Changing screen rez. I've always wondered...

[Georgetoon]

how do those colored bars even show you what the new rez is going to be?  How can you tell if the rez is even correct?

For instance, I'm running 1680 x 1050. i'd like to maybe turn it up a notch to 1920 x 1080.  when I do this and test it, all I get are colored bars with a question asking if its the correct rez. wha? how the heck can I tell from this? Maybe I'm dense and I'm missing something (definitely probably the situation. )

Oh, and what does the "automatic" setting do?  Take advantage of your graphics card and monitor and automatically set the correct optimum rez?

if you see the colors it means that the image can be showed and the resolution and refresh rate with the video card you have

sometimes the image won't even show but the resolution can work

most times you should follow the manual of the monitor, if it says that it can do a determined resolution just use that

older and some weird newer monitors can report very different values so be sure by using lower values you know that can work, it is a little complicated with the new 16:9 and 16:10 aspect ration but nothing impossible

about the automatic, the auto button on some lcd monitors?

the maximum resolution depends on the monitor and not in the video card itself or at least this days, older video cards had limits to the maximum resolution, this days for many video cards is 2560 or more(dual head with 5000+ pixels width) so the limit is the monitor itself

Just a tip.

Your monitor will look it's best when the resolution is set to whatever the manufacturer recommends.

Guys, thans.:)I just checked the monitor specs on newegg (where I bought it) and I'm already running at max rez. However, the color bars come up when I toggle to a higher rez. but as you pointed out, I won't go beyond what he manufacturer recommends.

Thanks again.  Just sorta wish the rez function worked similar to Windows set up.  Looking at the actual screen in the new rez before committing to it is helpful

Mark, I don't think it's going to hurt anything if you turn it up. If you like it better, and the monitor will do it, go for it.

that is a very dangerous recommendation, specially with crts

you have me confused now, i thought that you were talking about the colored bars in pclinux control center/hardware/setup the graphical server

i don't know about other bars

about the possibility of test a new resolution and jump back if it fails(xp style) kde control center does that

i remember a win xp machine that had problems with the resolution, i changed resolution and never could recover image, system decided to change permanently the resolution and since i couldn't see image on the screen, i couldn't set it again, i had to reinstall xp   

in pclinux you can run XFdrake and set again a value if you don't have gui because you choose a wrong resolution

if you go above the recommended resolution, you may get 'frequency out of range' errors, which can be hard to rectify.

Ok,, I retract this statement and replace it with the one before it.

Chimei WS monitor ..........  LCD monitor so frequency is not in question.

I reckon it would display the higher res, but the picture would not be as sharp.
The pic will be sharpest at native res.

The 22" native res is  1680x1050

Hello georgetoon: it sounds like you are using the pclinuxos control center to change the resolution, and you are right, the colored bars don't seem to change, they only let you know that the configuration that you picked will work. but if you go to "configure your desktop" and go to "computer administration" >"display">"size and orientation" , and change the screen resolution there, you will be able to see the change and will be asked " keep this change or revert back" or something to that effect. Although in my case with a 22 inch LCD running at 1680x1050, I get those ripple lines on my monitor and can only get rid of them by changing to 1600x1200, which makes the screen look "stretched", but no ripples or waves and I still have not figured that one out yet. hope this helps.

Guys, all this does help. The rez I'm running is fine.  But, things looked a little larger due to my being at the office all day on a Win 7 system running 1920 x 1080 rez.  Plus, I think this is a 23" LCD. This is why I thought about punching it up a notch.  I think I may have posted this same question awhile back (dummy me!)

I guess the ultimate solution will be a new monitor that runs 1920 x 1080.  Not now, but, perhaps sometime down the road.

As for changing the rez in the  Administration and not PCC, I'll give that a look again. However, I think this is tied to the PCC settings. So once max rez is set in PCC, the Computer administration won't go any higher than that. Not sure...sorry, I can't double check now as I'm at the office.

I based the 22" on the info in your sig   

Getting the exact model number from the screen will allow it to be checked for native resolution.

"the Computer administration won't go any higher than that. Not sure...sorry, I can't double check now as I'm at the office."

i have seen this on my pc, sometimes i have to set resolution on pcc first to get the right values on kde control center

about the size, i have seen 19" screens doing 1920x1080 so the size is very important here, ideally a 22" or 24" is the best choice

[Georgetoon]

I'm home. Here's a screen shot of the Computer Admin area.  Max rez is 1680 x 1050.  Yes, it appears this is set based on what is done in PCC. 

Not sure I want to push it as 1680 x 1050 is the max rez for this flat panel.

if you go above the recommended resolution, you may get 'frequency out of range' errors, which can be hard to rectify.

And it won't do anything for the display (in fact, may make it worse).  Since the monitor can only display so many dots,  if you send it more, it will skip some and what it chooses to skip may not be what you would choose.
