls. I tried rebooting in safe mode but was unable to access the catalyst control center as it did not boot in safe mode. The big plus is that in safe mode both screens are visible, but I can not undo the Catalyst settings. I am now running a system restore which will take me back to tomorrow settings, which is not ideal but better than not being able to access anything outside of safe mode.

How do I get the TV and monitor to display at the same time?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

I'm using a Radeon HD 3450 on Windows 7 with Catalyst 10.7

My monitor is connected through the VGA port, and it works fine.

I tried to connect my HDTV (LG 50PK350) as a second monitor through the HDMI port (on TV & HD3450). The TV (as 2nd monitor) is not detected and there is no signal on my TV.

The connection appears fine, as when I click 'Detect Displays' in CCC, the pc monitor screen flickers and tries to connect but eventually fails. (same using Windows 7 Display properties!).

I am using a brand new HDMI 1.4 cable.

Any ideas?


A:Dual Monitor (HDTV) Problem Radeon HD3450

Card have VGA, DVI and HDMI ports? If so the reason it won't work with the HDMI and VGA at the same time is both of those ports are running through the same RAMDAC, and only one of them can be used at a time.

If you can hook your monitor up to the DVI port using either a DVI cable, or if the monitor doesn't have a DVI port on it the card should have come with a DVI-VGA adapter. If it didn't you should be able to find one fairly cheaply, like this one,

Hello I basically need conformation that I'll need to buy a new monitor in order to have a dual monitor set up with my current system. I'm not super tech savvy so if you need any other info please let me know.

I have a Radeon HD 6670 with 3 ports, an HMID, VGA (which is my monitors type) and DVI. Each port has a stamp next to it that indicates what port type it is/supports (the VGA has a CRI stamp next to it though). My main VGA monitor works fine with the VGA/CRI port, but my second I have to use a VGA to DVI adapter and it's not working.

I've gone through a lot of forums, and found some conflicting information. So I really want to know is it possible to use a converter/adapter or will I need to just go out and buy a new monitor that has a DVI hook up?

I hope I don't need a new monitor, I'm on a very tight budget. (la sigh)

A:Radeon HD 6670 Dual Monitor setup not detecting 2nd monitor

I would try one of these before giving up on the monitor:

Rosewill 10ft. DVI-A (24+5) Male to HD15 VGA Male Analog Video Cable w/ Ferrites Cores, Model RCW-900 - Newegg.com

Forget adapters, you might not a have a compatible one, the DVI connector has many variants.

Look at that cable end and make sure it would fit on your video card's female DVI connector (it should), it's DVI-A (analog only) to VGA which is analog only....

I am having troubles getting my dual monitors back.
Initially had a GeForce 8400GS 512MB PCI video card and was using the on board video (Biostar G41 M7 MB) for dual VGA monitor setup.

I've installed a Radeon HD 6670 1GB PCI-E video card with monitor one setup via DVI to VGA adapter on output one and 2nd monitor on VGA onboard video.
I cannot get the second monitor to detect in any configuration. Tried looking in BIOS of MB, using 2nd DVI (w/ vga adapter) on Radeon card.

Am at a loss and I hope I have provided enough information for some assistance.

I don't understand why you are using a combination of DVI (to VGA) out of your HD6670 to one monitor, and also using the VGA out of your motherboard to the other monitor.

Am I interpreting what you've done correctly? You are using just the DVI output from your HD6670 through a DVI-to-VGA adapter and on to your first monitor, and also using the VGA output from the onboard graphics of the motherboard to feed the second monitor? If so, this is very wrong.

Your new HD6670 has TWO video outputs of its own: one is DVI, and the other is VGA. You should connect your second analog monitor to the VGA output of the HD6670, not to the onboard graphics VGA output.

Also, if you can disable the onboard graphics in the BIOS that's definitely what you should do when you install an external video card as you've done. At the very least you should give priority to the new PCIe video over PCI (which was your old GeForce card, and probably o... Read more

Hey Ho Everybody!

