Hey there, let's work through this PDF display issue step by step. I get it—frustrating when a PDF that looks totally fine elsewhere goes wonky in an app you're not super familiar with. Here are some practical fixes to try out:

• Double-check PDF import settings
  When you go to File > Open and select your PDF, Photoshop will pop up an "Import PDF" dialog. Pay attention to these key options:

  • Make sure the correct page range is selected (you might be opening a blank or unintended page by mistake)
  • Adjust the Resolution—if it's set too low (like 72dpi), the file will look pixelated or distorted. For most cases, 300dpi is a safe bet for sharp results
  • Match the Color Mode to your original PDF. If the PDF was made for print (CMYK) and you open it in RGB mode, colors might shift unexpectedly
  • Toggle the "Anti-alias" option on/off—sometimes this setting can cause odd rendering artifacts

• Account for vector vs. raster differences
  Many PDFs are vector-based (think files from Illustrator or InDesign), but Photoshop is a raster editor. When you open a vector PDF in PS, it gets rasterized (converted to pixels). If the original has complex vector graphics, incorrect rasterization settings can break the display. Try:

  • Opening the PDF in Illustrator first, then exporting it as a high-resolution PSD or PNG before bringing it into Photoshop
  • Bumping up the resolution in the PS import dialog to minimize rasterization artifacts

• Repair the PDF file
  Even if the PDF looks normal in other viewers, it might have minor corruption that Photoshop struggles with. Use Adobe Acrobat Pro's repair tool: Tools > Scan & OCR > Repair PDF, then save a fresh copy and try opening it in PS again.

• Update Photoshop
  Older versions of Photoshop might lack support for newer PDF standards. Open the Creative Cloud app, check for pending updates to Photoshop, install them, and test the PDF again.

• Try alternative opening methods
  Instead of using File > Open, try dragging the PDF directly onto your Photoshop canvas, or use File > Place Embedded to insert the PDF. Sometimes different import workflows yield better results.
