OK. I've made some progress from my earlier post...
4:3 Powerstrip Setting for RCA/Proscan
OK, I've tried to read all of the posts in this thread and have looked at ALL of the links found by Google and cannot find an answer to this. THIS IS DRIVING ME MAD!!!
I have a Proscan PS52800 (RCA MM52100) 4:3 HD Monitor that I am trying to get higher resolutions on. I have tried my ATI AIW 8500DV and a nVidia G-force 4200. Here's what I've done so far.
The monitor easily locks onto 640x480 and 80x600 but there was a slightly newer RCA, the MM52110, that supposedly has Wideband component inputs.
I have an RCA DTC-100 connected to the second VGA input. I can watch all forms of HDTV. 1080i is nice and "blinky" so I am seeing 1080i. I think the HDTV STB is doing some type of scaling though because I am not hearing a pop as I change through 480p, 720p and 1080i channels.
I have a Philips Progressive-scan DVD player connected to the Component inputs. Interlaced and Progressive-scan work fine.
My problem is two fold: 1) I know the monitor has non standard VGA scanning but that shouldn't effect the Component inputs. 2) Most of the posts are for 16:9 set including most of Karnis' excellent 12-31-02 post. They work but are overscanned on the sides. I actually want black bars at the top and bottom of my screen so that all of my programs don't stretch the screen when I click "full screen" or I would like a 4:3 display.
As I said before 640x480 and 800x600 work perfectly. 960x540 works, is overscnned but can be fixed perfectly with Powerstrip 3.43.402 and incredibly 1920x1080 (and is nice and "blinky") works, is overscanned and can be fixed with Powerstrip. 1920x1080 only works with the ATI Component adapter, not through VGA.
I do my setups on a Philips 109B 19" monitor that is capable of (an unpublisized) 2048x1536. I have tried 1920x1440i, 1920x1200i, 1600x1200, 1800x1080i 1620x1080i, 1600x1080i, 1200x900i 1200x810i and p, 1080x810i and p, 1080x720i and p, 960x720i and p, 810x540i and p and a few others. I have tried 31.5 33.75, 34, 45 and 48 (800x600 is 48) KHz horizontal scan rates and 29.97, 30, 59.94 and 60 Hz vertical refresh rate. I am trying to hit a 4:3 version of the HDTV rates.
Most of these cause the screen to tear and I loos control of the mouse, though I can still see mouse pointer moving clearly. The ATI has a tendancy to go Virtual Desktop even though I use Powerstrip or Rage3D to add the resolutions. The G-force is a little better but doesn't always like interlaced video. This is all on the Philips. I usually don't get to connecting them to the TV.
All of my drivers are up to date. I assume I am not actually running at a higher resolution but more like squishing more pixels into a scanline (increasing my pixel rate. That's fine with me. I think the DTC-100 is doing the same thing. The 1920x1080i display looks fantastic for video but terrible for text. 960x540p is not much different from 800x600 and is stretched so it's not worth it.
Any help would be greatly appreciated.
Here are the setting I am using:
PowerStrip timing parameters:
Generic timing details for 1920x1080:
HFP=209 HSW=104 HBP=327 kHz=33 VFP=0 VSW=12 VBP=24 Hz=30
Linux modeline parameters:
"1920x1080" 85.465 1920 2129 2233 2560 1080 1080 1092 1116 interlace +hsync +vsync
This fits perfectly on the screen. The desktop is clean, clear and has no under/overscan. What's really been slowing me down is the fact that this resolution doesn't work on the video cards VGA port, even when connected to my 19" Philips monitor that can do 2048x1536. It only works on the ATI DVI to Component adapter. Its definately interlaced because Nokia monitor test blinks 30 times a second on the high-res test. THE PICTURE IS FANTACTIC. Divx, DVDs DirecTV through S-Video actually look better than the VGA sidnal produced by the RCA DTC-100 (though not better than true HDTV). I can easily see MPEG-II artifacts on all channels of DirecTV. The only problem I am having is that all of my multimedia applications think I am running 16:9. Everything will be stretched tall and/or have blank bars on the sides. The only way around this is to force "free aspect" within the application. Then everything looks normal.
What I realy need is a way to set 1440x1080i. That would be 1920x1080i at 4:3. Every time I try to create it, I loose sync.