I am running a self-built computer with the following specs:
AMD Athlon 64 X2 6000+ Dual Core
Gigabyte GA-M52L-S3 Motherboard
Foxconn Nvidia Geforce 9500GT 512MB Graphics card

I was thinking of buying two 19” TFT-monitors and using them as dual monitors. Preferably, I would like to use DVI to connect them. My graphics card, however, does not have dual DVI outputs. Would it be possible to buy another graphics card, such as the “MSI HD 2600 PRO PCI-E”, which has dual DVI, and using these cards simultaneously?

Secondly, I was wondering if it would be possible to connect the computer to a HDTV as well for streaming video and playing games etc. In that case, could I connect it to my primary graphics card, Nvidia Geforce 9500GT 512MB, while using the secondary graphics card for the monitors? Would the HDTV then have a cloned picture of both the monitors or just one of them? Is this even possible?

Thankful for answers

I recently bought an HDTV with a VGA port in the back. The first time I plugged my laptop into the TV via VGA it worked fine and the images popped up on the TV. A menu popped up asking me how to display the monitors and I set it to display only on the HDTV and not the laptop screen. I then tried to run a game through the HDTV screen and it didn't work and now when I plug the laptop into the TV I just get a black screen with a message saying something about the mode not accessible. Is there anyway to bring back that initial pop up window so that I can set the screen to display on both the laptop and the HDTV?

Thank you.

I apologize if this question has been answered before, but I couldn't find it.

I'm running dual monitors on a laptop, the set up works fine with one minor exception. When I try to view videos in quicktime or windows media player it outputs in full screen to the monitor that the player is not on. This also happens with videos in browsers. http://members.aol.com/jrzycrim01/mozilla/wmp/vidtest-HS.html is an example of this happening. I can only assume it has to do with my video codec, I am using the windows defaults and cyberlink powerDVD as my mpeg2 decoder.

Radeon 9000, i have a primary monitor in the monitor spot, and a VGA cable attached to the card as well.

If i go into display, i can activate the second monitor (VGA) , and it will work just fine.

I want the VGA to boot up as the primary monitor.

I have tried
Disconnecting the regular monitor during boot
Changing around a little bit of bio's (compaq bios suck)
Updating drivers.

Is there anyone to just swap the display settings (making the vga port primary) and forcing it to save as the default???

I have HP Desktop Tower Pavilion with windows 10, I had two HP S2031 monitors in dual mode, worked fine. One of them died, I got a good deal on a larger HP 27er monitor.  I hooked it up, they were both working fine ... it was using a default monitor
setting ... and then yesterday the computer downloaded some updates, and in doing so, it downloaded the driver for the HP 27er and installed.  The next thing that happens is the older HP S2031 starts to go dark ... like it is going into sleep mode, and
then it is totally black.  On reboot, it starts up with both monitors working, but within seconds of reboot the HP S2031 goes black again. The HP S2031's buttons do nothing, other than the power button, which turns it off and on, but that is it.  
I have done all troubleshooting, I did not even have them set up to sleep, all settings are at NEVER.  In coming here, I have done all the fixes I can find for similar  that are posted for similar issues, the Windows Key + W... nothing. 
The create new power plan ... nothing.  the device manger>display adapters>disable then enable ... nothing.  and lastly Start>Control Panel>System>Device Manager>display adapter>driver tap>update ... still nothing.  HOW

Alright, so I recently got a VGA cable so I can hook up my PC Laptop to my tv. It worked fine at first, but I needed to optimize the resolution to my TV. I set it to only show the screen on the TV, and accidentally chose a resolution unsupported by my TV. Now every time I plug in the VGA, that unsupported resolution is saved and outputs it, even though it doesn't work, and I cannot change it into a resolution that works because I can't see anything! How can I reset the saved resolution?

Hey guys,

First of all I would like to say hi. Anyways, today I decided to give a try to windows 8. Installation was smooth but the only problem I am having is the color difference between my monitors.

I am using a Dell laptop, and external monitor Philips. At my laptop screen it shows the fish background, and other stuff blue. But my external monitor shows the same fish background as cyan. Same for taskbar.

I checked color profiles, I checked calibration but nothing helped. Win 8 installed all the drivers automatically and it says Ati Mobility Radeon HD 5000 series (Engineering Sample- WDDM v1.20)

I couldn't be sure about the real cause of issue, so I didn't installed the Ati drivers. So what can be the reason for this weird color problem?

