Solved samsung 2233 dos mode

June 29, 2012 at 06:07:55
Specs: N/A, N/A
It it possible to use Samsung 2233SW in anything other than native resolution?

Screen displays error message about using native res (1080p) for 1 min then powers down. This makes it basically impossible to use non GUI boot disks, set BIOS, install O/S, etc etc etc

I've spent hours trolling the forums, samsungs site etc etc but not found a solution

(Anyone suggesting drivers or desktop settings can fix a problem which occurs BEFORE THE OS LOADS should throw away their PC and buy an iphone)

You are confused about what 1080p means. That is the refresh rate, not the resolution. The native resolution for your monitor is 1920 x 1080.

Resolution is always described by two numbers. The first is the horizonal resolution, the second the vertical.

1080p is a HD resolution.

All graphics cards, chips in modern computers basically have two modes. The first is basic VGA or SVGA, which is used during the boot sequence. After the OS is loaded the graphics drivers take over and display whatever compatible settings you have made in the OS.

If you can't see boot disks, or enter the BIOS the issue is not the resolution.

Are you using an HDMI cable?

Are you using integrated graphics?

Are you connecting to a secondary port on the graphics?

Any chance you have the manual? It says it supports the vesa mode 640x480

Might be that it is set to av mode to match tv and that is why it is failing to work on pc text.

If your monitor model has both a DVI port and a "VGA" (Analog; d-sub, 15 pin holes) port......

- you probably can use one or the other of them to connect to video output from your computer(s), NOT both of them at the same time .

- in most, if not all, cases the DVI port on the monitor has only the pin holes for DVI-D use - digital video only - that applies to your particular monitor model - you cannot physically connect to that with a DVI-I plug on a video cable, or a standard DVI-I to VGA gender adapter, and you cannot get video from a VGA connection to that port.

ALL monitors display in a default VGA mode while booting the computer and in the bios Setup BEFORE the operating system loads.
You should ALWAYS have video while booting BEFORE the operating system loads if there's nothing wrong with the output of the video adapter you have the monitor connected to. That does not require any software on the hard drive and should work fine even when there is no hard drive installed.

- However, when you have a monitor that can be used with either an Analog or Digital signal, you MAY need to CHANGE THE INPUT SIGNAL TYPE to Analog or Digital in the settings on the monitor itself - in the OSD (On Screen Display) - to the other mode if the correct mode is NOT automatically selected by default.

- if you're using a HDMI port connection on a video adapter you may NOT get any video BEFORE the operating system loads !
See Side notes below.

(OtheHill said..

"Are you using integrated graphics?"

If your computer has more than one video adapter, if you have the monitor connected to a port for an onboard (built into the mboard) video adapter, usually that port will NOT produce video when there is a video card installed in a PCI-E X16 slot - only the video card installed in a slot (that has (a) port(s) in a slot space on the back of the case) will produce video - UNLESS your mboard's main chipset supports Hybrid video in which case the onboard video still works and the video card installed in the slot may NOT produce video by default until you change at least one setting in the bios Setup. If you don't know whether your mboard's main chipset supports Hybrid video - both the onboard video and the video on a card installed in a slot working at the same time if the video chipset on the card is supported by that feature - provide the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard.)

Samsung 2233SW
Quick Guide
http://downloadcenter.samsung.com/c...


Shows a DVI port and a VGA (d-sub, 15 pin holes) port. Some models may have only one or the other port.

I suspect your model DOES have both types of ports.

Excerpts:

Warning Messages

If there is something wrong with the input signal, a message appears on the screen or the screen goes blank although the power led is still on. The message may indicate that the monitor is out of sync range or that you need to check the signal cable

(Picture - example of a message on the screen.

Not Optimum mode.
Recommended mode **** x **** ** Hz
Analog or Digital in a box below that.)

Note - for models with Analog interface only (only a VGA port), Analog/Digital is not shown in the warning message OSD (On Screen Display).
....

I'm guessing that....
If the box below that message shows the opposite of the way you have video output connected to the monitor, you probably MUST go into the settings in the OSD on the monitor itself and change the input setting to that type.

