Windows 7: Recommended Resolution

Yep, that's exactly what we need.

Taking a look at your monitor's manual, your system is correct in stating the native resolution is 1920x1080. The setting I was referring to was Display Settings > Wide Mode, which controls whether the monitor alters the way the image is displayed when the resolution is smaller than 1920x1080. Since you're wanting to use the native resolution, we shouldn't need to worry about changing that setting.

The fix therefore will be in your video card's settings. Windows doesn't really have the settings you will need to change, so you may need to download ATI/AMD's Catalyst Control Center (CCC) if you're using the generic Microsoft drivers. If you already have it, there are a few versions of the CCC software; mainly the one from before ATI was bought out by AMD, the redesigned one from after.

The ATI version:

The AMD Radeon version:
Recommended Resolution-advancedhdtv.png

Note you may need to switch to the "Advanced View" before some settings will show in the older ATI version. The main resolution settings are on the Display Manager page in the ATI version, or Desktop Management > Desktop Properties in the AMD releases. Without seeing what you have there right now I can't give you exact instructions, but there are two main things you want to confirm:

- The desktop resolution is set to 1920x1080 pixels at a refresh rate of 60Hz.

- "GPU Scaling" is disabled or set to "Use centered timings". This will prevent your computer from resizing things on its own - so your 640x480 DOS game will show in the original size instead of being stretched. Not really necessary, but it might help for troubleshooting.

It should be fairly evident what the problem is - the reported resolution might show 1080p@60Hz (overscan) or (HDTV) or similar, if that's the issue. If you can't find the solution, take a few screenshots of your settings or write them down so we have a better idea of what you're seeing.

[edit: Try stormy13's suggestion as well - that's what I was looking for but I couldn't find it in my drivers. The settings I mentioned might also rectify the problem, but that's the more direct route to solve it!]

It's not an HDTV. It's a 16x9 monitor (1920x1080) connected via an HDMI cable.

Overscan is not applicable with DVI connections, that I know of anyway. It is always "pixel-perfect", using 100% of the screen real estate. It certainly isn't even available with my own HD5770 and my two Eizo 1920x1200 monitors (it's grayed out, and you cannot even use that feature).

Just get a DVI cable today and tell us if that fixes the problem.

No more need for discussion until then.

I will get it as soon as I can get to the stores. I'll report back once I see how I make out. Thanks

Hi Solarstarshines, Stormy13 & Invaliderror, Thanks so much for your advice. As I mentioned in an earlier reply, I'm not too tech savvy to this extent, so before I try to figure out your advice I am going to try dsperber's advice and try the DVI cable first. As I mentioned earlier, a friend has the same Dell computer and system, and a similar Dell monitor and is using the VGA cable that came with his monitor and doesn't have the problem. I'll report back. Thanks again

You can save to cost of a cable at the expense of a couple of mouse clicks right now.

Right click on an open spot on the desktop and select "Catalyst Control Center", and once open do the following (may have to click on Preferences and set it to advanced mode),

Recommended Resolution-overscan.png

and set it to 0%, as it is likely set to 15% (no idea why it defaults to there).

Simply will not happen with DVI cable.

Here's my CCC presentation for "digital flat panels" (I'm on my 1-monitor machine, with HD4850 video card running Catalyst 12.6 Legacy and 12.6 CCC, and Eizo S2433W 1920x1200 24" monitor). Note that there simply IS NO WAY TO SCALE THIS TO ANYTHING BUT 100% OF THE PHYSICAL SCREEN SIZE!!!



Your "scaling" presentation for "AMD Vision" is not even available. In fact, what appears to be its equivalent is actually grayed-out and cannot be changed from a setting that specifies "use 100% of the monitor screen".

In fact, even if I check the "enable GPU scaling" box, the "scale image to full panel size item" remains grayed out and checked. I cannot un-check it even if I wanted to!

I repeat my own feeling: if DVI is available on a monitor and also available on the video card, IT SHOULD BE USED!!! HDMI should not be used if DVI is available as an alternative, and HDMI is not required (say to deliver digital audio over HDMI to an external sound system). There is no purpose or value or advantage to using HDMI if you don't have to, and if you have DVI as an alternative.