Note: Everything is fine on Win7.

Okie dokie. I just bought a Radeon x1600 512mb AGP graphics card today. Came home, installed it, and tried to get the dual monitors goin, seems easy 'nuff right? OH NO. NOT WITH ME. :-/ SO. I did what all the manuals say and go to the display window and settings and extend the desktop over. Then I go into the ATI CCC and make sure its activated there. La-di-da no bueno. So I reboot. Maybe thats what it took right? Well kinda. I started feeling good when both screens came up and started showing all the tests and such of the bios loadin and stuff being detected. However, when it came to the windows login screen the secondary monitor just went black. It didnt power down. Just went black. Says its still getting a signal. I try changin the settings to clone, didnt help. So i rebooted again and the same thing happened. I check to make sure the settings we're still good and active, they're fine. If I switch the display mode so the secondary BECOMES the primary display y'know? Then my original primary shows what SHOULD be on the secondary monitor (no taskbar, no icons) but the secondary monitor (now the primary) still is black. So I cant find anything to fix it!!!! AHH. Also im pretty tech-savvy so don't be gentle . Usually I can figure these things out easily.

Thanks in Advance.


A:Radeon X1600 Dual monitor-ing

Same Exact Problem!

I am having the exact same problem. I have a Dell XPS 410 and got this video card from Dell. They won't support it because its not their card. Can't get any help from Vision Tek either - they send you to Dell.

My main monitor is a flat screen digital and my secondary monitor is a flat screen analog. At first I thought it might be that the analog cable just didn't like using the analog to dvi adapter, but after switching the cables around the other monitor went black.

Have tried every possible solution I could think of, but nothing works. If anyone has a fix for this please let us know! I am guessing its a driver issue.

A:Radeon 7K Dual Monitor Graphics Card - HELP!!

Hi Folks,

I am trying to set up two monitors and here is my situation below. Any help would be greatly appreciated.

At work I have a slim tower PC - Dell C 521 with Windows Vista SP1. It works fine. I have received two older but good Dell E197FB monitors that only have VGA connections.

The video card in the machine is an ATI Radeon HD 4350 ( 512 MB ). It has two connections - one DVI and the other HDMI. I was able to get one monitor up and running by using a cable that has a VGA connection on one end and a DVI connection on the other.

But what do I do to get the other VGA monitor hooked up to the HDMI??? I want to use these two monitors to share or extend my desktops.

I did buy a 10.00 VGA to HDMI cable but that didn't work at all and a guy here said that probably wouldn't be enough to get this working.

Any advice would be appreciated.

Thanks - jg1234

I'm really hoping someone could shed some light on this.

I have one small monitor hooked up through DVI - works fine.

Then I have a Sony Bravia 42" HDTV hooked up through VGA at the same time in extended mode - the screen resolution options dont show 1920x1400, it only goes up to 1600x1200.

I'm using1360x768 now and it works but I have to zoom in on the picture. How I can I get 1920x1400 to show up in the resolution options? Seems like this should be straight forward. Messed around in the ATI Control Center with no luck.

When I had vista installed, hooking up the same TV through VGA was no issue.

Thanks in advance.

We are having problems on a Dell Vostro 230 desktop with dual monitors with Sapphire ATI Radeon HD 4350 graphics card.

Dual Boot (2 HDS) 32bit and 64bit Windows 7.

2 Monitors connected to the card:

- Monitor 1 LCD 20" Monitor via DVI lead (set as Main in windows & ATI Catalyst Control Center). This is only Monitor 1 when the HDMI is not connected.

- Monitor 2 is via HDMI and this is a 22" TV. Monitor 2 is not always turned on but this monitor controls monitor 1 depending on the setting in Windows Screen Resolution option (right click on desktop).


1) When I connect the HDMI lead the main monitor that should be 1 (DVI), now becomes monitor 2 and the HDMI TV takes over as Monitor 1. Although in ATI Catalyst Control Center the DVI remains as monitor 1 like it should.

Does this suggest that Windows is controlling the Graphics Card / ATI Catalyst Control Center and not vice versa.