NOTE that your monitor supports both of either a 50 Hz or 60 Hz AC power connection.
That's whatever the AC power uses where you're using the monitor. If that is not selected correctly automatically by default, you need to change that setting in the OSD.

"Are you using integrated graphics?"

All DVI ports for/on video adapters have the pin holes for a DVI-I connection, but that doesn't necessarily indicate the port is wired up to the video adapter to support DVI-I use.

If the DVI port is on a video card installed in a mboard slot, I've never come across and I've never heard of a video card's DVI port NOT supporting DVI-I use.

If your mboard has onboard video (a video adapter built into the mboard) that has a DVI port. in some cases, that DVI port ONLY supports a DVI-D connection (digital video ONLY).
If you install a standard DVI (DVI-I; male) to VGA (female) gender adapter in that port, you CANNOT get VGA video from that port.

OtheHill said...

"Are you using an HDMI cable?"

If you're using a HDMI port output on a video adapter and converting that to a DVI connection (all HDMI port outputs can be converted to a DVI-D output but NOT a DVI-I output) , we have seen that with at least SOME Samsung computer monitor models, and at least SOME Samsung TV models that have monitor input ports, that you will NOT get any video BEFORE the operating system loads in that case. There is NO workaround for that ! You have to use either a VGA or a DVI to DVI connection !

The Samsung 2233SW monitor has a "native" or "optimal" resolution of 1920x1080.

The two numbers are for the width x height of the display.
It has a 16:9 aspect ratio - the ratio of the width to the height of the display expressed in whole numbers = 1.777 (to 1) when you divide the first number by the second number.

In Windows, if you choose any other resolution the display will NOT look as good
the most noticable thing in common being the text on the scrren will NOT be as clear.

If you choose any other resolution....
Turn on Clear Type in Windows XP or Vista Windows 7 - makes type/fonts on LCD screens look clearer.
http://www.microsoft.com/typography...

If you DO choose another resolution, select one that has the same 16:9 aspect ratio, if you can, for a display that is proportioned correctly (not stretched horizontally or vertically) = 1.777 (to 1) when you divide the first number by the second number.

1080p -
p = progressive scan

That's different from 1080i -
i = interlaced - the odd horizontal lines for a frame are displayed, then the even horizontal lines for a frame are displayed, alternately.

Thankyou all for your replies.
Some great answers in there - it's on the internet so it must be true right?

It turns out that the error message itself is potentially misleading.
The problem has nothing to do with resolution, it's all about good old refresh rates...

The Samsung 2233SW just cracks it at anything over 60hz.
You can get rid of the error briefly by pressing menu buttons, but it'll still go blank before long

The manual only lists 11 possible modes, all 60 Hz approx.
but
-It will display unlisted resolutions without producing the error, provided set to 60Hz
-Set any of the listed resolutions over 60hz and there's that error message

The manual claims that it will work fine again over 85hz, displays the error but doesn't enter standby.
But at 70, or 75hz she's not happy

I haven't confirmed with Samsung directly, but apparently there is no simple workaround.

See response 3 !

The settings in Windows have NO EFFECT regarding whether you get video
while booting the computer BEFORE the operating system loads, but if your model has both a DVI and VGA port, you MAY need to change a setting or two in the monitor's OSD settings, and you MAY have another problem !

Other than those two possible settings in the monitor's OSD I mentioned,
- if you change other settings in the monitor's OSD to settings that can't be displayed in the default VGA mode while booting the computer BEFORE Windows loads, of course, you will get no display BEFORE Windows loads.

If you're not sure what you changed,
- load defaults in the OSD settings
- if there is a setting for the input type, make sure it's set to the type of connection you're usng - Analog (VGA) or Digital
- if there is a stting for the frequency of the AC voltage - that must be the same as your AC source is using.

- you MAY get no display before Windows loads if you're using a HDMI port output connection on the video adapter !

- Windows ignores the resolution and refresh rate settings the monitor's OSD has been set to and uses it's own Display settings for those.

