1   / Monitors, HDTVs, etc. / Seiki 42" 4K SE42UMT Custom Resolutions on: December 19, 2015, 07:59:42 PM
After setting a custom resolution 2560x1440@60Hz for Seiki 42" 4K UHD LED TV / monitor (model SE42UMT) in AMD Control Center, the desktop looks overextended beyond its size and the extended portion overlapped (http://oi66.tinypic.com/34t4l6f.jpg) on one side. So part of the desktop background picture and open app windows visible on the right side are overlapping again on the left screen side. The display is connected from AMD FirePro V4900 video card's DP1.2 via DP1.2-to-HDMI1.4 4K passive adapter to HDMI2.0 monitor port. I tried various TV aspect ratios, but the problem stays. Selecting GPU Scaling instead of Monitor Scaling method doesn't change that. Any suggestions, how to fix that?

Another question: after testing AMD Control Panel Scaling Options with this monitor by dragging Underscan-Overscan slider, the monitor's entire visible screen area became a little smaller, it doesn't extend to the plastic bezels anymore. Resetting GPU and display settings to factory doesn't change that. How to revert to the original 42" screen size?

Is their an "Active Off" keyboard shortcut in Windows or any monitor control package? Can I make such a shortcut - how? Or the only way to switch to "Active Off" is sending PC to Standby or setting shorter time period for Windows Monitor Power Off Option on mouse inactivity? I want to be able to switch the monitor to "Active Off" any time and wake up any time, while the PC is downloading large files or performs longer tasks.
3   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: October 25, 2010, 10:20:55 AM
From your reply it sounds that the reason for loud clicks is the monitor don't wait 5 sec before switching to Active Off, thus confusing power saving with resolution change. If that's the case, why it doesn't happen in Ubuntu, where the monitor softly blacks out and them switches to blue screen Active Off mode? If in Ubuntu GPU driver does not terminate horizontal *and* vertical pulses at Standby, why the monitor screen turns black before blue? I'll try this soft, thanks.

P.S. I did try the EnergySaver. It seems to work only when API mode is selected, and it clicks softly in that mode on Standby, with screen going black right away, and then blue immediately. It doesn't send the PC to Standby, only the monitor - that's the difference btw EnergySaver and using Windows Standby button. Where I can get Controller ID and Base Address from for my GPU? May be changing these settings would allow to work in V/H Sync mode? How to uninstall it?

One way to fix the issue of low resolution picture on this monitor, when using a card that can't read complete EDID from it, is to follow the MS article: How to Use an INF to Override the Monitor EDID.You may want to download EDID-Override Driver for this monitor, I made with MonInfo after obtaining complete EDID from L2410NM HDMI port via a proper GPU card (the factory monitor model # is WDE5180). Open Windows Device Manager, and update driver for L2410NM, pointing to that .inf file. After reboot it should work OK via HDMI on any supported resolution with your GPU card, but I suggest using its native 1920x1200. Keep in mind, in my experience some GPU cards ignore a LCD monitor's driver specified in Windows Registry, and regardless obtain EDID (some incorrect or incomplete) from the monitor directly at each PC boot. In this scenario what can help is either using a different GPU card (ATI3870 works OK), or a different (analog, DSub or DVI in this case) GPU video port.


Is there any way to find out, if a video card or its current driver correctly support LCD Monitor's Active Off / Very Low Power Mode? Any soft to verify it or adjust such driver setting? I suspect, loud clicks on Power Off with this monitor result from GPU driver incorrectly entering Active Off (the only PS mode this monitor supports), or the monitor incorrectly interpreting loss of signal as "Change Resolution". I noticed, clicks on PC going to Standby only happen in Windows 7 and XP, but not in Linux. This clearly points towards GPU driver - monitor interaction. Any thoughts, how I can use this discovery to stop clicks at PC sent to Standby? I tried to uncheck "Active Off" in EDID and updated the driver, but it gave no effect on clicks, since I assume the signal from GPU must be switch off anyway, when going to Standby. Should there be any difference in GPU video signal shut down depending on monitor's Active Off checked or unchecked in EDID - what exact difference?

The MonInfo Report was of course real time. Pls check your e-mail.
6   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: June 08, 2010, 10:06:25 AM

Before I tried MonInfo with my Win 7 laptop and Nvidia card. It queried the L2410NM display and show that there is one extension block. But the block appeared to be empty, all zeros in the EDID (see the 1-st post of this thread). Now I tried MonInfo on my desktop PC with Win 7 and ATI 3870 card with the same monitor. After querying the monitor for awhile, MonInfo shown a complete EDID with an elaborate very detail 1-st extension content. That was a surprise! Respectively, the monitor works normally with the PC. Both times it was connected to computers via same HDMI port, but in case of the ATI card via an HDMI-to-DVI adapter, since the card has only 2 DVI ports.

