Attention Eizo EV2736 Owners. Does your input signal match your resolution?

Could all Eizo EV2736 owners please select all of the following resolutions then let us know if you have any mismatched input signals.

I discovered one mismatched input signal among the following five supported resolutions plus a mismatched input signal for the "unsupported" 1600X900 resolution.

To view your input signal. Press "Enter" on your on-screen-display and a menu will appear, then select "Information".

Please use a DVI-D dual link connection.

Supported Resolutions............... Input Signal
2560 X 1440.............................. 2560 X 1440
1920 X 1080 ............................. 1920 X 1080
1680 X 1050.............................. 1920 X 1080
1280 X 720 ............................... 1280 X 720
800 X 600 ................................... 800 X 600
_____________________________________________________________
Unsupported Resolution............. Input Signal
1600 X 900 ............................... 1920 X 1080

Also note the following two confirmed oddities:
Your Eizo Flexscan 2736 Manual (page 13) does not list 1600X900 as a supported resolution, despite 1600X900 having a 16:9 aspect ratio. When I asked Eizo tech support (USA) why this was so, I was told that either this was a typo in the manual, or if 1600X900 is truly not a supported resolution then only the builders in Japan would have the answer for this.

The other oddity listed in the manual is that 1680 X 1050 is listed as a 'supported' resolution, despite 1680X1050 not having a 16:9 ratio. Either the manual typed 1680X1050 instead of 1600X900 or only the builders in Japan know why?
Unusual for sure isn't it? And isn't it also odd that it is these two resolutions (1680X1050 and 1600X900) that have a non-corresponding input signal.

Hello Supersnake,

Looks like You and I are the only owners of the EV2736 on this forum, as you have not had your post answered for quite some while. I have been away for a month and have not had the chance to answer your post myself until now.
I can however confirm what you have written in your original post regarding the mismatch of signal vs information. Here is my results:

Supported Resolutions............... Input Signal
2560 X 1440.............................. 2560 X 1440
1920 X 1080 ............................. 1920 X 1080
1680 X 1050.............................. 2560 X 1440
1280 X 720 ............................... 2560 X 1440
800 X 600 ................................... 2560 X 1440
_____________________________________________________________
Unsupported Resolution............. Input Signal
1600 X 900 ............................... 2560 X 1440

Now, even thought the information menu claim that my input signal is 2560x1440 in either of the mismatched modes above, I can clearly see that it isn't 2560x1440 as stated in the info menu. The resolution looks correct in regards to what I have chosen, even though the information claims otherwise.

I am running windows 7 with an ancient ATI HD4850 card that I had to put into my rig when I bought this display, as it supports the 2560x1440 resolution that my integrated gfx on my cpu didn't. So I have to live with this ancient card til I upgrade later on this year.
 
Good to hear from you Falconetti! I was all forlorn that my post had drifted away never to draw a response {:>

Have to head for work now, in around 12 hours I'm going to return to this thread and post my very interesting followup with Eizo. Hint, it was good.

Looking forward to it!
 
Over the course of 3 weeks I collaborated with Eizo Tier One tech support and tried their various recommendations which were: connecting their supplied DVI-D dual link cable to each of my two video cards. When that didn't resolve the issue I performed a clean uninstall (using Windows + Driver Sweeper + another utility) of my up-to-date NVIDIA drivers - then reinstalled their most current drivers. When that didn't resolve the problem I tried some back dated drivers. That didn't work so I reverted back to the most current NVIDIA drivers. I then tried a different cable without success.

Tier One then escalated the ticket to a tech at corporate level who asked me to connect my monitor to another computer. I transported the monitor to my friends house and connected it to his one year old computer (Windows 7 with an NVIDIA GTX 580 ) --> however the same incorrect input signal readings remained.

At this point Eizo declared my monitor as DOA and authorized an RMA for new replacement. Two days later a brand new monitor arrived. However, it had the exact same incorrect reading of input signal values as did the first monitor. Bottom line to all this is I returned the replacement monitor and kept my original monitor. I suspect that for whatever reason all EV2736's must be having a mismatched readout of input signals to certain resolutions.

I can rationalize all this as just a peculiarity with this model. As you have told me the resolutions looks correct in regards to what I have chosen, even though the input signal information claims otherwise.

Am still impressed with the image quality, the lightly applied anti-glare, and the refreshingly pleasant non-overly saturated sRGB native gamut. Am keeping it.

Thanks for your responses Falconetti.

Hello again Supersnake and thank you for your informative update !

So this have been tested on a total of 3 computers. We all share the same OS, while you and your friend have a GTX 580 and I have a HD4850. You and your friend share the same mismatched res/signal while I don't. You had 2 mismatches out of 6 tested that claimed the signal was 1920x1080, while I had 4 mismatches that claimed the signal was 2560x1440.

Seem to me like a driver/gfx problem in regards to this display. Although it does not really bother me as the chosen resolution is correct it still makes me curious if users with newer gfx cards experience the same faulty information in the display menu. I think I will take this test to the Swedish forum where there are plenty of owners for a potentially bigger test group.

Il get back to you with the results later on!

Chances are the monitor is reporting the correct resolution and that the video card is scaling. The video driver will always add certain resolutions like 1680x1050 even if it's not listed in the monitor's EDID, and the video card will scale any resolutions that aren't listed in the EDID to the next highest resolution, even if GPU scaling is not enabled. If GPU scaling is enabled, then all resolutions are scaled to the native resolution. You can control what resolutions are sent to the monitor by using my Custom Resolution Utility, which will create a software EDID override.
 
ToastyX,
Thank you! After reading what you wrote it all becomes clearer now.

Falconetti,
Look in your GPU control panel, it appears that you have your GPU set to Perform scaling on GPU. If it is, then your Information Window for the 1920X1080 resolution would be expected to readout an Input Signal of native 2560 x 1440 (not 1920 X 1080).

Supported Resolutions............... Input Signal
2560 X 1440.............................. 2560 X 1440
1920 X 1080 ............................. 2560 X 1440
1680 X 1050.............................. 2560 X 1440
1280 X 720 ............................... 2560 X 1440
800 X 600 ................................. 2560 X 1440
____________________________________________________________ _
Unsupported Resolution............. Input Signal
1600 X 900 ............................... 2560 X 1440


Reviewing all that has taken place

I, not having the knowledge of ToastyX, couldn't figure out why the Information Window showed the Input Signal differing from the selected resolution and I thought that something may be wrong. For that reason I contacted Eizo last month and they were very receptive to assist me - they even replaced the monitor, which in retrospect appears to have been unnecessary.

Since I am running no programs that require me to override the EDID, am presuming that I can let my monitor or video card handle any scaling should I ever find a need to run some program or older games that might benefit with scaling. Otherwise, I'll always have this monitor run native resolution.
Cheers and thanks!

Yes it makes sense, thanks ToastyX for clearing things up !

Supersnake, I'll have to check it out and get back to you hopefully within a week. I was only home for a short stint before I had to leave again. Catch you later !