If you always get video while booting the computer BEFORE Windows loads, but you get no video (other than possibly an error message from the monitor itself) in Windows AFTER it has started to load, that problem is EASY to fix.
I need to know your Windows operating system to point you to specific directions on this web site.

The horiizontal and vertical frequencies the the monitor's display supports are two very different things

Specifications. 933BW. 2233SW. 2233BW. 2433BW:
http://www.samsung.com/us/system/co...

Video Input Signal

30-81 kHz (H) / 56-75 Hz (V)

The vertical refresh rate is 56~75Hz.

You monitor model probably cannot display in Windows when the vertical refresh rate in Windows has been set higher than 75 Hz.
It may not be able to display anything at it's highest resolution(s) unless the vertical refresh rate is set to 60 Hz.

Apparenly your model is a cheaper model. I would not be surpised if it can't display at any resolution at anything but a 60 Hz vertical refresh rate.
...........

It's extremely unlikely but possible your monitor is defective. Try connecting it to a DIFFERENT computer with the OSD settings on the monitor set to default settings.

You were asked what type of connection you were using and you haven't responded.

1080p is the quality of the signal being sent to the monitor. That high of a progressive density is High Definition. I seriously doubt your "non GUI boot disks, set BIOS, install O/S, etc etc etc" are anything more than standard VGA files.

Ignore that message. I suspect that when your computer starts to boot whatever OS you won't tell us you are running, the display settings are not compatible with the monitor for whatever reason.

IF you are running windows then boot into Windows Safe Mode by tapping F8 at startup and check the settings for your display.

If you are running some other OS state what it is so I can move this thread to the appropriate forum.

Should be 1920 x 1080 @60Hz. See the link below for specs on your monitor.

Othehill,
The connection method is not relevant, but normally DVI-D single link. I can switch to analogue signal via 15pin Dsub, and duplicate problem.

No, 1080p is NOT the 'quality' being sent to the monitor when the problem is present.
My BIOS setup does not display 1080p
Text mode is not 1080p
No Windows installer I've ever met is 1080p

So when the problem is present the monitor is NOT at 1080p. This res is displayed correctly.

My BIOS is a standard VGA file?
Now I can't make any sense of that.
Sort of like being told 1080p being a refresh rate I guess.

Won't tell you what OS I'm running? Well it's completely irrelevant to the problem, but if you think it will help.....
-I'm typing this on a Vista install
-1 foot to my right is a box running Win8 preview, but normally Debian
-Netbook runs whatever distro i have installed that week, but dual boots XP
-The HP notebook runs Win7
-The asus box runs a heavily tinkered GeeX live from USB

So to answer, I run four versions of Windows (in a mix of x86 and x64) as well as at least two linux distros.

The prob is evident without a drive attached or OS loaded though, so don't see your point?

Never mind, I'll call our Samsung rep Monday morning and get him to follow it up for me. I'd just hoped somebody may have some clue about a workaround to use over the weekend...

Thanks everybody. have a good weekend!

Does anyone know a way to STOP the panel entering STANDBY MODE when receiving a signal between 61 and 84.9 Hz (vertical)?

I don't need an in depth discussion regarding the evolution of VESA standards. My first Microsoft OS ran on a Motarola 6809. My first hard drive was a used winchester. No I don't cut assembly level code in my sleep, or write my own device drivers, but I do have some level of knowledge.

I'm chiming in late, but after skimming the resposnses & checking the Samsung site, I'm a bit confused by the problem. The optimal/maximum resolution for your monitor is 1920 x 1080 @ 60Hz. But that is the resolution for Windows, not for the BIOS or boot disks or during the OS install. If you're having problems with the BIOS display, there is no setting you can change for that. The problem is either with your graphics card (or integrated graphics) or possibly the monitor itself. If the problem is duplicated when connecting monitor to different systems, then the problem is obviously with the monitor.

If doing that does not ALWAYS produce video while booting the computer BEFORE Windows loads, you have a video cable connection problem of one sort or another