Q: Is there a way for the ATI Catalyst Control Center to take full control and control Windows Screen Resolution settings so the HDMI monitor will remain as monitor 2 at all times when connected?

2) Because the HDMI TV takes over as Monitor 1, it controls what I can and can't do with the DVI main monitor. For example I have to keep the desktop as extended or my monitor turns off and the desktop and icons moves over to the HDMI TV.

Please detail any fixes or things we can try. Totally lost and perplexed.

Any help appreciated.

Hello guys,

- Windows 7 Pro 64 Bit

Both are 22" monitors. They both have a VGA, DVI, and HDMI plug in option.

- 1 HDMI to HDMI
- 1 DVI to HDMI

I am using a 22" screen for my primary screen and the laptop lid open for a secondary screen. The main screens resolution is 1680x1050, I can set it to anything I want and it's always using the full screen. The laptop screen on the other hand will only use the full screen if it's at 1400x1050 resolution (max for that screen, IBM Thinkpad T43). With the large 22" screen I have no trouble reading the screen at high resolutions, the screen is huge, with the little 14" screen though I have to strain to read the screen at 1400x1050.

The problem is when I set the laptop screen to anything lower than 1400x1050, it uses less of the screen. Preferrably I want it at 1280x1024 or 1024x768 (I dont know which I want yet as I can't see the freaking screen at that resolution). At 1280x1024 for instance the useable screen is just a box in the middle, so the "1280x1024" is still barely readable for me cause it's shrunk from full screen, plus it's just annoying only using a portion of the screen.

I have played with the ATI Control Center, the Thinkpad display settings and windows display settings and just cannot get this thing to go full screen at lower resolutions when docked and using the external monitor.

Anyway to resolve this?

Recently i tried setting up a secondary monitor under the setting of "Extend my windows desktop onto this monitor". Immediately my secondary screen showed that it was receiving input but the screen remained blank. The backlight turned on I am able to scroll my mouse over to the secondary screen(I cannot see my mouse on the secondary screen but it leaves my primary one and takes several seconds for me to scroll back implying it has moved on to the second screen). When i check the status of my screens in the display settings or my ATI Control Center it tells me that both screens (and adapters) are enabled and working properly.

This is definitely not a hardware problem because when i switch screens the same problem happens where my primary screen works but my secondary only glows and remains blank.

I am using Windows XP Professional SP2, with an ALL-IN-WONDER 9600 series graphics card. I have downloaded all the latest drivers from the ATI web site.

Okay so.. I just got another Really really nice 19inch LCD for free, and I figured that it would be a good compliment to my 22inch widescreen. So I started looking into it.

I currently run a (PCI) GeForce 5500FX series card and have my Widescreen hooked up to it.

I scoured the internet for information, and the general concensis is that. It's completely possible to run 2xPCI video cards, and that it is possible for them to be different brands.

So then I decided to go diggin in the closet and find my old video card. A Raedeon 5200 (PCI) made sure it was all clean, turned off my PC, stuffed it in it's own PCI slot, and fired up the Computer. (I realise this card is a bunch of Crap .. I don't need it to be good, just handle the second monitor)

Everything works fine, All my programs load, my Virus scanner, MSN, the Nvidia card.. Until.... the little window pops up that says "Windows has found new hardware (VGA)" or something like that .. and everything freezes.

So my question is .. Why? .. and can someone help me make this work ? ..

and before I get the typical answer .. No .. atm I cannot afford to upgrade anything in my pc. Trust me .. I want to, but that's not an option right now.

Thanx in advance.

Interesting, it doesn't do it anymore , only did it when i was using XP. But safe mode is always the best option. Also you have 2 older cards, you may want to install the 81.98 drives for both video cards.

I have only built one computer and it was run with an ATI card and using catalyst, I was able to control the placement of dual monitors with ease. I just upgraded to an Nvidia card and found it to be impossible to put the second monitor to the left of the primary monitor, this is important for my setup. After some searching I found Ultramon, which allows me to do this. Right now I am using it in trial mode. The trial will end some day soon. Are there free options to place my monitor where I want it?

