I can't select the DVI source input on the monitor front panel

I'm trying to select the DVI source input on the monitor front panel but it will only move thru the source inputs 3, 4, and 5 which are s-video, composite, and component. The inputs 1 are 2 are d-sub and dvi. I would like to use DVI. I'm trying to do this in order to get the 1900 by 1200 resolution offered by this monitor. It worked in the past and then suddenly I am having problems with this. Thank you. Kerry

The logic board is probably bad. Check out the site they have installation video on changinging out the board and also sell all parts for that monitor.

Re: I can't select the DVI source input on the monitor...

Video card in the monitor sounds to have failed. It dosn't take alot to short them out these days.
Try the analogue port (make sure everything is off when you connect it up) and then see if you get to access it from the menu.
Sometimes these monitors are a little fussy about selecting things that it didn't detect as valid when it powered up.
By powering up I mean from when you plugged power into it, not just turning it on with the power button.
It would need to be unplugged from the wall for about 5 mins to drain out the power that is stored in the main filter capacitor.

No signal

Press the Function Button to open the short cut menu. Locate the Input graphic and press the button for it. Each time you press the button, it will cycle between DVI and VGA input jacks. Allow a few seconds for the display to switch inputs. Make sure that cable is connected securely to the associated jack in the back of the monitor and the computer (or other source). If either VGA or DVI input is selected ,but the VGA and DVI cables are not connected, a floating dialog box indicates:

"No Cable Connect" or "No Signal"

How to switch from analog to digital mode

Any contemporary monitor is able to switch analog/digital mode automatically if connection from signal source to monitor is set up properly.

Connect digital output from your graphic card to DVI input of the monitor. Disconnect any other signal cables from monitor and switch on both devices (PC & monitor). Wait a while. Monitor checks its inputs and a activates digital DVI, because it is only one active input on it.

If none picture excluding error message of monitor is displayed, go through these steps:
1) Check whether your monitor is set for automatic input selection. If monitor buttons have no response try to use analog input to activate screen (any picture, desktop background...) and then get monitor menu access by pressing menu button.

2) Find out what connector type has your graphics card in PC. Possibilities are: DVI, HDMI, DisplayPort and some their options. See Wikipedia for connector look if you are not sure.
Remember that blue D-SUB (VGA) connectors are analogue and you cannot activate digital mode through analog VGA cable.

3) Use appropriate cable to connect monitor to PC.
Example: Your PC has HDMI output. Use HDMi-to-DVI cable. Your monitor input is DVI and common DVI-DVI cable is not suitable in case you have PC with the HDMI.
Note that DVI-to-DVI, DisplayPort-to-DVI etc. cables are available. You must buy right one.

Be aware that "Auto" button is inactive in digital mode of monitor.

Acer monitor no signal

If your monitor has various input sources, make sure it's on the correct input source in the main/input menu. If that's not the problem double check the cable for bent pins also make sure if you have a video card with DUAL dvi outputs that your using the correct one.. as the other one might be secondary and non-functional. It's possible but highly unlikely if you unplugged the DVI cable while the monitored was still powered on it could have damaged the video card of the computer or mainboard of the LCD monitor. When in doubt try another DVI cable if all else fails.. if you have another DVI monitor (thats a known good) try that also to make sure that the video card is not the problem.

Monitor wont come out of sleep mode

I'm guessing you are using a the VGA input of this monitor (the smaller "D" shaped connector with 15 pins) on the back. If not, and you are using the DVI input (larger white connector), then check your PC video output. I've seen this occur with HP monitors when they accidentally get set to "digital" input. Its easy to set that way (even by mistake), but not as easy to reset to analog (VGA). To do that, you'll need to find someone with a DVI output on their video card. Once you connect to a DVI source, the monitir will come on and stay on. You then need to go into the menues of the monitor, find the setting and change it back to "analog". After you do of course, you won't get an image on your monitor until you reconnect to an "analog" (VGA) source.

My viewsonic mo9nitor says analog not digital on

To clarify, you know that analog is referring to the VGA 15 pin video input, and digital is referring to the DVI video input, right? You can't have the digital video unless you use the DVI input, which requires a DVI output from your computer (and a DVI cord of course).
If you already knew this and you mean that it won't switch over to your DVI, then there could be several problems. Most of them being with your DVI signal source (computer). Try booting the PC with ONLY the DVI cord attached between the PC and the monitor. If you have a VGA cord plugged into either, UNPLUG IT FROM BOTH ENDS.

My monitor has gone blue, what do I do

Assuming the monitor is powered (if unsure, check the that power cord is connected to a live 120 volt source and the other end is connected to the monitor), check the data (analog VGA or DVI) cable between the monitor and the computer. Make sure the connectors are firmly seated in the respective jacks, and held in place with the retaining screws where provided.

If all four connections (power in and out and the data in and out) are satisfactory, check your monitor's input "source" selection. This may be selectable via dedicated "Source" button on the monitor or from the monitor's "Menu".

When changing the source input types with the button, it will usually take a couple of seconds before an image will display, so allow enough time for the monitor to respond to the change. If changing via menu selection, it may not change until saved or exiting.

If the monitor refuses to display, it may be an issue with your video card. In this case you could try swapping the video card or the monitor to determine which is the culprit.

I hope you found this Very Helpful and good luck!

Samsung T220HD - can't access HDMI input sources

If it like my monitor, same hookups as yours, then when you want to use the hdmi port you need to disconnect the dvi cable. The monitor cannot read from hdmi & dvi when both are connected, Try this & see if your PS3 works. Good luck.

Analog Dead/DVI OK

Sounds like the video controller board inside the monitor has blown a transistor. They are only about 3mm wide so not easy to spot even if you look closely.

It's a fairly rare fault, though not unknown to happen without reason.