Does that mean that MonInfo in fact doesn't query monitors directly, but instead uses the GPU driver's ability to get EDID info from the monitors? My Nvidia card driver was unable to get the full EDID (may be because its written in 2 EEPROM sections?) from it, and neither MonInfo. With ATI it was wice versa. If that's the case, how reliable MonInfo is as a corporate assets info tool?

With regards to Monitor "clicking" issue at going to Standby, I was able to eliminate this by switching Off Power Management features in my MoBo's BIOS, and using Win 7 Power Management features instead. Still the monitor has no Standby ability, and goes to blue screen at Standby.
7   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: June 01, 2010, 04:41:28 PM
This is an old laptop, I don't think its monitor has EDID, and it doesn't have any means to communicate such info to the laptop either. Anyway, I found a registry string with its correct ID in Registry backups.
8   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: May 30, 2010, 06:43:12 PM
Thanks. I looked at brief descriptions of the standards you mentioned, and still try to guess what exactly can cause such clicking sound at going to sleep? Even if the monitor misinterprets the PC signals, what would be the source of such sound?

I know, PowerStrip is a popular program, but I have some concerns with it. I first tried it on my old Win98 Sony laptop to see how it works, while switching btw internal and external displays. I don't know what went wrong, possibly a bug in PowerStrip, but eventually it wrote the ID data of the external monitor into the Register instead of my laptop's monitor. It would be easy to fix having EDID data, but the P2 laptop is old, and its monitor doesn't have any data exchange with the laptop. So, I can't identify my monitor anymore in Windows, there are no traces left what's it model and make, etc. It still works OK though. Since PowerStrip is advertised to work with every Windows version, you need to incorporate means to prevent such things.

Speaking of which, can you suggest any possible way to get my laptop monitor's ID back?  Roll Eyes
9   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: May 28, 2010, 09:01:10 AM

I followed your advice on trying to get the monitor working first in native resolution without changing EDID. It didn't work out when connected to my laptop with Nvidia card, but it does work almost normally with a new Win 7 desktop with ATI Saphire 3870 GPU card.

When I tried to connect it to the laptop, the screen resolution was awful, and any attempt to change the resolution resulted in loud clicks inside the monitor, as if a manual switch was clicked, or a short capacitor discharged. When connected to the PC, the monitor works at 1900x1200 native resolution, but for some reason at 59Hz instead of 60, despite System Info tools show 60Hz as its native resolution. When I switch to 60Hz, at restart it reverts to 59Hz. Also, this monitor clicks every time the PC goes to Sleep, or when auto switched Off at shutdown or reboot, it sounds like a capacitor short discharge. It doesn't click though at wakeup or boot. I'm concern, if its caused by the monitor's PCB design or manufacturing defect, it'll stop working soon, as the cap gets damaged eventually. I did notice that the PC switches it Off sort of abruptly (probably in a wrong way), while the monitor's own On/Off Button turns it Off softly and quietly without any sound.

On the other hand, the sound may be caused by a PC switching to an unsupported resolution at going to sleep or reboot - can it? I know, you guys are monitor control experts. What's the cause of such behavior in your opinion, how to troubleshoot it, and can it be fixed by correcting the EDID in Registry or any other means?

Another issue is that this monitor doesn't support Standby natively (or this function is not activated in firmware), it switches to a blue screen with HDMI logo instead when the PC goes to Sleep, possibly because it's design was copied from a larger Westinghouse TV Monitor. Is there any monitor control utility, that can compensate for this deficiency, making it go to Standby softly instead of blue screen? Btw, why you don't work with Westinghouse on their monitors support with your products?
10   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: May 23, 2010, 10:09:26 AM
This is an example for indexes 64 and 16, I tried:

CE video data (timings supported)
    1920 x 1080p at 100Hz - HDTV (16:9, 1:1) [Native]
    1920 x 1080p at  60Hz - HDTV (16:9, 1:1)
    NB: NTSC refresh rate = (Hz*1000)/1001

But, to be accurate, I tried higher indexes now, and it just shows highest supported by the monitor as per CEA-861E standard short resolution instead:

CE video data (timings supported)
    "1920x1080" 148.500 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync [Native]
    1920 x 1080p at  60Hz - HDTV (16:9, 1:1)
    NB: NTSC refresh rate = (Hz*1000)/1001

Still, 1080p@100 seems to be not in the standard as per EDID Wikipedia article I relied on. Or this article isn't accurate? I guess, I didn't check further the 1st time around, sorry.  Roll Eyes

