OT: strange things with new monitor....

[DR]

Strange issues with a new to me Dell monitor.

My old monitor was 24" diagonal with max of 1920 x 1080. Because of vision issues that was never quite right, either sit close without glasses or sit back farther with glasses. If I used 125% a couple programs didn't display pages correctly.

I came across a killer deal on a 27" monitor, max 2560 x 1440. I set it for 1920 x 1080, perfect, until I found a couple of my programs would not start by clicking on their desktop shortcuts. I had to restart the computer to get them to load, and even that wasn't consistent. Plus in CAD some mouse functions didn't respond.


By trying all sorts combinations of screen resolution I found 1920 x 1200 at 125% works like a charm.


Googling on the issue I found s source said the refresh rate of the monitor was wrong. Another source said to verify USB mouse was fully plugged in, and try another mouse, or reload the latest USB driver (which was up to date). Anyway, now I'm a happy camper, but puzzled.


What was this all about?

I have had similar. It seems to be a question of the software, plus some resolutions being less "standard" so that drivers may not handle them well. You might see if there are any new drivers available.

My last laptop had the 1920 x 1200, the new one has 1920 x 1080. Both work fine with all software, but each one clearly has the drivers for it's display. Both worked well with various external monitors as secondary screens.

In my understanding a monitor is just that - a monitor. It is displaying the information from your computer and nothing more. It may not display something correctly if not setup properly. But it should not affect a mouse function.

There may be an issue with the mouse position being correctly displayed if the drivers are not suitable. That happens with high res screens sometimes. The mouse pointer looks like it is "on" the button, but in fact it registers as "off" of it. I think it is a combination of the resolution, pointer size, and user.

You should check the available outputs of your graphics card,if it is stand alone, some of the lower end ones do not run 2560 x 1440. I use a 27" AOC with the 2560 X 1440 native resolution with just the built in graphics of an Athlon 3000G (AM4). Unless you are running a very old Intel with built in graphics that resolution should be achievable. Refresh rates are usually about 60 Hz. Running at 1920 x 1080 is wasting the screens potential.

I have a brand new HP laptop with i7 processor, but graphics are integrated - no separate video card. The max available resolution on the laptop screen is 1920 x 1080.

Run your monitor at the native resolution, increase to 200%, you have a 2.5k monitor, it will require more processing to run smoothly

Possibly related, when I replaced my monitor, I had to upgrade to 'gamer' mouse bc a stock mouse wasn't precise enough.

Also, instead of HDMI, use a Display Port cable, hopefully your GPU has a port for it

Hey, lots of good information here.

My graphics card is an AMD Radeon. I really don't know anything about it. I buy refurbished computers so what is on the computer is what you get. Here's the outfit:

interconnection.org

interconnection is local to me. They're a non-profit that accepts donations from businesses and individuals. They check everything out, computers are reloaded win10 and given a one year warranty with free shipping. Until recently they had a walk in store where you could negotiate a bit. The 27" monitor was $57 out the door.t

Unfortunately, going from a 24 to a 27 is not much of an increase, what you really need is a new pair of glasses with prescription lenses for you to sit at arms length from the monitor. I bought a pair of safety glasses set for exactly that distance and there was an offer on which included a second pair. They wouldn't give me a second pair of safety glasses, but an ordinary pair for free which I keep for use with a computer monitor.
With Windows 10, you can go into "settings" - "display" and check display resolution, using the new monitor, 2560 x 1440 would be the native and best resolution for it. Also, if you have "control panel", you can find "device manager" and look at "display adaptor" and that will tell you about the graphics card Then you can post the name of the card.
Have a look at the video card connections at the rear of the pc, you really need an HDMI cable to run a monitor at 2560 x 1440.

Let me jump in here with a little quirk involving the wireless mouse on my HP laptop. When not using the laptop, I have to keep the mouse a couple feet away from the laptop or it keeps powering up. Move the mouse close to the laptop and it powers up.

[J Tiers]

It senses the signal from the computer and power up only when you seem to be using it, which is when there is an operating computer around.. Nice feature, better battery life, if you remember to move it away. I do not like wireless mice, due to the "battery thing", but many do.

I'd say the problem is your video card / chip. It has a bug and it reconfigures it self and reveals the bug. I'd update the drivers or load the software for the chipset.