I'm using a T430s and a mini dock plus series 3. This is the dock with the dual DVI, dual DisplayPort, 1x VGA. I do not use the laptop's built-in screen; just the 2 external monitors. Intel HD4000 graphic chip and Nvidia Optimus/ I previously had 2 20" monitors with a 1680x1050 resolution using DVI-to-DVI. They both worked fine. I upgraded to 2 24" monitors with a 1920x1200 resolution. The laptop is not recognizing the second monitor. I have tried:dual display port (dock side) to mini display port (monitor side): only 1 monitor recognizeddual dvi (dock side) to HDMI (monitor side): only 1 monitor recognizedI ruled out monitor and cable problems by swapping...each by itself works fine. Looking up specs, I believe this resolution should be supported by DP or DVI. Can anybody confirm that this is a supported config? Any ideas what is wrong? UPDATE - I did try 1 DP/mDP and 1 DVI/HDMI: this does work. However, its not an ideal solution because it would interfere with the monitors ports which I want to use for a second PC. UPDATE 2 - OK, now I am beyond aggrivated. I also have a support ticket w/ Lenovo where they suggested switching to Integrated Graphics only in the BIOS. I tried that, no luck. After changing that setting back, i tried to get my 1 DP / 1 DVI working, but now it would not recognize dual monitors. ??? After some testing, I'm finding that the -only- setup that works is the following: Dock DVI port 1 to Moni...

A:Second monitor not detected: T430s with Mini Dock Plus Series 3 dual external monitor

Fixed; was a driver issue. Problem seems exclusive to a Dell u2415 on DP port 1 only of the dock or to the laptop's DP port (at least for the couple monitors I tried). It's possible it could affect other monitors. My starting point: / (Nvidia /  Intel) The latest driver from Lenovo is / I'm not sure how i have a slightly newer Intel, but that's what it was. I couldn't install the Lenovo driver. I also couldn't install a newer driver from Intel ( In both cases Windows or the Intel installer stopped me saying the mfr provided the drivers and that the installed version was up to date. I worked around by first rolling back the Intel driver. The manual (.zip) install of the latest intel driver worked. This immediately fixed the Dell u2415 on DP port 1 and laptop's built-in DP port.

I recently got a monitor from one of my friends saying that it was broken. Its a Dell 19in LCD. I have my main monitor a 22in Samsung wide screen So i just plugged it into the second DVI slot on my graphics Card. When i went into the display config i set up dual monitors just to see if it was working. The dell monitor would blink up then quit on me.

When i was messing with the Display settings I made the Dell. Not my Samsung the Default Monitor. I unpluged the broken Dell and restarted. Now my computer regognizes the Samsung as the second monitor and it just shuts it off and recognizes nothing as the main.

I managed to get it into safe mode and it recognized the samsung but every time i try go back to Normal Start the screen is blank.

How can i get it to recognize the Samsung as my main?

The Issue: Dual monitors, secondary stays in D-VID Power Saving Mode and goes to black and flashes the standby light.

Monitor Model: LG 24'' IPS LED D2343 (CINEMA 3D)

Was working perfectly less than 24 hours ago, upon boot up this issue arose, attempted fixes to follow:

Basic Fixes Attempted:

1. Classic restart.
2. Removed screen connections, power and DVI.
3. Swapped Ports on the actual GPU between main and secondary monitors, main monitor fires up no problem.
4. Used the Monitor and cables with a different PC- The Monitor worked perfectly.
5. Reinstalled GPU Drivers.
6. Cleaned out the tower, dust etc.
7. Checked and re-checked as many settings as possible on W10, everything from Power settings to Display and Device management, this includes trying hot keys- like those used to project screens etc.
8. Checked windows Update- fully updated.

About 6 months ago i invested in a second video card to use with an old monitor and a new PC. After much trial and error i eventually got it all working.

A couple of days ago i re-installed windows however and therefore all my settings have been reset and am now havein problems, and if i remember rightly the same ones as before. But for the life of me i cant figure out how to solve them this time round. So any help would be appreciated.

