New laptop in dual monitor configuration

Hi Everyone,
   I hope you all are doing well.

I am making a move from my existing laptop and preparing for a new one, but not sure what to buy.
I have an old school at least 7 years old monitor (LG Flatron W2242S) connected via VGA and another new (Benq EW2440) connected via HDMI.

I thought that the quality of the image is dictated by VGA. I have connected to new monitor via the same VGA and the image quality is also bad, very fuzzy.
Is this then down to onboard graphics on this laptop? I think this is quite poor GPU I checked and it is Intel HD Graphics 4400 or 5000

Once I was in the office and they have 16 or 17" HP business laptops in there, Elite ones with 2x 27" HP monitors on a mounting arm.
The image quality of both monitors (one on HDMI, second on VGA) was identical. I could not see the difference, but of course I was not doing anything graphics related, but videos looked the same. This was on Windows 7/10 systems.

By the way I have frequent problems detecting any monitor connected via VGA to this HP Probook laptop. After a reboot it detects it fine, but when I disconnect then more likely it will not come back.

How should I approach this problem?
Should I stick with the same brand: Dell laptop and Dell monitors to have full signal compatibility?
or should I look for a laptop that has 2 HDMI outputs - it is very rare but I have seen Asus that has HDMI and another micro DisplayPort or something like that.

What would you suggest?
In this scenario I am buying a new laptop and another new HDMI monitor and getting rid of old VGA monitor.

Cheers

Re: New laptop in dual monitor configuration

I am talking about ASUS N551VW with HDMI and mini DisplayPort. I think I will go for it.

But this very good picture quality from VGA on this Elite HP laptop to 27" HP monitor is a mystery to me. I spent hours looking on both screens. It must be some business cool feature. I don't remember the model of these monitors, but they looked pretty expensive - again business range.

Re: New laptop in dual monitor configuration

Are you driving the monitors at the correct resolution? If you're not using the monitors native resolution then you will get a sub-standard image.

Re: New laptop in dual monitor configuration

I think the resolution I was on this LG Flatron is 1680*1050 which is in this monitors spec.
Or maybe 1600x900 which is lower, but I have to reboot to detect it so I confirm.
Will check and come back with that.
Thank you

Re: New laptop in dual monitor configuration

I have checked and it is on 1680x1050 so it must be something else.

DP1 connected 1680x1050+1366+0 (normal left inverted right x axis y axis) 490mm x 320mm
   1680x1050     59.88*+  59.95  
   1280x1024     75.02    60.02  
   1440x900      74.98    59.89  
   1280x960      60.00  
   1152x864      75.00  
   1024x768      75.03    60.00  
   832x624       74.55  
   800x600       75.00    60.32    56.25  
   640x480       75.00    59.94  
   720x400       70.08

Re: New laptop in dual monitor configuration

Well apparently you are connecting it to a DP port through an active DP->VGA adapter, it could be the "DAC" in the adapter that sucks.

Re: New laptop in dual monitor configuration

I understand.

What should I reload on the system to get this VGA monitor detected back?
Once I reconnect it I have never managed to get it back without a reboot.

HDMI monitor is fine.
