Windows 7 vs Windows 10

Recently I purchased 2 only 27 Inch expensive monitors for m  6500. I was disappointed with them as some programs and N1mm  such as SmartSDR, has slightly blurring test, ie the text in the monitors from both  programs was not crisp and easy to read, 
That computer is running windows 10.  My other computer on the 6700  runs Windows 7.
Today I had a computer expert look at other problems on the 2 computers, such as comports in use, and how to get rid of them, and we started to investigate why the new monitors were not as crisp compared with the ones on Windows 7.
Swapping monitors to the Win 7 computer, they were crisp and easy to read.
Trying another windows7 computer the monitors were perfect.
The slight blurriness  was only happening with old software, new software written for 10 was ok.

SmartSDR and N1mm have gone through a large number of updates, has any one checked back to  ensure that programs such as those are now totally suitable for win 10.

I would not have noticed the problem, if I hadn't been able to run the same programs  on win 7 and 10 on 2  computers side by side.

I have gone back to using 2 win 7 computers in the meantime.

Blurriness is a DPI issue.  I suspect the issue is related to automatic DPI scaling in Win10

Sounds like a Video card driver issue to me, Windows 10 has a whole different default built in Driver set and you may need to find the brand and model including hardware version of the Video card and go to there WEB site and download the appropriate Driver.
If your Video is built into your Mother board then go to the mother board's WEB site and download ALL the new WIN10 drivers, this may fix your issues. 

All in All this is not a FLEX issue but rather a Windows 10 issue trying to guess what your Video Card and Monitor is.

I agree that it's a video card driver issue.  I've experienced this with Windows 10 a lot.  Most of the drivers work best when you set the screen resolution to the monitor's native mode.  Unfortunately, that produces some rather small stuff for my "old" eyes.  You can try scaling things up above 100% in the Windows 10 Display Settings, but that, unfortunately, can cause alignment and spacing issues.  I had better luck with Windows 7, but learned how to produce the correct results in 10 through trial and error.

I run 3 4K monitors with Win10 using an NVIDIA card. All are set for 100% scaling but only the big one uses native resolution (3440x1440). The other two smaller monitors are set to match the size of the big one (2560x1440). This way, dragging windows from one monitor to another keeps the same window size. All this is set up in the windows Display Settings app. No issues with any blurring.

The NVIDIA card has its own setup application. I rarely touch that but there's a lot of control and overrides provided there. One setting, "Adjust desktop size and display" gives options for various scaling including aspect ratio, full screen or no scaling. I have no scaling selected for all three.

Other things to think about is the refresh rate which I think can be adjusted somewhere deeper into the windows display settings or in the driver manager settings. Was your windows 10 machine previously a windows 7 machine? No blurring? Latest Windows 10 video drivers loaded?

I have not had a problem with video on Windows 10. My system is a Dell XPS8900 and I use all the Dell certified drivers. Sometimes I'll try an OEM driver but always end up back at the Dell driver because something doesn't work quite right. I'm having a hard time understanding how Windows 10 could be the cause of the problem. Driver? Ya. OS? People would be screaming at the top of their lungs if Windows 10 video was blurry. I just don't see that. The good side of that is your issue can probably be fixed.

If you're using an older computer the drivers for Windows 10 may not be available. It may not perform optimally. I have an old video card in this machine I have in the shack so I lose the HDMI output. Oh well

Thanks for all the messages and advice, this community is wonderful.
Ria, the computers are all only just 2 years old. and Tim what is DPI?.
Reading the comments it is nice to know others have seen a similar problem,.
I will purchase a new good video card, and see how that works. At least then I could run 3 or 4  monitors as at present running SmartSDR and N1MM I start to run out of monitor screen, yes I like to have  SmartSDR and N1mm with as many of the screens open as possible.
I really appreciate all the help
Best wishes

Good luck and let us know how it turns out.

A quick thought...  if the video cards in your other machines are plug-in, maybe you could swap one over to test it out? Might save the cost of a card if that's not the issue.

In 2 years a lot has happened in the video card industry. My 2 year old AMD video card is now on the legacy list.

DPI = dots per inch.  It is a measure of spatial video dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch.