Spec -

2x plug and play monitor (almost sure it has nothing to do with these so wont add details)

1x Nvidia Geforce FX 5200 (AGP) with fully updated drivers (from manufacturers website) (the monitor off this video card works fine)

1x ATI Radeon 7000 (PCI) fully updated drivers (without catylist command centre however due to some installation problems. I had these before when both monitors worked fine..just the drivers) - Problematic monitor

Bios - Dell Computer Corporation A12 (newly updated) (I heard somewhere that this may have an effect).

The Problem-
On my second monitor (Radeon 7000 (PCI) whenever i try to move a frame, scroll in IE etc the refresh rate is appaling. Entire lines get moved at a time.
The only time the refersh rate does not slow is when moving the mouse and scrolling through files in c drive as far as i can tell. If i switch my primary monitor to this one and stop the monitor 'extension' it still flickers. Ive checked my monitors by changing which card they use and as expected, th... Read more

A:Dual monitor problems- second monitor refresh times dreadful

Well, could be bad drivers... nvidia and ATI hate eachother, so I dunno why you got cards like that, could be a driver conflict from un-updated windows files, that is to say, uninstall drivers, update everything on windows, re-install newest drivers.

Running dual monitors in Win 10 and when going through the Color calibration steps on monitor #2 (Control panel / Display / Calibrate color) the settings stick as long as the 2nd monitor is active.

If I switch to single display (Windows Key + P / PC Screen only) then the 2nd monitor loses its color calibration. Also anytime I reboot my PC (Even if I have both monitors active) the 2nd monitor loses my calibration.

The 2nd monitor has a fairly strong bias for the color Green so I can always tell right away.

I'm probably overlooking something and was hoping someone might of dealt with this before

I recently bought a DVI cable to plug my external LG monitor to my laptop to run nVidia's DualView (stretch format) across the two monitors. I'm using a beta driver (169.04 from laptopvideo2go.com), and when I enter nVidia control panel and go into the setup additional monitors tab, it only lets me choose "choose only ONE monitor". So I did that just to test that my monitor was plugged in right, and it worked. So I KNOW that my monitor is working and is being recognized by Vista. But when going into display settings byt right clicking on my desktop, it also only recognizes 1 monitor. Is it my beta display driver messing my Vista up? Or what could it be?
Any help would be greatly appreciated

Thank you

A:Solved: Dual monitor in Vista not working. Only showing 1 monitor.

for drivers to work properly in vista i'm pretty sure you have to have signed drivers, since it's beta are you sure they are signed?

Whenever my computer recovers from sleep mode, or when the screensaver comes on and I wake it up, I find that all my apps are now on my main monitor.

Example: Google Chrome and Skype on Monitor 1.
Microsoft Word and MSI Afterburner on Monitor 2.

-computer sleeps/ screen saver turns on-
-I wake the computer up-

Google Chrome, Skype, Microsoft Word, and MSI Afterburner are on Monitor 1.
Nothing on Monitor 2.

Is it possible to fix this?

A:After dual monitor sleep recovery, all apps shift to one monitor

I've had dual monitors for years now and have never had this problem. But I also have no screen saver.

If you put your system to sleep why would you want a screen saver? All that does is keep the system active and running - which is the opposite of what sleep does.

Remove the scree saver and see what happens.

I've been running a multi-monitor setup for a while now, with an ASUS VG248QE 144Hz monitor as my main, and one or more spare monitors as secondary displays. I've set the ASUS monitor to 144Hz without issue in the past, while the other monitors stay at 60Hz.

The other night, Windows wanted to update. I figured it was the usual patch session, so I let it do its thing. However, after restarting my computer, I noticed that my ASUS monitor would only operate at 144Hz if it was the only monitor plugged into the system. When I try to set it higher in the Nvidia control panel, it just reverts back to 60Hz after applying changes. I updated my graphics drivers (though I was only one version behind) and even sought a special ASUS driver for the monitor to resolve the issue, but nothing has helped.

Did Windows recently add a forced refresh rate sync between all monitors recently? If so, that really sucks because I only own one 144Hz monitor.

A:Dual monitor setup locks 144Hz monitor at 60Hz

Are you sure the other monitors are independent (dual or multiple mode) rather than cloning the main monitor? If they clone the main monitor, then this explains the 60Hz refresh rate, as all settings (resolution, color depth, refresh rate) should be common for all monitors and the others can only do 60Hz.
