Windows 10: Stuck in 640 X 480

Troubleshooting a Rockwell program it was suggested to try starting 640 X 480.

When that didn't work I unchecked the box for this and the app still starts in 640 X 480.

Any suggestions?

6220c pseudo 640 x 480 video

pseudo in terms of true resolution, I would love to read comments from users about the 6220c 640 x 480 video resolution, my feeling is this was misrepresented in advertising it is so obviously not a true 640 x 480 I mean you can create a 640 x 480 frame
size from 176 x 144 if you really want to, in the case of 6220c it seems to me this is a 320 x 240 video interpolated by some proprietary manner to 640 x 480 frame size and passed off as such for what purpose that serves I have no idea- I would like to get
the observations of others who have used it what do you think

its absolutely not a VGA image in that it is lower resolution image expanded to fit 640 x 480 frame. If you saw it you would understand in about 2 seconds it is a severely compromised VGA image. Big big difference from an Nseries 640 x 480 and a classic
640 x 480 and wish I knew before I put down the money,

anyone in Singapore want to take it off my hands let me know!

AMD Radeon HD7700 - Stuck at 640 x 480 Resolution


I have a Dell 8500 that I recently upgraded from Microsoft Windows 8.1 Professional to Windows 10 Professional. The upgrade went smooth but after a few days the system would only boot with a resolution of 640x480. The AMD Radeon HD 7700 is connected via DisplayPort to a Dell U2312HM monitor.

I tried every solution that I could find on the Web and still could not resolve the issue. I did a complete uninstall of the latest AMD Windows 10 Drivers. Since the resolution was stuck at 640x480 I was unable to re-install the drivers.

Based on a suggestion from one Windows TenForums I was going to attempt to use another connections on the Dell U2312M monitor. This monitor has a DisplayPort, Mini Display Port and a DVI.

I unplugged the DisplayPort Cable from the AMD Radeon HD 7700 to get a better look at the available connectors. The video card has a DVI, DDMI and DisplayPort. Since I did not have a long enough cable to go to the monitor I plugged the DisplayPort cable back in.

When I re-started the computer the resolution was back to the 1920 x 1080.

I checked with two other friends that were having similar issues with a Dell and HP computer stuck at 640 x 480 and removing an reinserting the DisplayPort Cable. I suspect I would have had the same results if I powered down both the computer and the monitor. In all case the monitors and computers had not been powered down at the same time.

Hope this helps someone.