Myself... I no longer use the HDMI path routing through my AVR, just to get external multi-channel digital audio. And the reason is as I've stated above: (a) 1920x1080 instead of 1920x1200 as my monitor would support, and (b) "miniaturized" postage-stamp 1920x1080 presentation on my Eizo monitor with that HDMI-relay setup.

Instead, I now use the optical S/PDIF output from my sound chip (Realtek ALC892) to feed my AVR that way. No HDMI involved, so I do lose the 7.1 codecs using this approach, but HDTV (which is what I use it for) only has DD5.1 so the optical connection to my AVR works perfectly.

DVI.

Hello dsperber,

These are greyed out due to using VGA. VGA is analog and DVI is digital, so you should be able to access these options using DVI.

GPU-68: How to Configure GPU Scaling Option in AMD Catalyst

Quote:
Requirements to Configure GPU Scaling Option:
  • A digital connection such as a DVI, HDMI or DisplayPort™ must be used
  • The desktop must be set to a lower non-native resolution. Refer to the display device manual to determine the native resolution. This will be important to know when configuring the display to a non-native resolution
Edit: lol sorry dsperber, thought you were the OP. I agree with you on this subject good info

Yes, the VGA cable is an alternative which SHOULD SUPPORT FULL-PANEL PRESENTATION, at the native resolution of the monitor. No scaling should result... same as with the DVI cable.

So my intuition says if you used the VGA cable which came with your monitor instead of the HDMI cable, you would be using 100% of the panel real-estate. No black bars anywhere on any of the edges.

But... you'd be running your monitor in analog mode through a VGA cable, not digital mode... as would be the case with a DVI cable. Yes, I know the monitor will have to convert the analog VGA control via that cable to digital pixels for display because it is a pixel-based display device but it's built to do exactly that, when you use a VGA cable. However you would be getting full-screen 100% scaling as a result, is my prediction.

And you'll get exactly the same 100% scaling result with your DVI cable, except that the monitor's electronics will not have to convert from analog VGA to digital/pixel for display, as the DVI cable is delivering the pure digital DVI-D 1920x1080 output from your video card directly. Pixel-perfect from the get-go.


There is a noticeable difference between how a pixel-based display (like both of our monitors) looks, when fed via VGA analog cable vs. DVI digital cable. Characters of any kind (text in emails or documents, titles under icons, characters on web pages, etc.) will look "painted", whereas those same characters will appear crystal-sharp and clear, with no "edges" or extra width or anything other than pixel-perfect characters.

Believe me... you CAN easily tell the difference when using VGA vs. DVI. The only issue is whether it will bother you (as it did me). The HD4850 I'm using on this machine only had one DVI connector and its second was VGA. So when I first got my second 24" Eizo I was forced to use the VGA connector for the second monitor, and I just didn't like it when compared to how my first 24" Eizo looked via its DVI connection.

That's what prompted me to upgrade my video card for that 2-monitor machine, to a dual-DVI HD5770. And now both the monitors on that machine are connected with DVI cables, and both look pixel-perfect and all-digital. I'm finally happy.

I repeat: I am using a DVI cable, not a VGA cable.

Eizo S2433W monitor, 1920x1200, DVI cable from HD4850 video card.

And I am using the full native "recommended" resolution of my 1920x1200 monitor. Note that your quote shows that GPU scaling is only possible with LESS THAN RECOMMENDED RESOLUTION, something I do not do.

Same with OP's story. He's got a 1920x1080 Dell monitor, and wants to run it at that native "recommended" resolution from his HD5450 video card... with 100% of the screen panel used (i.e. no black edges of unused screen real-estate). And this WILL occur, if only he uses a DVI cable (or a VGA cable as well), but apparently will not occur with his HDMI cable. He's still specified native "recommended" 1920x1080 resolution, so your scaling prerequisite would not apply and it should not be available for him to even configure.