Another question would be, if the monitor's original retrieved EDID is V1.3, and it supports HDMI 1.2, would it be wise to convert it to EDID V1.4 before creating .inf EDID Override file, since that version seems to support HDMI 1.4 ? Or these EDID versions are backwards compatible anyway, so no miscommunication btw devices via HDMI can occur?  Huh
11   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: May 23, 2010, 07:45:38 AM
Actually I was asking, what value is used by MonInfo (since there is no such official value in CEA standard yet) to indicate support for 1920x1200p@60Hz ? I was also asking, where did you get these reserved range 64-to-127 values from? We all know that often standards are created to reflect and "mandate" established by leading players practices. So, there would be nothing unusual for monitor device makers to have there own SVD Tables in the above reserved range. It would be natural for MonInfo to use such manufacturer SVD data in lieu of an updated standard to ID these devices, as it does. Hence, why would that be a problem to give that index number?  Grin
12   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: May 22, 2010, 12:57:35 PM
MonInfo is advertised as a tool to manage corporate display device assets. Why then you refuse to answer basic product questions, like giving a hint on what source its SVD Table for 64-to-127 index range, reserved in CEA-861-E standard, is based on? Pls help me understand, how I can recommend this tool as accurate and reliable to my corporate boss? You seems to forget that any of this forum visitors can become your loyal customer, unless you repell them out.

Thanks for your help anyway!  May be I can help you in return: Best way to detect EEPROM size.
13   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: May 22, 2010, 08:02:25 AM
EDID Overwrite can't help to use the same monitor with stand alone devices that read SVDs from EDID CEA Extension's VDBs instead of resolution values. I'm surprised, you refuse to give any hint on any practice based source of SVD Table for 64-to-127 index range found anywhere.

With regards to writing EDID in Powerstrip, I found this: "If you select a base EDID bloc, it will be written to the first 128 bytes. If you select a DI, DPVL, LS, CEA or VTB extension bloc it will be written to the second 128 bytes. No other segment or extension blocs are supported. Do NOT attempt to write an extension bloc to a 128 byte EEPROM or your base EDID may be overwritten by the extension bloc."

What software would you suggest to query a monitor's EEPROM size?
14   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: May 20, 2010, 07:30:33 AM
What secret you can reveal by giving Short VID for 1920x1200p@60Hz ? I can find it anyway by trying all VIDs in MonInfo withing 64-to-127 range, but its time consuming given extreme inconvenience of MonInfo not saving the last used folder.  Since these VIDs are not in CEA-861-E standard, what approach did you use to assign a VID to a particular resolution value? This is important for users to understand, since the attached devices are also expected to use the same VIDs to identify matching resolutions, so their VID Table must match yours.

I don't think its a good idea to impose conditions on users of Entechtaiwan software, they must follow to receive product support. Info reach content will only attract more customers to your website, thus generating more sales. You may be surprised to learn, some monitor makers never heard of your products and their capabilities, as I found. So, more factual info is always relevant.

I doubt that newer monitor's EDID can be safely used in older models of the same make, as newer monitors often use different display panels with different timings. Am I wrong?

There are many EDID examples posted on the web. What software package can be used to copy and paste an EDID Row Data report posted as text on a webpage? OK, I found one: EDID Editor. It was also posted that 128 Bytes limit EDID Override bug in Win7 was fixed.

Can Powerstrip determine and show to a user a monitor's EEPROM size to find out if its sufficient to write an EDID? Or it just writes next blocks over the previous ones, if there is no space available, thus increasing the chance of making the monitor unusable with more devices.

Could you please answer the above questions about your products capabilities.
15   / Monitors, HDTVs, etc. / Re: Westinghouse L2410NM on: May 19, 2010, 08:07:06 AM
Thanks Ashley!

The above link suggests to get rid of the CEA extension, but also confirms basic L2410NM monitor's EDID was good, they just removed the extension number. It looks like at the time of coding EDID the manufacturer didn't have software able to write an EDID file with Extensions, so they just listed Ext.1, but didn't actually add its description. Westinghouse tech support said to me "No updated EDID available", probably to avoid possible warranty claims. Is PowerStrip capable to write updated EDID to this monitor, and how to find out if its EEPROM can hold 256 bytes (2 EDID blocks) or more?

Will try your suggestion first, but still want to get audio via HDMI later. What index number (Video ID Code) among reserved 64-to-127 in CEA-861-E standard corresponds to 1920 x 1200 @ 60 Hz in MonInfo's Short Video Resolutions index table? I wanted to add this resolution as native later to CEA Short Video Descriptors.

Any comment on the issue with Windows 7 storing only 128 bytes for EDID in Registry? What are the consequences, if the monitor's own EDID is wrong?
